我有一个NSWindowController,我正在添加相应的ViewControllers。我想在其中一个ViewController中处理触摸事件。我的班级是
window.h中
@interface WindowController : NSWindowController<NSToolbarDelegate>
@property (nonatomic, strong) NSViewController *currentViewController;
@property (assign) IBOutlet NSView *targetView;
@end
Window.m
-(void)addViewController
{
NSViewController *currentController = [[currentControllerClass alloc]initWithNibName:controllerIdentifier bundle:nil];
self.currentViewController = currentController;
[self.targetView addSubview:self.currentViewController.view];
[self.currentViewController.view setFrame: [self.targetView bounds]];
}
-(void) awakeFromNib{
[super awakeFromNib];
[self.window setIgnoresMouseEvents:NO];
[self setToolbarToPracticeView];
}
-(void)mouseDown:(NSEvent *)theEvent
{
NSLog(@"Window > Mouse down");
}
我可以在这里打印mousedown事件。现在我有一个viewController,它是
ViewController.h
@interface ViewController : NSViewController
@end
ViewController.m
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
if (self) {
// Initialization code here.
}
return self;
}
-(void)awakeFromNib
{
[self.view setAcceptsTouchEvents:YES];
}
-(BOOL)acceptsFirstResponder
{
return YES;
}
-(void)mouseDown:(NSEvent *)theEvent
{
NSLog(@"ViewController > mouse down");
}
我想在ViewController中获得mouseDown的控件。我在这里错过了什么吗?
感谢。

创建自定义NSView,然后在其协议中委托mouseDown方法。在ViewController中导入并使用customView并委派其方法。单击视图时会触发mouseDown事件。

不确定我的答案,但是如果你没有在Window.m中调用[super mouseDown:theEvent](顺便说一下,它应该被称为WindowController.m),那么你就会打破响应者链。因此您的视图控制器无法看到它。我是对的吗?
