延迟后运行的UIAlertAction处理程序

问题描述

我正在尝试将UIAlertViews更改为UIAlertControllers。我为它设置了这个动作：

I'm trying to change my UIAlertViews to UIAlertControllers. I set up this action for it:

UIAlertAction *undoStopAction = [UIAlertAction actionWithTitle:@"Undo Stop"
                                                        style:UIAlertActionStyleDefault
                                                       handler:^(UIAlertAction *action) {
                                                           [self undoStop];
                                                       }];

但是，处理程序在点击操作后大约一秒钟才会运行。有什么方法可以加快速度吗？

But, the handler doesn't run until about a second after the action is tapped. Is there any way to speed this up?

推荐答案

警报视图的短暂延迟是正常的（不到一秒钟）。如果这对您不方便，您可以通过编程方式创建一个覆盖屏幕的视图，其中包含标签和按钮，基本上是一个自定义的警报视图。

The short delay is normal for Alert View (less than a second though). If this is not convenient for you, you can programmatically create a view that covers the screen with a label and a button, basically a customized alert view.
