推荐答案

从iOS 5中，不再需要上述方法。只需将 alertViewStyle 属性设置为适当的样式（ UIAlertViewStyleSecureTextInput ， UIAlertViewStylePlainTextInput 或 UIAlertViewStyleLoginAndPasswordInput ）。

From iOS 5 the approach above is no longer necessary. Just set the alertViewStyle property to the appropriate style (UIAlertViewStyleSecureTextInput, UIAlertViewStylePlainTextInput, or UIAlertViewStyleLoginAndPasswordInput).

示例：

UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"Email" message:@"Enter your email:" delegate:self cancelButtonTitle:@"Cancel" otherButtonTitles:@"Ok", nil];
alertView.alertViewStyle = UIAlertViewStylePlainTextInput;
[alertView show];

，您可以将回复为

-(void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex
{
    UITextField *emailTextField = [alertView textFieldAtIndex:0];
    NSLog(@"%@",emailTextField.text);
}
