如何使UITableView标题可选？

Question

我为UITableView制作了一个自定义节标题，其中包含一些控件，如分段控件，UIImageView等。它成功出现，但它不能点击，所以我无法与其控件进行交互。

我需要知道如何使这个标题视图可选？

Answer 1

创建一个自定义视图，用作节头视图并实现方法 - (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event，它会在您的手指点击它时被调用。

Answer 2

创建一个自定义部分headerView ..然后添加点击手势。

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 3

有没有办法与UITableViewDelegate做到这一点。

你有一个UITapGestureRecognizer添加到yourHeaderView像：

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 

为SWIFT 3.0

let tapGesture = UITapGestureRecognizer(target: self, action: #selector(YOURVIEWCONTROLLER.TapGestureRecognizer(_:))) 
yourHeaderView.addGestureRecognizer(tapGesture) 

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

可能会有所帮助。

快乐编码。

我在斯威夫特实现：

在你UITableViewController：

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 
    } 
} 

Answer 5

您可以简单地添加一个UIButton到你的头视图（或您的标题视图可以成为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{ 

} 

Answer 6

这个迅速解决：

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

然后实现

func gotoHeaderArticle() { 

} 

确保使您的通话视图 - 控制坚持UIGestureRecognizerDelegate

这里是我工作：

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") 
}

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) 
    {

更新雨燕3.1

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

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

Answer 10

这里是我工作

-(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); 

}
