我有一个应用程序，当通知被触发时，当应用程序处于后台时，我会得到一个通知栏，当我点击该栏时，它会导航到通知集的表格视图。当我从后台退出应用程序时，我收到了通知，但是当点击通知栏时，应用程序崩溃了，因为它没有获取 tableview 的索引路径。
当应用程序在后台退出并重新加载应用程序时，应进入 didfinishlaunching。
在 appDidFinishLaunching 我正在调用导航到 tableview 的方法
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
self.viewController = [[PPViewController alloc] initWithNibName:@"ViewController_iPhone" bundle:nil] ;
UILocalNotification *notification = [launchOptions objectForKey: UIApplicationLaunchOptionsLocalNotificationKey];
if (notification)
{
int remedyID = [[notification.userInfo objectForKey:kRemindMeNotificationRemedyIDKey] intValue];
NSDictionary *reminderDetails =[NSDictionary dictionaryWithObjectsAndKeys:notification.userInfo,@"kRemindMeNotificationDataKey",[NSNumber numberWithInt:remedyID],kRemindMeNotificationRemedyIDKey,nil];
[_viewController goToReminder:reminderDetails showNotification:YES];
}
[application setStatusBarStyle:UIStatusBarStyleBlackTranslucent];
self.viewController = [[PPViewController alloc] initWithNibName:@"PPViewController" bundle:nil];
self.window.rootViewController = self.viewController;
[self.window makeKeyAndVisible];
return YES;
}
**This is the code which navigates into tableview in another viewcontroller**
- (void)goToReminder:(NSMutableDictionary *)reminderDictionary showNotification:(BOOL)shouldShowNotification
{
NSIndexPath *selectedSymptIP = [NSIndexPath indexPathForRow:selectedSymptomIndex inSection:keyIndexNumber];
[self tableView:symptomsTableView didSelectRowAtIndexPath:selectedSymptIP];
}
