3.IOS用戶端開發

匯入開發包

添加URL Types

在AppDelegate.m中註冊應用

[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];

//進入主控制器

self.window=[[UIWindowalloc]init];

self.window.frame=[UIScreenmainScreen].bounds;

self.window.rootViewController=[[XSTabBarViewControlleralloc]init];

[self.windowmakeKeyAndVisible];

//向註冊應用。

[WXApiregisterApp:@"wxfb96c2a9b531be26"];

returnYES;

}

-(void)onResp:(BaseResp*)resp

{

//NSLog(@"----onResp%@",resp);

/*

ErrCodeERR_OK=0(使用者同意)

ERR_AUTH_DENIED=-4(使用者拒絕授權)

ERR_USER_CANCEL=-2(使用者取消)

code使用者換取access_token的code，僅在ErrCode為0時有效

state第三方程式發送時用來標識其請求的唯一性的標誌，由第三方程式調用sendReq時傳入，由終端回傳，state字串長度不能超過1K

lang用戶端當前語言

country使用者當前國家資訊

*/

if([respisKindOfClass:[SendAuthRespclass]])//判斷是否為授權請求，否則與支付等功能發生衝突

{

SendAuthResp*aresp=(SendAuthResp*)resp;

if(aresp.errCode==0)

{

//NSLog(@"code%@",aresp.code);

[[NSNotificationCenterdefaultCenter]postNotificationName:@"wechatDidLoginNotification"object:selfuserInfo:@{@"code":aresp.code}];

}

}else{//支付請求回調

//支付返回結果，實際支付結果需要去伺服器端查詢

NSString*strMsg=[NSStringstringWithFormat:@"支付結果"];

NSString*respcode=@"0";

switch(resp.errCode){

caseWXSuccess:

strMsg=@"支付結果：成功!";

//NSLog(@"支付成功-PaySuccess，retcode=%d",resp.errCode);

respcode=@"1";

break;

default:

strMsg=[NSStringstringWithFormat:@"支付結果：失敗!retcode=%d,retstr=%@",resp.errCode,resp.errStr];

//NSLog(@"錯誤，retcode=%d,retstr=%@",resp.errCode,resp.errStr);

respcode=@"0";

break;

}

[[NSNotificationCenterdefaultCenter]postNotificationName:@"wechatDidPayNotification"object:selfuserInfo:@{@"respcode":respcode}];

}

}

//iOS9.0之前的處理方法不保證正確,如有錯誤還望指正

-(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之後");

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中接受支付通知

[objc]view plaincopy

print?

-(void)viewDidLoad{

[superviewDidLoad];

//接受支付通知

[[NSNotificationCenterdefaultCenter]addObserver:selfselector:@selector(wechatDidPayNotification:)name:@"wechatDidPayNotification"object:nil];

}

向伺服器端擷取統一訂單，並拉起進行支付

[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:@"跳轉中，請稍候"];

[operationsetCompletionBlockWithSuccess:^(AFHTTPRequestOperation*operation,NSDictionary*responseObject){

[MBProgressHUDhideHUD];

//NSLog(@"支付的response=%@",operation.responseString);

NSData*JSONData=[operation.responseStringdataUsingEncoding:NSUTF8StringEncoding];

NSDictionary*userDict=[NSJSONSerializationJSONObjectWithData:JSONDataoptions:NSJSONReadingMutableLeaveserror:nil];

//調用支付

PayReq*request=[[PayReqalloc]init];

/**商家向財付通申請的商家id*/

request.partnerId=[userDictobjectForKey:@"partnerid"];

/**預支付訂單*/

request.prepayId=[userDictobjectForKey:@"prepayid"];

/**商家根據財付通文檔填寫的資料和簽名*/

request.package=[userDictobjectForKey:@"package"];

/**隨機串，防重發*/

request.nonceStr=[userDictobjectForKey:@"noncestr"];

/**時間戳記，防重發*/

request.timeStamp=[[userDictobjectForKey:@"timestamp"]intValue];

/**商家根據開放平台文檔對資料做的簽名*/

request.sign=[userDictobjectForKey:@"sign"];

self.sign=request.sign;

self.ordnum=[userDictobjectForKey:@"ordnum"];

[WXApisendReq:request];

}failure:^(AFHTTPRequestOperation*operation,NSError*error){

[MBProgressHUDhideHUD];

NSLog(@"發生錯誤!%@",error);

}];

NSOperationQueue*queue=[[NSOperationQueuealloc]init];

[queueaddOperation:operation];

}

//支付結果

-(void)wechatDidPayNotification:(NSNotification*)notification

{

//NSLog(@"wechatDidPayNotification");

NSDictionary*nameDictionary=[notificationuserInfo];

NSString*respcode=[nameDictionaryobjectForKey:@"respcode"];

if([respcodeisEqualToString:@"1"]){

//支付成功，更新使用者資訊

[selfpayDidFinish];

}else{

//支付失敗，

[selfsetupAlertControllerWithTitle:@"支付結果"messge:@"本次支付未完成，您可以稍後重試!"confirm:@"好的"];

}

}
