但是现在下来，运行报错

7A6E5B4D93DEE06188BCDC4F60BBBD5C.jpg

解决方案：添加库 CFNetwork.framework libc++.tbd

然后运行，进入app就奔溃

Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[__NSArrayM enqueue:]: unrecognized selector sent to instance 0x60000024ef40'

在buddle Seeting 里面的Other Linker Flags 中添加-ObjC就可以了。

但是点击发起微信支付返回的是支付失败，不管它了，主要看代码就行

微信支付业务流程

chapter8_3_1.png

商户系统和微信支付系统主要交互说明：

步骤1：用户在商户APP中选择商品，提交订单，选择微信支付。

步骤2：商户后台收到用户支付单，调用微信支付统一下单接口。参见【统一下单API】。

步骤3：统一下单接口返回正常的prepay_id，再按签名规范重新生成签名后，将数据传输给APP。参与签名的字段名为appid，partnerid，prepayid，noncestr，timestamp，package。注意：package的值格式为Sign=WXPay

步骤4：商户APP调起微信支付。api参见本章节【app端开发步骤说明】

步骤5：商户后台接收支付通知。api参见【支付结果通知API】

步骤6：商户后台查询支付结果。，api参见【查询订单API】

开始操作

前期准备

1 pod 接入

pod 'WechatOpenSDK'

sdk里包含了微信登陆，微信分享，微信支付

2 设置URL type 添加 URL schme

3 添加白名单

4重写AppDelegate 的handleOpenURL 和openURL方法

功能代码

1注册微信

BOOL res = [WXApi registerApp:kWXAppConfigWeChatAppId];

2实现WXApiDelegate协议两个方法

-(void) onReq:(BaseReq*)req
-(void) onResp:(BaseResp*)resp

如果你的程序要发消息给微信，那么需要调用WXApi里的sendReq函数

2先实现上述回调方法，包含微信登陆 微信分享 微信支付所有功能的回调

#pragma mark - WXApiDelegate

-(void) onReq:(BaseReq*)req{
    
    
}

-(void) onResp:(BaseResp*)resp{
    
    if([resp isKindOfClass:[SendAuthResp class]]) {
        SendAuthResp* authResp = (SendAuthResp*)resp;
        /* Prevent Cross Site Request Forgery */
        NSLog(@"autoResp state:%@  errcode:%d",authResp.state,resp.errCode);
        
        switch (resp.errCode) {
            case WXSuccess:{
                NSLog(@"RESP:code:%@,state:%@\n", authResp.code, authResp.state);

                !_resultBlock?:_resultBlock(WXLoginResultTypeSuccess);
                NSLog(@"微信登陆成功");
#pragma mark 可获取用户信息 ，但是secret我拿不到 官网文档有详细的介绍
               
                }
                break;
            case WXErrCodeAuthDeny:

                !_resultBlock?:_resultBlock(WXLoginResultTypeAuthDeny);
                NSLog(@"微信登录授权失败");
                break;
            case WXErrCodeUserCancel:
                NSLog(@"微信登录用户取消");
                !_resultBlock?:_resultBlock(WXLoginResultTypeCancel);

            default:
                break;
        }
    }
    else if ([resp isKindOfClass:[SendMessageToWXResp class]]) {
        
        NSLog(@"分享后 --- %d %@ %d", resp.errCode, resp.errStr, resp.type);
        if(resp.errCode==0){  // 分享成功
            NSLog(@"分享成功");
            //[[NSNotificationCenter defaultCenter] postNotificationName:@"thirdShare" object:nil userInfo:@{@"isSuccess":@"1"}];
        }else {

            //[[NSNotificationCenter defaultCenter] postNotificationName:@"thirdShare" object:nil userInfo:@{@"isSuccess":@"0"}];
        }
    }
    else if([resp isKindOfClass:[PayResp class]]){
        
        switch (resp.errCode) {
                case WXSuccess:
                //当这里收到支付成功时，一定要请求服务器查询是否支付成功，不要以客户端的返回作为结果判定
                
                NSLog(@"支付成功");
                !_payResultBlock?:_payResultBlock(WXPayResultTypeSuccess);
                break;
                
                case WXErrCodeUserCancel:
                NSLog(@"支付前用户手动取消");
                !_payResultBlock?:_payResultBlock(WXPayResultTypeCancel);
                break;
                
        
                
            default:
                !_payResultBlock?:_payResultBlock(WXPayResultTypeFailure);
