推送通知后运行功能

问题描述：

我正在为iPad开发iOS应用程序。我正在使用名为HelpShift的服务使用推送通知。我想在用户点击通知时运行一段代码。它实际上在应用程序处于活动状态时起作用，但当它处于后台或不活动状态时，它不起作用。这里是我的代码：推送通知后运行功能

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

if ([[userInfo objectForKey:@"origin"] isEqualToString:@"helpshift"]) { 

    UIApplicationState state = [application applicationState]; 

    if (state == UIApplicationStateActive) {   

     UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"You were answered in HelpShift" 
                  message:@"Hello" 
                  delegate:self 
                cancelButtonTitle:@"Cancel" 
                otherButtonTitles:@"Show", nil]; 
     [alertView show]; 

    } if (state== UIApplicationStateBackground) { 

     UIViewController *vc = self.window.rootViewController; 
     [[Helpshift sharedInstance] handleNotification:userInfo withController:vc];    

     [self showHelpShift]; 

    } if (state == UIApplicationStateInactive) { 

     UIViewController *viewController = 
     [[UIStoryboard storyboardWithName:@"MainStoryboard" 
            bundle:NULL] instantiateViewControllerWithIdentifier:@"home"]; 

     [[Helpshift sharedInstance] handleNotification:userInfo withController:viewController]; 


    }   
    } 
} 


- (void) showHelpShift { 
    UIViewController *vc = self.window.rootViewController; 
    [[Helpshift sharedInstance] showSupport:vc]; 
    } 

- (void)alertView:(UIAlertView *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex{ 

    if (buttonIndex == 1){ 
    UIViewController *vc = self.window.rootViewController; 
    [[Helpshift sharedInstance] showSupport:vc];} 
}

因此，大家可以看到，问题是[自showHelpShift]不会被调用或者被调用提前。

通知发送到传递给vapplicationDidLaunch消息的字典中。上述消息不在发布时发送。 – 2013-03-24 12:28:45

那么？我有什么编码？ – 2013-03-24 12:37:09

所以你实现了推送通知，但从来没有读过Apple的优秀指南呢？打开“本地通知和推送通知”指南并阅读“处理本地和远程通知”部分。 – 2013-03-25 12:11:13

答

执行application:didFinishLaunchingWithOptions:并在launchOptions字典中查找UIApplicationLaunchOptionsRemoteNotificationKey键。

我不知道你的意思。我试过UIApplicationLaunchOptionsRemoteNotificationKey，但应用程序崩溃... – 2013-03-24 13:12:04
