How to detect one button in UITableviewCell
, I have 10 UIButton
in UITableViewCell
, next when I click on UIButton
then it detects multiple buttons, (as like odd number list). my UITableView
is with paging enabled. Here is my all code.
表格视图
class HomeViewController: UIViewController, UITableViewDelegate,UITableViewDataSource {
@IBOutlet weak var homeTableView: UITableView!
let mainArray = [["1","2","3","4"],["5","6","7","8"],["9","10","11","12"],["13","14","15","16"]]
override func viewDidLoad() {
super.viewDidLoad()
self.homeTableView.delegate = self
self.homeTableView.dataSource = self
}
func numberOfSections(in tableView: UITableView) -> Int {
return mainArray.count
}
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return mainArray[section].count
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "HomeTableViewCell", for: indexPath) as! HomeTableViewCell
return cell
}
func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {
return self.view.frame.size.height
}
}
TableViewCell
class HomeTableViewCell: UITableViewCell {
@IBOutlet weak var bookMarkBtn: UIButton!
@IBAction func bookMarkBtnAction(_ sender: UIButton) {
sender.isSelected = !sender.isSelected
if(sender.isSelected == true)
{
sender.setImage(UIImage(named:"favorite_blue"), for: UIControlState.normal)
}
else
{
sender.setImage(UIImage(named:"favorite_white"), for: UIControlState.normal)
}
}
}
要检测 UITableViewCell
中的 UIButton
,您可以采用以下任一方法:
To detect a UIButton
in a UITableViewCell
, you can follow any of the below approaches:
1.使用 UIButton
IBOutlets
您可以创建一个 IBOutlet
对应于 UITableViewCell
中的每个 UIButton
并使用这些 outlet 来识别执行哪个按钮操作.
You can create an IBOutlet
corresponding to each UIButton
in the UITableViewCell
and use those outlets to identify which button action is performed.
示例:
class CustomCell: UITableViewCell
{
@IBOutlet weak var button1: UIButton!
@IBOutlet weak var button2: UIButton!
@IBOutlet weak var button3: UIButton!
@IBOutlet weak var button4: UIButton!
@IBOutlet weak var button5: UIButton!
@IBAction func onTapButton(_ sender: UIButton)
{
if sender === button1
{
//button1 specific code here
}
else if sender === button2
{
//button2 specific code here
}
//and so on..
}
}
<强>2.使用 UIButton
Tag
属性
2. Use UIButton
Tag
property
您可以为 UITableViewCell
中的每个 UIButton
提供一个 tag
值,然后使用该标签来识别特定按钮.
You can provide a tag
value to each of the UIButton
present in the UITableViewCell
and then use that tag to identify the specific button.
示例:
class CustomCell: UITableViewCell
{
@IBAction func onTapButton(_ sender: UIButton)
{
if sender.tag == 1
{
//button1 has a tag = 1
//button1 specific code here
}
else if sender.tag == 2
{
//button2 has a tag = 2
//button2 specific code here
}
//and so on..
}
}
要在 UIButton 的选中/未选中状态下设置不同的图像,您可以使用情节提要:
For setting different images in selected/unselected state of UIButton, you can use storyboard for that:
对于未选中状态:
对于选定状态:
如果您仍然遇到任何问题,请告诉我.
