我通过约束做了一些简单的技巧。我做了tableView cell这是可扩展的。在 cell 点击它会打开新单元格（黑色）（下面是图片以便于理解）。
我的问题是如何使用顶部单元格内的按钮使其工作，该按钮看起来像“V”。如果点击cell，我希望它至少旋转90°。我怎么能实现它。
这是我扩展的方式：
override func tableView(tableView: UITableView, heightForRowAtIndexPath indexPath: NSIndexPath) -> CGFloat {
if(selectedIndex == indexPath.row){
return 210
}else{
return 135
}
}
override func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {
if (selectedIndex == indexPath.row){
selectedIndex = -1
}else{
selectedIndex = indexPath.row
}
self.productstable.beginUpdates()
self.productstable.reloadRowsAtIndexPaths([indexPath], withRowAnimation: UITableViewRowAnimation.Automatic)
self.productstable.endUpdates()
}

在您的自定义单元格中声明typealias arrowButtonTappedBlock = (button:UIButton) -> Void
，如下所示：
closure并点击箭头按钮点击动作，如下所示调用闭包：
var arrowButtonTapped : arrowButtonTappedBlock!
并在if arrowButtonTapped != nil {
arrowButtonTapped(button: sender as! UIButton)
}
中：设置关闭并执行您在cellForRowAtIndexPath
didSelectRowAtIndexPath:答案 1 :(得分：0)
您可以轻松地做到这一点
Delare var selectedRowIndex = -1
为您的自定义单元创建协议
protocol TableViewCellDelegate {
func BtnExpendTapped(_ cell: CustomCell) }
在“自定义单元格声明”协议中，并为按钮添加操作方法
var delegate: TableViewCellDelegate?
@IBAction func actionExpendBtnTap(_ sender: UIButton){
delegate?.BtnExpendTapped(self)
}
在“行高”方法中，将“ Expended”和“正常”高度添加为要求
func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {
if indexPath.row == selectedRowIndex {
return 270 //Expanded
}
return 138.5 //Not expanded
}
在视图控制器中使用协议委托并添加委托方法
func BtnExpendTapped(_ cell: CustomCell) {
if let indexPath = tblView.indexPath(for: cell) {
if selectedRowIndex == indexPath.row {
selectedRowIndex = -1
} else {
selectedRowIndex = indexPath.row
}
tblView.reloadRows(at: [indexPath], with: .none)
}
}
