swift cell自定义左滑手势处理，代码如下所示：
public override init(style: uitableviewcell.cellstyle, reuseidentifier: string?) {
super.init(style: style, reuseidentifier: reuseidentifier)
initui()
makerlayout()
/// 直接调用手势方法-手势添加在了contentview上
makerpang()
}
private func makerpang(){
let p = uipangesturerecognizer(target: self,action: #selector(pangaction(_:)))
p.delegate = self
contentview.addgesturerecognizer(p)
}
@objc func pangaction(_ guest: uipangesturerecognizer){
let state = guest.state
let x = guest.location(in: self).x
if state == .began{
startp = x-conview.mm_x
}else{
let gap = x-startp
if state == .changed{
if gap<0 {
conview.mm_x = max(x-startp, -140)
}else{
conview.mm_x = gap
}
}else{
uiview.animate(withduration: 0.2) {
self.conview.mm_x = gap <= -70 ? -140 : 0
}
}
}
}
