iphone - 使用 UILongPressGestureRecognizer 和 UIBarButtonItem

Question

<分区>

Answer 1

在 UIBarButtonItem 项中添加 subview 手势是一个痛苦的过程。我在下面的代码中向您展示。它可能对你有帮助。

I like to suggest you that instead of groping around for a subview you can create the button on your own and add a button bar item with a custom view

[[[yourToolbar subviews] objectAtIndex:[[yourToolbar items] indexOfObject:yourBarButton]] addGestureRecognizer:YourGesture];

//或者您也可以尝试以下....

[self.barButtonItem.customView addGestureRecognizer:longProcess];// i didn't declare longProcess and singletap GestureRecognizer here. I hope you can do that.
[self.barButtonItem.customView addGestureRecognizer:singletap];

希望这对你有帮助..
