如何将收到的通知信息放入应用中的UITableView中？

Question

我正在尝试在我的应用程序上实施 Apple 推送通知服务。我关注了 Pushbots tutorial 但是否可以从通知中获取信息并将其放入 table?

我添加到项目中的唯一代码在 AppDelegate.m 文件中。

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    [Pushbots sharedInstanceWithAppId:@"--my app id--"];
    [[Pushbots sharedInstance] receivedPush:launchOptions];
    return YES;
}

- (void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken {
    // This method will be called everytime you open the app
    // Register the deviceToken on Pushbots
    [[Pushbots sharedInstance] registerOnPushbots:deviceToken];
}
-(void)application:(UIApplication *)application didFailToRegisterForRemoteNotificationsWithError:(NSError *)error{
    NSLog(@"Notification Registration Error %@", [error userInfo]);
}

- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo {
    //Handle notification when the user click it while app is running in background or foreground.
    [[Pushbots sharedInstance] receivedPush:userInfo];
}

Answer 1

每当收到通知时，didReceiveRemoteNotification 将使用负载（即用户信息）调用。您可以使用解析负载并将其显示到 table 视图

Answer 2

请将以下代码添加到您的项目中。

-(void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo
{
[[NSUserDefaults standardUserDefaults] setObject:[[userInfo objectForKey:@"aps"] objectForKey: @"id"]  forKey:@"pushstring"];
[[NSUserDefaults standardUserDefaults]synchronize];
[[NSNotificationCenter defaultCenter] postNotificationName:@"pushNotification" object:nil userInfo:userInfo];
[UIApplication sharedApplication].applicationIconBadgeNumber = [[[userInfo objectForKey:@"aps"] objectForKey: @"badgecount"] intValue];

NSLog(@"value of array is %@",userInfo);
//NSMutableArray *arr=[[NSMutableArray alloc]init];

// [arr addObject:[[userInfo valueForKey:@"aps"]valueForKey:@"category"]];
NSLog(@"value of array is %d",[[[userInfo objectForKey:@"aps"] objectForKey: @"badgecount"] intValue]);
//    for (arr in userInfo) {
//        NSLog(@"key: %@, value: %@", arr, [userInfo objectForKey:arr]);
//    }
//    NSLog(@"value of alert is %@",[arr objectAtIndex:2]);
//  NSLog(@"value of category is %@",[[arr objectAtIndex:0]objectAtIndex:2]);

}

希望对您有所帮助。

是的，当在 didReceiveRemoteNotification 方法中收到通知时，您将从 userinfo 获取有效负载，以便您可以使用数据修改 table。

Answer 4

userInfo 是包含推送通知的字典。 aps 是推送通知正文的键。

将负载保存在 NSUserDefaults 中，稍后在 ViewController 中使用它来填充 tableView。

    -(void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo
  {
                // you can get the required message as below
                NSString *msg = [userInfo valueForKey:@"aps"];
                NSLog(@"Push Notification:%@",msg);

                [[NSUserDefaults standardUserDefaults]setObject:msg forKey:@"ReceivedNotifications"];
                //This is how you save object in NSUserDefaults
  }

现在在你的 ViewController.m

{
NSMutableArray *notificationArray= [NSMutableArray alloc]init];
notificationArray= [[NSUserDefaults standardUserDefaults]objectForKey:@"ReceivedNotifications"];
}

使用此 notificationArray 加载您的 tableView。
