iphone - Why are my images not displayed -

i have class inherits uiviewcontroller lets call 'controller' outlet uicollectionview. class inherited uicollectioncell lets call 'a' , uiimage lets call 'b', has outlet of b

i wrote following code in 'controller':

- (uicollectionviewcell *)collectionview:(uicollectionview *)p_collectionview    cellforitematindexpath:(nsindexpath *)p_indexpath {     uicollectionviewcell* cell = [self getuicollectionviewcellfromcollectionview:p_collectionview atindexpath:p_indexpath];     if([cell iskindofclass:[imagecollectionviewcell class]] == yes)     {         //draw image inside view         imagecollectionviewcell* imagecell = (imagecollectionviewcell*)cell;         nsstring* imageurl = self.objecttoshow.imagesurl[p_indexpath.item];         uiimage* currentimage = [[uiimage alloc] initwithcontentsoffile:imageurl];         imagecell.imageview.image = currentimage;     }      return cell; } 

everything initialized correctly images not displayed, have no clue why is.

can me?

initwithcontentsoffile: expects file path, not url. if you're using url, should using initwithcontentsofurl: takes nsurl (not nsstring), you'll have pass [nsurl urlwithstring: imageurl].
