iphone - 更改 UIActionSheet 的 UIAlertButton 的字体

Question

如何访问UIAlertView按钮的titleLabel属性？我试过以下代码：

for (UIView *view in  action.subviews)
    {
        if([view isKindOfClass:[NSClassFromString(@"UIAlertButton") class]])
        {
            //Do something with title label font
        }
    }

像这样尝试，您可以根据您的要求更改 view.tag

 - (void)willPresentAlertView:(UIAlertView *)alertView{
       for(UIView *view in alertView.subviews)
        if(([view isKindOfClass:[UIButton class]]) && (view.tag ==1)){
            UIButton *btn = (UIButton *)view;
            btn.titleLabel.text=@"your title";

        }
}
