ios - 使用私有(private) API 自定义 UIActionSheet

Question

我需要在操作表按钮上添加图像，所以我使用了以下代码

UIActionSheet *actionSheetObject = [[UIActionSheet alloc] initWithTitle:@"Follow Us" delegate:self cancelButtonTitle:kCancel destructiveButtonTitle:nil otherButtonTitles:@"Twitter",@"Facebook",@"Blog",@"LinkedIn",nil];
[[[actionSheetObject valueForKey:@"_buttons"] objectAtIndex:0] setImage:[UIImage imageFromBundle:@"TwitterIcon"] forState:UIControlStateNormal];
[[[actionSheetObject valueForKey:@"_buttons"] objectAtIndex:1] setImage:[UIImage imageFromBundle:@"FacebookIcon"] forState:UIControlStateNormal];
[[[actionSheetObject valueForKey:@"_buttons"] objectAtIndex:2] setImage:[UIImage imageFromBundle:@"BlogIcon"] forState:UIControlStateNormal];
[[[actionSheetObject valueForKey:@"_buttons"] objectAtIndex:3] setImage:[UIImage imageFromBundle:@"LinkedInIcon"] forState:UIControlStateNormal];
[actionSheetObject showInView:self.view];

输出

但我的问题是实现这一目标的正确方法吗？意味着Apple会在appstore上接受我的应用程序吗？

Answer 1

如果您想将您的应用放在 AppStore 上，请不要使用私有(private) API。 Apple 将拒绝使用私有(private) API 的应用。

根据 UIActionSheet Documentation :

UIActionSheet is not designed to be subclassed, nor should you add views to its hierarchy. If you need to present a sheet with more customization than provided by the UIActionSheet API, you can create your own and present it modally with presentViewController:animated:completion:.

作为替代方法，您可以将自定义的 UIView 与这些 UIButtons 一起使用。当它显示时，你可以禁用父 View 的触摸事件，这样它就和action-sheet一样。

这是一个例子:Display a custom UIView like a UIActionSheet
