我正在使用解析 SDK 向 friend 发送推送通知。 注意:我已经使用简单的 REST API 手动测试了推送通知证书，它在那里工作。

使用以下代码: 我在安装表中， channel 是数组类型，我匹配了键: 它在解析表中显示删除，但我的设备没有收到任何类型的通知(查看随附的屏幕截图)

 PFQuery * pushQuery = [PFInstallation query];
[pushQuery whereKey:@"channels" containedIn:array];
NSString * alert = [NSString stringWithFormat:@"You have a new message from %@!", [PFUser currentUser].username]; 
NSDictionary *data = [NSDictionary dictionaryWithObjectsAndKeys:
                          alert, @"alert",
                          @"default", @"sound",
                          @"Increment", @"badge",
                          nil]; [PFPush sendPushDataToQueryInBackground:pushQuery withData:data block:^(BOOL succeeded, NSError *error) {
        if (!error) {

        }
        else {
        } }];

我的委托(delegate)设置:

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {

    // Uncomment and fill in with your Parse credentials:
    [Parse setApplicationId:@“MY APP ID
                  clientKey:@“MY CLIENT KEY”];

   // Override point for customization after application launch.
[application registerForRemoteNotificationTypes:UIRemoteNotificationTypeAlert|UIRemoteNotificationTypeBadge|UIRemoteNotificationTypeSound];

}



- (void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)newDeviceToken {
    PFInstallation *currentInstallation = [PFInstallation currentInstallation];
    [currentInstallation setDeviceTokenFromData:newDeviceToken];
    currentInstallation.channels = @[@“channel”];
    [currentInstallation saveInBackground];


   }


- (void)application:(UIApplication *)application didFailToRegisterForRemoteNotificationsWithError:(NSError *)error {
    if (error.code == 3010) {
        //NSLog(@"Push notifications are not supported in the iOS Simulator.");
    } else {
        // show some alert or otherwise handle the failure to register.
        //NSLog(@"application:didFailToRegisterForRemoteNotificationsWithError: %@", error);
    }
}

- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo {
    [PFPush handlePush:userInfo];


}

//NOTE: after login i change the channels value in installation table by 

   PFInstallation *currentInstallation = [PFInstallation currentInstallation];
       // [currentInstallation setDeviceTokenFromData:newDeviceToken];

        NSString *string=[NSString stringWithFormat:@"channel%@",[PFUser currentUser]];
        NSArray *array=[NSArray arrayWithObjects:string, nil];
        currentInstallation.channels =array;
        [currentInstallation saveInBackground];

更新:使用适用于 IOS 8 的新 Parse SDK，我的问题已解决

最佳答案

如果您的设备运行 iOS 8，请注意不再支持 registerForRemoteNotificationTypes。

您需要使用registerUserNotificationSettings。下面是一个示例代码，它应该在 iOS 7(及以下)和 iOS 8 上工作:

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary*)launchOptions {

    // Checks for iOS 8
    if ([application respondsToSelector:@selector(isRegisteredForRemoteNotifications)) {

           [application registerUserNotificationSettings:[UIUserNotificationSettings settingsForTypes:(UIUserNotificationTypeSound | UIUserNotificationTypeAlert | UIUserNotificationTypeBadge) categories:nil]];

           [application registerForRemoteNotifications];

    } else {

          [application registerForRemoteNotificationTypes:
                     (UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeAlert | UIRemoteNotificationTypeSound)];

    }

    // The rest of your didFinishLaunchingWithOptions: method should be here

    return YES;
}

编辑:我刚刚看到您说它可以与 REST API 一起使用，所以这不会导致您的问题。不过，最好将您的代码更新为这样，因为您可能会遇到 iOS 8 设备的问题。

编辑 2:

问题可能来自您的 Parse 项目配置。您需要手动启用“客户端推送通知”。默认情况下，Parse 禁用它，这会阻止 Parse SDK 发送推送通知。

转到 Parse.com，转到您应用程序的设置，在“推送”部分中，然后设置“启用客户端推送？”到"is"。
