1，申请微信支付的功能，获取到开发需要的参数

2，iOS端集成微信支付

2.1项目设置APPID

在URL Scheme中设置

2.2 导入sdk，配置项目，注册APPID

2.2.1 导入demo中的sdk，

2.2.2 还需要倒入demo中的几个系统库

SystemConfiguration.framework

Security.framework

CoreTelephony.framework

Foundation.framework

UIKit.framework

libsqlite3.0.tbd

libz.tbd

2.2.3 调用API前，需要先向微信注册您的APPID，代码如下：

[WXApi registerApp：@"wxd930ea5d5a258f4f" withDescription：@"demo 2.0"];

2.2.4 设置白名单

wechat,wexin

2.3 调起支付

从服务端获取支付需要的参数

PayReq *request = [[[PayReq alloc] init] autorelease];

request.partnerId = @"10000100";

request.prepayId= @"1101000000140415649af9fc314aa427";

request.package = @"Sign=WXPay";

request.nonceStr= @"a462b76e7436e98e0ed6e13c64b4fd1c";

request.timeStamp= @"1397527777";

request.sign= @"582282D72DD2B03AD892830965F428CB16E7A256";

[WXApi sendReq：request];

2.4 支付结果回调处理

-(void)onResp：(BaseResp*)resp{			  if ([respisKindOfClass：[PayRespclass]]){			      PayResp*response=(PayResp*)resp;			      switch(response.errCode){			          caseWXSuccess：                      			//服务器端查询支付通知或查询API返回的结果再提示成功                      			NSlog(@"支付成功");                      	break;                      	default：                      	NSlog(@"支付失败，retcode=%d",resp.errCode);                      	break;                  }                  	}                }

3 测试和dubug

用微信官方提供的http get接口进行测试

@"http://wxpay.weixin.qq.com/pub_v2/app/app_pay.php?plat=ios"

返回的数据格式如下

{

"appid":"wxb4ba3c02aa476ea1",

"partnerid":"1305176001",

"package":"Sign=WXPay",

"noncestr":"60adcb1dcd5d0e8fe903822313810988",

"timestamp":1473724660,

"prepayid":"wx20160913075740396ab1584b0080984714",

"sign":"483F092E7384602E8E7F7ABA3E9F9FC1"

}

预支付订单接口一般由服务器调用，app本地测试时也可以使用

验证签名是否正确

验证签名是否正确可以用微信提供的这个网页，如果本地的签名结果和网页上一致那就完成了。

ios本地调试

本地调试可以使用微信sdk中的payRequsestHandler 类进行，下面的步骤一般不需要进行。协助后台开发调试才会使用。相当于从生成预支付订单到调起微信支付sdk的步骤全部在客户端完成。

//创建支付签名对象    payRequsestHandler *reqHandler = [payRequsestHandler alloc];    //初始化支付签名对象    [reqHandler init:WX_APP_ID mch_id:WX_MCHID];    //设置密钥    [reqHandler setKey:WX_PARTNER_ID];            //价格*100    NSString *priceString=@"1";    NSString *orderName=@"测试标题";        NSString *identifierForVendor = [[[UIDevice currentDevice] identifierForVendor] UUIDString];                //获取到实际调起微信支付的参数后，在app端调起支付    NSMutableDictionary *dict = [reqHandler getPrepayWithOrderName:orderName price:priceString device:identifierForVendor];        NSLog(@"dict%@",dict);    //在payRequestHandle.mm文件里调用该方法        if(dict == nil){        //错误提示        NSString *debug = [reqHandler getDebugifo];                NSLog(@"debug %@",debug);                NSLog(@"%@\n\n",debug);    }else{        NSLog(@"%@\n\n",[reqHandler getDebugifo]);        //[self alert:@"确认" msg:@"下单成功，点击OK后调起支付！"];                NSMutableString *stamp  = [dict objectForKey:@"timestamp"];                //调起微信支付        PayReq* req             = [[PayReq alloc] init];        req.openID              = [dict objectForKey:@"appid"];        req.partnerId           = [dict objectForKey:@"partnerid"];        req.prepayId            = [dict objectForKey:@"prepayid"];        req.nonceStr            = [dict objectForKey:@"noncestr"];        req.timeStamp           = stamp.intValue;        req.package             = [dict objectForKey:@"package"];        req.sign                = [dict objectForKey:@"sign"];                [WXApi sendReq:req];        NSLog(@"appid=%@\npartid=%@\nprepayid=%@\nnoncestr=%@\ntimestamp=%ld\npackage=%@\nsign=%@",req.openID,req.partnerId,req.prepayId,req.nonceStr,(long)req.timeStamp,req.package,req.sign );                            }
