Embodiment 1:
As it is shown in figure 1, the invention provides a kind of picture system of selection.Wherein, step 1,2,3,4,5,6 be other for the present invention
The open interface that developer provides is used for customizing this picture selector.Detailed step is as follows:
Step 1 calls, for developer, the instantiation interface that the present invention provides, and act as creating one and was not provided with any attribute
Picture selector (present invention), corresponding interface method :+(instancetype) photoPicker (returns an empty choosing
Select device example).
Step 2 arranges interface (can not set, be defaulted as 10) for the present invention for the preview picture number that developer provides, if
Number is set and then takes all local pictures as preview graph more than local picture number, such as local blank of then showing without picture.Interface belongs to
Property is: previewCount(int type variable)
Maximum picture that step 3 provides for developer for the present invention (dimension of picture after selection, not preview graph size) physics
Size arranges interface (can not set, be defaulted as picture life size), if local picture physical size is less than arranging size, selects
Artwork size, then artwork is beforehand with corresponding uniform zoom if greater than arranging size.Interface attributes is: targetSize
(CGSize type variable)
Step 4 arranges interface (can not set, acquiescence is not compressed) for the present invention for picture quality compression (0 ~ 1) that developer provides.
Interface attributes is: quality(CGFloat type variable)
Step 5 is for the present invention for arranging of providing of the developer belonging positions that preview graph is local pictures (in chronological order: just
Sequence, inverted order), it is defaulted as inverted order arrangement.Interface attributes is: sortDescriptor(int type enumerated variable)
Step 6 can select picture upper limit quantity, by special algorithm (by this map for the present invention for what developer provided simultaneously
Preview graph quantity and sortord that sheet quantity and developer are arranged are that restrictive condition carries out do-while circulation to local picture
Traversal) determine that user can not continue to carry out unchecked picture if user has selected picture number equal to the upper limit arranged the most
Point selection operation and make corresponding prompting, at this moment the picture chosen can be carried out cancelling and selects operation by user.Interface attributes
For: requirCount(int type variable)
Step 7,8 by being similar to the algorithm of step 6, arrange acquisition accordingly according to step 2,3,4,5,6 developers corresponding
By " fetchAssetsWithOptions " function of iOS to the pretreatment in terms of dimension of picture during picture, then asynchronous
Picture is done quality compression by thread process.
Preview graph is added on the rolling view of a lightweight by step 9, and coordinates corresponding operation button to insert
The mode entered is presented in user's current interface, and user is still it can be seen that current interface, and the present invention does not use the biggest
The picture selector of most similar types replaces the mode of whole current page like that, thus gives one friendly vision of user
And interactive experience.
