Iphone iCloud和CoreData
我正在尝试在iOS应用程序中使用iCloud。我的应用程序可以在单个设备上运行，但当我添加iCloud时，什么也没发生。我浏览了整个网络，只找到了一个我不理解的例子。我的应用程序是iOS 5.0，使用核心数据存储页面。下面是我的应用程序代理和我的视图，我在其中显示它。很抱歉在iPhone开发方面缺乏相关知识。请提供帮助。 多谢各位Iphone iCloud和CoreData,iphone,objective-c,ipad,core-data,icloud,Iphone,Objective C,Ipad,Core Data,Icloud,我正在尝试在iOS应用程序中使用iCloud。我的应用程序可以在单个设备上运行，但当我添加iCloud时，什么也没发生。我浏览了整个网络，只找到了一个我不理解的例子。我的应用程序是iOS 5.0，使用核心数据存储页面。下面是我的应用程序代理和我的视图，我在其中显示它。很抱歉在iPhone开发方面缺乏相关知识。请提供帮助。 多谢各位 如果有人知道/拥有一个完整的iCloud+CoreData项目，我相信我能找到答案。现在我只是有代码剪贴，我甚至不知道他们是怎么被调用的。。。如果我有一个完整的项目
如果有人知道/拥有一个完整的iCloud+CoreData项目，我相信我能找到答案。现在我只是有代码剪贴，我甚至不知道他们是怎么被调用的。。。如果我有一个完整的项目，我可以逐步完成它，这样我就可以完全理解它是如何工作的 问题是我认为没有调用任何东西来用数据更新视图，我也不相信它会将数据发送到云，但我不知道该调用什么 PageFlipperAppDelegate.h
