body: <p>How can I check the end of animation using FLAnimatedImage?
  I have this code:</p>
  
  <pre><code>@property (weak, nonatomic) IBOutlet FLAnimatedImageView *animatedImageView;
  
  NSURL *url1 = [[NSBundle mainBundle] URLForResource:@"hand" withExtension:@"gif"];
      NSData *data1 = [NSData dataWithContentsOfURL:url1];
      FLAnimatedImage *animatedImage1 = [FLAnimatedImage animatedImageWithGIFData:data1];
      self.animatedImageView.animatedImage = animatedImage1;
      self.animatedImageView.contentMode = UIViewContentModeScaleAspectFit;
  </code></pre>
