ios – ‘userNotificationCenter：didReceiveNotificationResponse’实现中的冲突参数类型

2019年7月28日 415次阅读

此错误刚刚开始弹出.是bug还是更新？

Conflicting parameter types in implementation of 'userNotificationCenter:didReceiveNotificationResponse:withCompletionHandler:': 'void (^ _Nonnull __strong)(void)' vs 'void (^__strong _Nonnull)()'

我的守则

// Handle notification messages after display notification is tapped by the user.
- (void)userNotificationCenter:(UNUserNotificationCenter *)center
didReceiveNotificationResponse:(UNNotificationResponse *)response withCompletionHandler:(void (^)())completionHandler {

先前的定义(他们的代码)

// The method will be called on the delegate when the user responded to the notification by opening the application, dismissing the notification or choosing a UNNotificationAction. The delegate must be set before the application returns from application:didFinishLaunchingWithOptions:.
- (void)userNotificationCenter:(UNUserNotificationCenter *)center didReceiveNotificationResponse:(UNNotificationResponse *)response withCompletionHandler:(void(^)(void))completionHandler __IOS_AVAILABLE(10.0) __WATCHOS_AVAILABLE(3.0) __TVOS_PROHIBITED;

最佳答案 我有同样的问题.我改成了：

- (void)userNotificationCenter:(UNUserNotificationCenter *)center 
didReceiveNotificationResponse:(UNNotificationResponse *)response 
         withCompletionHandler:(void (^)(void))completionHandler;

现在警告消失了.
