编辑很抱歉误解了您的问题。链接页面中显示的警报视图非常容易重现。以下是我提出的建议：

EDIT Sorry for misunderstanding your problem. The alert view shown in the linked page is extremely easy to reproduce. Here's what I came up with:

为方便起见，我用类别实现了这一点，但您可以轻松地在其他地方实现它。基本上你要做的是添加一个取消按钮，然后隐藏它。这样，就警报视图而言，有三个按钮，它不会并排放置两个可见按钮。类别实现如下：

I implemented this with a category for convenience but you could easily just implement it elsewhere. Basically what you do is add a cancel button and then hide it. That way there are three buttons as far as the alert view is concerned and it does not place the two visible buttons side by side. The category implementation is as follows:

-(void)showWithCutCancelButton{
    // Make sure alert view will look right
    if (self.cancelButtonIndex == -1 || self.numberOfButtons < 3) return;
    self.clipsToBounds = YES; // or else cancel button will still be visible
    [self show];
    // Shrink height to leave cancel button outside
    self.bounds = CGRectMake(0, 0, self.bounds.size.width, self.bounds.size.height - 64);
}

然后通过致电显示：

UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Hello" message:@"Message here" delegate:self cancelButtonTitle:@"Cancel" otherButtonTitles:@"Option1", @"Option2", nil];
[alert showWithCutCancelButton];
