UICollectionView custom button actions in Swift 3 - ios

Question

I have used UICollectionView and I am populating it with results from API. There is a ID, Image, Name, Description and Liked true or false coming in API.
I have implemented all these things and now all the results loads inside this collection view.
extension VCResCourses : UICollectionViewDelegate {
}
extension VCResCourses: UICollectionViewDelegateFlowLayout {
func collectionView(_ collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, sizeForItemAt indexPath: IndexPath) -> CGSize
{
let length = (UIScreen.main.bounds.width - 16)
return CGSize(width: length, height: 135);
}
}
extension VCResCourses : UICollectionViewDataSource {
func numberOfSections(in collectionView: UICollectionView) -> Int {
return 1
}
func collectionView(_ collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int {
return dataSources.numbeOfRowsInEachGroup(section)
}
func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
let currentCell = collectionView.dequeueReusableCell(withReuseIdentifier: cellIdentifier,for:indexPath) as! CVCResCourse
let doCourses: [DOCourses] = dataSources.total()
let doCourse = doCourses[indexPath.row]
let courseId = doCourse.Id!
var courseName = doCourse.Name!
let courseAddress = doCourse.Address!
let courseImage = doCourse.Image!
let courseWish = doCourse.Wish!
courseName = courseName.replacingOccurrences(of: "\t", with: "", options: .literal, range: nil)
currentCell.imageView.kf.setImage(with: URL(string: courseImage))
currentCell.textPrimary.text = courseName.capitalized
currentCell.textSecondary.text = courseAddress.capitalized
currentCell.buttonOpen.addTarget(...)
currentCell.buttonFav.addTarget(...)
return currentCell
}
}
What I am trying now is there are two button on each CELL one opens details of the record and other set favourite to true or false.
Now I need to get id of the current record and toggle its favourite state to true or false or open the detail page using the id. I am not able to add action for buttons and perform the favourite or open detail action using ID.
In android I have done this by adding clickListener inside CustomBaseAdapter which perform actions for each row or record of the data. I need to do the same in iOS as well but no luck yet
I am new to iOS development please help

Answer 1

you need to set tag for each button for e,g
currentCell.buttonOpen.tag = indexPath.row
currentCell.buttonFav.tag = indexPath.row
currentCell.buttonOpen.addTarget(self, action: #selector(self.buttonClicked), for: .touchUpInside)
and you can get id via button.tag, for e.g
func buttonClicked(_ sender: UIButton) {
let doCourses: [DOCourses] = dataSources.total()
let doCourse = doCourses[sender.tag]
let courseId = doCourse.Id!
print (courseId)
}
