原生OSX狮子调整光标定制NSWindow或一个NSView(Native OSX Lion res

如果我们使用NSTrackingArea对于一些特定区域，然后我们就可以实现这样的方法来改变默认光标：

-(void)cursorUpdate:(NSEvent *)theEvent {
    [[NSCursor resizeLeftCursor] set];
}

我实现自定义调整为NSWindow ，它使用NSBorderlessWindowMask 。并希望使用本地狮子的两个箭头光标。但是，这种类型的游标不存在中NSCursor API 。

我能得到某种方式从代码，本地游标？
或者，也许我必须用手（不是一个好主意）重绘他们？

Answer 1:

WebKit的包含长得一模一样的系统所使用的游标，在以下目录中的图片：

/System/Library/Frameworks/WebKit.framework/Versions/Current/Frameworks/WebCore.framework/Resources/

...例如，文件“northWestSouthEastResizeCursor.png”。

Answer 2:

目前WebKit中的那些不可视网膜分辨率不幸的是，在看

/System/Library/Frameworks/ApplicationServices.framework/Versions/A/Frameworks/HIServices.framework/Versions/A/Resources/cursors

你会发现调整光标的PDF版本。

Answer 3:

下面是一些示例代码加载向量为基础的（并因此能够视网膜）从HIServices.framework光标：

NSString *cursorName = @"resizenortheastsouthwest";
NSString *cursorPath = [@"/System/Library/Frameworks/ApplicationServices.framework/Versions/A/Frameworks/HIServices.framework/Versions/A/Resources/cursors" stringByAppendingPathComponent:cursorName];
NSImage *image = [[NSImage alloc] initByReferencingFile:[cursorPath stringByAppendingPathComponent:@"cursor.pdf"]];
NSDictionary *info = [NSDictionary dictionaryWithContentsOfFile:[cursorPath stringByAppendingPathComponent:@"info.plist"]];
NSCursor *cursor = [[NSCursor alloc] initWithImage:image hotSpot:NSMakePoint([[info valueForKey:@"hotx"] doubleValue], [[info valueForKey:@"hoty"] doubleValue])];

请注意，我不知道这是否工作在沙盒应用程序。

Answer 4:

有建立这样光标无证方法。下面是一个例子：

#pragma clang diagnostic push
#pragma clang diagnostic ignored "-Wundeclared-selector"
    if ([NSCursor respondsToSelector:@selector(_windowResizeNorthSouthCursor)])
    {
        self.resizeUpDownCursor = [NSCursor performSelector:@selector(_windowResizeNorthSouthCursor)];
    }
    else
    {
        self.resizeUpDownCursor = [NSCursor resizeUpDownCursor];
    }
#pragma clang diagnostic pop

下面是在MacOS上塞拉利昂无证游标的完整列表：

[NSCursor _windowResizeWestCursor]
[NSCursor _windowResizeEastWestCursor]
[NSCursor _windowResizeNorthCursor]
