iPhone SDK中前臺的本地通知

Question

當應用處於前臺並且當前在iPhone SDK中運行時，本地通知是否會顯示？

Answer 1

不，您將收到appdelegate中的通知。

- (void) application:(UIApplication *)application didReceiveLocalNotification: (UILocalNotification *)notification { 
    //Place your code to handle the notification here. 
} 

Answer 2

如果您的應用程序是目前在前臺下面的函數將被調用你的委託：

- (void)application:(UIApplication *)application didReceiveLocalNotification:(UILocalNotification *)Notifikation 

然後你可以決定顯示的alertview，但其本身的標準一個不會出現

Answer 3

我做了一個lib，使動畫幾乎與本地通知一樣。

檢查： https://github.com/OpenFibers/OTNotification

演示：

而當你在

- (void) application:(UIApplication *)application didReceiveLocalNotification: (UILocalNotification *)notification 
{ 
    OTNotificationManager *notificationManager = [OTNotificationManager defaultManager]; 
    OTNotificationMessage *notificationMessage = [[OTNotificationMessage alloc] init]; 
    notificationMessage.title = [self notificationTitle]; 
    notificationMessage.message = @"A notification. Touch me to hide me."; 
    [notificationManager postNotificationMessage:notificationMessage]; 
} 

Answer 4

接收到的消息可以發佈一個新的消息，這LIB接受的anser是正確的，但它不夠○接收所有通知，並顯示一些用戶從

- (void) application:(UIApplication *)application didReceiveLocalNotification: (UILocalNotification *)notification { 

你必須檢查，是當前的通知與否。 有時會發生另一個通知（例如，當您取消它們時）。所以，你必須檢查，那是你除了：

- (void)application:(UIApplication *)application didReceiveLocalNotification:(UILocalNotification *)notification { 
    if (fabs([[NSDate date] timeIntervalSinceDate:[notification fireDate]]) <= 0.5f) 
    { 
     [[[UIAlertView alloc] initWithTitle:NSLocalizedString(@"Notification alert", @"") 
            message:notification.alertBody 
            delegate:self 
          cancelButtonTitle:@"Ok" otherButtonTitles:nil] show];  
    } 
}

雨燕2.2：

func application(application: UIApplication, didReceiveLocalNotification notification: UILocalNotification) { 
    var state = application.applicationState 
    if state == .Active { 
     // handle the notification, e.g. show an alert 
    } 
} 

雨燕3.0：

func application(_ application: UIApplication, didReceive notification: UILocalNotification) { 
    var state: UIApplicationState = application.applicationState 
    if state == .active { 
     // handle the notification, e.g. show an alert 
    } 
}
