1、去微信开发平台下载 sdk ：https://pay.weixin.qq.com/wiki/doc/api/app.php?chapter=8_5

2、将SDK文件中包含的 libWeChatSDK.a，WXApi.h，WXApiObject.h 三个文件添加到你所建的工程中

3、导入对应的库文件：

SystemConfiguration.framework,libz.dylib,libsqlite3.0.dylib,libc++.dylib。

4、appdelegate里面：

@interface AppDelegate : UIResponder <WXApiDelegate>

{

enum WXScene _scene;

}

//微信支付
#import "WXApi.h"
#import "WXApiObject.h"

注册APPID

商户APP工程中引入微信lib库和头文件，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"];

  #pragma mark - //向微信注册
    
    [WXApi registerApp:APP_ID withDescription:@"demo 2.0"];

#pragma mark -     微信支付 －      －－－－－－

-(void) changeScene:(NSInteger )scene
{
    _scene = (enum WXScene)scene;
}

-(void) onResp:(BaseResp*)resp
{
    NSString *strMsg = [NSString stringWithFormat:@"errcode:%d", resp.errCode];
    NSString *strTitle;
    
    if([resp isKindOfClass:[SendMessageToWXResp class]])
    {
        strTitle = [NSString stringWithFormat:@"发送媒体消息结果"];
    }
    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
        strTitle = [NSString stringWithFormat:@"支付结果"];
        
        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！"];
           // 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;
        }
    }
    UIAlertView *alert = [[UIAlertView alloc] initWithTitle:strTitle message:strMsg delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil, nil];
    [alert show];
    
}


- (BOOL)application:(UIApplication *)application handleOpenURL:(NSURL *)url
{
    return  [WXApi handleOpenURL:url delegate:self];
}

5、

调起支付接口：

  if (![WXApi isWXAppInstalled]) {
            [PTHudView showOnlyText:@"请先安装微信!" dismiss:YES];
            return;
        }
        
        
        NSMutableDictionary * params = [NSMutableDictionary dictionary];
        params[@"SIMILAR_ID"] = @"15c0992d0db44bdd9170e02a98aaf9c5";
        [HWHttpTool post:[NSString stringWithFormat:@"http://12xxxxxxxapp/pay/wxOrder"] params:params success:^(id json) {
       
            NSString * stamp = [json objectForKey:@"timestamp"];
            //调起微信支付
            PayReq* req             = [[PayReq alloc] init];
            req.openID              = [json objectForKey:@"appid"];
            req.partnerId           = [json objectForKey:@"partnerid"];
            req.prepayId            = [json objectForKey:@"prepayid"];
            req.nonceStr            = [json objectForKey:@"noncestr"];
            req.timeStamp           = stamp.intValue;
            req.package             = [json objectForKey:@"package"];
            req.sign                = [json objectForKey:@"sign"];
            
            [WXApi sendReq:req];
            
        } failure:^(NSError *error) {
            
        }];

if(self.weixindic ==nil || ![[self.weixindicobjectForKey:@"status"]isEqualToString:@"success"]){
