ios - 不是为 LocalNotification 调用的后台方法

Question

如果我从后台强行关闭我的应用程序。然后本地通知来了。如果点击本地通知，当应用程序在前台运行时我的方法不会被调用。我在 iOS 中较新。请帮忙。

-(void)application:(UIApplication *)application handleActionWithIdentifier:(NSString *)identifier forLocalNotification:(UILocalNotification *)notification completionHandler:(void (^)())completionHandler
{
    [[NSNotificationCenter defaultCenter] postNotificationName:@"Reh" object:nil];

    [[UIApplication sharedApplication] setApplicationIconBadgeNumber: 0];
    [[UIApplication sharedApplication] cancelAllLocalNotifications];
    UIApplicationState state = [application applicationState];

    if (state == UIApplicationStateActive) {

        UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Reminder"

                                                        message:notification.alertBody

                                                       delegate:self cancelButtonTitle:@"OK"

                                              otherButtonTitles:nil,nil];





        [alert show];


        NSLog(@"%@",notification.soundName);






        // AudioServicesPlaySystemSound (1010);




        MyNotificationViewController *profile=[[MyNotificationViewController alloc]initWithNibName:@"MyNotificationViewController" bundle:nil];
        [[NSNotificationCenter defaultCenter] postNotificationName:@"RefreshFoeByPush" object:nil];

        self.viewController = [[SWRevealViewController alloc] initWithRearViewController:self.leftMenuController frontViewController:profile];        self.viewController.rightViewController=nil;
        [UIView transitionWithView:self.window duration:0.5 options:UIViewAnimationOptionCurveEaseInOut
                        animations:^{self.window.rootViewController = self.viewController;} completion:nil];






        application.applicationIconBadgeNumber = 0;

    }
    else

    {
        NSString *tokend=     [[NSUserDefaults standardUserDefaults] stringForKey:@"token"];
        if (tokend == (id)[NSNull null] || tokend.length == 0 )
        {

        }
        else
        {
            MyNotificationViewController *profile=[[MyNotificationViewController alloc]initWithNibName:@"MyNotificationViewController" bundle:nil];
            [[NSNotificationCenter defaultCenter] postNotificationName:@"RefreshFoeByPush" object:nil];

            self.viewController = [[SWRevealViewController alloc] initWithRearViewController:self.leftMenuController frontViewController:profile];        self.viewController.rightViewController=nil;
            [UIView transitionWithView:self.window duration:0.5 options:UIViewAnimationOptionCurveEaseInOut
                            animations:^{self.window.rootViewController = self.viewController;} completion:nil];


        }
    }

}

Answer 1

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

    UILocalNotification *localNotification = [launchOptions objectForKey:UIApplicationLaunchOptionsLocalNotificationKey];
    if (localNotification != nil) {
        [self showLocalNotificationAlert:localNotification];
    }

    return YES;
}


- (void)application:(UIApplication *)application didReceiveLocalNotification:(UILocalNotification *)notification
{    
    [self showLocalNotificationAlert:notification];
}


-(void)showLocalNotificationAlert:(UILocalNotification *)notification {
    // handle here what you want
}

还有

当本地通知触发 didReceiveLocalNotification 方法时调用不是 handleActionWithIdentifier

是的，把你的东西放在通用方法中 -(void)showLocalNotificationAlert:(UILocalNotification *)notification 所以你只需要调用

1. 当应用程序在前台时，didReceiveLocalNotification 将被调用。

2. 当应用程序不在前台并且您点击通知时，可以从 didFinishLaunchingWithOptions

获取此通知对象

用于远程通知

在 didFinishLaunchingWithOptions 中

NSDictionary *remoteNotification = [launchOptions objectForKey:UIApplicationLaunchOptionsRemoteNotificationKey];
    if (remoteNotification) {
        [self showRemoteNotificationAlert:remoteNotification];
    }

Dictionary contains payload for remotenotification

并且还制作了远程通知fire和远程通知taped的通用方法。

哈哈
