Detailed Description
In order to make the technical solutions better understood by those skilled in the art, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only partial embodiments of the present application, but not all embodiments. 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 application.
It should be noted that the terms "first," "second," and the like in the description and claims of this application and in the drawings described above are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the application described herein are capable of operation in sequences other than those illustrated or described herein. Furthermore, the terms "comprises," "comprising," and any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
For a better understanding of the embodiments of the present application, some of the terms or expressions appearing in the course of describing the embodiments of the present application are to be interpreted as follows:
IOS voice over function: 1) sliding browsing: sliding left or right, and switching focus among various contents on the screen; 2) touch browsing: touching the screen with a single finger, and dragging the finger to slide over the content until the focus moves to the required content; 3) activating the selected item: double clicking at any position on the screen; 4) scrolling the screen or list: the method comprises the steps of firstly focusing a voice-over focus on any element in a region needing to be scrolled, and then rapidly sliding on a screen by three fingers at the same time.
UIkit: the UIKit provides comprehensive HTML, CSS and JS components, is simple to use and is easy to customize and expand.
UIView (user interface view): the UIView is a basic element forming a picture, is a quadrangle with a position attribute and a certain size, generally has a background color, and can contain content such as character strings or pictures. UIView may have a subclass of UIView types, so UIView may be easily added to UIView to create various pictures.
Accessibility (barrier free access programming interface): two informal protocols and one class are generally included, as follows:
uiaccess availability (user interface barrier free access): and the object implementing the UIAccessability protocol reports the barrier-free access state (namely whether barrier-free access exists) of the object, provides descriptive information about the object, and implements the UIAccessability protocol by standard UIKit controls and views under the default condition.
Uiaccessiitycontainer (user interface view container unobstructed access): informal agreements, a subclass commonly used for UIView, may have some of the child UIs it contains accessed as separate elements. This protocol is useful when the child objects contained in a view are not a subclass of UIView, resulting in an inability to be accessed automatically and without obstruction.
Uiaccessitivelement (user interface element accessible): class, which by default implements the uiaccess protocol, may create an instance of the class for an object that cannot be accessed automatically and without obstruction (e.g., an object that is not a subclass of UIView or does not exist) so that it may be accessed without obstruction.
The attribute describing the user interface barrier-free access element is the core of uiaccess capability, and VoiceOver provides corresponding attribute information when a user accesses or interacts with a control or view. Uiaccess identity defines the following attributes:
label: a short localization word or phrase that is used to briefly describe the control or view, but not to define the element type. Such as "add" or "play".
Traits (characteristics): a combination of one or more individual features, each feature describing some aspect of the state, behavior, or use of the element. For example, an element appears as a Keyboard Key and is currently Selected, and this element may use a combined feature of Keyboard Key (Keyboard Key) and Selected (Selected).
Hint (cue): a brief, localized phrase that describes the result of an element action, such as: "add title" or "open shopping list".
Frame (Frame): the frame of an element is the coordinates of the element on the screen, indicating the position and size of the element on the screen.
Value: a current value of an element when the value cannot be presented using the tag. For example, the label for a slider bar may be "speed," but its current value may be "50%".
It should be noted that, the user information (including but not limited to user device information, user personal information, etc.) and data (including but not limited to data for presentation, analyzed data, etc.) referred to in the present disclosure are information and data authorized by the user or sufficiently authorized by each party.
The solution of the present application is described below with reference to preferred examples.
Example 1
In accordance with an embodiment of the present application, there is provided an unobstructed screen reading method for application to an IOS device, it being noted that the steps illustrated in the flowchart of the figure may be performed in a computer system such as a set of computer executable instructions, and that while a logical order is illustrated in the flowchart, in some cases the steps illustrated or described may be performed in an order different than here.
Fig. 1 is a schematic flow chart of an alternative barrier-free screen reading method according to an embodiment of the present application, and as shown in fig. 1, the method at least includes steps S102-S106, where:
step S102, responding to the touch operation of a target object on a user-defined control in the IOS equipment, and calling a barrier-free screen reading program to read the screen of the user-defined control based on a first application program interface which is configured in advance, wherein the user-defined control is not a subclass of a user interface view, and the first application program interface is used for realizing the access of the barrier-free screen reading program to the user-defined control.
The barrier-free screen reading program can be VoiceOver, which serves as a medium between a user interface in application and user touch control, and can provide audio description for views, controls and the like in application, so that a user can obtain corresponding voice prompt information only by touching a screen, and can completely control equipment without watching the screen, namely, barrier-free screen reading is realized.
Since the custom control is usually not a subclass of the ui view, and cannot be accessed by VoiceOver automatically without any obstacle, at this time, a corresponding first application program interface needs to be configured, and the access of VoiceOver to the custom control is realized by setting the accessibility state of the custom control.
Specifically, the custom control may be a single view or a view container including multiple sub-views, and the following respectively describes the configuration process of the first application program interface in these two cases.
When the user-defined control is a single view, two schemes are provided, and the accessibility state of the single view is set in an implementation interface of the single view or instantiation code of the single view respectively, so that the accessible of the user-defined control by a barrier-free screen reading program is realized.
When the accessibility state of the single view is set in the implementation interface of the single view, a barrier-free access protocol of the user interface element is implemented in the implementation interface of the single view, and the barrier-free access element is returned to 'yes' in the single view, wherein the barrier-free access protocol of the user interface element, namely UIAccessabilityElement, is used for realizing the access of a barrier-free screen reading program to the single view. Specific codes can be referred to as:
-(BOOL)isAccessibilityElement{
return YES；
}
optionally, when the accessibility state of the single view is set in the instantiation code of the single view, assigning a value to the barrier-free access element attribute corresponding to the single view; the "single view to unobstructed access element" is set to "yes". Specific codes can be referred to as:
view.isAccessibilityElement＝YES
when the custom control is a view container comprising a plurality of sub-views, since the sub-views in the view container are required to be accessed rather than the view container, the accessibility states of the sub-views in the view container can be set in the implementation interface of the view container, so that the accessible screen reading program can access the custom control.
In some optional embodiments of the present application, a user interface view container barrier-free access protocol may be implemented in an implementation interface of a view container, where the user interface view container barrier-free access protocol is uiaccessibliitycontainer, and is used to implement access of a barrier-free screen reading program to each sub-view in the view container. Specifically, the following processes can be referred to:
defining a variable array NSMutableArray for storing the accessible elements;
establishing a corresponding number of barrier-free access elements based on the number of the sub-views in the view container, specifying the attribute of each barrier-free access element based on each sub-view information, and adding each barrier-free access element to a variable array, wherein each barrier-free access element corresponds to one UIAccessibilityElement and is used for realizing the access of a barrier-free screen reading program to the sub-views corresponding to the barrier-free access elements;
in the case that the "view container is an unobstructed access element" return "no", the specific code may refer to:
-(BOOL)isAccessibilityElement{
return NO；
}
and returning the number of the sub-views supporting barrier-free screen reading, wherein specific codes refer to:
-(NSInteger)accessibilityElement Count{
return[[self accessibleElements]count]；
}
and returning a directory corresponding to the child view supporting barrier-free screen reading, wherein the specific code can refer to:
-(id)accessibilityElement At Index:(NSInteger)index{
return[[self accessibleElements]object At Index:index]；
}
and returning the attribute of the barrier-free access element under the directory, wherein the specific code can refer to:
-(NSInteger)index Of AccessibilityElement:(id)element{
return[[self accessibleElements]index Of Object:element]；
}
and step S104, when the popup view appears in the IOS device, calling a barrier-free screen reading program to read the popup view based on a second application program interface which is configured in advance, wherein the second application program interface is used for realizing focusing and accessing of the barrier-free screen reading program to the popup view.
It can be understood that when a popup view appears in a device, such as a popup prompt message, VoiceOver needs to focus on the popup view, and preferably implement barrier-free screen reading of the popup view, and at this time, a corresponding second application program interface needs to be configured to implement focusing and accessing of a barrier-free screen reading program to the popup view.
Specifically, when the second application program interface is configured, the property that the "barrier-free access view is a popup" corresponding to the popup view may be set to "yes", so that the focus of the barrier-free screen reading program is focused on the popup view, and the popup view is accessed. Specific codes can be referred to as:
-view.accessibilityViewIsModal＝YES
alternatively, the user may also choose to manually focus the focus to the pop-up view.
In some optional embodiments of the present application, the specific descriptive clear access information may also be viewed based on an Interface Builder window provided by the IOS device, as shown in fig. 2, which shows the clear access information of the text field.
In the embodiment of the application, corresponding application program interfaces are configured in advance and are respectively used for realizing the access of a barrier-free screen reading program to a user-defined control and the focusing and accessing of the barrier-free screen reading program to a popup view, so that the IOS equipment can respond to the touch operation of a target object to the user-defined control, the barrier-free screen reading program is called based on a first application program interface to read the user-defined control, and when the popup view appears in the IOS equipment, the barrier-free screen reading program is called based on a second application program interface to read the popup view, thereby solving the technical problems that the barrier-free screen reading function cannot be realized for the user-defined control in the IOS equipment, and the barrier-free focus penetration is difficult to realize when the page layout is complex.
Example 2
According to an embodiment of the present application, there is also provided an unobstructed screen reading device for implementing the unobstructed screen reading method, as shown in fig. 3, the device at least includes a first screen reading module 30 and a second screen reading module 32, where:
the first screen reading module is used for responding to touch operation of a target object on a user-defined control in the IOS equipment, calling a barrier-free screen reading program to read the screen of the user-defined control based on a first application program interface which is configured in advance, wherein the user-defined control is a subclass of a user interface view, and the first application program interface is used for realizing access of the barrier-free screen reading program to the user-defined control.
Since the custom control is usually not a subclass of the ui view, and cannot be accessed by VoiceOver automatically without any obstacle, at this time, a corresponding first application program interface needs to be configured, and the access of VoiceOver to the custom control is realized by setting the accessibility state of the custom control.
Specifically, the custom control may be a single view or a view container including multiple sub-views, and the following respectively describes the configuration process of the first application program interface in these two cases.
When the user-defined control is a single view, two schemes are provided, and the accessibility state of the single view is set in an implementation interface of the single view or instantiation code of the single view respectively, so that the accessible of the user-defined control by a barrier-free screen reading program is realized.
When the accessibility state of the single view is set in the implementation interface of the single view, the barrier-free access protocol of the user interface elements is implemented in the implementation interface of the single view, and the barrier-free access element is returned to 'yes' in the 'single view', wherein the barrier-free access protocol of the user interface elements, namely UIAccessibilityElement, is used for implementing the access of the barrier-free screen reading program to the single view.
Optionally, when the accessibility state of the single view is set in the instantiation code of the single view, assigning a value to the barrier-free access element attribute corresponding to the single view; the "single view to unobstructed access element" is set to "yes".
When the custom control is a view container comprising a plurality of sub-views, since the sub-views in the view container are required to be accessed rather than the view container, the accessibility states of the sub-views in the view container can be set in the implementation interface of the view container, so that the accessible screen reading program can access the custom control.
In some optional embodiments of the present application, a user interface view container barrier-free access protocol may be implemented in an implementation interface of a view container, where the user interface view container barrier-free access protocol is uiaccessibliitycontainer, and is used to implement access of a barrier-free screen reading program to each sub-view in the view container. Specifically, the following processes can be referred to:
defining a variable array NSMutableArray for storing the accessible elements;
establishing a corresponding number of barrier-free access elements based on the number of the sub-views in the view container, specifying the attribute of each barrier-free access element based on each sub-view information, and adding each barrier-free access element to a variable array, wherein each barrier-free access element corresponds to one UIAccessibilityElement and is used for realizing the access of a barrier-free screen reading program to the sub-views corresponding to the barrier-free access elements;
in "view container is barrier free access element" return "no";
returning the number of the sub-views supporting barrier-free screen reading;
returning a directory corresponding to the child view supporting barrier-free screen reading;
the barrier-free access element attribute under the directory is returned.
And the second screen reading module is used for calling a barrier-free screen reading program to read the screen of the popup view based on a second application program interface which is configured in advance when the popup view appears in the IOS device, wherein the second application program interface is used for realizing focusing and accessing of the barrier-free screen reading program to the popup view.
When the popup view appears in the device, for example, the popup prompt message pops up, VoiceOver needs to focus a focus on the popup view, and preferably implements barrier-free screen reading of the popup view, at this time, a corresponding second application program interface needs to be configured to implement focusing and accessing of a barrier-free screen reading program to the popup view.
Specifically, when the second application program interface is configured, the property that the "barrier-free access view is a popup" corresponding to the popup view may be set to "yes", so that the focus of the barrier-free screen reading program is focused on the popup view, and the popup view is accessed.
In the embodiment of the application, based on the application program interface which is configured in advance, access of a barrier-free screen reading program to a user-defined control and focusing and access of the barrier-free screen reading program to a popup view are respectively realized, so that the IOS device can respond to touch operation of a target object to the user-defined control, the barrier-free screen reading program is called based on a first application program interface to read a screen of the user-defined control, and when the popup view appears in the IOS device, the barrier-free screen reading program is called based on a second application program interface to read the popup view, thereby solving the technical problems that barrier-free screen reading function cannot be realized for the user-defined control in the IOS device, and barrier-free focus penetration is difficult to realize when the page layout is complex.
