Optional set the initialize page by invokesetInitializePageIndex:method
-
Use for static Image
Conforms protocolPBViewControllerDataSourceand implementviewController:imageForPageAtIndex:selector
-
Use for web image
Conforms protocolPBViewControllerDataSourceand implementviewController:presentImageView:forPageAtIndex:selector
-
Handle action
Conforms protocolPBViewControllerDataSourceand implementviewController:didSingleTapedPageAtIndex:presentedImage:orviewController:didLongPressedPageAtIndex:presentedImage:handle single tap or long press action
