工具类中写好类方法

swift"> //MARK: 打开第三方APP
   static func openThirdPartyApp(_ url:String,_ appName:String){
        if let url = URL(string: url) {
            UIApplication.shared.open(url, options: [:]) { boolValue in
                if !boolValue {
                    kWindow.makeToast("请检查是否安装\(appName)App", position: .center)
                }
            }
        }
        else {
            kWindow.makeToast("请检查是否安装\(appName)App", position: .center)
        }
  }

使用

swift"> Utils.openThirdPartyApp("taobao://", "淘宝")
 Utils.openThirdPartyApp("pinduoduo://", "拼多多")
 Utils.openThirdPartyApp("openapp.jdmobile://", "京东")
 Utils.openThirdPartyApp("snssdk1128://", "抖音")
 Utils.openThirdPartyApp("weixin://", "微信")

打开快手有点特殊，需要单独写

swift">    //MARK: 打开快手APP
    static func openKuaiShouApp(){
        if let url1 = URL(string: "kwai://") {
            UIApplication.shared.open(url1, options: [:]) { boolValue in
                print("boolValue=",boolValue)
                if !boolValue {
                    kWindow.makeToast("请检查是否安装快手App", position: .center)
                }
            }
        }
        else if let url2 = URL(string: "ksnebula://") {
            UIApplication.shared.open(url2, options: [:]) { boolValue in
                print("boolValue=",boolValue)
                if !boolValue {
                    kWindow.makeToast("请检查是否安装快手App", position: .center)
                }
            }
        }
        else {
            kWindow.makeToast("请检查是否安装快手App", position: .center)
        }
    }

swift"> Utils.openKuaiShouApp()
