针对需要在IOS手机上接入原生微信支付场景，调用微信进行支付。如图：
登录，进入账号中心，进行开发者资质认证。
认证完成后，进入管理中心，新建移动应用。填写应用资料，其中android版应用签名可通过扫码安装温馨提供的应用获得，详细参考微信文档。创建完成后点击查看，申请开通微信支付。一切准备就绪！

3.IOS客户端开发
导入微信开发包
添加URL Types
在AppDelegate.m中注册应用
[objc]view plaincopy
print?
#import"AppDelegate.h"
#import"XSTabBarViewController.h"
#import
#import"WXApi.h"
@interfaceAppDelegate()
@end
@implementationAppDelegate
-(BOOL)application:(UIApplication*)applicationdidFinishLaunchingWithOptions:(NSDictionary*)launchOptions{
//Overridepointforcustomizationafterapplicationlaunch.
//[NSThreadsleepForTimeInterval:2.0];
//进入主控制器
self.window=[[UIWindowalloc]init];
self.window.frame=[UIScreenmainScreen].bounds;
self.window.rootViewController=[[XSTabBarViewControlleralloc]init];
[self.windowmakeKeyAndVisible];
//向微信注册应用。
[WXApiregisterApp:@"wxfb96c2a9b531be26"];
returnYES;
}
-(void)onResp:(BaseResp*)resp
{
//NSLog(@"----onResp%@",resp);
/*
ErrCodeERR_OK=0(用户同意)
ERR_AUTH_DENIED=-4(用户拒绝授权)
ERR_USER_CANCEL=-2(用户取消)
code用户换取access_token的code，仅在ErrCode为0时有效
state第三方程序发送时用来标识其请求的唯一性的标志，由第三方程序调用sendReq时传入，由微信终端回传，state字符串长度不能超过1K
lang微信客户端当前语言
country微信用户当前国家信息
*/
if([respisKindOfClass:[SendAuthRespclass]])//判断是否为授权请求，否则与微信支付等功能发生冲突
{
SendAuthResp*aresp=(SendAuthResp*)resp;
if(aresp.errCode==0)
{
//NSLog(@"code%@",aresp.code);
[[NSNotificationCenterdefaultCenter]postNotificationName:@"wechatDidLoginNotification"object:selfuserInfo:@{@"code":aresp.code}];
}
}else{//支付请求回调
//支付返回结果，实际支付结果需要去微信服务器端查询
NSString*strMsg=[NSStringstringWithFormat:@"支付结果"];
NSString*respcode=@"0";
switch(resp.errCode){
caseWXSuccess:
strMsg=@"支付结果：成功!";
//NSLog(@"支付成功-PaySuccess，retcode=%d",resp.errCode);
respcode=@"1";
break;
default:
strMsg=[NSStringstringWithFormat:@"支付结果：失败!retcode=%d,retstr=%@",resp.errCode,resp.errStr];
//NSLog(@"错误，retcode=%d,retstr=%@",resp.errCode,resp.errStr);
respcode=@"0";
break;
}
[[NSNotificationCenterdefaultCenter]postNotificationName:@"wechatDidPayNotification"object:selfuserInfo:@{@"respcode":respcode}];
}
}
//iOS9.0之前的处理方法不保证正确,如有错误还望指正
-(BOOL)application:(UIApplication*)applicationopenURL:(NSURL*)urlsourceApplication:(NSString*)sourceApplicationannotation:(id)annotation
{
NSLog(@"iOS9.0之前");
return[selfapplicationOpenURL:url];
}
-(BOOL)application:(UIApplication*)appopenURL:(NSURL*)urloptions:(NSDictionary*)options{
NSLog(@"iOS9.0之后");
return[selfapplicationOpenURL:url];
}
-(BOOL)applicationOpenURL:(NSURL*)url
{
if([[urlabsoluteString]rangeOfString:@"wxfb96c2a9b531be26://pay"].location==0){
return[WXApihandleOpenURL:urldelegate:self];
}
if([url.hostisEqualToString:@"safepay"])
{
[[AlipaySDKdefaultService]processOrderWithPaymentResult:urlstandbyCallback:nil];
returnYES;
}
returnYES;
}
}
在需要支付的Controller中接受微信支付通知
[objc]view plaincopy
print?
-(void)viewDidLoad{
[superviewDidLoad];
//接受微信支付通知
[[NSNotificationCenterdefaultCenter]addObserver:selfselector:@selector(wechatDidPayNotification:)name:@"wechatDidPayNotification"object:nil];
}
向服务器端获取统一订单，并拉起微信进行支付
[objc]view plaincopy
print?
-(void)weixinPay
{
NSString*userUrlStr=[NSStringstringWithFormat:@"%@?sid=%@&account=%@&desc=%@",WX_PREPAY_URL,self.student.sid,self.payJinE,self.student.nid];
NSURL*url=[NSURLURLWithString:userUrlStr];
//NSLog(@"userUrlStr=%@",userUrlStr);
NSURLRequest*request=[NSURLRequestrequestWithURL:url];
AFHTTPRequestOperation*operation=[[AFHTTPRequestOperationalloc]initWithRequest:request];
[MBProgressHUDshowMessage:@"跳转中，请稍候"];
[operationsetCompletionBlockWithSuccess:^(AFHTTPRequestOperation*operation,NSDictionary*responseObject){
[MBProgressHUDhideHUD];
//NSLog(@"微信支付的response=%@",operation.responseString);
NSData*JSONData=[operation.responseStringdataUsingEncoding:NSUTF8StringEncoding];
NSDictionary*userDict=[NSJSONSerializationJSONObjectWithData:JSONDataoptions:NSJSONReadingMutableLeaveserror:nil];
//调用微信支付
PayReq*request=[[PayReqalloc]init];
/**商家向财付通申请的商家id*/
request.partnerId=[userDictobjectForKey:@"partnerid"];
/**预支付订单*/
request.prepayId=[userDictobjectForKey:@"prepayid"];
/**商家根据财付通文档填写的数据和签名*/
request.package=[userDictobjectForKey:@"package"];
/**随机串，防重发*/
request.nonceStr=[userDictobjectForKey:@"noncestr"];
/**时间戳，防重发*/
request.timeStamp=[[userDictobjectForKey:@"timestamp"]intValue];
/**商家根据微信开放平台文档对数据做的签名*/
request.sign=[userDictobjectForKey:@"sign"];
self.sign=request.sign;
self.ordnum=[userDictobjectForKey:@"ordnum"];
[WXApisendReq:request];
}failure:^(AFHTTPRequestOperation*operation,NSError*error){
[MBProgressHUDhideHUD];
NSLog(@"发生错误!%@",error);
}];
NSOperationQueue*queue=[[NSOperationQueuealloc]init];
[queueaddOperation:operation];
}
//微信支付结果
-(void)wechatDidPayNotification:(NSNotification*)notification
{
//NSLog(@"wechatDidPayNotification");
NSDictionary*nameDictionary=[notificationuserInfo];
NSString*respcode=[nameDictionaryobjectForKey:@"respcode"];
if([respcodeisEqualToString:@"1"]){
//支付成功，更新用户信息
[selfpayDidFinish];
}else{
//支付失败，
[selfsetupAlertControllerWithTitle:@"微信支付结果"messge:@"本次支付未完成，您可以稍后重试!"confirm:@"好的"];
}
