I am trying to implement a search bar in a UICollectionView as a UICollectionViewReusableView
This way I am not using a UISearchController but I am changing the datasource of the collectionview
In my custom layout I am adding the searchbar this way:
override func prepareLayout() {
super.prepareLayout()
var searchBarAttributes = UICollectionViewLayoutAttributes(forSupplementaryViewOfKind: TeacherSearchbarIdentifier, withIndexPath: NSIndexPath(forItem: 0, inSection: 0))
searchBarAttributes.frame = CGRectMake(0, 0, collectionViewContentSize().width, 44)
searchBarAttributes.zIndex = 100
miscAttributes.append(searchBarAttributes)
}
override func layoutAttributesForElementsInRect(rect: CGRect) -> [AnyObject]? {
var attributes = [UICollectionViewLayoutAttributes]()
for (idx, attr) in enumerate(miscAttributes) {
if CGRectIntersection(rect, attr.frame) != CGRectNull {
attributes.append(attr)
}
}
return attributes
}
I am setting the delegate like this:
func collectionView(collectionView: UICollectionView, viewForSupplementaryElementOfKind kind: String, atIndexPath indexPath: NSIndexPath) -> UICollectionReusableView {
var view = collectionView.dequeueReusableSupplementaryViewOfKind(kind, withReuseIdentifier: kind, forIndexPath: indexPath) as! UICollectionReusableView
if kind == TeacherSearchbarIdentifier {
controller.searchBar = (view as! TeacherSearchView).searchBar
return view
}
}
The variable controller is the UICollectionViewController which implements the UISearchBarDelegate Protocol
The delegate is set in didSet of the searchBar variable. These are my delegates:
override func scrollViewDidScroll(scrollView: UIScrollView) {
self.view.endEditing(true)
}
func searchBarShouldBeginEditing(searchBar: UISearchBar) -> Bool {
searchBar.setShowsCancelButton(true, animated: true)
return true
}
func searchBarShouldEndEditing(searchBar: UISearchBar) -> Bool {
searchBar.setShowsCancelButton(false, animated: true)
searchBar.resignFirstResponder()
return true
}
func searchBarCancelButtonClicked(searchBar: UISearchBar) {
searchBar.setShowsCancelButton(false, animated: true)
searchBar.resignFirstResponder()
}
Now my problem!
When I am tapping on the search bar, the keyboard appears. If I press the cancel button or scroll, it dissappears. Just as I want it to. This also works a second time.
BUT!
If I do this a third time, I get a EXC_BAD_ACCESS:
I tried turning on Enabling Zombie Objects, but no information was provided. I also tried profiling for Zombie Objects, it just crashes without any noticeable information.
Please help me on how I can resolve this error, or give me further debugging instructions.
