TPDelegateMatrioska

It’s base on LBDelegateMatrioska.

This class is a subclass of NSProxy subclass that allows you to have multiple delegate helper objects (instead of the usual 1 to 1 relationship between the delegator and delegate).

TPDelegateMatrioska is thread safe based NSRecursiveLock.

Usage

pod 'TPDelegateMatrioska', '~> 0.0.3'

You can init an TPDelegateMatrioska object with as many delegate objects you want

TPDelegateMatrioska *matrioska = [[TPDelegateMatrioska alloc] initWithDelegates:@[mapClusterDelegate, self]];

or

TPDelegateMatrioska *matrioska = [[TPDelegateMatrioska alloc] init];
[matrioska addDelegate:aDelegate];
...

and the add this object as delegate

obj.delegate = matrioska;

In this way every time the obj calls a delegate this call is forwarded to all the delegates respecting the array sorting.

The proxy object keep a weak reference to all the delegate objects, therefore is your responsibility to keep the objects alive with a strong reference. Anyway, by using an NSPointerArray I’m sure that if a delegate gets deallocated the reference inside the array is nil-ed and therefor doesn’t crash the app.

There are just 2 basic rule and one limitation you have to keep in mind:

  • The proxy will respond YES to the respondToSelector: message if and only if at least one of the provided delegate objects respond YES to the same method.
  • The previous rule apply the same for conformsToProtocol:
  • If the delegate method is non-void returning method only the first delegate (that is able to respond to that method) is called and its return value is returned.

中文说明

因为 LBDelegateMatrioska 不是线程安全的,所以才有了这个库。

为什么没有提交 PR 而是新建一个仓库,因为我发现这个仓库已经太久没有更新过(虽然 也可能是没有更新的必要QAQ)。

具体使用见 DEMO。
