Swift object that provides an observable platform for multiple listeners.
Listenable is available through CocoaPods. To install it, simply add the following line to your Podfile:
pod 'Listenable'
And run pod install.
Create a Listenable object either by inheriting or initializing a Listenable typed with a protocol:
class ListenableObject: Listenable<ListenableDelegate> {
// Class
}
You can then add and remove listeners, and update them as required...
Add Listener(s):
add(listener: Listener, priority: ListenerPriority) -> Bool
add(listeners: [Listener], priority: ListenerPriority) -> Void
Remove Listener(s):
remove(listener: Listener) -> Bool
remove(listeners: [Listener]) -> Void
removeAllListeners()
Enumerate & Update Listeners:
updateListeners(updateBlock: (listener: Listener, index: Int) -> Void)
ListenerPriority allows for definition of enumeration priority for a listener; by default the priority parameter is set to .low. The following values can be assigned:
.low (Raw: 0)
.high (Raw: 1000)
.custom (Valid range: 0-1000)
