RestKit - RKObjectMapping只运行一次

时间：2012-01-30 01:39:23

标签： iphone ios ipad ios5 restkit

我正在使用RestKit iOS软件包，允许用户从他们拥有的帐户中提取信息。下面的代码第一次完美运行。但是，如果我第二次尝试使用不同的用户名和密码，它只会加载第一次映射调用的信息。此外，当第二次发送请求时，它会不合理地快速返回数据，这使我相信它只是使用缓存数据。我已经高低搜索了任何重置restkit（和它的缓存）的方法，但没有一个工作。这是我的代码：

- (void)login {
    RKObjectMapping* mapping = [RKObjectMapping mappingForClass:[MyClass class]];
    [mapping mapKeyPathsToAttributes:
     @"Data.MailboxId", @"MailboxId",
     @"Data.value1", @"Value1",
     @"Data.value2", @"Value2",
     nil];


    [RKObjectManager objectManagerWithBaseURL:@"https://my.site.com"];

    [RKObjectManager sharedManager].client.username = username.text;
    [RKObjectManager sharedManager].client.password = password.text;

    [[RKObjectManager sharedManager] loadObjectsAtResourcePath:@"/api/v1.0/?format=json" objectMapping:mapping delegate:self];
}

这是来自RestKit的日志：

2 个答案:

答案 0 :(得分：1)

答案非常简单。我刚刚在我的请求中添加了以下代码行来强制进行基本的HTTP身份验证，这一切都有效：

[RKObjectManager sharedManager].client.authenticationType = RKRequestAuthenticationTypeHTTPBasic;

答案 1 :(得分：0)

您是否尝试过更改缓存策略？

f.e。

RKClient* client = [RKClient clientWithBaseURL:APP_URL];
client.cachePolicy = RKRequestCachePolicyNone;

尝试一下，看看这是否能解决您的问题（暂时）。
