用于远程和本地通知的 iOS 徽章

Question

我的应用接收推送和本地两种类型的通知，我不知道管理徽章编号的最佳方式是什么。在本地通知的情况下，每当我创建一个时，我都会增加徽章计数器，但在推送通知的情况下......如果我没记错的话，只有当用户通过点击启动应用程序时才会调用委托方法 didReceiveRemoteNotification:警报或横幅，或者应用程序是否处于活动状态。否则，徽章的值是从通知的有效负载中获取的，不是吗？那么......考虑到收到的本地通知 + 远程通知，我怎么能始终获得更新的徽章值？

谢谢

您在远程通知中得到如下响应。

Connection OK sending message :{"aps":{"alert":"pushnotification testing","content-available":"","badge":"1","sound":"default"}} 134

在 AppDelegte.h 类中

取一个整数变量int i=0;

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    application.applicationIconBadgeNumber = 0;

    UILocalNotification *localNoty=[launchOptions objectForKey:UIApplicationLaunchOptionsLocalNotificationKey];

    if (localNoty) {
        NSLog(@"Recieved Notification %@",localNoty);
    }

    return YES;
}

//收到通知

- (void)application:(UIApplication *)app didReceiveLocalNotification:(UILocalNotification *)notif {
    // Handle the notificaton when the app is running

    app.applicationIconBadgeNumber=i++;
    NSLog(@"Recieved Notification %@",notif);
}

- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo {

#if !TARGET_IPHONE_SIMULATOR
    NSString *badge = [apsInfo objectForKey:@"badge"];
    NSLog(@"Received Push Badge: %@", badge);

    // set it to Zero will clear it.
    [[UIApplication sharedApplication] setApplicationIconBadgeNumber:0];

#endif
}

-(void) pw_setApplicationIconBadgeNumber:(NSInteger) badgeNumber
{
    [UIApplication sharedApplication].applicationIconBadgeNumber +=badgeNumber;
}

// 当应用激活时将徽章设置为零。

- (void)applicationDidBecomeActive:(UIApplication *)application
{
    // Restart any tasks that were paused (or not yet started) while the application was inactive. If the application was previously in the background, optionally refresh the user interface.

    application.applicationIconBadgeNumber =nil;

}
