Question

我正在尝试使用触控板手势和普通鼠标事件将工作的IOS应用程序推广到Mac OSX。

简单的鼠标按下和鼠标拖动工作正常，但更相关的scrollWheel和触控板手势无法执行。

从IOS我知道我的场景需要为手势识别器声明一个委托协议，但在OSX上，这不应该是正常的NSReceiver行为吗？

我确实尝试了所有旧提示，包括使用触控板的系统偏好设置，到目前为止还没有成功。

如果有人知道触控板的Xcode示例项目，那么链接也会很棒。

#if TARGET_OS_IPHONE
@interface MAJMainScene() <UIGestureRecognizerDelegate>
#else
@interface MAJMainScene()
#endif


#if TARGET_OS_IPHONE
...
#else
#pragma mark OSX Event Handling
- (void)mouseDown:(NSEvent *)theEvent {
   NSLog(@"mouseDown");    //this method is called
}

- (BOOL)acceptsFirstResponder {
   return YES;   // debug breakpoint never gets called
}

//reading apples documentation, the following method shouldn't be necessary for high-level trackpad gestures, I tried anyway.
- (BOOL)setAcceptsTouchEvents {
    return YES;  // debug breakpoint never gets called
}

- (void)scrollWheel:(NSEvent *)theEvent{
     NSLog(@"Scroll");    //this method is NOT called
 }

- (void)magnifyWithEvent:(NSEvent *)event {
    NSLog (@"Magnification value is %f", [event magnification]);  //NOT called
}

- (void)rotateWithEvent:(NSEvent *)event {
    NSLog(@"rotate");     //NOT called
}

- (void)swipeWithEvent:(NSEvent *)event {
    NSLog(@"swipe");    //NOT called
}

我刚刚在Detect scroll wheel movement and direction

回答了类似的问题

在您的情况下，您可以将所有其他事件转发到您的场景，如下所示：

@implementation SKView(ScrollTouchForwarding)

- (void)scrollWheel:(NSEvent *)event {
    [self.scene scrollWheel:event];
}

- (void)magnifyWithEvent:(NSEvent *)event {
    [self.scene magnifyWithEvent:event];
}

- (void)rotateWithEvent:(NSEvent *)event {
    [self.scene rotateWithEvent:event];
}

- (void)swipeWithEvent:(NSEvent *)event {
    [self.scene swipeWithEvent:event];
}
