APNGKit

Add

• Xcode 9 (Swift 3.2 and Swift 4) compatible.

Fix:

• Frame image now respect image scaling when initialized with a scale option.

Fix:

• An issue which causes crashing when initialize APNGImageView with frame.

Fix:

• Set intrinsicContentSize to have better layout support.

Fix:

• An issue which might crash when deinit APNGImageView in macOS

Add:

• Support macOS as target.

Fix:

• Now you could specify the bundle you want to search in when loading an APNGImage with name.

Fix

• Use a GCD-based timer to update APNG animation. This should solve a potential problem that the animation being stuck while performing some heavy drawing work.

Fix:

• An issue which prevents APNGKit to be compiled within a bundler context.

Fix:

• Remove using of setjmp to be compatible with Swift 3.1.

This is a compatible release for Swift 2.3.
Do not use it if you are using a newer version of Swift

Add:

• Expose frameCount of APNGImage.

Fix:

• Setting APNGImageView's image to nil will now remove the content being displayed.

Fix:

• Now an invalid png file will not cause a fatal error. Instead you will get a nil when trying to create an APNGImage with non-png data. #29

Add:

• A new way to load image progressively. It will only load the current frame instead of all at once. This could reduce the memory usage dramatically. If you are trying to load large APNG images, you could try to add this option when creating an APNGImage.
• A delegate method for animation finishes.

Fix:

• A potential issue which causes memory usage is large then expected.

Fix: A problem when alpha blending used in APNG image, which causes alpha decoding not working correctly. #23

Update libpng to 1.6.25

Add: allowAnimationInScrollView property on APNGImageView to enable animated PNG images keep animated during scrolling.
Fix: Now submodule is using "https" protocol instead of "git".

Fix: Removed unnecessary "update version" phase to prevent achieving failing when used as a subproject.
