iOS开发微信SDK的集成(分享、支付)


在我们的App中是很经常的会用到微信的两个功能,1就是分享,2就是支付(通常会和支付宝、银联支付放在一起使用),通常接入这种三方的东西,对于移动端来说,过程都比较简单,但是对于后台来说,一般也不是说难,就是步骤多,配置的东西比移动端多(像比如支付过程), 废话不多说,由于我这里的分享只需要做微信的分享,所以过程比较简单,配置什么的就不多说了,自己去看微信支付的UML流程图和微信SDK的配置流程,对于iOS端的代码如下:
首先在工程里面配置白名单:

AppDelegate里面初始化微信SDK:

1
[WXApi registerApp:kWeChatID];

支付or分享代码:

[ShareView shareViewWithCompleteHandel:^(NSInteger index) {
WXMediaMessage * message = [WXMediaMessage message];
message.title = [NSString stringWithFormat:@"%@[%@k-%@k]",rel[@"job_name"],rel[@"salary_min"],rel[@"salary_max"]];
message.description = [NSString stringWithFormat:@"入职快,加薪快,还能赚外快\n%@",rel[@"com_name"]];
[message setThumbImage:image];
WXWebpageObject * webpageObject = [WXWebpageObject object];
webpageObject.webpageUrl = urlString;
message.mediaObject = webpageObject;
SendMessageToWXReq * req = [[SendMessageToWXReq alloc] init];
req.bText = NO;
req.message = message;
req.scene = index == 0 ? WXSceneSession :index == 1 ? WXSceneTimeline:WXSceneFavorite;
[WXApi sendReq:req];
}];

// 支付,note:这里的repsonse是后台生成的支付参数,下订单是请求自己的服务端拿到这些参数:
if ([responese isKindOfClass:[NSDictionary class]]) {
NSDictionary *payParams = (NSDictionary *)responese;
PayReq * req = [[PayReq alloc] init];
req.partnerId = payParams[@"partnerid"];
req.prepayId = payParams[@"prepayid"];
req.nonceStr = payParams[@"noncestr"];
req.timeStamp = [payParams[@"timestamp"] intValue];
req.package = payParams[@"package"];
req.sign = payParams[@"sign"];
[WXApi sendReq:req];
}

[[NSNotificationCenter defaultCenter] postNotificationName:kWeChatPaySucessNotificationName object:self userInfo:@{@"PayResp":resp}];

break;
case -1:
case -2: {

} else if ([resp isKindOfClass:[SendMessageToWXResp class]]) {

SendMessageToWXResp *sendMessageRes = (SendMessageToWXResp *)resp;
if (sendMessageRes.errCode == 0 ) {
[_window.rootViewController alertWithTitle:@"分享成功!" complete:nil];
} else if (sendMessageRes.errCode == WXErrCodeUserCancel) {
[_window.rootViewController alertWithTitle:@"您取消了分享!" complete:nil];
} else {

}
}
}

- (BOOL)application:(UIApplication *)application
openURL:(NSURL *)url
sourceApplication:(NSString *)sourceApplication
annotation:(id)annotation {
if ([url.host isEqualToString:@"safepay"]) {
//跳转支付宝钱包进行支付,处理支付结果
[[AlipaySDK defaultService] processOrderWithPaymentResult:url standbyCallback:^(NSDictionary *resultDic) {
NSLog(@"result = %@",resultDic);
}];
}
return YES;
}

集成起来比较简单,由于这里的支付请求加密参数是放在后台进行的(也理论上是后台做比较安全,为了防止反编译,一般是后台做)App端做的事情相对来来说还是比较少的。
