大佬教程收集整理的这篇文章主要介绍了ios – ‘userNotificationCenter：didReceiveNotificationResponse’实现中的冲突参数类型，大佬教程大佬觉得挺不错的，现在分享给大家，也给大家做个参考。
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;
- (void)userNotificationCenter:(UNUserNotificationCenter *)center
didReceiveNotificationResponse:(UNNotificationResponse *)response
withCompletionHandler:(void (^)(void))completionHandler;
现在警告消失了.
