I got authorization from the app, but when i try to publish i am getting an error Error: HTTP status code: 400 below i am posting my code

 - (void)viewDidLoad
{
self.postParams =
 [[NSMutableDictionary alloc] initWithObjectsAndKeys:
 @"https://developers.facebook.com/ios", @"link",
 @"https://developers.facebook.com/attachment/iossdk_logo.png", @"picture",
 @"Facebook SDK for iOS", @"name",
 @"build apps.", @"caption",
 @"testing for my app.", @"description",
 nil]; 

[self.postParams setObject:@"hgshsghhgsls" forKey:@"message"];

[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
}

-(IBAction)Post{
AppDelegate *appDelegate = [UIApplication sharedApplication].delegate;
[appDelegate openSessionWithAllowLoginUI:YES];


[FBRequestConnection   startWithGraphPath:@"me/Mac" parameters:self.postParams HTTPMethod:@"POST"
                        completionHandler:^(FBRequestConnection *connection,id result,NSError *error) {
                            NSString *alertText;
                             if (error) {
                             alertText = [NSString stringWithFormat:@"error: domain = %@, code = %d, des = %d",error.domain, error.code,error.description];
                             } 
                             else 
                             {
                             alertText = [NSString stringWithFormat:@"Posted action, id: %@",[result objectForKey:@"id"]];
                             }
                             // Show the result in an alert
                             [[[UIAlertView alloc] initWithTitle:@"Result" message:alertText delegate:self cancelButtonTitle:@"OK!"
                             otherButtonTitles:nil]show];
                        }]; 




}

What am i doing wrong here and any suggestion will be great and this new SDK is a beta version ? or a complete one ?

Answer 1

如果您遇到任何问题，请尝试在您有兴趣调试的请求调用之前添加此代码来启用日志记录：

[FBSettings setLoggingBehavior:[NSSet setWithObjects:FBLoggingBehaviorFBRequests, FBLoggingBehaviorFBURLConnections, nil]];

Answer 2

最后我解决了问题，我必须在我的应用权限页面中将Auth Token参数更改为URLFragment然后它正在工作

Answer 3

i used this framework for my project. it works properly. this is my related code

   -(IBAction)logIn:(id)sender;
{
AppDelegate *appdelegate = (AppDelegate *)[[UIApplication sharedApplication] delegate];
if (!FBSession.activeSession.isOpen) {
    [appdelegate sessionOpener];
}
else {
    [self loginHelp];
}

and my sessionOpener function is;

 -(void) sessionOpener

{

[FBSession sessionOpenWithPermissions:nil
                    completionHandler:^(FBSession *session,
                                        FBSessionState status,
                                        NSError *error) {
                        // session might now be open.
                        if (!error) {
                            [self.viewController loginHelp];
                        }
                    }];

 NSLog(@"%d", FBSession.activeSession.isOpen);
NSLog(@"%@", FBSession.activeSession.description );

}

it works for me. may be helpful to you.

check Session Publish Permissions.

its worked me fine.

[FBSession openActiveSessionWithPublishPermissions:[[NSArray alloc] initWithObjects:@"publish_stream",@"email", nil]
                                   defaultAudience:FBSessionDefaultAudienceFriends
                                      allowLoginUI:YES
                                 completionHandler:^(FBSession *session,
                                                     FBSessionState state, NSError *error) {
                                     [self sessionStateChanged:session state:state error:error];
                                 }];
