在swift中同时用代理和block(closure)回调

importUIKit
@objcprotocolDetailedViewControllerDelegate {
	@objcoptionalfuncchangeValue (value:Int) ->Void;
}
classDetailedViewController:UIViewController{
	var_title:String?
	vardelegate:DetailedViewControllerDelegate?
	varcount:Int=0
	
	varchangeBlock:((Int) -> ())?
	
	overridefuncviewDidLoad() {
	super.viewDidLoad()
	navigationItem.title=_title
	self.view.backgroundColor=UIColor.brown
	
	weakvarweakSelf =self
	letbtn =CGButton.shendInstance().createButton(frame:CGRect(), bgColor:UIColor.red, title:"按钮", superView:self.view) { (action)in
		weakSelf?.count+=1
		letcout = weakSelf?.count
		// Block回调
		if(weakSelf?.changeBlock! !=nil) {
			weakSelf?.changeBlock!(cout!)
		}
		
		// 代理回调
		if((weakSelf?.delegate?.changeValue) !=nil) {
			weakSelf?.delegate?.changeValue!(value: cout!)
		}
	}
	
	}
	
	funcchangeValue(value:@escaping(Int) -> ()) ->Void{
		self.changeBlock= value
	}
}

moiveView.clickdidSelectItemAt{ (collection, indexPath)in
	letdataModel =self._movieView.dataSource[indexPath.item]as!MovieModel
	letDetailedVC =DetailedViewController()
	DetailedVC.delegate=self
	//Block的回调
	DetailedVC.changeValue(value: { (value)in
		print("blockChange(value)")
	})
	DetailedVC._title= dataModel.titleasString
	self.navigationController!.pushViewController(DetailedVC, animated:true)
}
// delegate的回调
funcchangeValue(value:Int) {
	print("delegateChange(value)")
}
