从ios源码学习代码规范

1.interface的写法

UIView是根据类别来区分不同属性和方法,防止属性过多而分不清楚.

@interface UIView(UIViewHierarchy)

@property(nonatomic,readonly) UIView       *superview;
@property(nonatomic,readonly,copy) NSArray *subviews;
@property(nonatomic,readonly) UIWindow     *window;

- (void)removeFromSuperview;

@interface UIView(UIViewAnimation)

+ (void)beginAnimations:(NSString *)animationID context:(void *)context;  // additional context info passed to will start/did stop selectors. begin/commit can be nested
+ (void)commitAnimations;              

上面的代码把动画和继承分开放置,使代码更加的清晰可读.
