Why is my UICollectionViewCell touch event offset ? - ios

Question

I have a UICollectionView that is using the Flow Layout. At this point I'm not really doing anything special. I'm just programmatically adding the view and the UICollectionViewCell.
When you touch a cell it is registering the touch event for the cell that is located above it. So if you touch a cell on row 2 the the cell above is the one that actually registers the touch.
Here is the code that I have setting things up.
#interface KFYSearch() <UICollectionViewDataSource, UICollectionViewDelegate, UICollectionViewDelegateFlowLayout, UISearchBarDelegate>
#property(nonatomic, strong)UISearchBar *searchBar;
#property(nonatomic, strong)UICollectionView *collectionView;
#property(nonatomic, strong)NSArray *collectionData;
#end
#implementation KFYSearch
-(id)initWithView:(UIView*)view
{
self = [super init];
if(self)
self.view = view;
return self;
}
-(void)viewWillAppear:(BOOL)animated
{
[super viewWillAppear:animated];
if(_searchBar == nil)
{
self.view.frame = CGRectMake(20, 20, self.view.superview.frame.size.width - 40, self.view.superview.frame.size.height - 40);
[self.view setBackgroundColor:[UIColor whiteColor]];
[self createChildViews];
}
}
-(void)createChildViews
{
_searchBar = [[UISearchBar alloc] initWithFrame: CGRectMake(5, 5, self.view.frame.size.width - 10, 30)];
UICollectionViewFlowLayout *flowLayout = [[UICollectionViewFlowLayout alloc]init];
_collectionView = [[UICollectionView alloc] initWithFrame:CGRectMake(_searchBar.frame.origin.x, _searchBar.frame.origin.y + (_searchBar.frame.size.height + 2), _searchBar.frame.size.width, self.view.frame.size.height - ((_searchBar.frame.origin.y + _searchBar.frame.size.height) + 10)) collectionViewLayout:flowLayout];
_collectionView.dataSource = self;
_collectionView.delegate = self;
[_collectionView registerClass:[KFYKlickableCell class] forCellWithReuseIdentifier:#"Cell"];
[_collectionView setBackgroundColor:[UIColor whiteColor]];
[self.view addSubview:_searchBar];
[self.view addSubview:_collectionView];
[self getData];
}
-(void)getData
{
KFYGetKlickablesAction *getKlickablesAction = [[KFYGetKlickablesAction alloc]init];
_collectionData = [getKlickablesAction mockData];
[_collectionView reloadData];
}
