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
? ?3）

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
