问如何停止3d触摸其中断其他触摸事件？

EN

@interface ViewController () <UIViewControllerPreviewingDelegate>
@property (nonatomic, strong) UILongPressGestureRecognizer *longPress;
For backward compatibility I’ll also add a long press gesture recogniser here. Should our sample app be run on a device without 3D Touch support, at least the preview can be brought up via a long press gesture.

We’ll check if 3D Touch is available using something like the following method. To complete the setup, I’ve also included a custom initialiser for the long press gesture.

    - (void)check3DTouch {

        // register for 3D Touch (if available)
        if (self.traitCollection.forceTouchCapability == UIForceTouchCapabilityAvailable) {

            [self registerForPreviewingWithDelegate:(id)self sourceView:self.view];
            NSLog(@"3D Touch is available! Hurra!");

            // no need for our alternative anymore
            self.longPress.enabled = NO;

        } else {

            NSLog(@"3D Touch is not available on this device. Sniff!");

            // handle a 3D Touch alternative (long gesture recognizer)
            self.longPress.enabled = YES;

            }
    }

    - (UILongPressGestureRecognizer *)longPress {

        if (!_longPress) {
            _longPress = [[UILongPressGestureRecognizer alloc]initWithTarget:self action:@selector(showPeek)];
            [self.view addGestureRecognizer:_longPress];
        }
        return _longPress;
    }
