in delegate method

-(void)sharer:(id<fbsdksharing>)sharer didfailwitherror:(nserror *)error {       nslog(@"%@",error); }

the error log printed follows

error domain=com.facebook.sdk.share code=2 "the operation couldn’t completed. (com.facebook.sdk.share error 2.)" userinfo=0x7faec97bb660 {com.facebook.sdk:fbsdkerrorargumentvaluekey=<fbsdkshareopengraphcontent: 0x7faecbc16740>, com.facebook.sdk:fbsdkerrordevelopermessagekey=feed share dialogs support fbsdksharelinkcontent., com.facebook.sdk:fbsdkerrorargumentnamekey=sharecontent}

change [action setphoto:photo forkey:@"image"]; [object setphoto:photo forkey:@"og:image"];
