iOS 编辑 Uialertview 的 TextField

Question

代码:

UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"Name your Search" message:@"Save Search as" delegate:nil cancelButtonTitle:@"Cancel" otherButtonTitles:@"Ok", nil] ;
                alertView.tag = 20;
                alertView.delegate = self;
                alertView.cancelButtonIndex = 1;
                alertView.alertViewStyle = UIAlertViewStylePlainTextInput;
                [alertView show];

- (BOOL)alertViewShouldEnableFirstOtherButton:(UIAlertView *)alertView
{
    if(alertView.tag == 20){
        UITextField *textField = [alertView textFieldAtIndex:0];
        textField.text = @"testing";
        if ([textField.text length] == 0){
            return NO;
        }
    }
     return YES;  
}

我创建了一个带有 TEXTINPUT 模式的 UIALERVIEW。我确实在文本框中设置了文本值。它不允许我在出现警报 View 时编辑文本字段值。我的代码有什么问题？提前致谢

添加这一行:textField.userInteractionEnabled = YES;

在这一行之后:textField.text = @"testing";
