UITapGestureRecognizer（手势三部曲）
//1、创建手势
UITapGestureRecognizer *r1 = [[UITapGestureRecognizer alloc] init];
//2、手势触发事件
[r1 addTarget:self action:<#(SEL)#>];
//3、把手势应用在哪
[self.window addGestureRecognizer:r1];
启动动画
[UIView animateWithDuration:<#(NSTimeInterval)#> animations:<#^(void)animations#> completion:<#^(BOOL finished)completion#>]
