问题描述
我刚创建了一个具有以下属性的iOS类：
I just created an iOS class with the following properties:
@property (nonatomic, strong) NSString* foo;
@property (nonatomic, strong) NSObject* bar;
@property (nonatomic) CGRect fubar;
我没有为这些属性添加任何@synthesize或显式的ivars。然后我进入实现文件并开始创建一个方法如下：
I did not put in any @synthesize or explicit ivars for these properties. I then went into the implementation file and started to create a method as follows:
-(void) add
我将光标留在添加一词的末尾。然后在代码意义上弹出以下方法名称：
I left the cursor at the end of the word "add". The following method names then popped up in code sense:
addBar: (NSSet*) objects
addBarObject: (objectType *) object
addFoo: (NSSet*) objects
addFooObject: (objectType *) object
addFubar: (NSSet*) objects
addFubarObject: (objectType *) object
这些方法是什么？是否有任何文档？
What are these methods? Are there any docs for them?
推荐答案
这是一个类可以实现的访问器方法，以支持可变的键值编码 - 很多关系，
见：
That are accessor methods that a class can implement to support Key-Value Coding for mutable to-many relationships, see Mutable Unordered Accessors in the "Key-Value Coding Programming Guide":
-add< Key>对象：或 -add< Key>：。必须实现这些方法中的至少一种。这些类似于 NSMutableSet 方法
addObject：。
-add<Key>Object: or -add<Key>:. At least one of these methods must be implemented. These are analogous to the NSMutableSet method addObject:.
其他Key-Value编码访问器方法也会发生相同的奇怪自动完成，例如
：
The same "strange" autocompletion happens for other Key-Value coding accessor methods, for example:
- (void)remove...
- (void)intersect...
- (NSUInteger)countOf...
