访问 UIAlertController 的文本字段 - swift ios8 [英] Access textfield of UIAlertController - swift ios8

问题描述

我正在尝试访问 UIAlertView 的文本字段，我正在使用 textFields 属性，我从 textFields 属性获得以下输出:

I'm trying to access the text field of a UIAlertView and I'm using the textFields property and I get the following output from the textFields property:

<_UIAlertControllerTextField: 0x7fe911f96790; 
frame = (4 4; 231 16);  
text = 'THIS IS THE TEXT THAT I JUST ENTERED';  
clipsToBounds = YES; opaque = NO;  
gestureRecognizers = <NSArray: 0x7fe914215cc0>;  
layer = <CALayer: 0x7fe911f96c40>>

如您所见，文本确实显示了，但我需要单独显示文本.textFields.text 将不起作用，因为它已被弃用且不能在 Swift 中使用.

As you can see the text does show up, but I need the text separately. textFields.text won't work because its deprecated and cannot be used in Swift.

推荐答案

textField 存储在 AnyObject 数组中.如果您想访问文本，您应该首先将其转换为 UITextField:

The textFields are stored in an Array of AnyObject. If you want to access text you should cast it as a UITextField first:

((alert.textFields[0] as UITextField).text)
