new ios development,

app worked fine in ios 7 upon release of ios 8, app wouldn't open, set breakpoit led me home screen , line. appears there issue pulling image url correct. xcode output - uiimageview setimagewithurl:placeholderimage:]: im struggling find solve it

[cell.imagelabel setimagewithurl:[nsurl urlwithstring:imageurl]

here bit more code setting data

nsdatecomponents *components = [[nscalendar currentcalendar] components:nsdaycalendarunit | nsmonthcalendarunit | nsyearcalendarunit fromdate:[nsdate date]]; nsinteger month = [components month]; nsinteger year = [components year];  _images = @[[nsstring stringwithformat:@"http://w***.jpg?month=%i&year=%i", month, year],                  [nsstring stringwithformat:@"http://***.jpg?month=%i&year=%i", month, year],                  [nsstring stringwithformat:@"http://***.jpg?month=%i&year=%i", month, year],                  [nsstring stringwithformat:@"http://***.jpg?month=%i&year=%i", month, year],                  [nsstring stringwithformat:@"http://***.jpg?month=%i&year=%i", month, year],                  [nsstring stringwithformat:@"http://***.jpg?month=%i&year=%i", month, year],                  @"television.png"]; 

this code configure cell:

// configure cell...

int row = [indexpath row]; cell.titlelabel.text = _title[row]; cell.desclabel.text = _description[row];  nsstring *imageurl = _images[row]; if(row < 6){     [cell.imagelabel setimagewithurl:[nsurl urlwithstring:imageurl]                     placeholderimage:[uiimage imagenamed:@"loading.png"]]; } else { cell.imagelabel.image = [uiimage imagenamed:_images[row]]; }   return cell; 

i think following code you,

int row = [indexpath row]; cell.titlelabel.text = _title[row]; cell.desclabel.text = _description[row];  nsstring *stringurl = _images[row];         nsurl *urlstr = [nsurl urlwithstring:stringurl];          alassetslibrary *library = [[alassetslibrary alloc] init];         [library assetforurl:urlstr resultblock:^(alasset *asset)          {               __block uiimage *assetthumbnailimage = [uiimage imagewithcgimage:asset];              dispatch_queue_t queue = dispatch_get_global_queue(dispatch_queue_priority_high, 0ul);               dispatch_async(queue, ^{                   uiimage *image = assetthumbnailimage;                  assetthumbnailimage = nil;                   dispatch_sync(dispatch_get_main_queue(), ^{                       cell.imagelabel.image = image;                   });              });            }                 failureblock:^(nserror *error)          {              // error handling              nslog(@"failure-----");          }];
