ios - 通过推送通知 Objective C iOS 从 Kill 状态打开时应用程序崩溃

Question

我的应用程序在后台运行时运行良好，并通过单击推送通知打开它。但是，如果我终止应用程序并通过推送通知打开它，那么应用程序就会崩溃。我还集成了 Crashlytics。这里附上照片和代码。应用程序仅在一种类型的通知中崩溃。这不是数据解析问题。

    - (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]) {

            }
            NSLog(@"params: %@", params.description);
        }
    }];

//    [Fabric with:@[[branch class]]];
    NSLog(@"magical record path to SQLite base %@", [NSPersistentStore MR_defaultLocalStoreUrl]);

问题是您从 didFinishLaunchingWithOptions 方法的 launchOptions 获得打开应用程序的通知，并传递给打开应用程序时处理它的相同函数并执行push/present 这会使应用程序崩溃，因为尚未设置 Windows 的 Root View Controller ，因此请延迟直到应用程序处于事件状态
