关闭/最小化/全屏居中处理(仿Mac QQ)，效果如下

//  FSWindowCtl.m
@interface FSWindowCtl ()<NSWindowDelegate>

@end

@implementation FSWindowCtl

    [super windowDidLoad];

    [self.window setMovableByWindowBackground:YES];
    [self updateTitleBarOfWindow:false];
}

// 修改关闭、最小化、全屏的位置
- (void)updateTitleBarOfWindow:(BOOL)fullScreen {
    CGFloat kTitlebarH = 54.0;
    CGFloat kFullScreenButtonYOrigin = 3.0;
    NSRect windowFrame = self.window.frame;
    NSView *titlebarContainerView = [self.window standardWindowButton:NSWindowCloseButton].superview.superview;
    NSRect titlebarContainerFrame = titlebarContainerView.frame;
    titlebarContainerFrame.origin.y = windowFrame.size.height - kTitlebarH;
    titlebarContainerFrame.size.height = (CGFloat)kTitlebarH;
    titlebarContainerView.frame = titlebarContainerFrame;
    
    CGFloat buttonX = 12.0;
    NSButton *closeBtn = [self.window standardWindowButton:NSWindowCloseButton];

        buttonFrame.origin.x = (CGFloat)buttonX;
        buttonX = buttonFrame.size.width + buttonX + 6;
        [buttonView setFrameOrigin:buttonFrame.origin];
