UIAlertView Ok按钮不可见

Question

以下是我用来创建AlertView的代码。但是Ok按钮不可见。

 UIAlertView *prompt = [[UIAlertView alloc] initWithTitle:@"Reset Password" 
                                                     message:@"\n\n" // IMPORTANT
                                                    delegate:self 
                                           cancelButtonTitle:nil 
                                           otherButtonTitles:OTHER_BUTTON_OK, nil];

    prompt.tag=RESET_PASSWORD;
    txtOldPwd = [[UITextField alloc] initWithFrame:CGRectMake(12.0, 50.0, 260.0, 25.0)]; 
    [txtOldPwd setBackgroundColor:[UIColor whiteColor]];
    [txtOldPwd setPlaceholder:@"Old Password"];
    txtOldPwd.text=@"";
    [prompt addSubview:txtOldPwd];
    [txtOldPwd release];

    txtNewPwd = [[UITextField alloc] initWithFrame:CGRectMake(12.0, 80.0, 260.0, 25.0)]; 
    [txtNewPwd setBackgroundColor:[UIColor whiteColor]];
    [txtNewPwd setPlaceholder:@"New Password"];
    txtNewPwd.text=@"";
    [prompt addSubview:txtNewPwd];
    [txtNewPwd release];

    txtConfirmPwd = [[UITextField alloc] initWithFrame:CGRectMake(12.0, 110.0, 260.0, 25.0)]; 
    [txtConfirmPwd setBackgroundColor:[UIColor whiteColor]];
    [txtConfirmPwd setPlaceholder:@"Confirm Password"];
    txtConfirmPwd.text=@"";
    [prompt addSubview:txtConfirmPwd];
    [txtConfirmPwd release];

    [prompt show];

    [prompt release];  

我正在添加我所获得的截图。

更新

我刚刚发现按钮实际上就在那里。警报的高度太低了。只有一小部分按钮可见。我试过this approach，但按钮仍然不可见。虽然警报的高度增加了。

                                                    delegate:self 
                                           cancelButtonTitle:nil 
                                           otherButtonTitles:@"ok", nil];

otherButtonTitles:nil];

Answer 3

hay Nitish你可以试试这段代码：

UIAlertView *alert = [[UIAlertView alloc]
                          initWithTitle:@"Reset Password"
                          message:@"\n\n" 
                          delegate:nil
                          cancelButtonTitle:@"OK"
                          otherButtonTitles:nil];

我希望它会奏效。如果需要任何澄清，请告诉我。
