如果大家和我一样有感触的话，可以跟在帖子下面，最好简短并附上中英文：）

1：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
