アプリケーションが既に実行されている場合、プッシュ通知を処理するにはどうすればよいですか？

アプリケーションがすでに実行されている場合、プッシュ通知をどのように処理しますか？ （プッシュ通知アラートの代わりに）アプリケーションが実行されている場合にアラートを表示したい。アプリケーションが実行されていない場合のみ、プッシュ通知アラートを表示します。

また、ペイロードをAPNに送信する場合、キャンセルボタンでアラートを作成するにはどうすればよいですか？

application:didReceiveRemoteNotification:

これが可能なサンプルコードです：

- (void)application:(UIApplication *)application
   didReceiveRemoteNotification:(NSDictionary *)userInfo
{
  NSString *message = nil;
  id alert = [userInfo objectForKey:@"alert"];
  if ([alert isKindOfClass:[NSString class]]) {
    message = alert;
  } else if ([alert isKindOfClass:[NSDictionary class]]) {
    message = [alert objectForKey:@"body"];
  }
  if (alert) {
    UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"Title"
                                       message:@"AThe message."  delegate:self
                             cancelButtonTitle:@"button 1"
                             otherButtonTitles:@"button", nil];
    [alertView show];
    [alertView release];
  }

UIApplicationの状態を確認できます。このようにチェックするだけです

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

    UIApplicationState state = [application applicationState];
    if (state == UIApplicationStateActive)
    {

            UIAlertView *alert = [[[UIAlertView alloc] initWithTitle:@"xxx" message:yourMessage delegate:self cancelButtonTitle:@"Done" otherButtonTitles: @"Anzeigen", nil] autorelease];
            [alert setTag: 2];
            [alert show];
    }
    else {
        // Push Notification received in the background
    }
}

「alert」キーはuserInfoディクショナリの直下にはありません。「aps」という名前の別のディクショナリを取得してから、「aps」ディクショナリから「alert」または「body」を取得する必要があります。

ペイロードの3つのレベルの反復

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

for (id key in userInfo) {
    NSLog(@"key: %@, value: %@", key, [userInfo objectForKey:key]);
    NSString *message = nil;

NSDictionary *aps = [NSDictionary dictionaryWithDictionary:(NSDictionary *) [userInfo objectForKey:key] ];   
    for (id key1 in aps){
         NSLog(@"key1: %@", key1);
        id alert = [aps objectForKey:key1];
        if ([alert isKindOfClass:[NSDictionary class]]) {
            message = [alert objectForKey:@"body"];
             NSLog(@"body: %@, value: %@", key1, message);
            message = [alert objectForKey:@"loc-args"];
            NSLog(@"loc-args: %@, value: %@", key1, message);
            NSArray *args = (NSArray *) [alert objectForKey:@"loc-args"] ;
                for (id key2 in args){
                    NSLog(@"key2: %@, value: ", key2);
                }
            message = [alert objectForKey:@"action-loc-key"];
            NSLog(@"action-loc-key: %@, value: %@", key1, message);

        }
        else if ([alert isKindOfClass:[NSArray class]]) {
            for (id key2 in key1){
                NSLog(@"key2: %@, value: %@", key2, [key1 objectForKey:key2]);
            }
        }
        else if([key1 isKindOfClass:[NSString class]]) {
            message = [aps objectForKey:key1];
            NSLog(@"key1: %@, value: %@", key1, message);
        } 

    }
  }

}

結果は次のとおりです。
