通过通知启动应用程序崩溃

Question

在我的远程通知实现中，我这样做了

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

if (launchOptions) {
    NSDictionary* userInfo = [launchOptions objectForKey:UIApplicationLaunchOptionsRemoteNotificationKey];
    NSDictionary *dictionary=[userInfo objectForKey:@"jsonContent"];
    dm.notificationDictionary=nil;
    dm.notificationDictionary=dictionary;
    NSDictionary *aps=[userInfo objectForKey:@"aps"];
    dm.badgeNumber=[[aps valueForKey:@"badge"] intValue];
}



viewController1 = [[SplashViewController alloc] initWithNibName:@"SplashViewController" bundle:nil];


UINavigationController *aNavigationController=[[UINavigationController alloc] initWithRootViewController:viewController1];

self.navigationcontroller = aNavigationController ;
self.navigationcontroller.navigationBar.hidden=YES;


[self.window setRootViewController:self.navigationcontroller];
[self.window makeKeyAndVisible];

return YES;

}

然后

- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo fetchCompletionHandler:(void (^)(UIBackgroundFetchResult))completionHandler
{
      dm=[DataManager sharedManager];
     ws=[[WebService alloc] init];
     NSLog(@"%@",userInfo);
     dm.isFroTabNotify=NO;
     NSDictionary *dictionary=[userInfo objectForKey:@"jsonContent"];
     dm.notificationDictionary=nil;
     dm.notificationDictionary=dictionary;
     NSDictionary *aps=[userInfo objectForKey:@"aps"];
     dm.badgeNumber=[[aps valueForKey:@"badge"] intValue];
     arrayHeader=[ws GetNotificationHeaders];//--------To get unread notification count


   [[NSNotificationCenter defaultCenter] postNotificationName:@"MyPersonalNotification" object:[aps valueForKey:@"badge"]];


  if (application.applicationState==UIApplicationStateActive) {




    [AGPushNoteView showWithNotificationMessage:[dm.notificationDictionary valueForKey:@"message"]];

    if([[dm.notificationDictionary valueForKey:@"type"] intValue]==12)
    {
        dm=[DataManager sharedManager];

    }

当应用程序处于后台和前台时，它可以正常工作。但是当应用程序没有运行时，当我点击通知启动应用程序时它会崩溃。这是什么原因，我该如何解决这个问题？请帮我。 感谢

Answer 1

正如我在方法中看到的那样 - application:didReceiveRemoteNotification:fetchCompletionHandler: 您已编码两个状态UIApplicationStates活动状态和所有其他状态（在else块中），这可能是用户杀死（强制退出）应用程序并且远程通知到达并且- application:didReceiveRemoteNotification:fetchCompletionHandler:方法为当用户点击通知警报时调用。

根据苹果文档，

  

注意：如果用户从系统显示的警报中打开您的应用程序，则   当您的应用即将进入时，系统可能会再次调用此方法   前景，以便您可以更新您的用户界面和显示   有关通知的信息。

所以，认为你应该查看代码，必须对任何导致错误的代码块进行双重调用，特别是在初始化UIViewController对象或UINavigationController对象的地方。
