objective c - how to share image on Facebook in iphone -


i'm facing problem in code. i'm using code:

//create uiimage (you use picture album or camera too)  nsdata *imagedata = uiimagejpegrepresentation(imgview.image, 8.0); uiimage *picture = [uiimage imagewithdata:imagedata];  //create fbgraphfile object insance , set picture wish publish on fbgraphfile *graph_file = [[fbgraphfile alloc] initwithimage:picture];  //finally, set fbgraphfileobject onto our variables dictionary.... [variables setobject:graph_file forkey:@"file"];     [variables setobject:@"i'm testing iphone app" forkey:@"message"];  //the fbgraph object smart enough recognize binary image data inside fbgraphfile //object , treat such..... fbgraphresponse *fb_graph_response = [fbgraph dographpost:@"117795728310/photos" withpostvars:variables]; nslog(@"postpicturebuttonpressed:  %@", fb_graph_response.htmlresponse);     nslog(@"now log facebook , @ profile & photo albums...");

in code, exc_bad_access error message, image posted on facebook.

how can solve problem?

-(void)postinappfacebook {     nsmutabledictionary *variables = [nsmutabledictionary dictionarywithcapacity:3];     uiimage *picture = filterimage;     fbgraphfile *graph_file = [[fbgraphfile alloc] initwithimage:picture];     [variables setobject:graph_file forkey:@"file"];     [variables setobject:[nsstring stringwithformat:@"hello testin"] forkey:@"message"];     [fbgraph dographpost:@"me/photos" withpostvars:variables];     nslog(@"now log facebook , @ profile & photo albums...");  }
