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
