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 的 UIView what you touch on screen is not UIEvent but UIView |
