这是一个奇怪(但应该很简单)的例子。我只是尝试点击一个自定义UITableViewCell并触发一个segue转到另一个ViewController。当单元格被点击时,didSelectRowAt indexPath不会触发,但奇怪的是,当单元格从右向左或从左向右滑动时,它就会触发。
我的didSelectRowAt indexPath**:**
func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
print("You selected cell number: \(indexPath.row)!")
self.performSegue(withIdentifier: "mySegue", sender: self)
}My ViewController:
import UIKit
class myViewController: UIViewController, UITableViewDelegate, UITableViewDataSource, UIPickerViewDelegate {
var myData = NSDictionary()
override func viewDidLoad() {
super.viewDidLoad()
fetchMyData()
self.tableView.delegate = self
self.tableView.dataSource = self
self.tableView.rowHeight = 100
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
}
func fetchMyData() {
// ... fetches my data
}

func numberOfSections(in tableView: UITableView) -> Int {
return 1
}

return myData.count
}
//delegate information to cells in table rows
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
print("running tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell...")
// Dequeue cell
let cell = tableView.dequeueReusableCell(withIdentifier: "cell", for: indexPath) as! myCustomCell
cell.cellAmount!.text = "Hello World"
cell.cellTextField2!.text = "Some info"
cell.cellTextField3!.text = "Some other info"
cell.backgroundCardView.backgroundColor = UIColor.red
cell.backgroundCardView.layer.cornerRadius = 8.0

cell.backgroundCardView.layer.shadowColor = UIColor.black.withAlphaComponent(0.9).cgColor

}我已经尝试过以下几种方法:
User Interaction Enabled。debugger navigator,并且可以看到当我点击一个单元格(
)。也许有一种更深一步的方法,看看为什么那个水龙头不会触发didSelectRowAt indexPath。
有人知道什么可能会导致didSelectRowAt indexPath 在被窃听时不会被触发吗?

我面临着同样的问题,并找到了一个适用于我的答案,here。我在viewWillAppear中有一段键盘解散代码:
self.view.addGestureRecognizer(UITapGestureRecognizer(target: self.view, action: #selector(UIView.endEditing(_:))))在评论完这句话后,点击开始工作!但现在,我必须找到更好的方法,键盘解散。)请检查您的出口,可能您使用了类似的解决方案键盘解散。
