iPhone开发经典语录集锦

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,usedelegate 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InterfaceBuild

 

if application's performance isimportant,be discreet for the interface build.

 

 

 

 

 

4:copy是创建，retain是引用

 

the copy operation is create a new one,butthe retain operation is just a reference.

 

 

 

 

 

5：alloc需要release,convenient不需要release

 

alloc method need corresponding releasemethod,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/NSMutableArrayneed not to be released.

 

 

 

 

 

7:IBOutlet,IBAction为你开启了访问InterfaceBuild中对象的大门

 

IBOutlet and IBAction open the door toaccess 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 forthe 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 robustapplication,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 butUIView
