    清除手机APP应用图标右上角的红色角标:

    1.在你想要清除的地方执行以下代码

        if (@available(iOS 16.0, *)) {
            [[UNUserNotificationCenter currentNotificationCenter] setBadgeCount:0 withCompletionHandler:nil];
        }else {
            [[UIApplication sharedApplication] setApplicationIconBadgeNumber:0];
        }
    

    2.在AppDelegate代理方法中执行以下代码(例如:- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary<UIApplicationLaunchOptionsKey,id> *)launchOptions{})

      if (@available(iOS 16.0, *)) {
            [[UNUserNotificationCenter currentNotificationCenter] setBadgeCount:0 withCompletionHandler:nil];
        }else {
            [application setApplicationIconBadgeNumber:0];
        }
    

    API说明:

    1.UNUserNotificationCenter实例方法只有16.0及以上系统版本可用

    - (void)setBadgeCount:(NSInteger)newBadgeCount withCompletionHandler:(nullable void(^)(NSError *__nullable error))completionHandler API_AVAILABLE(macos(13.0), ios(16.0), tvos(16.0)) API_UNAVAILABLE(watchos);

    2.setter属性变量自17.0系统版本开始废弃

    @property(nonatomic) NSInteger applicationIconBadgeNumber API_DEPRECATED("Use -[UNUserNotificationCenter setBadgeCount:withCompletionHandler:] instead.", ios(2.0, 17.0));
