如何旋转 nscell
我正在制作 NSLevelIndicatorCell 的子类，我想垂直绘制它。这不起作用，我做错了什么？
- (void)drawWithFrame:(NSRect)cellFrame inView:(NSView *)controlView{
[[NSGraphicsContext currentContext] saveGraphicsState];
NSAffineTransform *transform = [NSAffineTransform transform];
[transform rotateByDegrees:90];
[transform concat];
[super drawWithFrame:cellFrame inView:controlView];
[[NSGraphicsContext currentContext] restoreGraphicsState];}
I am making a subclass of the NSLevelIndicatorCell and I want to draw it vertically. This doesn't work, what am I doing wrong?
- (void)drawWithFrame:(NSRect)cellFrame inView:(NSView *)controlView{
[[NSGraphicsContext currentContext] saveGraphicsState];
NSAffineTransform *transform = [NSAffineTransform transform];
[transform rotateByDegrees:90];
[transform concat];
[super drawWithFrame:cellFrame inView:controlView];
[[NSGraphicsContext currentContext] restoreGraphicsState];}
