swift - iOS ActionSheet Delegate 冲突的问题

Question

在我的App中有很多地方用到了ActionSheet,最近发布了一个版本,由于测试忘记测相机了,导致上线后发现一个bug,相机的ActionSheet占据了第一和第一的位置,结果当别的地方点击actionsheet前两个的时候都会跳转到相机或者是相册,请问大家怎么解决这个问题呢?

Answer 1

The

delegate function has the parameter actionSheet itself.

- (void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex;

can be used to determine which actionSheet it is.

As for how to distinguish, you can add a tag when creating the actionSheet; secondly, you can also save the actionSheet and determine if (actionSheet == self.actionSheet1) like this in the delegate function. However, actionSheet may retain the delegate. It is better to use weak references when saving...

Answer 2

You can use Block to write a synchronous ActionSheet, and the code looks intuitive.
