Facebook api ios-sdk，代表不工作，fbDidLogin没有调用

Question

I have a problem with the latest iOS sdk. I successfully login and the application comes back but the delegation methods like fbDidLogin etc do not get called.

If tried it all in just one delegate file without any controllers and got it working. But if I have several controllers it's not working anymore/

I use my self written class FacebookFetchter to deal with Facebook.

    //FacebookFetchter.h
    #import Foundation/Foundation.h>
    #import "FBConnect.h"

    @interface FacebookFetchter : NSObject <FBDialogDelegate,FBSessionDelegate,FBRequestDelegate> {
        Facebook *facebook;
        FacebookFetchter *facebookFetcher;  }

    @property (nonatomic, retain) IBOutlet UIWindow *window;  @property (retain) Facebook *facebook; @property (retain) FacebookFetchter
*facebookFetcher; @end

    //  FacebookFetchter.m
    #import "FacebookFetchter.h"

    @implementation FacebookFetchter @synthesize facebookFetcher,facebook;

    -(void)login{
        NSLog(@"facebook login...");
        facebook = [[Facebook alloc] initWithAppId:@"..."]; //took the id out
        NSArray *permissions =  [[NSArray arrayWithObjects: 
                                  @"read_stream", @"offline_access", @"user_photos", @"user_photo_video_tags" , @"friends_photo_video_tags", @"friends_photos",@"friends_about_me",@"user_about_me",@"manage_friendlists",@"read_friendlists",@"user_birthday",@"friends_birthday", nil] retain];

        [facebook authorize:permissions delegate:self];

    }

    ...
    -(void)fbDidLogin {
        NSLog(@"Erfolgreich eingeloggt...."); } ...

    @end

In my delegate I implemented this and I also set up the plist with the fbapp_id url scheme

- (BOOL)application:(UIApplication *)application handleOpenURL:(NSURL *)url { 
    NSLog(@"AppDelegate handleOpenURL");
    return [[[settings facebookFetcher] facebookFetcher] handleOpenURL:url];
}

there settings is my view controller:

//settings.h @interface Settings : UIViewController {
    FacebookFetchter *facebookFetcher;
    //Facebook *facebook; }

@property (retain) FacebookFetchter
*facebookFetcher;
- (IBAction)sync; @end

//settings.m @synthesize facebookFetcher;

//within this action the facebook login is called
- (IBAction)sync{
    NSLog(@"sync...");
    facebookFetcher = [[FacebookFetchter alloc] init];
    [facebookFetcher login]; }

Any suggestions??

Thank you!

Answer 1

I just had this problem and believe I may have found your solution. When you create the app on facebook you must edit your app settings to allow for native ios app. The ios bundle id selected must match EXACTLY to your bundle ID in the app you are creating. Facebook states that they check this prior to authorizing your app. Funny thing is if you remove the facebook app from the device and then try to authenticate it uses the web browser and seemingly bipasses this "security" completely. Facebook doesn't send an error message back so it was a lot of fun to track down. I figured I'd throw this answer out there in hopes to save some future devs some trouble. I hope this helps.

I had the same issue. I had not set the permissions for facebook access. I wrote an extra line of code

NSArray *permissions = [[NSArray arrayWithObjects:@"read_stream",@"offline_access","publish_stream", nil] retain];

Its working perfectly.

I encountered the same problem. For me it was solved by unchecking the "Application does not run in background" property in the Info plist.
