How to make UITableView Header selectable?

Question

I have made a custom section-header for UITableView, that includes some controls like segmented control, UIImageView ,etc. It successfully appears, but it's not tappable so I can't interact with its controls.

I need to know how can I make this header view selectable?

Answer 1

There is no way to do it with the UITableViewDelegate.

You have to add a UITapGestureRecognizer to yourHeaderView Like:

UITapGestureRecognizer *singleTapRecognizer = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(gestureHandler:)]; [singleTapRecognizer setDelegate:self]; singleTapRecognizer.numberOfTouchesRequired = 1; singleTapRecognizer.numberOfTapsRequired = 1;    [yourHeaderView addGestureRecognizer:singleTapRecognizer];   -(void) handleGesture:(UIGestureRecognizer *)gestureRecognizer; //do in this method whatever you want 

FOR Swift 3.0

let tapGesture = UITapGestureRecognizer(target: self, action: #selector(YOURVIEWCONTROLLER.TapGestureRecognizer(_:))) yourHeaderView.addGestureRecognizer(tapGesture)  func TapGestureRecognizer(gestureRecognizer: UIGestureRecognizer) {     //do your stuff here  } 

Swift >= 4.0

Add UIGestureRecognizerDelegate class reference inherited

let tap = UITapGestureRecognizer(target: self, action:#selector(self.handleTap(_:))) tap.delegate = self self.view.addGestureRecognizer(tap)    @objc func handleTap(_ sender: UITapGestureRecognizer) {         //Do your work      } 

may be it will help.

Happy Coding.

If you need to know the index of the tapped section, you can use the following pattern (Swift 4) :

func tableView(_ tableView: UITableView, viewForHeaderInSection section: Int) -> UIView? {     let view = UIView(frame: CGRect(x: 0, y: 0, width: 300, height: 44))      // Configure your view here     // ...      let tapGestureRecognizer = UITapGestureRecognizer(         target: self,         action: #selector(headerTapped(_:))     )     view.tag = section     view.addGestureRecognizer(tapGestureRecognizer)     return view }  @objc func headerTapped(_ sender: UITapGestureRecognizer?) {     guard let section = sender?.view?.tag else { return }      // Use your section index here     // ... }
