uialertview textfield invisible ios 10.1.1

Question

我有UIAlertView和文本字段。

UIAlertView *corrmsg=[[UIAlertView alloc] initWithTitle:@"" message:@"Enter Password" delegate:self cancelButtonTitle:@"Cancel" otherButtonTitles:@"OK",@"Forgot Password", nil];
    corrmsg.alertViewStyle = UIAlertViewStylePlainTextInput;
    [corrmsg show];
    [corrmsg release];

在iPad上iOS 10.1.1文本字段变得不可见，没有光标，没有框，虽然键盘出现并且工作正常，如果你只是盲目输入。

任何人都知道如何解决这个问题？

切换到UIAlertController，但没有帮助:(

        UIAlertController *alertController=[UIAlertController alertControllerWithTitle:@"" message:@"Enter Password" preferredStyle:UIAlertControllerStyleAlert];

    [alertController addTextFieldWithConfigurationHandler:^(UITextField *textField){
        textField.placeholder = NSLocalizedString(@"Enter Password", @"Password");
     }];

    [alertController addAction:[UIAlertAction actionWithTitle:@"OK" style:UIAlertActionStyleDefault handler:^(UIAlertAction *action) {
        [self okBttn:alertController.textFields.firstObject.text];
    }]];
    [alertController addAction:[UIAlertAction actionWithTitle:@"Forgot Password" style:UIAlertActionStyleDefault handler:^(UIAlertAction *action) {
        [self forgotPasswordBttn];
    }]];
    [alertController addAction:[UIAlertAction actionWithTitle:@"Cancel" style:UIAlertActionStyleDefault handler:^(UIAlertAction *action) {
        [self cancelBttn];
    }]];
    [self presentViewController:alertController animated:YES completion:nil];
    [alertController release];

更新：提升部署目标＆gt; 9.0修复了UIAlertController！

你在哪里配置UIAlertView *myAlertView = [[UIAlertView alloc] initWithTitle:(@"") message:@"Enter Password" delegate:self cancelButtonTitle:@"Cancel" otherButtonTitles:@"OK", nil]; myTextField = [[UITextField alloc] initWithFrame:CGRectMake(12.0, 45.0, 260.0, 25.0)]; [myTextField setBackgroundColor:[UIColor whiteColor]]; [myAlertView addSubview:myTextField]; [myAlertView show]; [myAlertView release]; } ？ 试试这样的smthn：
