Ios 如何在swift3中从UIView传递数据UIViewContoller

如何从uiview传递数据uiviewController

我正在使用函数，但它不起作用

协议名为startcalldelegate，函数名为startcall

UIView代码

protocol StartCallDelegate: class {
func startCall(localNickname :String, remoteNickname :String)}

class CardView: UIView {

let managedObjectContext = (UIApplication.shared.delegate as! AppDelegate).persistentContainer.viewContext

weak var delegate: CardViewDelegate?
weak var socketdelegate: StartCallDelegate?

@IBOutlet weak var UserPhoto: UIImageView!
@IBOutlet weak var UserNickName: UILabel!
@IBOutlet weak var UserAge: UILabel!
@IBOutlet weak var UserPeople: UILabel!

var localNickname: String = ""
var remoteNickname: String = ""

@IBAction func SendMessage(_ sender: Any) {
    print("SendMessage")

    //print(localNickName)
    //print(UserNickName.text!)
}

@IBAction func SendVideoCall(_ sender: Any) {
    print("SendVideoCall")

    let entityDescription = NSEntityDescription.entity(forEntityName: "Profile", in: managedObjectContext)
    let request = NSFetchRequest<NSFetchRequestResult>()
    request.entity = entityDescription

    do {
        let objects = try managedObjectContext.fetch(request)

        if objects.count > 0 {
            let match = objects[0] as! NSManagedObject
            localNickname = match.value(forKey: "nick") as! String

        } else {
            print("Nothing founded")
        }
    } catch {
        print("error")
    }

    remoteNickname = UserNickName.text!

    socketdelegate?.startCall(localNickname: localNickname, remoteNickname: remoteNickname)
    delegate?.VideoChatSegue()

}

startCall func不工作

您需要在viewcontroller的ViewDidLoad中定义委托

 let objOardView = CardView() // this is only test purpose
 objOardView.socketdelegate = self

您在何处创建此

卡片视图的对象？@leeyuno bcoz我猜您的委托为零。@NiravD OtherViewController@leeyuno哪个控制器？在您的问题中添加该控制器以及该控制器与此ViewController的关系？在ViewController中添加此代码，但不起作用。。T^T您是否在控制器中声明了CardView？是的，在ViewController中声明了CardView您是否可以将其添加到注释中？
 let objOardView = CardView() // this is only test purpose
 objOardView.socketdelegate = self
