NSWindow纯代码设置

1. 创建一个window

NSRect frame = CGRectMake(0, 0, 200, 200); 
NSUInteger style = NSTitledWindowMask | NSClosableWindowMask |NSMiniaturizableWindowMask | NSResizableWindowMask; 
NSWindow *window = [NSWindow alloc]initWithContentRect:frame styleMask:style backing:NSBackingStoreBuffered defer:YES];
window.title = @"New Create Window"; 
//窗口显示 
[window makeKeyAndOrderFront:self]; 
//窗口居中 
[window center];

2. 关闭窗口退出程序

// 方法一：
- (BOOL)applicationShouldTerminateAfterLastWindowClosed:(NSApplication *)application {
    return YES;
}
// 方法二：利用 NSWindowDelegate 
- (void)windowWillClose:(NSNotification *)notification { 
    NSWindow *window = notification.object; 
    if(window == self.window) { 
        [NSApp terminate:self]; 
        // [[NSApplication sharedApplication] terminate:nil]; //或这句也行 
    } 
}

3. 设置window的image和title

- (void)setWindowIcon { 
    [self.window setRepresentedURL:[NSURL URLWithString:@"WindowTitle"]]; 
    [self.window setTitle:@"我是title"]; 
    NSImage *image = [NSImage imageNamed:@"windowIcon"]; 
    [[self.window standardWindowButton:NSWindowDocumentIconButton] setImage:image]; 
}

4. 最小化窗口

// 最小化窗口
[self.window miniaturize:sender];

5. 点击背景可以拖动窗口

[self.window setMovableByWindowBackground:YES];

6. 隐藏titlebar

// 设置标题隐藏
self.window.titleVisibility = NSWindowTitleHidden;
// 设置标题栏透明
self.window.titlebarAppearsTransparent = YES;
// 设置contentview与titlebar融合到一起（此时设置背景颜色也将影响titlebar的颜色）
self.window.styleMask = self.window.styleMask | NSWindowStyleMaskFullSizeContentView;
