class WeakObjectBridge : NSObject {
weak var weakObject : AnyObject?
override init() {
super.init()
}
init(object:AnyObject?) {
super.init()
weakObject = object
}
}
操作代理
func operatDelegate(cb: @escaping (_ delegate:AnyObject?) -> ()){
for weakObjectBridge in self.delegateBridges {
DispatchQueue.main.async {
cb(weakObjectBridge.weakObject)
}
}
}
具体调用
func action() {
operatDelegate { (delegate) in
if let myDelegate = delegate as? SomeManagerDelegate {
myDelegate.callBack()
myDelegate.callback?(msg: ["msg":"hello world!"])
}
}
}
