我有一个自定义视图,其中包含如下所示的集合视图集.
func setupCollectionView() {
let layout = UICollectionViewFlowLayout()
layout.sectionInset = UIEdgeInsets(top: scaled(height: 15),left: scaled(width: 35),bottom: scaled(height: 15),right: scaled(width: 35))
layout.itemSize = CGSize(width: scaled(width: 30),height: scaled(width: 30))
layout.minimumLineSpacing = 15
layout.minimumInteritemSpacing = 30
collectionView = UICollectionView(frame: CGRect.zero,collectionViewLayout: layout)
collectionView.showsVerticalScrollIndicator = false
collectionView.showsHorizontalScrollIndicator = false
collectionView.register(THTexasHoldemEmojiCell.self,forCellWithReuseIdentifier: THTexasHoldemEmojiCell.className)
}
和委托功能
extension THTexasHoldemEmojisView {
func setupDelegates() {
collectionView.dataSource = self
collectionView.delegate = self
}
}
extension THTexasHoldemEmojisView: UICollectionViewDelegate {
func collectionView(_ collectionView: UICollectionView,didHighlightItemAt indexPath: IndexPath) {
print("did highlight item")
}
func collectionView(_ collectionView: UICollectionView,didSelectItemAt indexPath: IndexPath) {
print("did select item")
}
}
奇怪的是didHighlightItem函数可以调用,但didSelectItem不会.我错过了什么吗？谢谢你的帮助.
我的视图连接是UIViewController(THController)持有UIView(THEmojisView),THEmojisView持有集合视图.
在THController中我有很多观点和动作,但不包括THEmojisView.
THController的touchesBegan(_ touches：Set,with event：UIEvent？)是否有可能影响集合视图的委托函数？
