问题

在gif图显示过程中,手动调用 stopAnimating方法,当再次显示该gif图时,会在定时器的step的方法中crash掉,望看下,3Q `- (void)stopAnimating { [super stopAnimating]; [_requestQueue cancelAllOperations]; _link.paused = YES; self.currentIsPlayingAnimation = NO; }` ![image](https://cloud.githubusercontent.com/assets/10513969/21710156/d801665a-d421-11e6-98d3-953aaccc9fe7.png)
