+/**
+ An image view for displaying animated image.
+ 
+ @discussion It is a fully compatible `UIImageView` subclass.
+ If the `image` or `highlightedImage` property adopt to the `YYAnimatedImage` protocol,
+ then it can be used to play the multi-frame animation. The animation can also be 
+ controlled with the UIImageView methods `-startAnimating`, `-stopAnimating` and `-isAnimating`.
+ 
+ This view request the frame data just in time. When the device has enough free memory, 
+ this view may cache some or all future frames in an inner buffer for lower CPU cost.
+ Buffer size is dynamically adjusted based on the current state of the device memory.
+ 
+ Sample Code:
+ 
+     // ani@3x.gif
+     YYImage *image = [YYImage imageNamed:@"ani"];
+     YYAnimatedImageView *imageView = [YYAnimatedImageView alloc] initWithImage:image];
+     [view addSubView:imageView];
+ */
+@interface YYAnimatedImageView : UIImageView
+
+/**
+ If the image has more than one frame, set this value to `YES` will automatically 
+ play/stop the animation when the view become visible/invisible.
+ 
+ The default value is `YES`.
+ */
+@property (nonatomic) BOOL autoPlayAnimatedImage;
+
+/**
+ Index of the currently displayed frame (index from 0).
+ 
+ Set a new value to this property will cause to display the new frame immediately.
+ If the new value is invalid, this method has no effect.
+ 
+ You can add an observer to this property to observe the playing status.

+/**
+ Whether the image view is playing animation currently.

+ all future frame image into an inner buffer. If this property's value is 0, then 
+ the max buffer size will be dynamically adjusted based on the current state of 
+ the device free memory. Otherwise, the buffer size will be limited by this value.
