Question

我为UITableView制作了一个自定义的section-header，其中包括一些控件，如分段控件，UIImageView等。它成功出现了，但它不具有可调性，因此我无法与其控件进行交互。

我需要知道如何才能使此标题视图可选？

Answer 1

使用 UITableViewDelegate无法做到这一点。

你必须在你的头视图中添加一个UITapGestureRecognizer，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

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＆gt; = 4.0

添加 UIGestureRecognizerDelegate 继承的类引用

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

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

可能会有所帮助。

快乐编码。

这对我有用：

override func tableView(tableView: UITableView, viewForHeaderInSection section: Int) -> UIView? {

    let v = UITableViewHeaderFooterView()
    v.textLabel?.text = "Header Text"
    let tapRecognizer = UITapGestureRecognizer(target: self, action: #selector(handleTap))
    tapRecognizer.delegate = self
    tapRecognizer.numberOfTapsRequired = 1
    tapRecognizer.numberOfTouchesRequired = 1
    v.addGestureRecognizer(tapRecognizer)
    return v
}

func handleTap(gestureRecognizer: UIGestureRecognizer)
{
    print("Tapped")
}

Swift 3.0的简单解决方案

 func tableView(_ tableView: UITableView, viewForHeaderInSection section: Int) -> UIView? {

        let v = UITableViewHeaderFooterView()
        let tapRecognizer = UITapGestureRecognizer(target: self, action: #selector(handleTap))
        v.addGestureRecognizer(tapRecognizer)
        return v
    }


    func handleTap(gestureRecognizer: UIGestureRecognizer)
    {
        controller?.view.endEditing(true)
    }

创建自定义部分headerView ..然后添加Tap手势。

UITapGestureRecognizer * recognizer = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(handleTap:)];

//This method will be called on Tap of section header
- (void)handleTap:(UITapGestureRecognizer *)sender {
//Do the action on Tap
}

Answer 5

创建用作节头视图的自定义视图并实现该方法 - (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event，当你的手指点击它时会调用它。

Answer 6

您只需在标题视图中添加UIButton（或者标题视图可以是UIButton本身）。

- (UIView *)tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section{

        static NSString *cellIdentifier = @"cellIdentifier";

    UITableViewCell *cell = (UITableViewCell*)[tableView dequeueReusableCellWithIdentifier:cellIdentifier];

    UIButton *cellButton = (UIButton*)[cell viewWithTag:1];
    [cellButton addTarget:self action:@selector(premiumSectionClicked:) forControlEvents:UIControlEventTouchUpInside];

    return cell;
}

-(void)buttonTapped:(id)sender{

}

我在Swift中的实现：

在UITableViewController：

中

let myView = MyView()

let tapRecognizer = UITapGestureRecognizer(target: myView, action: "handleTap")
myView.addGestureRecognizer(tapRecognizer)

self.tableView.tableHeaderView = myView

在MyView：

class MyView: UIView {

    func handleTap() {
        // Handle touch event here
    }
}

快速解决此问题：

let tapR : UITapGestureRecognizer = UITapGestureRecognizer(target: self, action: "gotoHeaderArticle")
tapR.delegate = self
tapR.numberOfTapsRequired = 1
tapR.numberOfTouchesRequired = 1
yourView.addGestureRecognizer(tapR)

然后实施

func gotoHeaderArticle() {

}

确保让您的调用viewcontroller遵循UIGestureRecognizerDelegate

如果您需要了解所点击部分的索引，可以使用以下模式（ 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
    // ...
}

Swift 3.1的更新

let tapGesture = UITapGestureRecognizer(target: self, action: #selector(TapGestureRecognizer(gestureRecognizer:)))
yourView.addGestureRecognizer(tapGesture)

func TapGestureRecognizer(gestureRecognizer: UIGestureRecognizer) {
        //do your stuff here
        print("Gesture")
    }

Answer 11

这对我有用

  -(UIView *)tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section{
        static NSString *cellIdentifier = @"cellIdentifier";
    YourHeaderTableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:cellIdentifier];
   cell.imageView.image = [image imageNamed:@"imageName"];
cell.segmentedControl.tag = section;
[cell.segmentedControl addTarget:self
                     action:@selector(action:)
           forControlEvents:UIControlEventValueChanged];
    return cell;
}

- (void)action:(id)sender{
    UISegmentedControl *segmentedControl = (UISegmentedControl *) sender;
    NSLog(@"selected section:%ld",(long)segmentedControl.tag);

}

如果任何人都需要一个解决方案，该解决方案可以在表视图具有多个部分时起作用，那么我遇到了同样的问题，我想到的解决方案是基于viewForHeaderInSection方法在按钮上创建不同的目标。部分。我使用的是按钮，但它与UITapGestureRecognizer一样适用

func tableView(_ tableView: UITableView, viewForHeaderInSection section: Int) -> UIView? {

        // ...

        if section == 0 {
            cell.button.addTarget(self, action: #selector(firstSectionTapped(_:)), for: .touchUpInside)
        } else if section == 1 {
            cell.button.addTarget(self, action: #selector(secondSectionTapped(_:)), for: .touchUpInside)
        }

        // ...

}

然后在ViewController中：

@objc func goalCategoryTapped(_ sender: UITapGestureRecognizer?) {
    print("Section One Tapped")
}

@objc func ideaCategoryTapped(_ sender: UITapGestureRecognizer?) {
    print("Section Two Tapped")
}
