iOS5：有人设法修复UIAlertView三个按钮和文本字段（UIAlertViewStylePlainTextInput）？ [英] iOS5: Has somebody managed to fix UIAlertView with three buttons and textfield (UIAlertViewStylePlainTextInput)?

问题描述

苹果真的搞砸了这个。我想用新的 UIAlertViewStylePlainTextInput 风格使用 UIAlertView ，并且有三个按钮。结果如下：

Apple really screwed this one up. I want to use a UIAlertView with the new UIAlertViewStylePlainTextInput style and have three buttons in it. The result looks as follows:

有人设法建立一个解决方法，直到苹果公司解决这个问题？也许减少按钮高度不知何故或增加警报视图的总高度？

Has somebody managed to build a workaround until Apple will have fixed this issue? Maybe reducing the button height somehow or increase the total height of the alert view?

推荐答案

这不是一个完整的解决方案，让您开始。

This is not a complete solution but it may get you started.

UIAlertView view = new UIAlertView ("Alert", "This is an alert\n\n\n", null, "Login", "One", "Two");

UIView theTextField = new UIView (new RectangleF (12.0f, 80.0f, 260.0f, 25.0f));
UITextView txt = new UITextView (new RectangleF (0f, 0f, 260.0f, 25.0f));
txt.BackgroundColor = UIColor.White;
theTextField.AddSubview (txt);
view.AddSubview (theTextField); 

view.Show ();

我观察到当你添加一个文本视图作为一个子视图时，AlertView试图聪明。但是如果你把一个通用的UIView作为一个容器，它给你一些更有用的东西。

I observed that the AlertView tries to be intelligent when you add a text view as a sub view. But if you put a generic UIView in as a container it gives you something more useable.

我也验证了这是XCode中的一个问题。

I also verified that this is a problem in XCode.
