IOS7中使用UIAlertViews的字符串长度限制？ [英] String Length Limitation with UIAlertViews in IOS7?

问题描述

我正在使用新的iOS应用程序，我注意到在iOS7环境中安装应用程序存在以下问题。

I'm working in a new iOS app and I noticed the following issue installing the app in iOS7 environment.

第一次打开应用程序后，我们的应用程序显示需要接受AGB的弹出窗口才能开始使用它。
我们使用了 UIAlertView ，直到我们用iOS7测试它才能正常工作。实际上警报弹出并且似乎有内容，因为我可以看到一个巨大的滚动条！但奇怪的是文本根本没有显示....在播放了一些文字之后我注意到iOS7的新 UIAlertView 有某种字符串长度限制...

After opening the app by first time, our app displays a popup with the AGB's that needs to be accepted in order to start using it. We used a UIAlertView and it worked fine until we tested with iOS7. Actually the alert pops up and seems to have content since I can see a huge scrollbar! But the strange thing is that the text is not shown at all.... After playing a bit with the text I noticed that the new UIAlertView of iOS7 has some kind of string length limit...

还有其他人注意到了吗？这是正常的，还是iOS 7的错误？

Has anybody else noticed that? Is this normal, or an iOS 7 bug?

我发现自定义 UIAlertView 有效，但如果可能，我宁愿使用原生API。

I found that custom UIAlertView works, but I would rather use a native API if possible.

推荐答案

我遇到了同样的UIAlertView问题，在模拟器中，scrollview足够大，可以容纳长文本但文本不存在。在iphone alertview上尝试显示相同的长度消息后，确实显示了该消息。

I encountered with the same UIAlertView problem, where in the simulator the scrollview was big enough to hold the long text but text was not there. After I tried the show same lenght message on iphone alertview did show the message.

因此，我认为这是一个模拟器问题，而不是真正的限制，这就是没有记录的原因。

Therefore, I think this is a simulator issue, not really a limitation, and that is why it is not documented.
