ios - 如何使 UITableView 标题可选择？

Question

我为 UITableView 制作了一个自定义部分标题，其中包括一些控件，如分段控件、UIImageView 等。它已成功显示，但不可点击，因此我无法与其控件进行交互。

我需要知道如何让这个标题 View 可选？

UITableViewDelegate 无法做到这一点。

您必须将 UITapGestureRecognizer 添加到您的 HeaderView 中，例如:

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

适用于 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

添加继承的UIGestureRecognizerDelegate类引用

let tap = UITapGestureRecognizer(target: self, action:#selector(self.handleTap(_:)))
tap.delegate = self
self.view.addGestureRecognizer(tap)

  @objc func handleTap(_ sender: UITapGestureRecognizer) {
        //Do your work 
    }

可能会有帮助。

快乐编码。
