Small tool for fast implementation of multi-observer pattern in Objective-C

Usage

Given you have a observer protocol (basicly the same as a delegate protocol):

@protocol ObserverProtocol <NSObject>

- (void)somethingDidHappen:(NSString *)message more:(NSInteger)more;

@end

Create an instance of PLXObservers with your delegate protocol:

PLXObservers <ObserverProtocol> *observers = (PLXObservers <ObserverProtocol>*)[[PLXObservers alloc] initWithObserverProtocol:@protocol(ObserverProtocol)];

Add/remove as many observers (implementing your PLXObservers) as you like:

[observers addObserver:myObserver1]
[observers removeObserver:myObserver2]

Calling a ObserverProtocol method on the PLXObservers instance will be forwarded to the registered observers:

[observers somethingDidHappen:@"test" more:123]
