方法1:
用这种方法退出后台再回来会消失.

CGRect frame1 = a.frame;
frame1.origin.x = -a.width - 10;

DLog(@"结束动画");
方法2:

frame.origin.x = CGRectGetWidth(_portrait.frame)+4 + _name.width;
_name.frame = frame;
[self paomaXunHuan];
}];
}
- (void)paomaXunHuan{
if (!self.isOpen) {//关了
return;
}
[UIView transitionWithView:self duration:6 options:UIViewAnimationOptionCurveLinear animations:^{
