IOS UICollectionView Register nib for UICollectionViewCell not working

Question

here's my code :

- (void)viewDidLoad {
    [super viewDidLoad];
   ...
    UICollectionViewFlowLayout *layout=[[UICollectionViewFlowLayout alloc] init];
    [layout setItemSize:CGSizeMake(160, 160)];
    [layout setMinimumInteritemSpacing:5.f];
    [layout setScrollDirection:UICollectionViewScrollDirectionHorizontal];

    _photoPicker = [[UICollectionView alloc] initWithFrame:CGRectMake(10, 10 , self.view.frame.size.width - 20, 160 ) collectionViewLayout:layout];
    [_photoPicker registerNib:[UINib nibWithNibName:@"photoUploadCollectionViewCell" bundle:nil] forCellWithReuseIdentifier:@" photoUploadCell"];

    //[_photoPicker registerClass:[photoUploadCollectionViewCell class] forCellWithReuseIdentifier:@"photoUploadCell"];
    _photoPicker.backgroundColor = gray;
    _photoPicker.delegate = self;
    _photoPicker.dataSource = self;
    [self.scrollView addSubview:_photoPicker];

}
-(UICollectionViewCell *)collectionView:(UICollectionView *)collectionView cellForItemAtIndexPath:(NSIndexPath *)indexPath{
    photoUploadCollectionViewCell *cell=[collectionView dequeueReusableCellWithReuseIdentifier:@"photoUploadCell" forIndexPath:indexPath];

}

This code crash at photoUploadCollectionViewCell *cell=[collectionView dequeueReusableCellWithReuseIdentifier:@"photoCell" forIndexPath:indexPath]; and I get this error :

2015-05-26 10:45:29.363 Free Sale[4505:55482] * Assertion failure in -[UICollectionView _dequeueReusableViewOfKind:withIdentifier:forIndexPath:viewCategory:], /SourceCache/UIKit_Sim/UIKit-3347.44/UICollectionView.m:3454 2015-05-26 10:45:29.374 Free Sale[4505:55482] * Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'could not dequeue a view of kind: UICollectionElementKindCell with identifier photoCell - must register a nib or a class for the identifier or connect a prototype cell in a storyboard' *** First throw call stack:

Any one know this wired issue ?

Answer 1

photoCell is not registered.. is this the actual code you have? because you have a white space forCellWithReuseIdentifier: remove the white space..

Happy coding, Cheers!

Answer 2

Notice the code :

[_photoPicker registerNib:[UINib nibWithNibName:@"photoUploadCollectionViewCell" bundle:nil] forCellWithReuseIdentifier:@" photoUploadCell"];

Remove the white space from @" photoUploadCell"

Hope this will fix your problem

Answer 3

You registered it with a different namephotoUploadCell, than the one you use later on photoCell.
