4.XCode4.2新特性：
5.XCode4.2数据库访问
1） 创建工程，注意勾选 Core Data Frameworks-负责数据的存储，缓存，内存管理。是模型的图形化管理和持久化框架。其实就是SQLite数据库类的派生类。主要有3个类：
ManagedObjectContext 数据库操作对象
ManagedObject 数据记录对象
ManagedObjectModel
2）没有了models文件夹，取代的是一个后缀是.xcdatamodeld的文件

如果无法保证子类行为的一致性，那么就用委托 If the subClass cann't keep with superClass,use delegate rather than inheritance. 2:屏幕上看到的，都是UIVew Everything you see on Screen is UIView. 3:如果对性能要求高，慎用Interface Build if application's performance is important,be discreet for the interface build. 4:copy是创建，retain是引用 the copy operation is create a new one,but the retain operation is just a reference. 5：alloc需要release,convenient不需要release alloc method need corresponding release method,but convenient method not. 6:加载到NSArray/NSMutableArray里的对象，不需要负责release The objects added to NSArray/NSMutableArray need not to be released. 7:IBOutlet,IBAction为你开启了访问Interface Build中对象的大门 IBOutlet and IBAction open the door to access the objects in Interface build. 8:UIApplicationDelegate负责应用程序的生命周期，而UIViewController负责View的生命周期 UIApplicationDelegate is responsible for the application life cycle,but UIViewController for the UIView. 9:为了程序的健壮性，请尽量实现Delegate的生命周期函数 if you want to develop a robust application,implement the life cycle methods as more as possbile. 10:哥触摸的不是UIEvent,而是NSSet的UIView what you touch on screen is not UIEvent but UIView
