问题描述
我为表格单元格设置了领先的滑动动作，该动作已添加到购物车中.我尚未实现任何尾随滑动操作方法，但仍在获取每个单元格的删除操作.下面是我所有tableView方法的代码.我还附上了模拟器中的一张图片.
I have set a leading swipe action for tableview cell, which add to cart. I have not implemented any trailing swipe action method, still I am getting delete action for every cell. Below is my code of all tableView methods. I have also attached one image from simulator.
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return 10
}
func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {
if (indexPath.row == 0) {
return 267
}
else {
return 85
}
}
//tableview methods
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
//对于第一个单元格
if (indexPath.row == 0){
let cell = storeInfoTable.dequeueReusableCell(withIdentifier: "storeinfocell1", for: indexPath) as! CustomStoreInfoTableOneViewCell
return cell
}
//对于其余单元格
let cell = storeInfoTable.dequeueReusableCell(withIdentifier: "storeItemCell", for: indexPath) as! StoreItemsTableViewCell
cell.storeItemCellView.layer.cornerRadius = 5.0
return cell[![enter image description here][1]][1]
}
@available(iOS 11.0, *)
func tableView(_ tableView: UITableView, leadingSwipeActionsConfigurationForRowAt indexPath: IndexPath) -> UISwipeActionsConfiguration? {
if (indexPath.row == 0) {return nil}
let addToCart = UIContextualAction(style: .normal, title: "Add to Cart") { (action, view, nil) in
print("Added to cart")
let cell = self.storeInfoTable.cellForRow(at: indexPath) as! StoreItemsTableViewCell
if (Int(cell.numberOfItem.text!)! == 0) {
self.view.showToast(toastMessage: "Items must be atleast one", duration: 1.5)
}
else {
self.view.showToast(toastMessage: "Successfully added to cart", duration: 1.5)
}
}
addToCart.title = "Add to Cart"
addToCart.backgroundColor = #colorLiteral(red: 0.3647058904, green: 0.06666667014, blue: 0.9686274529, alpha: 1)
addToCart.image = UIImage(named: "cart")
return UISwipeActionsConfiguration(actions: [addToCart])
}
推荐答案
解决方案是在未定义任何动作的情况下实施尾随滑动动作.代码在下面.
Solution for this is to implement a trailing swipe action without any actions defined. code is below.
@available(iOS 11.0, *)
func tableView(_ tableView: UITableView, trailingSwipeActionsConfigurationForRowAt indexPath: IndexPath) -> UISwipeActionsConfiguration? {
return UISwipeActionsConfiguration.init()
}
