这种View叫做HUD（Heads Up Display），一般用于显示当前状态。

@Kymair 这个光有个形，怎么让它比如出现 2 秒后自动消失呢？
@xatest 这两个都是 iOS 的啊，有 Mac 上的例子吗？

谢谢！

谢谢各位！自动消失用 NSTimer 实现了。

- (void)hideViewAnimated:(BOOL)animated {
[self.timer invalidate];

if (animated) {
[UIView beginAnimations:nil context:nil];
[UIView setAnimationCurve:UIViewAnimationCurveEaseOut];
[UIView setAnimationDelegate:self];
[UIView setAnimationDidStopSelector:@selector(hideViewDidStop:finished:context:)];

self.alpha = 0.0;

[UIView commitAnimations];
} else {
self.alpha = 0.0f;
self.hidden = YES;

[self removeFromSuperview];
}
}

Xcode这个提示是好像是来自notification center，似乎不是自己实现的
