Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In the embodiment of the present invention, an IOS operating system provided by Apple Inc (Apple Inc.) is taken as an example to describe the gesture implementation method on the intelligent device provided by the embodiment of the present invention, but a person skilled in the art should understand that the gesture implementation method on the intelligent device provided by the embodiment of the present invention can also be applied to operating systems of other mobile intelligent terminals, such as an Android operating system.
Fig. 1 is a flowchart of a method for implementing a gesture on an intelligent device according to an embodiment of the present invention, and as shown in fig. 1, the method for implementing a gesture on an intelligent device according to an embodiment of the present invention includes:
In the embodiment of the invention, the intelligent device is a device which is provided with a computer operating system and a touch screen and allows a user to perform interactive operation on the touch screen.
The user can realize a plurality of operations on the touch screen, and the operations can be finished by a single finger or a plurality of fingers. The type of operation may also be varied, such as clicking, long pressing, dragging, etc. In an embodiment of the invention, the capture is performed for a single-finger operation of a user on a touch screen.
When the single-finger operation is recognized, a related method in the prior art may be adopted, for example, in an IOS operating system, when a touche event is triggered, it is determined whether the number of fingers is equal to 1, if so, the operation is the single-finger operation, and if greater than 1, the operation is not the single-finger operation.
And after the operation of the user on the touch screen is determined to be the single-finger operation, calculating the movement information of the single-finger operation. As known to those skilled in the art, when a user operates on a touch screen of a smart device, an operating system of the smart device can acquire coordinates of contact points between a finger of the user and the touch screen, and an offset corresponding to a single-finger operation on a target view can be calculated according to the coordinates of the contact points.
For example, in the IOS operating system, the offset in coordinates after the movement of a single finger is obtained by CGPoint translation [ pan translation in view: self ].
The target view is the view that is run on the smart device and acted upon by the user's single finger operation.
After the offset corresponding to the single-finger operation on the target view is obtained, the angle change value of the single-finger operation on the target view can be calculated according to the offset. For example, the transformed center point of the target view is calculated according to the offset of the single finger operation on the target view and the center point of the parent view, and the first arctangent value of the relative position of the target view in the height direction and the second arctangent value of the relative position of the target view in the width direction can be obtained according to the transformed center point coordinate of the target view and the transformed center point coordinate of the target view. And obtaining the angle change value corresponding to the single-finger operation according to the difference value of the first arc tangent value and the second arc tangent value. Although the angle change value is obtained based on the center point, in practical applications, the angle change value may be obtained from a front-rear position conversion relationship of other points.
It should be noted that the single-finger operation is widely applied to the intelligent device, and operations such as writing and page turning all involve the single-finger operation. Therefore, a certain trigger condition, such as a specific function key on a screen, is set before the gesture implementation method provided by the embodiment of the present invention is executed, and the gesture implementation method provided by the embodiment of the present invention is executed only if the trigger condition is satisfied. In other embodiments of the present invention, a process of setting the trigger condition will be described.
And 102, identifying a gesture state corresponding to the single-finger operation.
In the embodiment of the present invention, the gesture state is used to describe whether the gesture is completed at the current time, and specifically, the gesture state includes: the gesture continues to change and the gesture has ended.
The gesture state corresponding to the single-finger operation can be recognized by an operating system of the intelligent device. For example, in an IOS operating system, the IOS operating system may generate pan. Therefore, as long as pan.state generated by the IOS operating system is captured and specific values thereof are obtained, the gesture state corresponding to the single-finger operation can be recognized.
For example, when pan is set to uigesture recogniter statechanged, the gesture is in a continuously changing state (i.e., the gesture is ongoing and has not ended), and when pan is set to uigesture recogniter stateend, the gesture is in a state that has ended.
The gesture state helps the smart device recognize a specific type of single-finger operation. For example, when pan is a uigesture recogniturestatechanged, it is proved that the single-finger operation has not ended at the current time, and then the type of the single-finger operation may be a rotation operation or a zoom operation; when pan is called uigesture recognitionarstateend, it is proved that the single-finger operation has ended at the present time, and the type of the single-finger operation may be a screen capture operation or a sharing operation.
In the embodiment of the invention, a single finger is required to complete relatively complex operations. Because the single-finger operation is widely used in practical application, and the gestures of various types are difficult to distinguish only by depending on the movement information of the single-finger operation on the target view, in the embodiment of the invention, the movement information of the single-finger operation on the target view is combined with the gesture state corresponding to the single-finger operation, so that the gestures of various types are realized, and further, the relatively complex operations corresponding to the gestures of various types are completed.
In the embodiment of the present invention, the type of the first gesture includes one or a combination of the following: zooming operation, rotating operation, screen capturing operation and sharing operation. For example, the zoom operation can be combined with the rotate operation, i.e., the zoom operation and the rotate operation are done simultaneously in one single finger operation. These types of operations will be further described in other embodiments of the present invention.
According to the gesture implementation method on the intelligent device, provided by the embodiment of the invention, through the movement information of the single-finger operation and the gesture state corresponding to the single-finger operation, a single finger can complete relatively complex operations, the user operation is simplified, and the view of the user is not blocked.
Based on any one of the above embodiments, in the embodiment of the present invention, the step 103 further includes:
determining the gesture corresponding to the single-finger operation as a zooming operation according to the movement information of the single-finger operation on the target view and the gesture state corresponding to the single-finger operation;
determining a scaling factor according to the movement information of the single finger operation on the target view;
and scaling the target view according to the scaling coefficient.
In the embodiment of the present invention, the gesture state corresponding to the single-finger operation is that the gesture is in a continuously changing state (i.e., pan is uigesture recogniturestatechanged), and the movement information of the single-finger operation on the target view includes an offset, and if the angle change value is smaller than a preset first angle threshold, the gesture corresponding to the single-finger operation is a zoom operation.
The zoom operation is a zoom operation on the target view. When zooming is carried out, a zooming coefficient is calculated according to the offset of single-finger operation on the target view, after the zooming coefficient is obtained, characters in the target view can be zoomed according to the zooming coefficient, and meanwhile, the zooming coefficient is transmitted to a parent view of the target view, so that the structure of the parent view is changed, and the purpose of zooming the target view is achieved. The parent view is a previous view of the target view, namely a view carrying the target view.
For example, in the IOS operating system, the offset of the single-finger operation on the target view is obtained in real time, then the component transformation.x of the offset on the X coordinate is obtained, the ratio transformation.x/10 between the component transformation.x of the offset on the X coordinate and a custom value (for example, the custom value is set to 10) is obtained, and the ratio is used as the scaling factor.
After the scaling coefficient is obtained, the scaling coefficient is adopted to scale the pointSize for setting the system font size in the font, so that the vector change of the characters in the target view is realized; the zoom factor is also transmitted to the parent view of the target view, and the structure (frame) of the parent view is changed, so that the purpose of zooming the target view is achieved.
The gesture implementation method on the intelligent device provided by the embodiment of the invention realizes that a single finger finishes zooming operation, simplifies user operation, and does not cause view shielding on the user.
Based on any one of the above embodiments, in the embodiment of the present invention, the step 103 further includes:
determining that the gesture corresponding to the single-finger operation is a rotation operation according to the movement information of the single-finger operation on the target view and the gesture state corresponding to the single-finger operation;
obtaining the angle of the target view to be rotated according to the angle change value of the single-finger operation;
and realizing the rotation of the target view according to the rotation angle.
In the embodiment of the present invention, the gesture state corresponding to the single-finger operation is that the gesture is in a continuously changing state (i.e., pan is uigesture recogniturestatechanged), and the movement information of the single-finger operation on the target view includes an offset, and the angle change value is greater than or equal to a preset first angle threshold, then the gesture corresponding to the single-finger operation is a rotation operation.
The following describes the whole process of rotating the target view by taking the IOS operating system as an example to calculate the angle change value of the single finger operation and obtain the rotation angle according to the angle change value.
In the IOS operating system, calculating the coordinates of the center point after the target view is rotated requires adding a relative offset to the x value and y value of the center point of the parent view (i.e. pan. view) of the target view responding to the gesture, respectively, to obtain:
CGPoint newCenter＝CGPointMake(pan.view.center.x+translation.x,pan.view.center.y+translation.y)。
and setting an anchor point, wherein in the embodiment of the invention, the anchor point is defined as a central point before rotation of the target view, so that the anchor point can be set in the following way: center is self.
After the coordinates of the center point after rotation and the coordinates of the anchor point are obtained, the arctangent value is obtained through the height and the width of the relative positions of the center point after rotation and the anchor point:
CGFloat angle1＝atan((newCenter.y-anthorPoint.y)/(newCenter.x-anthorPoint.x))；
CGFloat angle2＝atan((pan.view.center.y-anthorPoint.y)/(pan.view.center.x-anthorPoint.x))。
the difference value is used to find the current rotation angle, i.e., CGFloat angle1-angle2, and then set the current rotation self. Wherein CGAffineTransformRotate () is used to set view rotation; transform is used to represent the rotation matrix of the last rotation operation.
To ensure that the next touch needs to start from the current state, a variable is needed to record the overall rotation value, e.g., self.
The gesture implementation method on the intelligent device provided by the embodiment of the invention realizes that a single finger completes the rotation operation, simplifies the user operation, and does not cause the view shielding to the user.
Based on any one of the above embodiments, in the embodiment of the present invention, the step 103 further includes:
and transmitting the rotation angle to a parent view of the target view, and realizing the rotation of the parent view according to the rotation angle.
In the embodiment of the present invention, the target view has a parent view and has a positional association relationship with the parent view, so after the target view is rotated, the parent view needs to be rotated similarly. Therefore, in the embodiment of the present invention, the calculated rotation angle needs to be transmitted to the parent view, so as to implement the rotation of the parent view.
The gesture implementation method on the intelligent device provided by the embodiment of the invention realizes that a single finger completes the rotation operation, simplifies the user operation, and does not cause the view shielding to the user.
Based on any one of the above embodiments, in the embodiment of the present invention, the step 103 further includes:
determining that the gesture corresponding to the single-finger operation is screen capturing operation according to the movement information of the single-finger operation on the target view and the gesture state corresponding to the single-finger operation;
and executing screen capture operation.
In this embodiment of the present invention, if the single-finger operation that triggers the screen capture operation is circling, the determining that the gesture corresponding to the single-finger operation is the screen capture operation according to the movement information of the single-finger operation on the target view and the gesture state corresponding to the single-finger operation further includes:
when the gesture state corresponding to the single-finger operation is that the gesture is finished (i.e., pan. state is uigesture recognitionarstateend), and the angle change value included in the movement information of the single-finger operation on the target view is greater than or equal to a preset screen capture trigger angle threshold value, determining that the gesture corresponding to the single-finger operation is the screen capture operation. Specifically, the gesture corresponding to the single-finger operation is circling and screen capturing.
When the screen capturing operation is carried out, related function functions in an operating system of the intelligent equipment can be called to realize the screen capturing.
For example, in an IOS operating system, when a rotation angle corresponding to a single-finger rotation operation exceeds 360 degrees (a specific trigger angle value can be set according to user habits), a uigraphics begingimagecontext within operations for screenshot is triggered to operate a current context, and then a parent view of a pan gesture is used to call renderInContext for rendering a view layer into the currently drawn context (i.e. screenshot), so that a screenshot of the current control (for a single-level view, the target view is the current control; if the target view has a child view (another view is carried on the target view) or a parent view (one view carries the target view) or a child view is also carried on the child view of the target view, etc., the whole view level with a bearer relationship is the current control) can be generated, and if the parent view is the whole page, the whole screen is intercepted.
In the embodiment of the present invention, the single-finger operation for triggering the screen capture operation is a circle, and in other embodiments of the present invention, the single-finger operation for triggering the screen capture operation may be other types of operations. Such as drawing a nine-palace line, drawing a triangle, drawing a pair of hooks, drawing a fork, etc. As long as the operating system of the intelligent device can realize the specific screen capturing operation triggering action, the screen capturing operation can be triggered, and the purpose of triggering the screen capturing operation by a single finger is achieved.
The gesture implementation method on the intelligent device provided by the embodiment of the invention can complete screen capture operation by a single finger, simplifies user operation and does not cause view shielding on the user.
Based on any one of the above embodiments, in the embodiment of the present invention, the step 103 further includes:
when the gesture state corresponding to the single-finger operation is that the gesture is finished (i.e., pan. state is uigesture recognitionarstateend), and the offset included in the movement information of the single-finger operation on the target view is greater than or equal to the sharing trigger threshold, determining that the gesture corresponding to the single-finger operation is a sharing operation;
executing a sharing operation, specifically including: and calling a UIGraphic BeginImageContextWithOptions function for the operation context and a renderInContext function for screenshot to realize screenshot operation, and then sharing the result of the screenshot operation.
In a specific embodiment, if the single-finger operation triggering the sharing operation is a slide-up operation, the step of setting the offset included in the moving information of the single-finger operation on the target view to be greater than or equal to the sharing trigger threshold includes:
the component of the offset on the target view in the vertical direction according to the single-finger operation is greater than or equal to the sliding share trigger threshold.
The component of the offset of the single finger operation on the target view in the vertical direction can be obtained by the prior art. After the component is obtained, the component is compared with the upglide sharing trigger threshold, and if the component is greater than or equal to the upglide sharing trigger threshold and the gesture state corresponding to the single-finger operation is that the gesture is finished, the gesture corresponding to the single-finger operation can be determined to be the sharing operation.
When the sharing operation is executed, firstly, the screenshot operation needs to be triggered, and then the result of the screenshot operation is shared. In the previous embodiment of the present invention, the detailed implementation of the screenshot operation has been described in more detail, and therefore, the detailed implementation is not repeated here. And after the result of the screenshot operation is obtained, calling a corresponding function module in the intelligent equipment operating system to realize sharing.
For example, in an IOS operating system, a one-touch sharing may be implemented by setting a single-finger up-slide operation. Assuming that the upglide sharing trigger threshold is 200px, when pan2 (after sliding), view. And after the current whole screen is captured, displaying the sharing bullet frame.
The gesture implementation method on the intelligent device provided by the embodiment of the invention can finish sharing operation by a single finger, simplifies user operation and does not cause view shielding on the user.
Based on any one of the above embodiments, in an embodiment of the present invention, before step 101, the method further includes:
and setting a first gesture supporting single-finger operation for the control to which the target view belongs.
The zoom operation, the rotation operation, the screen capture operation or the sharing operation performed by a single finger as described in the foregoing embodiment of the present invention is not supported in the operating system of the existing smart device. Therefore, before step 101, a first gesture supporting a single-finger operation needs to be preset, and the first gesture may be a zooming operation, a rotating operation, a screen capturing operation or a sharing operation completed by the aforementioned single finger.
For example, in the IOS operating system, when the control to which the target view belongs satisfies usernectionenabled YES (i.e. YES in response to the determination result of the user event), a first gesture is added to the control to which the target view belongs, the first gesture is a uipangesturrecognizer gesture for representing a drag operation, and the maximum support number maximum number of gestures of the first gesture is set to 1.
According to the gesture implementation method on the intelligent device, the first gesture supporting single-finger operation is set for the control to which the target view belongs, so that the control to which the target view belongs can support the first gesture implemented in a single-finger operation mode, and a foundation is laid for simplifying user operation.
Fig. 2 is a schematic diagram of a gesture implementation apparatus on an intelligent device according to an embodiment of the present invention, and as shown in fig. 2, the gesture implementation apparatus on the intelligent device according to the embodiment of the present invention includes:
