iOS集成微信支付

1，SDK导入

下载官方SDK：下载地址
将SDK文件中包含的 libWeChatSDK.a，WXApi.h，WXApiObject.h，WechatAuthSDK 三个文件添加到你所建的工程中，这里要注意别下错了，之前试过下载的SDK名字都一样，但是就是不能够支付，因为那个SDK只能够支持分享和登录。
添加依赖：
- SystemConfiguration.framework
- libz.tbd
- libsqlite3.tbd
- CoreTelephony.framework
- libc++.tbd
TARGETS-BuildSettings-Build Options: Enable Bitcode 设置为NO
建立PrefixHeader文件，TARGETS-BuildSettings-Apple LLVM7.1-Language :Prefix Headerd, 将建立的pch文件路径填写进去(Xcode右键Show in finder，直接把文件拖到上面，把头路径删除，只留项目名那一级，开头没有/)

PrefixHeader内导入头文件：

 #import <UIKit/UIKit.h> #import "WXApi.h"

TARGETS-Info-URL types添加一项，URL scheme为你注册的应用程序id(例如：wx40xxxxxxxxxxxxxx)，其它为空不填。

AppDelegate中注册

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {    [WXApi registerApp:@"wx40xxxxxxxxxxxxxx" withDescription:@"demo 2.0"];    return YES;}

AppDelegate中设置微信SDK的代理

- (BOOL)application:(UIApplication *)application handleOpenURL:(NSURL *)url {    return  [WXApi handleOpenURL:url delegate:self]; //这里设置任何一个实现了WXApiDelegate协议的对象}- (BOOL)application:(UIApplication *)application openURL:(NSURL *)url sourceApplication:(NSString *)sourceApplication annotation:(id)annotation {    return [WXApi handleOpenURL:url delegate:self]; //这里设置任何一个实现了WXApiDelegate协议的对象}

在微信SDK的代理中处理支付结果

- (void)onResp:(BaseResp *)resp{    if([resp isKindOfClass:[PayResp class]]){        //支付返回结果，实际支付结果需要去微信服务器端查询        NSString *strMsg;        switch (resp.errCode) {            case WXSuccess:                strMsg = @"支付结果：成功！";                NSLog(@"支付成功－PaySuccess，retcode = %d", resp.errCode);                break;            default:                strMsg = [NSString stringWithFormat:@"支付结果：失败！retcode = %d, retstr = %@", resp.errCode,resp.errStr];                NSLog(@"错误，retcode = %d, retstr = %@", resp.errCode,resp.errStr);                break;        }    }}

以上的配置都做完，SDK环境就正式搭好了，其它的在ShareSDK中需要配的诸如白名单什么的，我试了下只导入官方的SDK是不用配的。

2，通过服务器获取订单信息调取支付

    AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];  // 向服务器请求订单信息的参数    NSMutableDictionary *parameters = [NSMutableDictionary dictionary];    parameters[@"token"] = @"app登录帐户的token";    parameters[@"order_id"] = @"要下单的商品id";    [manager POST:@"向服务器获取订单信息的url" parameters:parameters progress:nil success:^(NSURLSessionDataTask * _Nonnull task, id  _Nullable responseObject) {        NSDictionary *dic = responseObject[@"data"];    // 服务器返回的订单数据        // 通过服务器返回的订单数据创建请求参数        PayReq *request = [[PayReq alloc] init];        request.openID = [dic objectForKey:@"appid"];        request.partnerId = [dic objectForKey:@"partenerId"];        request.prepayId = [dic objectForKey:@"prepayId"];        request.package = [dic objectForKey:@"packageValue"];        request.nonceStr = [dic objectForKey:@"nonceStr"];        request.timeStamp = (UInt32)[[dic objectForKey:@"timeStamp"] integerValue];        request.sign = [dic objectForKey:@"sign"];        // 调起微信客户端发起支付        [WXApi sendReq:request];    } failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {    }];

3，本地生成订单信息支付

    NSString *tradeNO = [self generateTradeNO];    NSString *addressIP = [self getIPAddress:YES];    NSString *orderno = [NSString stringWithFormat:@"%ld",time(0)];    DataMD5 *data = [[DataMD5 alloc] initWithAppid:WX_APPID mch_id:MCH_ID nonce_str:tradeNO partner_id:WX_PartnerKey body:@"充值" out_trade_no:orderno total_fee:PRICE spbill_create_ip:addressIP notify_url:NOTIFY_URL trade_type:TRADE_TYPE];    NSString *string = [[data dic] XMLString];    AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];    manager.responseSerializer = [[AFHTTPResponseSerializer alloc] init];    [manager.requestSerializer setValue:@"text/xml; charset=utf-8" forHTTPHeaderField:@"Content-Type"];    [manager.requestSerializer setValue:WXUNIFIEDORDERURL forHTTPHeaderField:@"SOAPAction"];    [manager.requestSerializer setQueryStringSerializationWithBlock:^NSString * _Nonnull(NSURLRequest * _Nonnull request, id  _Nonnull parameters, NSError * _Nullable __autoreleasing * _Nullable error) {        return string;    }];    [manager POST:WXUNIFIEDORDERURL parameters:string progress:nil success:^(NSURLSessionDataTask * _Nonnull task, id  _Nullable responseObject) {        NSString *responseString = [[NSString alloc] initWithData:responseObject encoding:NSUTF8StringEncoding];        NSDictionary *dic = [NSDictionary dictionaryWithXMLString:responseString];        if ([[dic objectForKey:@"result_code"] isEqualToString:@"SUCCESS"] && [[dic objectForKey:@"return_code"] isEqualToString:@"SUCCESS"]) {            PayReq *request = [[PayReq alloc] init];            request.openID = [dic objectForKey:WXAPPID];            request.partnerId = [dic objectForKey:WXMCHID];            request.prepayId = [dic objectForKey:WXPREPAYID];            request.package = @"Sign=WXPay";            request.nonceStr = [dic objectForKey:WXNONCESTR];            NSDate *datenow = [NSDate date];            NSString *timeSp = [NSString stringWithFormat:@"%ld", (long)[datenow timeIntervalSince1970]];            UInt32 timeStamp = [timeSp intValue];            request.timeStamp = timeStamp;            DataMD5 *md5 = [[DataMD5 alloc] init];            request.sign = [md5 createMD5SingForPay:request.openID partnerid:request.partnerId prepayid:request.prepayId package:request.package noncestr:request.nonceStr timestamp:request.timeStamp];            [WXApi sendReq:request];        }    } failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {    }];

本地生成订单支付的处理比较麻烦，具体代码详见Demo

4，Demo下载
