Unbalanced calls to begin/end appearance transitions for <>
一个动画没有执行结束，下一个动画就开始了。 解决办法 自定义tabbar实现如下方法 问题即可解决：
-(void)viewWillAppear:(BOOL)animated
{
[self.selectedViewController beginAppearanceTransition: YES animated: animated];
}
-(void) viewDidAppear:(BOOL)animated
{
[self.selectedViewController endAppearanceTransition];
}
-(void) viewWillDisappear:(BOOL)animated
{
[self.selectedViewController beginAppearanceTransition: NO animated: animated];
}
-(void) viewDidDisappear:(BOOL)animated
{
[self.selectedViewController endAppearanceTransition];
}
