Restkit緩存發出的iOS更新保存屬性

我建立了利用restkit對IOS的應用程序。我相信在緩存區有問題。我爲最初的啓動安裝了我的應用程序，以獲取大量數據並使用restkit將其映射到核心數據中。一切工作正常，數據以表格形式顯示。現在，如果我使應用程序進入後臺，然後再次單擊該應用程序以恢復我調用相同的方法來加載數據，但這個時候，我送版本號的服務器以已經改變只取回對象，添加或自上次拉後刪除。這一切都很好地映射，但是當我去顯示這些對象時，我會得到與第一次拉動相同的數據。我相信這可能是清除緩存問題，但我不知道。幫助是感激的。Restkit緩存發出的iOS更新保存屬性

您只需要將其保存在對象加載器委託方法中即可。

- (void)objectLoader:(RKObjectLoader *)objectLoader didLoadObjects:(NSArray *)objects 
{ 
    [[RKObjectManager sharedManager].objectStore.managedObjectContextForCurrentThread  save:nil]; 
}
