微信支付的开发
前言：之前听说过微信支付有很多坑，其实没有想象的那么坑，整体感觉很容易上手，按照它的流程来不会有错！PS:官方的流程看的TMD烦，好啦，废话有点多，进入开发。（ps:每个微信的版本一直都在更新，这是2015/6/1给你们做的标记
1. 导入微信支付库
微信开放平台新增了微信模块用户统计功能，便于开发者统计微信功能模块的用户使用和活跃情况。开发者需要在工程中链接上:SystemConfiguration.framework,libz.dylib,libsqlite3.0.dylib。
最重要的时这个库：libc++.dylib《ps:官方的文档没说，艹！》
2.在AppDelegate中导入：
（1）#import "WXApi.h"
#import "WXApiObject.h"
遵守WXApiDelegate
在这个方法里注册
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
[WXApi registerApp:WXAppId withDescription:@"yishuPayDes"];
}
（2）跳转处理
- (BOOL)application:(UIApplication *)application
openURL:(NSURL *)url
sourceApplication:(NSString *)sourceApplication
annotation:(id)annotation
{
NSLog(@"跳转到URL schema中配置的地址-->%@",url);//跳转到URL schema中配置的地址
if ([UMSocialSnsService handleOpenURL:url]) {
return [UMSocialSnsService handleOpenURL:url];
}else{
return [WXApi handleOpenURL:url delegate:self];
}
}
（3）回调方法
-(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);
NSNotification *notification = [NSNotification notificationWithName:ORDER_PAY_NOTIFICATION object:@"success"];
[[NSNotificationCenter defaultCenter] postNotification:notification];
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);
NSNotification *notification = [NSNotification notificationWithName:ORDER_PAY_NOTIFICATION object:@"fail"];
[[NSNotificationCenter defaultCenter] postNotification:notification];
break;
}
}
}
// UIAlertView *alert = [[UIAlertView alloc] initWithTitle:strTitle message:strMsg delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil, nil];
// [alert show];
}
说明：这里掌拍艺术App的调试和真机，建议把通知的东西注销，打开alert,方便测试，便于检查回调错误信息，如果你够牛，可以无视，代码难看，见谅，但是人很帅，哈哈！
（4）.接下来在需要支付的界面做这些事：
//监听通知
- (void)viewWillAppear:(BOOL)animated{
[self requestDownloadData];
if([WXApi isWXAppInstalled]) // 判断 用户是否安装微信
{
[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(getOrderPayResult:) name:ORDER_PAY_NOTIFICATION object:nil];//监听一个通知
}
[super viewWillAppear:animated];
}
/*ORDER_PAY_NOTIFICATION*/这个写个宏，全局里写，怎么写？建.h文件！
//移除通知
- (void)viewWillDisappear:(BOOL)animated{
[[NSNotificationCenter defaultCenter]removeObserver:self];
}
开始支付-----→终于等到你，还好没放弃！
1. 预备工作，(1)我这里封装了下载类AF(自己感觉比较方便，亲们自己写下载就好了，因为我们公司的网络数据就那么几种)主要用于请求后台服务器已经做好的数据，请求下来的参数给微信，用于支付！(2)获取每台设备的IP地址,(3)HUD是啥，大家都用过，不说了（ps:HUD特效，自己定义看看那种效果好!）(4)后台做了什么：http://wxpay.weixin.qq.com/pub_v2/app/app_pay.php这个地址给后台参考下，需要的参数都在上面移动端不需要写，如果你要写，我不拦你…哈哈，当练手吧!
