iOS-보기를 통해 모든 터치 전달

iOS-보기를 통해 모든 터치 전달

---

다른 많은보기 위에 오버레이 된보기가 있습니다. 나는 화면에서 몇 가지 터치를 감지하기 위해 Overaly를 사용하고 있지만 그 외에는 뷰가 스크롤 뷰와 같은 다른 뷰의 동작을 멈추고 싶지 않습니다. 모든 터치를 전달하려면 어떻게해야합니까? 이 오버레이 뷰? UIView의 일부입니다.

---

오버레이보기에서 아래보기로 터치를 전달하려면 UIView에서 다음 메소드를 구현하십시오.

목표 -C :

- (BOOL)pointInside:(CGPoint)point withEvent:(UIEvent *)event {
    NSLog(@"Passing all touches to the next view (if any), in the view stack.");
    return NO;
}

빠른:

override func point(inside point: CGPoint, with event: UIEvent?) -> Bool {
    print("Passing all touches to the next view (if any), in the view stack.")
    return false
}

---

사용자 상호 작용을 비활성화하는 것만으로도 충분했습니다!

목표 -C :

myWebView.userInteractionEnabled = NO;

빠른:

myWebView.isUserInteractionEnabled = false

이것은 오래된 스레드이지만 검색시 나왔으므로 2c를 추가 할 것이라고 생각했습니다. 하위보기가있는 덮는 UIView가 있고 하위보기 중 하나에 닿는 터치 만 가로 채기를 원하므로 PixelCloudSt의 답변을 다음과 같이 수정했습니다.

-(BOOL)pointInside:(CGPoint)point withEvent:(UIEvent *)event
{
    for (UIView* subview in self.subviews ) {
        if ( [subview hitTest:[self convertPoint:point toView:subview] withEvent:event] != nil ) {
            return YES;
        }
    }
    return NO;
}

@fresidue 답변의 개선 된 버전. 이 UIView서브 클래스는 서브 뷰 외부로 터치를 전달하는 투명한 뷰로 사용할 수 있습니다 . Objective-C의 구현 :

@interface PassthroughView : UIView

@end

@implementation PassthroughView

- (BOOL)pointInside:(CGPoint)point withEvent:(UIEvent *)event
{
    for (UIView *view in self.subviews) {
        if (!view.hidden && [view pointInside:[self convertPoint:point toView:view] withEvent:event]) {
            return YES;
        }
    }
    return NO;
}

@end

그리고 스위프트에서 :

class PassthroughView: UIView {
  override func point(inside point: CGPoint, with event: UIEvent?) -> Bool {
    return subviews.contains(where: {
      !$0.isHidden && $0.point(inside: self.convert(point, to: $0), with: event)
    })
  }
}

---

터치를 전달하려는 뷰가 서브 뷰 / 슈퍼 뷰가 아닌 경우 UIView 서브 클래스에서 다음과 같이 사용자 정의 속성을 설정할 수 있습니다.

@interface SomeViewSubclass : UIView {

    id forwardableTouchee;

}
@property (retain) id forwardableTouchee;

당신의 .m에서 그것을 합성하십시오 :

@synthesize forwardableTouchee;

그런 다음과 같은 UIResponder 메소드에 다음을 포함하십시오.

- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {

    [self.forwardableTouchee touchesBegan:touches withEvent:event];

}

UIView를 인스턴스화 할 때마다 forwardableTouchee 속성을 이벤트를 전달할보기로 설정하십시오.

    SomeViewSubclass *view = [[[SomeViewSubclass alloc] initWithFrame:someRect] autorelease];
    view.forwardableTouchee = someOtherView;

UIStackView와 비슷한 문제가 있었지만 다른보기 일 수 있습니다. 내 구성은 다음과 같습니다.

It's a classical case where I have a container that needed to be placed in the background, with buttons on the side. For layout purposes, I included the buttons in a UIStackView, but now the middle (empty) part of the stackView intercepts touches :-(

What I did is create a subclass of UIStackView with a property defining the subView that should be touchable. Now, any touch on the side buttons (included in the * viewsWithActiveTouch* array) will be given to the buttons, while any touch on the stackview anywhere else than these views won't be intercepted, and therefore passed to whatever is below the stack view.

/** Subclass of UIStackView that does not accept touches, except for specific subviews given in the viewsWithActiveTouch array */
class NoTouchStackView: UIStackView {

  var viewsWithActiveTouch: [UIView]?

  override func hitTest(point: CGPoint, withEvent event: UIEvent?) -> UIView? {

    if let activeViews = viewsWithActiveTouch {
        for view in activeViews {
           if CGRectContainsPoint(view.frame, point) {
                return view

           }
        }
     }
     return nil
   }
}

---

In Swift 5

class ThroughView: UIView {
    override func point(inside point: CGPoint, with event: UIEvent?) -> Bool {
        guard let slideView = subviews.first else {
            return false
        }

        return slideView.hitTest(convert(point, to: slideView), with: event) != nil
    }
}

---

Try something like this...

for (UIView *view in subviews)
  [view touchesBegan:touches withEvent:event];

The code above, in your touchesBegan method for example would pass the touches to all of the subviews of view.

---

As suggested by @PixelCloudStv if you want to throw touched from one view to another but with some additional control over this process - subclass UIView

//header

@interface TouchView : UIView

@property (assign, nonatomic) CGRect activeRect;

@end

//implementation

#import "TouchView.h"

@implementation TouchView

#pragma mark - Ovverride

- (BOOL)pointInside:(CGPoint)point withEvent:(UIEvent *)event
{
    BOOL moveTouch = YES;
    if (CGRectContainsPoint(self.activeRect, point)) {
        moveTouch = NO;
    }
    return moveTouch;
}

@end

After in interfaceBuilder just set class of View to TouchView and set active rect with your rect. Also u can change and implement other logic.
