Question

How can I implement the previous and forward swipe gestures in a webview... I ve read through the Handling Trackpad Events guide, but I still can t get it right...

I ve试图贬低网上意见、NSView、NSWindow,但没有工作。我甚至可以把它称作雕塑活动......。我在这里做了什么错误? 增编

-- webView.h --


#import <Cocoa/Cocoa.h>
#import <WebKit/WebKit.h>

@interface swipeView : WebView
@end



-- webView.m --

- (void) awakeFromNib{
    [self setAcceptsTouchEvents:YES];
    [self acceptsFirstResponder];
}


- (void) scrollWheel:(NSEvent *)theEvent{
    NSLog(@"scroll");
}

Answer 1

I guess, you have your answer already, but here is what would have been mine:

不使用这种方法

[self acceptsFirstResponder]

你们必须执行这一纲领,并将之交回你。

- (BOOL) acceptsFirstResponder
{
    return YES;
}

欢乐!
