Swift :Viewcontroller 对协议 UIGestureRecognizerDelegate 的冗余一致性

Swift : Redundant conformance of Viewcontroller to protocol UIGestureRecognizerDelegate

我想添加两个框架 SWRevealViewControllerSLKTextViewController 但是我得到了这个奇怪的错误。

我读到了这个错误,但它看起来很混乱。

Redundant conformance of Viewcontroller to protocol UIGestureRecognizerDelegate

class Viewcontroller: SLKTextViewController,SWRevealViewControllerDelegate,UIGestureRecognizerDelegate {

    // a lot of functions and code

}

错误的原因是您两次尝试符合UIGestureRecognizerDelegate。一次明确地在开头写它,第二次通过扩展已经符合它的 SLKTextViewController - the source code of SLKTextViewController 包含以下行:

NS_CLASS_AVAILABLE_IOS(7_0) @interface SLKTextViewController : UIViewController <UITextViewDelegate, UITableViewDelegate, UITableViewDataSource, UICollectionViewDelegate, UICollectionViewDataSource, UIGestureRecognizerDelegate, UIAlertViewDelegate>

其中已经列出了 UIGestureRecognizerDelegate!

的其他协议

解决方案:通过将代码更改为

删除UIGestureRecognizerDelegate
class Viewcontroller : SLKTextViewController, SWRevealViewControllerDelegate {
