UIAextField内部的UIAlertView无法在iOS4.1中运行，并且可以在3.0中运行 [英] UITextField inside an UIAlertView not working in iOS4.1 and works in 3.0

问题描述

我在UIAlerView中添加了一个UITextField（将用户添加到列表中，其中包含昵称，并且警报视图会询问昵称。）。这在iOS3中完美运行，但是我无法在iOS4.1中键入UITextField。在iOS4.1中，我确实专注于alertview内的文本字段，并且键盘出现，但输入不起作用。

I have a UITextField added to an UIAlerView (Kind of adding user to list with nick name, and nickname is asked by the alertview.). Thats work perfect in iOS3, But I cant type to that UITextField in iOS4.1. in iOS4.1 I do get focus to that textfield inside alertview, and keyboard appears, however typing doesn't work.

请帮助解决这个问题。

推荐答案

在iOS 4中，UIAlertViews将自动移动并调整大小以避免键盘，如果它们在子视图中包含任何UITextFields，那么您不必自己动手吧。只需添加如下文本字段：

In iOS 4 UIAlertViews will automatically be moved and sized to avoid the keyboard if they contain any UITextFields in their subviews so you don't have to move it yourself. Simply add a text field like so:

UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Hello"
                                                message:@"Tap below to enter text:\n\n"
                                               delegate:nil
                                      cancelButtonTitle:@"Dismiss"
                                      otherButtonTitles:nil];
UITextField *textField = [[UITextField alloc] initWithFrame:CGRectMake(12, 68, 260, 30)];
[textField setBorderStyle:UITextBorderStyleRoundedRect];
[alert addSubview:textField];
[textField release];
[alert show];
[alert release];

一定要添加\ n来为文字字段腾出空间，你必须要玩将球场放在正确的位置。

Be sure to add \n's to make room for your text field, you'll have to play around with getting the field in the correct position.
