iPhone開發經典語錄集錦

前言：iPhone是個極具藝術性的平台，相信大家在開發過程中一定有很多感觸，希望能寫出來一起交流，是以開了這個文章，以後還會維護。

如果大家和我一樣有感觸的話，可以跟在文章下面，最好簡短并附上中英文：）

1：如果無法保證子類行為的一緻性，那麼就用委托 If the subClass cann't keep with superClass,use delegate rather than inheritance.

2:螢幕上看到的，都是UIVew Everything you see on Screen is UIView.

3:如果對性能要求高，慎用Interface Build if application's performance is important,be discreet for the interface build.

4:copy是建立，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:加載到NSArray/NSMutableArray裡的對象，不需要負責release The objects added to NSArray/NSMutableArray need not to be released.

7:IBOutlet,IBAction為你開啟了通路Interface Build中對象的大門 IBOutlet and IBAction open the door to access the objects in Interface build.

8:UIApplicationDelegate負責應用程式的生命周期，而UIViewController負責View的生命周期 UIApplicationDelegate is responsible for the application life cycle,but UIViewController for the UIView.

9:為了程式的健壯性，請盡量實作Delegate的生命周期函數 if you want to develop a robust application,implement the life cycle methods as more as possbile.

10:哥觸摸的不是UIEvent,而是NSSet的UIView what you touch on screen is not UIEvent but UIView
