微信三方登录授权步骤:
一,下载导入SDK
现在微信支持cocopods,直接pod 'WechatOpenSDK'就能一键下载,老司机都懂得,小司机要先集成cocopods,或者按照微信开发文档,手动下载SDK,手动添加框架即可
二,配置 scheme
调用微信后,在微信中返回你的APP就要使用URL scheme,选中“TARGETS”一栏，在“info”标签栏的“URL type“添加“URL scheme”,“URL scheme”为你所注册的应用程序id

三,微信接入
//添加头文件
#import "WXApi.h"
//添加协议 WXApiDelegate
//注册: 在APPDelagate的didFinishLaunchingWithOptions方法中添加
WXApi.registerApp("申请得到的APPID")
//微信登录成功和支付成功回调方法,添加一个通知
/*
WXSuccess = 0, 成功
WXErrCodeCommon = -1, 普通错误类型
WXErrCodeUserCancel = -2, 用户点击取消并返回
WXErrCodeSentFail = -3, 发送失败
WXErrCodeAuthDeny = -4, 授权失败
WXErrCodeUnsupport = -5, 微信不支持
*/
func onResp(_ resp: BaseResp!) {
//微信分享
if resp.errCode == 0 {
let myResp:SendAuthResp = resp as! SendAuthResp
print(myResp.code)
}
}
//MARK:微信登录
func wechatClick() {
if WXApi.isWXAppInstalled() {
let req = SendAuthReq.init()
req.scope = "snsapi_userinfo"
req.state = "com.iuzuan.zsdfw"
WXApi.send(req)
}else{
}
}
//重写AppDelegate的handleOpenURL和openURL方法
func application(_ application: UIApplication, handleOpen url: URL) -> Bool {
WXApi.handleOpen(url, delegate: self)
return true
}
func application(_ application: UIApplication, open url: URL, sourceApplication: String?, annotation: Any) -> Bool {
WXApi.handleOpen(url, delegate: self)
return true
}
//成功回调
func onResp(_ resp: BaseResp!) {
if resp.errCode == 0 {
let myResp:SendAuthResp = resp as! SendAuthResp
print(myResp.code)
//使用通知方法把回调返回到需要的控制器
NotificationCenter.default.addObserver(self, selector: #selector(addNotic(notice:)), name: NSNotification.Name(rawValue: "MyNotice"), object: nil)
///发送通知
NotificationCenter.default.post(name: NSNotification.Name.init(rawValue: "TaskNotice"), object: nil, userInfo: ["str":myResp.code])
}
}
四,授权
//MARK:微信登录点击
func wechatClick() {
if WXApi.isWXAppInstalled() {
let req = SendAuthReq.init()
req.scope = "snsapi_userinfo"
req.state = "com12312312"
WXApi.send(req)
}else{
}
}
//MARK:成功后其它控制器的通知方法
func addNotic(notice:Notification) {
print(notice.userInfo!["str"] as Any)
print("接受到通知")
