我是新來的iPhone應用程序中使用APNS。我已在所有情況下使用並接收了該消息。當user clicks the "View" button from the APNS alert i should do the actions in the app and navigate the user to 3rd tab。如何在應用程序未處於活動狀態時單擊「查看」按鈕來處理APNS消息？
但是，當應用程序在在活動（該應用程序未使用）i can't trigger the actions in the app。我在「didFinishLaunch」中使用了下面的代碼，但未使用。
NSString *params=[[launchOptions objectForKey:@"UIApplicationLaunchOptionsRemoteNotificationKey"] objectForKey:@"aps"];
NSDictionary *remoteNotif = [launchOptions objectForKey: UIApplicationLaunchOptionsRemoteNotificationKey];
NSLog(@"remoteNotif : %@", remoteNotif);
if ([params length] > 0)
{
UIAlertView *messageReceivedAlert = [[UIAlertView alloc] initWithTitle:@"My APP" message:@"New Message Recevied From APNS in IN-Active Stage" delegate:self cancelButtonTitle:nil otherButtonTitles:@"OK", nil];
[messageReceivedAlert show];
[messageReceivedAlert release];
}
它總是返回（null）。
任何人都可以幫我做到這一點嗎？提前致謝。
