ios - swipecellkit - Cómo hacer que una vista de colección responda a gestos de panorámica fuera de su propia vista

Question

Tengo un UICollectionView en mi UIViewController y quiero que responda a los gestos dentro y fuera de UICollectionView . Por defecto, UICollectionView solo responde a los gestos dentro de su propia view pero ¿cómo puedo hacer que responda a golpes fuera de su view ?

Gracias.

Answer 1

Escribí una subclase de vista que logra solo esto:

#import <UIKit/UIKit.h>

@interface TouchForwardingView : UIView

@property (nonatomic, weak) IBOutlet UIResponder *forwardingTarget;

- (instancetype)initWithForwardingTarget:(UIResponder *)forwardingTarget;


@end

#import "TouchForwardingView.h"

@implementation TouchForwardingView

- (instancetype)initWithForwardingTarget:(UIResponder *)forwardingTarget
{
    self = [super init];
    if (self)
    {
        self.forwardingTarget = forwardingTarget;
    }

    return self;
}

- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event
{
    [super touchesBegan:touches withEvent:event];
    [self.forwardingTarget touchesBegan:touches withEvent:event];
}

- (void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event
{
    [super touchesEnded:touches withEvent:event];
    [self.forwardingTarget touchesEnded:touches withEvent:event];
}

- (void)touchesCancelled:(NSSet *)touches withEvent:(UIEvent *)event
{
    [super touchesCancelled:touches withEvent:event];
    [self.forwardingTarget touchesCancelled:touches withEvent:event];
}

- (void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event
{
    [super touchesMoved:touches withEvent:event];
    [self.forwardingTarget touchesMoved:touches withEvent:event];
}

@end

En el generador de interfaz, configure la subvista de la vista que contiene a TouchForwardingView, luego asigne la vista de colección a la propiedad forwardingTarget.

Swift versión de Nailer''s anwer, esto reenviará todos los gestos realizados en viewcontroller a la colección

override func touchesBegan(touches: Set<UITouch>, withEvent event: UIEvent?) {
    collectionView.touchesBegan(touches, withEvent: event)
}
override func touchesEnded(touches: Set<UITouch>, withEvent event: UIEvent?) {
    collectionView.touchesEnded(touches, withEvent: event)
}
override func touchesCancelled(touches: Set<UITouch>?, withEvent event: UIEvent?) {
    collectionView.touchesCancelled(touches, withEvent: event)
}
override func touchesMoved(touches: Set<UITouch>, withEvent event: UIEvent?) {
    collectionView.touchesMoved(touches, withEvent: event)
}

La respuesta de Steven B para Swift 4 :)

override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?) {
    collectionView.touchesBegan(touches, with: event)
}
override func touchesEnded(_ touches: Set<UITouch>, with event: UIEvent?) {
    collectionView.touchesEnded(touches, with: event)
}
override func touchesCancelled(_ touches: Set<UITouch>?, with event: UIEvent?) {
    collectionView.touchesCancelled(touches!, with: event)
}
override func touchesMoved(_ touches: Set<UITouch>, with event: UIEvent?) {
    collectionView.touchesMoved(touches, with: event)
}
