Issue #70
- Today I was browsing through Suas-iOS and the
subscriptionlinks to life cycle of another object
subscription.linkLifeCycleTo(object: self)
It observes the deinit of another job, interesting approach š , take a look in https://github.com/zendesk/Suas-iOS/blob/master/Sources/StoreDeinitCallback.swift
var deinitCallbackKey = "DEINITCALLBACK_SUAS"
// MARK: Registartion
extension Suas {
static func onObjectDeinit(forObject object: NSObject,
callbackId: String,
callback: @escaping () -> ()) {
let rem = deinitCallback(forObject: object)
rem.callbacks.append(callback)
}
static fileprivate func deinitCallback(forObject object: NSObject) -> DeinitCallback {
if let deinitCallback = objc_getAssociatedObject(object, &deinitCallbackKey) as? DeinitCallback {
return deinitCallback
} else {
let rem = DeinitCallback()
objc_setAssociatedObject(object, &deinitCallbackKey, rem, .OBJC_ASSOCIATION_RETAIN_NONATOMIC)
return rem
}
}
}
@objc fileprivate class DeinitCallback: NSObject {
var callbacks: [() -> ()] = []
deinit {
callbacks.forEach({ $0() })
}
}
