iOS - 芝麻认证

前言、芝麻认证需要后台传给你一个 url，后台去蚂蚁金服上看的文档写的有iOS和安卓要实现的代码！

一、请求接口，返回url

       [self doVerify:jsonDict[@"data"][@"biz_no"]];

二、相关代码

    #pragma mark - 芝麻认证
    - (void)doVerify:(NSString *)url {
        NSString *alipayUrl = [NSString stringWithFormat:@"alipays://platformapi/startapp?appId=20000067&url=%@", [self URLEncodedStringWithUrl:url]];
        if ([self canOpenAlipay]) {
            [[UIApplication sharedApplication] openURL:[NSURL URLWithString:alipayUrl] options:@{} completionHandler:nil];
        } else {
            UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"" message:@"是否下载并安装支付宝完成认证?" delegate:self cancelButtonTitle:@"取消" otherButtonTitles:@"好的", nil];
            [alertView show];
        }
    }
    
    -(NSString *)URLEncodedStringWithUrl:(NSString *)url {
        NSString *encodedString = (NSString *)CFBridgingRelease(CFURLCreateStringByAddingPercentEscapes(NULL,(CFStringRef)url,NULL,(CFStringRef) @"!*'();:@&=+$,%#[]|",kCFStringEncodingUTF8));
        return encodedString;
    }
    
    - (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex {
        if (buttonIndex == 1) {
            NSString *appstoreUrl = @"itms-apps://itunes.apple.com/app/id333206289";
            [[UIApplication sharedApplication] openURL:[NSURL URLWithString:appstoreUrl] options:@{} completionHandler:nil];
        }
    }
    
    - (BOOL)canOpenAlipay {
        return [[UIApplication sharedApplication] canOpenURL:[NSURL URLWithString:@"alipays://"]];
    }

三、认证成功或者失败，返回自己app回调 需要对接支付宝相关流程
