uliwitness / uliproxies

A few classes that forward messages to another object in some way, but modify thread or timing.

What is it

A few helper classes that can be used as proxies for other objects. This usually involves some sort of threading or time-delay of messages.

What is what

UKMainThreadProxy - Use this on an object to send a message on one threading and have it automatically packaged up and sent on the main thread. This is useful for cases for messages that take more than 2 or non-object parameters.

UKPushbackMessenger - This object coalesces a message sent to it transparently (It does not look at message parameters, only the method name). And sends it if no additional identical message comes in after a specified delay. This is useful to e.g. perform a slightly expensive operation as soon as the user pauses in typing, but not on every character.

UKThreadMessenger - Executes all messages it is sent on a dedicated thread. This is bad, old, busted code. Use NSOperationQueue and blocks instead.
