Sending a info to detailview from UICollectionView is not working? - ios

Question

I think i didnt explain well in the title, heres the problem, I have a collection view that is supplying from a json, but when I go to the detail it crashes, i think the problem is in this part of the code when I send the info to the detail:
-(void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender{
if ([[segue identifier]isEqualToString:#"detailView"]) {
NSIndexPath *myIndexPath = [self.collectionView indexPathsForSelectedItems];
int row = [myIndexPath row];
MenuDetailViewController *menu = [segue destinationViewController];
EntryJson *entry = [[InfoWeb sharedInstance] entryAtIndex:row];
menu.galeriademo = entry.imagenes;
menu.DetailModalprim = #[entry.title == nil ? #"" : entry.title,
entry.date == nil ? #"" : entry.date,
entry.desc == nil ? #"" : entry.desc,
entry.mainimage == nil ? #"" : entry.mainimage,
entry.seccion == nil ? #"" : entry.seccion];
}
}
In a tableview the IndexPath would be like: NSIndexPath *myIndexPath = [self.collectionView indexpathforselectedRow];
I had a tableview working like this and it was fine but when I change to a collection view i had this problem. The crash log is the next:
2014-03-07 12:41:00.696 CMT[28640:70b] -[__NSArrayI row]: unrecognized selector sent to instance 0xc34d180
2014-03-07 12:41:00.698 CMT[28640:70b] *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[__NSArrayI row]: unrecognized selector sent to instance 0xc34d180'
So I need your help! Thanks!

Answer 1

indexPathsForSelectedItems returns an NSarray, not an NSIndexPath
NSIndexPath *myIndexPath = [self.collectionView indexPathsForSelectedItems];
should be
NSArray *myIndexPaths = [self.collectionView indexPathsForSelectedItems];
NSIndexPath *myIndexPath = [myIndexPahts objectAtIndex:0];
