Question

我正在尝试很多但尚未成功在应用程序被杀死状态时获得无声通知

这是我正在尝试的代码..

APS数据：

Failed to resolve: android.arch.lifecycle:extensions:1.0.0-alpha1

Answer 1

在有效负载的aps词典中，不得包含提醒，声音或徽章键。

{
    "aps":{
        "content-available" : 1
    }
}

请试一试。

Answer 2

您应该在AppDelegate.m

中实施

-(void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo fetchCompletionHandler:(void (^)(UIBackgroundFetchResult))completionHandler{
    NSDictionary *aps = [userInfo objectForKey:@"aps"];
    NSLog(@"hello");
    NSLog(@"userinfo---->>>>%@",userInfo);
    [UIApplication sharedApplication].applicationIconBadgeNumber=[[aps objectForKey:@"badge"] integerValue];
    [self application:application didReceiveRemoteNotification:userInfo];
}
