iphone - 以编程方式取消 UIAlertView

Question

如何以编程方式取消 UIAlertView？ 这是我用来显示 UIAlertView 的代码

UIAlertView *myAlertView = [[UIAlertView alloc] initWithTitle:@"Save Background" message:@"Downloading..." delegate:self cancelButtonTitle:@"Cancel" otherButtonTitles:nil, nil];
    CGAffineTransform myTransform = CGAffineTransformMakeTranslation(0.0, 70.0);
    [myAlertView setTransform:myTransform];
    [myAlertView show];

尝试像这样使用 dismissWithClickedButtonIndex::

这里是要使用的代码:

[myAlertView dismissWithClickedButtonIndex:-1 animated:YES];
