Question

我正在创建一个聊天应用，用户首先被带到主菜单，在那里他们可以选择聊天＆＃34;然后转到FB登录功能，用户使用FB登录后，应该将它们重定向到标签栏控制器。但是，我无法弄清楚如何设置程序设置，以便在成功登录后将用户直接带到该屏幕。

我不知道这是不是Parse没有收集用户数据的原因，但我在运行应用程序时收到此警告：[10799：60b]警告：正在主线程上执行正在运行的Parse操作。打破warnParseOperationOnMainThread（）进行调试。我的问题是我如何创建segue到我的Tab Bar Controller并且我错过了Parse的东西？

以下是我的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:.
}

这是我的CCLoginViewController.m文件：

#import "CCLoginViewController.h"

@interface CCLoginViewController ()

@property (strong, nonatomic) IBOutlet UIActivityIndicatorView *activityIndicator;

@end

@implementation CCLoginViewController

-(void)toggleHiddenState:(BOOL)shouldHide
{
    self.lblUsername.hidden = shouldHide;
    self.lblEmail.hidden = shouldHide;
    self.profilePictureView.hidden = shouldHide;
}

-(void)loginViewShowingLoggedInUser:(FBLoginView *)loginView{
    self.lblLoginStatus.text = @"You are logged in.";

    [self toggleHiddenState:NO];
}
-(void)loginViewFetchedUserInfo:(FBLoginView *)loginView user:(id<FBGraphUser>)user{
    NSLog(@"%@", user);
    self.profilePictureView.profileID = user.objectID;
    self.lblUsername.text = user.name;
    self.lblEmail.text = [user objectForKey:@"email"];
}
-(void)loginViewShowingLoggedOutUser:(FBLoginView *)loginView{
    self.lblLoginStatus.text = @"You are logged out";

    [self toggleHiddenState:YES];
}
-(void)loginView:(FBLoginView *)loginView handleError:(NSError *)error{
    NSLog(@"%@", [error localizedDescription]);
}

- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
    self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
    if (self) {
        // Custom initialization
    }
    return self;
}

- (void)viewDidLoad
{
    self.loginView.delegate = self;

    [super viewDidLoad];
    // Do any additional setup after loading the view.
    [self toggleHiddenState:YES];
    self.lblLoginStatus.text = @"";
    self.lblLoginStatus.text = @"";
    self.loginView.readPermissions = @[@"public_profile", @"email"];
}

- (void)didReceiveMemoryWarning
{
    [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.
}

/*
#pragma mark - Navigation

// In a storyboard-based application, you will often want to do a little preparation before navigation
- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
    // Get the new view controller using [segue destinationViewController].
    // Pass the selected object to the new view controller.
}

根据iOS, Facebook Users上的文档，您应该稍微改变一下FBAppCall：

- (BOOL)application:(UIApplication *)application 
            openURL:(NSURL *)url
  sourceApplication:(NSString *)sourceApplication
         annotation:(id)annotation {
    return [FBAppCall handleOpenURL:url
                  sourceApplication:sourceApplication
                        withSession:[PFFacebookUtils session]];
}

- (void)applicationDidBecomeActive:(UIApplication *)application {
    [FBAppCall handleDidBecomeActiveWithSession:[PFFacebookUtils session]];
}

您遗失的关键部分是withSession:[PFFacebookUtils session]，我猜测Parse可以了解Facebook正在做什么。

我也没有在您的代码中看到任何Parse查询，因此代码的其他部分必须触发该警告，在某个地方您不使用withBlock:进行查询让它在后台线程上处理结果而不会锁定UI。

使用FB集成连接Parse
