Izeni's Common iOS Code http://www.izeni.com/

Usage

This project contains several miscellaneous utilities.

IzeniBroadcast

• Easier to use than NSNotificationCenter
• Objective-C and Swift support
• Automatic removal of listeners upon dealloc; no need to call removeObserver(self)
• Events are identified by UUIDs, which are less likely to collide than user-defined keys
• Events are delivered on the main thread, making GUI updates worry-free
• Events are delivered asynchronously to guarantee correctness, but there is a synchronous option available for those corner cases

class LoginService {
    static let userDidLogout = NSUUID() // This is the broadcast ID
    static var userID: String?
    
    class func logout() {
        ...
        
        // Will call method on LocationTracker and any other monitoring instances.
        Broadcast.emit(userDidLogout, value: userID) // Async, main thread delivery
    }
}
...
class LocationTracker: NSObject {
    static let singleton = LocationTracker()
    static func start() {
        singleton // static let vars are lazy instantiated; this initializes the singleton
    }
    
    init() {
        ...
        // The selector must be an instance method, as class/static functions aren't supported.
        monitorBroadcast(LoginService.userDidLogout, selector: "stop")
    }
    
    func stop() {
        ...
    }
