collectionView：UICollectionView，didSelectItemAt indexPath：未执行IndexPath

Question

Here is my image of collectionViewCell .

I have collectionView inside tableViewCell and I have a button inside collectionViewCell which is working perfectly as my wish. But What is troubling me is the function didSelectItemAt is not being called .

I tried with

mycollectionview.isUserInteractionEnabled = true
mycollectionview.allowsSelection = true

but still not working . Is the button inside collectionViewCell is the cause behind it as I read somewhere . If its is so how can I fix the issue .

Answer 1

Please confirm that you have set the delegate for the UICollectionView to your ViewController not the TableViewCell . If you have set the Delegate to UITableViewCell , then your didSelectItemAt will be called inside the TableViewCell's class

Answer 2

try this code in swift 4

cell.btnCart.addTarget(self, action: #selector(btnCartAction), for: .touchUpInside)

and handle the action

@objc func btnCartAction(sender:UIButton) {
        //write your code here
}

Answer 3

Check your all views which are placed on cell.If they have user interaction enabled and if user interaction enabled then what is the size of that item. It looks like some view is covering the whole cell that's why did select item does not get called.

Answer 4

请检查您的Button大小，tableView选择（单选或多次），检查tableView用户是否启用了交互，还检查数据源或委托是否已连接
