通过推送通知Objective C iOS从“终止”状态打开时，应用崩溃

Question

My app working fine when app is in background and open it by clicking on Push Notification. But if I terminate app and open it through push notification then app crash. I also integrate Crashlytics. Here is attached photo & code. App crash only in one type of notification.It is not data parsing issue.

    - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    UNUserNotificationCenter *center = [UNUserNotificationCenter currentNotificationCenter];
    [center requestAuthorizationWithOptions:(UNAuthorizationOptionBadge | UNAuthorizationOptionSound | UNAuthorizationOptionAlert)
                          completionHandler:^(BOOL granted, NSError * _Nullable error) {
                              if (!error) {
                                  NSLog(@"request authorization succeeded!");
                                  //[self showAlert];
                              }
                          }];




// Branch Intigration
    Branch *branch = [Branch getInstance];

//    if is debug
//    [[Branch getInstance] setDebug];


    [branch initSessionWithLaunchOptions:launchOptions andRegisterDeepLinkHandler:^(NSDictionary *params, NSError *error) {
        if (!error && params) {
            DecisionController * mainVC = [[DecisionController alloc] init];
            [mainVC viewDidLoad];
            // params are the deep linked params associated with the link that the user clicked -> was re-directed to this app
            // params will be empty if no data found
            // ... insert custom logic here ...
            NSString * non_branch_link  = [params objectForKey:@"+clicked_branch_link"];
            if ([[params objectForKey:@"+clicked_branch_link"] boolValue]) {
                NSNotificationCenter* nc = [NSNotificationCenter defaultCenter];
                [nc postNotificationName:@"DeepLinkNotification" object:self userInfo:params];
            }
            NSLog(@"params: %@", params.description);
        }
    }];

    // MAGICAL RECORD Intigration
    [MagicalRecord setupCoreDataStackWithAutoMigratingSqliteStoreNamed:@"EmergencMeDatabase.sqlite"];
//    [Fabric with:@[[branch class]]];
    NSLog(@"magical record path to SQLite base %@", [NSPersistentStore MR_defaultLocalStoreUrl]);

问题是，您会从didFinishLaunchingWithOptions方法的launchOptions中获取打开应用程序的通知，并在打开应用程序时传递给处理该函数的相同功能，并执行push / present操作，因为尚未设置Windows的根视图控制器，导致应用程序崩溃，因此请延迟到应用激活之前
