问题描述
说我创建一个viewController.然后,我想创建另一个与第一个类似的viewController.看起来像是一项继承工作.
Say i create a viewController. Then I want to create another viewController that's like the first one. Looks like a job for inheritance.
但是,originalViewController的许多任务是私有方法,我想最小化公共接口.
However, many of the task of the originalViewController are private methods and I want to minimize public interface.
如果我将这些方法声明为公共方法,那么,实现私有事物私有化的目标就无法实现.
If I declare those methods public then well, the objective of keeping private things private is not achieved.
如果我将这些方法声明为私有,则子类将不知道这些方法.
If I declare those methods private, then the child class do not know those methods.
如果我为子类创建一个特殊的.h文件,那会很尴尬.
If I create a special .h files for the child class, it'll be awkward.
那么,做这种事情的行业标准方法是什么?
So what's the industry standard way of doing this sort of thing anyway?
在C ++中,我们将使用受保护的方法或函数来实现此权利吗?
In C++ we would use protected methods or function to accomplish this right?
更新:
我放
#import "BGGoogleMap+protected.h"
@implementation BGGoogleMap ()
@end
它不起作用.它要求输入标识符.
It doesn't work. It asks for identifier.
推荐答案
除了Catfish_Man建议的内容外,您还可以在类中创建仅子类可以访问的类别. 此处是文档要做到这一点.基本上,您只需为类创建一个新接口,然后在其中放置任何私有方法.像这样:
In addition to what Catfish_Man suggests, you can make categories on your class that only your subclasses have access to. Here are the docs for how to do that. Basically, you just create a new interface for your class and put any private methods in there. Like this:
@interface MyClass (MyClass_Private)
// Method declarations
@end
将这些内容放入Foo_Internal.h中,并将Foo_Internal.h包含在您的子类中,但不要将其公开.
Put those in Foo_Internal.h, and include Foo_Internal.h in your subclasses, but don't make it public.
