UI에서 제스처 탭을 호출하는 방법 프로그래밍 방식으로 신속하게 보기

UI에서 제스처 탭을 호출하는 방법 프로그래밍 방식으로 신속하게 보기

UI 보기가 있고 탭 제스처를 추가했습니다.

let tap = UITapGestureRecognizer(target: self, action: Selector("handleTap:"))
tap.delegate = self
myView.addGesture(tap)

나는 그것을 테스트 파일에서 프로그래밍 방식으로 부르려고 합니다.

sendActionForEvent

이 기능을 사용하고 있지만 작동하지 않습니다.

myView.sendActionForEvent(UIEvents.touchUpDown)

인스턴스로 전송된 인식할 수 없는 선택기가 표시됩니다.

어떻게 하면 이 문제를 해결할 수 있을까요?

초기화해야 합니다.UITapGestureRecognizer다음과 같은 목표와 행동으로:

let tap = UITapGestureRecognizer(target: self, action: #selector(self.handleTap(_:)))
myView.addGestureRecognizer(tap)

그런 다음 탭 이벤트가 발생할 때마다 호출되는 핸들러를 구현해야 합니다.

@objc func handleTap(_ sender: UITapGestureRecognizer? = nil) {
    // handling code
}

이제 탭 제스처 인식기 이벤트 핸들러를 호출하는 것은 메소드를 호출하는 것만큼이나 쉽습니다.

handleTap()

Swift 3 솔루션을 찾고 있는 모든 사용자를 위한 솔루션

let tap = UITapGestureRecognizer(target: self, action: #selector(self.handleTap(_:)))

view.addGestureRecognizer(tap)

view.isUserInteractionEnabled = true

self.view.addSubview(view)

// function which is triggered when handleTap is called
@objc func handleTap(_ sender: UITapGestureRecognizer) {
     print("Hello World")
  }

Swift 4의 경우:

let tap = UITapGestureRecognizer(target: self, action: #selector(self.handleTap(_:)))

view.addGestureRecognizer(tap)

view.isUserInteractionEnabled = true

self.view.addSubview(view)

// function which is triggered when handleTap is called
@objc func handleTap(_ sender: UITapGestureRecognizer) {
    print("Hello World")
}

Swift 4에서는 트리거된 함수가 Objective-C에서 호출 가능함을 명시적으로 나타내야 하므로 handleTap 함수에 @objc를 추가해야 합니다.

여기에서 @Ali Beadle의 답변을 참조하십시오. Swift 4는 제스처 추가: 오버라이드 vs @objc.

참고 사항 - 보기에서 상호 작용을 활성화하는 것을 잊지 마십시오.

let tap = UITapGestureRecognizer(target: self, action: #selector(handleTap))

view.addGestureRecognizer(tap)

// view.userInteractionEnabled = true

self.view.addSubview(view)

탭 제스처 구현

let tap: UITapGestureRecognizer = UITapGestureRecognizer(target: self, action: "touchHappen") 
view.userInteractionEnabled = true
view.addGestureRecognizer(tap)

탭이 인식되면 이 기능을 호출합니다.

func touchHappen() {
    //Causes the view (or one of its embedded text fields) to resign the first responder status.
    self.view.endEditing(true)
}

Swift 3 +에 대한 업데이트

let tap = UITapGestureRecognizer(target: self, action: #selector(self.touchHappen(_:)))
yourView.addGestureRecognizer(tap)
yourView.userInteractionEnabled = true

func touchHappen(_ sender: UITapGestureRecognizer) {
    print("Hello Dear you are here")
}

단계: 1

@IBOutlet var viewTap: UIView!

단계: 2

var tapGesture = UITapGestureRecognizer()

단계: 3

override func viewDidLoad() {
    super.viewDidLoad()
    // TAP Gesture
    tapGesture = UITapGestureRecognizer(target: self, action: #selector(ViewController.myviewTapped(_:)))
    tapGesture.numberOfTapsRequired = 1
    tapGesture.numberOfTouchesRequired = 1
    viewTap.addGestureRecognizer(tapGesture)
    viewTap.isUserInteractionEnabled = true
}

단계: 4

func myviewTapped(_ sender: UITapGestureRecognizer) {

    if self.viewTap.backgroundColor == UIColor.yellow {
        self.viewTap.backgroundColor = UIColor.green
    }else{
        self.viewTap.backgroundColor = UIColor.yellow
    }
}

1단계: 뷰에 대한 배출구 만들기

@IBOutlet weak var rightViewOutlet: UIView!

2단계: 탭 제스처 정의

var tapGesture = UITapGestureRecognizer()

3단계: ObjC 함수 생성(보기를 누르면 호출됨)

@objc func rightViewTapped(_ recognizer: UIGestureRecognizer) {
    print("Right button is tapped")
}

4단계: viewDidLoad() 내에 다음을 추가합니다.

let rightTap = UITapGestureRecognizer(target: self, action: #selector(ViewController.rightViewTapped(_:)))
    rightViewOutlet.addGestureRecognizer(rightTap)

저는 Xcode 6.4를 swift로 운동했습니다.아래를 참조하십시오.

var view1: UIView!

func assignTapToView1() {          
  let tap = UITapGestureRecognizer(target: self, action: Selector("handleTap"))
  //  tap.delegate = self
  view1.addGestureRecognizer(tap)
  self.view .addSubview(view1)

...
}

func handleTap() {
 print("tap working")
 view1.removeFromSuperview()
 // view1.alpha = 0.1
}

목표 C 코드가 아래에 주어지기를 원한다면,

UITapGestureRecognizer *gesRecognizer = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(handleTap:)]; // Declare the Gesture.
gesRecognizer.delegate = self;
[yourView addGestureRecognizer:gesRecognizer]; // Add Gesture to your view.

// Declare the Gesture Recognizer handler method.

- (void)handleTap:(UITapGestureRecognizer *)gestureRecognizer{
   NSLog(@"Tapped");
}

아니면 아래에 swift code가 주어지기를 원하신다면,

import UIKit
class ViewController: UIViewController {

    @IBOutlet weak var myView: UIView!

    override func viewDidLoad() {
        super.viewDidLoad()

        // Add tap gesture recognizer to view
        let tapGesture = UITapGestureRecognizer(target: self, action: Selector("handleTap:"))
        myView.addGestureRecognizer(tapGesture)
    }

    // this method is called when a tap is recognized
    func handleTap(sender: UITapGestureRecognizer) {

        print("tap")
    }
}

UITapGesture Recognizer는 다음과 같은 대상 및 작업을 사용하여 초기화해야 합니다.

let tap = UITapGestureRecognizer(target: self, action: "handleTap:")
tap.delegate = self
myView.addGestureRecognizer(tap)

그런 다음 탭 이벤트가 발생할 때마다 호출되는 핸들러를 구현해야 합니다.

func handleTap(sender: UITapGestureRecognizer) {
  // handling code
}

Swift 5에서 View에 제스처를 추가하는 가장 간단한 방법은 다음과 같습니다.

import UIKit

class ViewController: UIViewController {

    override func viewDidLoad() {
        super.viewDidLoad()
        addGestures()
    }

    // MARK: Add Gestures to target view
    func addGestures()
    {
        // 1. Single Tap or Touch
        let tapGesture = UITapGestureRecognizer(target: self, action: #selector(self.tapGetstureDetected))
        tapGesture.numberOfTapsRequired = 1
        view.addGestureRecognizer(tapGesture)

        //2. Double Tap
        let doubleTapGesture = UITapGestureRecognizer(target: self, action: #selector(self.doubleTapGestureDetected))
        doubleTapGesture.numberOfTapsRequired = 2
        view.addGestureRecognizer(doubleTapGesture)

        //3. Swipe
        let swipeGesture = UISwipeGestureRecognizer(target: self, action: #selector(self.swipeGetstureDetected))
        view.addGestureRecognizer(swipeGesture)

        //4. Pinch
        let pinchGesture = UIPinchGestureRecognizer(target: self, action: #selector(self.pinchGetstureDetected))
        view.addGestureRecognizer(pinchGesture)

        //5. Long Press
        let longPressGesture = UILongPressGestureRecognizer(target: self, action: #selector(self.longPressGetstureDetected))
        view.addGestureRecognizer(longPressGesture)

        //6. Pan
        let panGesture = UILongPressGestureRecognizer(target: self, action: #selector(self.panGestureDetected))
        view.addGestureRecognizer(panGesture)

    }

    // MARK: Handle Gesture detection
    @objc func swipeGetstureDetected() {
        print("Swipe Gesture detected!!")
    }

    @objc func tapGetstureDetected() {
        print("Touch/Tap Gesture detected!!")
    }

    @objc func pinchGetstureDetected() {
        print("Pinch Gesture detected!!")
    }

    @objc func longPressGetstureDetected() {
        print("Long Press Gesture detected!!")
    }

    @objc func doubleTapGestureDetected() {
        print("Double Tap Gesture detected!!")
    }

    @objc func panGestureDetected()
    {
        print("Pan Gesture detected!!")
    }


    //MARK: Shake Gesture
    override func becomeFirstResponder() -> Bool {
        return true
    }
    override func motionEnded(_ motion: UIEvent.EventSubtype, with event: UIEvent?){
        if motion == .motionShake
        {
            print("Shake Gesture Detected")
        }
    }
}

다음 확장을 시도합니다.

extension UIView {
    
    func  addTapGesture(action : @escaping ()->Void ){
        let tap = MyTapGestureRecognizer(target: self , action: #selector(self.handleTap(_:)))
        tap.action = action
        tap.numberOfTapsRequired = 1
        
        self.addGestureRecognizer(tap)
        self.isUserInteractionEnabled = true
        
    }

    @objc func handleTap(_ sender: MyTapGestureRecognizer) {
        sender.action!()
    }
}

class MyTapGestureRecognizer: UITapGestureRecognizer {
    var action : (()->Void)? = nil
}

그런 다음 사용합니다.

submitBtn.addTapGesture {
     //your code
}

당신은 그것을 세포에도 사용할 수 있습니다.

cell.addTapGesture {
     //your code
}

    let tap = UITapGestureRecognizer(target: self, action: Selector("handleFrontTap:"))
    frontView.addGestureRecognizer(tap)

// Make sure this is not private
func handleFrontTap(gestureRecognizer: UITapGestureRecognizer) {
    print("tap working")
}

스위프트 4

먼저 UITapGestureRecognizer 개체를 만듭니다.

var tapGesture = UITapGestureRecognizer()

두 번째 단계는 UITapGesture Reconizer를 초기화하는 것입니다.사용자 상호 작용을 활성화한 다음 추가합니다.

override func viewDidLoad() {
        super.viewDidLoad()
    tapGesture = UITapGestureRecognizer(target: self, action: #selector(YourViewController.myviewTapped(_:)))
            infosView.isUserInteractionEnabled = true
            infosView.addGestureRecognizer(tapGesture)
view.addSubview(infosView)
}

셋째, 메소드를 만듭니다.

@objc func myviewTapped(_ recognizer: UIGestureRecognizer) {
                print("button is tapped")
            }

저는 Swift 2.2에서 Xcode 7.3.1을 연습했습니다.아래를 참조하십시오.

func addTapGesture() {
    let tap = UITapGestureRecognizer(target: self, action: #selector(MyViewController.handleTap))
    tap.numberOfTapsRequired = 1
    self.myView.addGestureRecognizer(tap)
}

func handleTap() {
    // Your code here...
}

나는 나에게 계속 문제를 일으키는 두 가지 점을 명시하고 싶었습니다.

• 나는 그 안에 제스처 인식기를 만들고 그것을 임대 속성에 저장하고 있었습니다.보기에 이 제스처 기록을 추가할 수 없습니다.초기화 중에 제스처 인식기에 전달된 자체 개체일 수 있으며, 올바르게 구성되지 않았습니다.
• 제스처 인식기를 프레임이 0인 보기에 추가해서는 안 됩니다.제로 프레임으로 모든 보기를 작성한 다음 자동 레이아웃을 사용하여 크기를 조정합니다.자동 레이아웃 엔진에서 보기 크기를 조정한 후 제스처 인식기를 추가해야 합니다.그래서 저는 viewDidAppear에 제스처 인식기를 추가했고 그것들은 작동합니다.

    let strEmail = SAFESTRING(str:  (self.dictEventDetails?.value(forKeyPath: "Email.value_text.email") as! String))

    if !MFMailComposeViewController.canSendMail()
    {
        AppDelegate.sharedInstance().showAlertAction(strTitle: "OK", strMessage: "Mail services are not available") { (success) in
        }
        return
    }
    let composeVC = MFMailComposeViewController()
    composeVC.mailComposeDelegate = self
    composeVC.setToRecipients([strEmail])
    composeVC.setSubject("")
    composeVC.setMessageBody("", isHTML: false)
    self.present(composeVC, animated: true, completion: nil)
}
func mailComposeController(_ controller: MFMailComposeViewController, didFinishWith result: MFMailComposeResult, error: Error?)
{
    controller.dismiss(animated: true, completion: nil)
}

다음과 같은 빠른 코드를 시도합니다(Xcode 6.3.1에서 테스트됨).

    import UIKit

    class KEUITapGesture150427 : UIViewController {
      var _myTap: UITapGestureRecognizer?
      var _myView: UIView?

      override func viewDidLoad() {
        super.viewDidLoad()
        view.backgroundColor = UIColor.whiteColor();

        _myTap = UITapGestureRecognizer(target: self
, action: Selector("_myHandleTap:"))
        _myTap!.numberOfTapsRequired = 1

        _myView = UIView(frame: CGRectMake(100, 200, 100, 100))
        _myView!.backgroundColor=UIColor.blueColor()
        _myView!.layer.cornerRadius = 20
        _myView!.layer.borderWidth = 1
        _myView!.addGestureRecognizer(_myTap!)
        view.addSubview(_myView!)
      }

      func _myHandleTap(sender: UITapGestureRecognizer) {
        if sender.state == .Ended {
          println("_myHandleTap(sender.state == .Ended)")
          sender.view!.backgroundColor
          = UIColor(red: CGFloat(drand48()), green: CGFloat(drand48()), blue: CGFloat(drand48()), alpha: 1.0);
        }
      }
    }

대상은 UIResponder의 하위 클래스일 수 있습니다(Xcode 6.3.1에서 테스트됨).

    import UIKit

    class MyTapTarget  : UIResponder {
      func _myHandleTap2(sender: UITapGestureRecognizer) {
        if sender.state == .Ended {
          println("_myHandleTap2(sender.state == .Ended)")
          sender.view!.backgroundColor
            = UIColor(red: CGFloat(drand48()), green: CGFloat(drand48()), blue: CGFloat(drand48()), alpha: 1.0);
        }
      }
    }

    class KEUITapGesture150427b : UIViewController {
      var _myTap: UITapGestureRecognizer?
      var _myView: UIView?
      var _myTapTarget: MyTapTarget?

      override func viewDidLoad() {
        super.viewDidLoad()
        view.backgroundColor = UIColor.whiteColor();

        _myTapTarget = MyTapTarget()
        _myTap = UITapGestureRecognizer(target: _myTapTarget!
, action: Selector("_myHandleTap2:"))
        _myTap!.numberOfTapsRequired = 1

        _myView = UIView(frame: CGRectMake(100, 200, 100, 100))
        _myView!.backgroundColor=UIColor.blueColor()
        _myView!.layer.cornerRadius = 20
        _myView!.layer.borderWidth = 1
        _myView!.addGestureRecognizer(_myTap!)
        view.addSubview(_myView!)
      }
    }

하는 대신 myView의 UITapGestureRecognizer를할 수 .handleTap 함수를 선택합니다.

제스처 인식기에 직접 액세스하지 않고 보기를 활성화하려는 사용자는 제스처 인식기를 누릅니다.페이지로 돌아갈 때 이전에 탭으로 채워진 버블을 채워야 했습니다.저는 그 버블 태그(거품)들을 추적했습니다...

func fillBubs(bubs: [Int]) {
    for bub in bubs {
        let bubble = view.viewWithTag(bub)
        if bubble == nil {continue}
        for g in bubble!.gestureRecognizers! {
            let tap = g as! UITapGestureRecognizer
            handleBub(tap)
        }
    }
}

@objc func handleBub(_ sender: UITapGestureRecognizer? = nil) {
    let bubble = sender?.view!
    bubble?.layer.backgroundColor = #colorLiteral(red: 0, green: 0, blue: 0, alpha: 1)
}
