前言:
iPhone

是个极具艺术性的平台,相信大家在开发过程中一定有很多感触,希望能写出来一起交流,所以开了这个帖子,以后还会维护。

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


UIView

what you touch on screen is not UIEvent but UIView
