我正在創建一個聊天應用程序，用戶首先進入主菜單，在那裏他們可以選擇「聊天」，然後定向到FB登錄功能，用戶登錄後FB，他們應該被重定向到一個標籤欄控制器。但是我無法弄清楚如何設置程序繼續，以便在成功登錄後直接將用戶帶到該屏幕。連接解析與FB集成
我不知道這是爲什麼Parse沒有收集用戶數據，但我在運行應用程序時得到這個警告：[10799：60b]警告：長時間運行的Parse操作正在執行主線程。打破warnParseOperationOnMainThread（）進行調試。我的問題是我如何創建segue到我的標籤欄控制器，我缺少一些解析？
這裏是我的AppDelegate.m文件：
#import "CCAppDelegate.h"
#import <Parse/Parse.h>
@implementation CCAppDelegate
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
// Override point for customization after application launch.
[Parse setApplicationId:@"XXXX"
clientKey:@"XXXX"];
[PFAnalytics trackAppOpenedWithLaunchOptions:launchOptions];
[PFFacebookUtils initializeFacebook];
[FBLoginView class];
[FBProfilePictureView class];
return YES;
}
- (BOOL)application:(UIApplication *)application openURL:(NSURL *)url sourceApplication:(NSString *)sourceApplication annotation:(id)annotation
{
BOOL wasHandled = [FBAppCall handleOpenURL:url sourceApplication:sourceApplication];
return wasHandled;
}
- (void)applicationWillResignActive:(UIApplication *)application
{
// Sent when the application is about to move from active to inactive state. This can occur for certain types of temporary interruptions (such as an incoming phone call or SMS message) or when the user quits the application and it begins the transition to the background state.
// Use this method to pause ongoing tasks, disable timers, and throttle down OpenGL ES frame rates. Games should use this method to pause the game.
}
- (void)applicationDidEnterBackground:(UIApplication *)application
{
// Use this method to release shared resources, save user data, invalidate timers, and store enough application state information to restore your application to its current state in case it is terminated later.
// If your application supports background execution, this method is called instead of applicationWillTerminate: when the user quits.
}
- (void)applicationWillEnterForeground:(UIApplication *)application
{
// Called as part of the transition from the background to the inactive state; here you can undo many of the changes made on entering the background.
}
- (void)applicationDidBecomeActive:(UIApplication *)application
{
// Restart any tasks that were paused (or not yet started) while the application was inactive. If the application was previously in the background, optionally refresh the user interface.
}
- (void)applicationWillTerminate:(UIApplication *)application
{
// Called when the application is about to terminate. Save data if appropriate. See also applicationDidEnterBackground:.
}
