Resise NSWindow，不显示调整大小按钮
问题描述：
我想有一个可以调整大小但不显示左上角的小绿色调整大小按钮的NSWindow。这是可能吗？
I would like to have an NSWindow that is resizable but without showing the little green resize button in the top left corner. Is this possible?
答
创建NSWindow的自定义子类并重写standardWindowButton：forStyleMask：类方法
Create custom subclass of NSWindow and override "standardWindowButton: forStyleMask:" class method
@interface CustomWindow : NSWindow
@end
@implementation CustomWindow
+ (NSButton *)standardWindowButton:(NSWindowButton)b forStyleMask:(NSUInteger)styleMask
{
NSButton *button = [super standardWindowButton:b forStyleMask:styleMask];
if (b == NSWindowZoomButton) {
button.hidden = YES;
}
return button;
}
