iPhone开发经典语录集锦

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.



累了,去 读意优休息一下下,QQ空间,美文,非主流,网络日记,搞笑短信,祝福短信,热门短信,有意思啊



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
