Swift-Observable

Simple Observable for Swift. It is different from KVO, you can simply add/remove/trigger custom events.

Example

//1. create an Observable entity
var entity = Observable()

//2. add some custom events
//   you need to add event before adding handler
entity.addEvents( "add", "remove" ) 

//3. create a listener
class MyListener {

    func onAddEvent( event:Event, params: AnyObject... ) -> Bool{
        println( event.name )   // add
        return true
    }

    func onRemoveEvent( event:Event, params: AnyObject... ) -> Bool{
        return false
    }
}
var listener = MyListener()

//4. add handler
entity.on( "add", listener.onAddEvent )

//5. trigger an event
entity.fireEvent( "add" )
entity.fireEvent( "add", params: 2, bool, "a" ) //add special data for this event

API

• on(eventName:String, handler:HandlerType, tag:Int=0)
• un(eventName:String, tag:Int)
• addEvents(eventNames:String...)
• addEvent(eventName:String)
• removeEvent(eventName:String)
• clearEvents()
• suspendEvent(eventName:String)
• resumeEvent(eventName:String)
• suspendEvents()
• resumeEvents()
• fireEvent(eventName:String, params:AnyObject...)

Installation

Just copy all the swift files in folder SwiftObservable into your project.

TODO

As the swift is still in beta, it doesn't seem swifty enough, so some feature can't support now, but going to add in the feature.

• EventProtocol
• Customize Event
• Remove Tag
• Optimize Variadic Parameters

Hope this library will help you.
