UIAlertView不显示 [英] UIAlertView not showing

问题描述

我的一个UIAlertViews有一个小问题.我正在尝试显示它，执行一些任务，然后自动将其关闭.这是我当前正在使用的代码:

I have a small problem with one of my UIAlertViews. I'm trying to show it, do some tasks, and then dismiss automatically. This is the code I'm using currently:

callingTaxi = [[UIAlertView alloc] initWithTitle:@"" message:@"検索中" delegate:nil cancelButtonTitle:nil otherButtonTitles:nil, nil];
[callingTaxi show];
/* Do some tasks */
[callingTaxi dismissWithClickedButtonIndex:0 animated:YES];
[callingTaxi release];

但是，UIAlertView仅显示一半.我可以看到背景变暗，但是在任务完成后，警报视图迅速出现，然后又消失了.

However, the UIAlertView only shows half-way. I can see the background darken, but then after the tasks have completed, the alert view quickly appears and then disappears, again.

有什么想法可以解决这个问题吗?

Any ideas how to solve this issue?

推荐答案

它确实显示了，但是您可以立即将其关闭，而不必等待用户使用它来做某事

It does show, but you dismiss it right away, instead of waiting for the user to do something, with

[callingTaxi dismissWithClickedButtonIndex:0 animated:YES];

iOS没有时间完全渲染它.无论如何，这不是应该使用dismissWithClickedButtonIndex的方式.您想在这里实现什么?

There is no time for iOS to render it completely. Anyway, this is not how dismissWithClickedButtonIndex is supposed to be used. What are you trying to achieve here?

我想您需要为UIAlertView分配一个委托，并让委托处理AlertView内部发生的事情.

I guess you need to assign a delegate to the UIAlertView, and let the delegate handle what happens inside the AlertView.
