iOS极光推送清除角标解决方案

问题描述:
最近在项目中集成了极光推送,接收通知后,发现手机上的app图标右上角一直有个红色的数字1无法清除,但是在代码中已经设置了使角标清除的方法。

通过测试发现,如果收到通知后点击通知栏进入app,则角标会清除;
如果收到通知后直接点击app图标或者设置方法使得接收通知后直接跳转页面进入app,则角标不会清除;

解决方法如下:

//程序在运行时收到通知,点击通知栏进入app

- (void)jpushNotificationCenter:(UNUserNotificationCenter *)center willPresentNotification:(UNNotification *)notification withCompletionHandler:(void (^)(NSInteger))completionHandler {

[UIApplication sharedApplication].applicationIconBadgeNumber = 0;
[JPUSHService setBadge:0];

}

//程序在后台时收到通知,点击通知栏进入app

- (void)jpushNotificationCenter:(UNUserNotificationCenter *)center didReceiveNotificationResponse:(UNNotificationResponse *)response withCompletionHandler:(void (^)())completionHandler {

[UIApplication sharedApplication].applicationIconBadgeNumber = 0;
[JPUSHService setBadge:0];

}

//点击App图标,使App从后台恢复至前台
- (void)applicationWillEnterForeground:(UIApplication *)application {
[application setApplicationIconBadgeNumber:0];
[application cancelAllLocalNotifications];
}



//按Home键使App进入后台

- (void)applicationDidEnterBackground:(UIApplication *)application{
[application setApplicationIconBadgeNumber:0];
[application cancelAllLocalNotifications];
}

注意:
(1) [UIApplication sharedApplication].applicationIconBadgeNumber = 0;

(2) [JPUSHService setBadge:0];/[application cancelAllLocalNotifications];//清除所有通知

这两个方法要同时使用才能清除本地图标和远程的通知!
