Swift调用微信支付宝SDK(Swift4.0)

159 阅读 0 评论 105 点赞

我是靠谱客的博主冷傲航空，这篇文章主要介绍Swift调用微信支付宝SDK(Swift4.0)，现在分享给大家，希望可以做个参考。

怎么集成SDK自行百度

　1.第一步在程序入口注册微信 (支付宝不需要)

复制代码

1
2
3
4
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
//向微信终端程序注册第三方应用
WXApi.registerApp(WX_APPID)
}

　 2.微信支付管理类客户端只负责调用(支付信息什么的都是服务器完成的)

复制代码

import UIKit
//微信appid
let WX_APPID=""
//AppSecret
let SECRET=""
//微信
class WXApiManager:NSObject,WXApiDelegate {
static let shared = WXApiManager()
// 用于弹出警报视图，显示成功或失败的信息()
private weak var sender:BaseViewController! //(UIViewController)
// 支付成功的闭包
private var paySuccessClosure: (() -> Void)?
// 支付失败的闭包
private var payFailClosure: (() -> Void)?
//登录成功
private var loginSuccessClosure:((_ code:String) -> Void)?
//登录失败
private var loginFailClosure:(() -> Void)?
// 外部用这个方法调起微信支付

func payAlertController(_ sender:BaseViewController,
request:PayReq,
paySuccess: @escaping () -> Void,
payFail:@escaping () -> Void) {
// sender 是调用这个方法的控制器，
// 用于提示用户微信支付结果，可以根据自己需求是否要此参数。
self.sender = sender
self.paySuccessClosure = paySuccess
self.payFailClosure = payFail
if checkWXInstallAndSupport(){//检查用户是否安装微信

WXApi.send(request)
}
}
//外部用这个方法调起微信登录
func login(_ sender:BaseViewController,loginSuccess: @escaping ( _ code:String) -> Void,
loginFail:@escaping () -> Void){
// sender 是调用这个方法的控制器，
// 用于提示用户微信支付结果，可以根据自己需求是否要此参数。
self.sender = sender
self.loginSuccessClosure = loginSuccess
self.loginFailClosure = loginFail
if checkWXInstallAndSupport(){
let req=SendAuthReq()
req.scope="snsapi_userinfo"
req.state="app"
WXApi.send(req)
}
}
}
extension WXApiManager {
func onResp(_ resp: BaseResp!) {
if resp is PayResp {//支付
if resp.errCode == 0 {
self.paySuccessClosure?()
}else{
self.payFailClosure?()
}
}else if resp is SendAuthResp{//登录结果
let authResp = resp as! SendAuthResp
var strMsg: String
if authResp.errCode == 0{
strMsg="微信授权成功"
}else{
switch authResp.errCode{
case -4:
strMsg="您拒绝使用微信登录"
break
case -2:
strMsg="您取消了微信登录"
break
default:
strMsg="微信登录失败"
break
}
}
UIAlertController.showAlertYes(sender, title: "授权结果", message: strMsg, okButtonTitle:"确定", okHandler: { (alert) in
if authResp.errCode == 0 {
self.loginSuccessClosure?(authResp.code)
}else{
self.loginFailClosure?()
}
})
}
}
}
extension WXApiManager {
// 检查用户是否已经安装微信并且有支付功能
private func checkWXInstallAndSupport() -> Bool {
if !WXApi.isWXAppInstalled() {
///这里的弹窗是我写的扩展方法
UIAlertController.showAlertYes(sender,title:"", message: "微信未安装", okButtonTitle:"确定")
return false
}
if !WXApi.isWXAppSupport() {
///这里的弹窗是我写的扩展方法
UIAlertController.showAlertYes(sender,title:"", message: "当前微信版本不支持支付", okButtonTitle:"确定")
return false
}
return true
}
}

3. 支付宝管理类客户端只负责调用(支付信息什么的都是服务器完成的)

复制代码

// MARK: - 支付回调
extension AppDelegate{
// iOS 8 及以下请用这个
func application(_ application: UIApplication, open url: URL, sourceApplication: String?, annotation: Any) -> Bool {
if url.host == "safepay"{//支付宝
//支付回调
AlipaySDK.defaultService().processOrder(withPaymentResult: url, standbyCallback:{ (resultDic) in
if resultDic != nil{
AliPayManager.shared.showResult(result:resultDic! as NSDictionary)
}
})
//授权回调
AlipaySDK.defaultService().processAuth_V2Result(url, standbyCallback: { (resultDic) in
if resultDic != nil{
AliPayManager.shared.showAuth_V2Result(result:resultDic! as NSDictionary)
}
})
return true
}else{//微信
return WXApi.handleOpen(url, delegate:WXApiManager.shared)
}
}
// iOS 9 以上请用这个
func application(_ app: UIApplication, open url: URL, options: [UIApplicationOpenURLOptionsKey : Any]) -> Bool {
if url.host == "safepay"{//支付宝
//支付回调
AlipaySDK.defaultService().processOrder(withPaymentResult: url, standbyCallback:{ (resultDic) in
if resultDic != nil{
AliPayManager.shared.showResult(result:resultDic! as NSDictionary)
}
})
//授权回调
AlipaySDK.defaultService().processAuth_V2Result(url, standbyCallback: { (resultDic) in
if resultDic != nil{
AliPayManager.shared.showAuth_V2Result(result:resultDic! as NSDictionary)
}
})
return true
}else{//微信
