微信支付用到的文件
1.首先支持非arc
2.设置URL types
3.AppDelegate
[WXApi registerApp:
@”
wxd930ea5d5a258f4f
“ withDescription:
@”
demo 2.0
“];
return YES;
}
4.微信回调
处理微信通过URL启动App时传递的数据
– (BOOL)application:(UIApplication *)application openURL:(NSURL *)url sourceApplication:(NSString *)sourceApplication annotation:(
id)annotation {
return [WXApi handleOpenURL:url
delegate:self];
}
//
微信回调
– (
void)onResp:(BaseResp *)resp {
//
errCode
switch (resp.errCode) {
case WXSuccess:
//
成功回调
break;
default:
break;
}
}
5.调用微信支付（主要代码，后台签名）
//
调起微信支付
PayReq* req = [[PayReq alloc] init];
req.openID = APPI_ID;
req.partnerId = PARTNER_ID;
req.prepayId = prePayid;
req.nonceStr = nonce_str;
req.timeStamp = now;
req.package = package;
req.sign = sign;
[WXApi safeSendReq:req];
6.如果要在程序签名
