  1.2 NSWindowController
  1.1 区别

1.1 NSViewController

KKF *kkf = [[KKF alloc]initWithNibName:@"KKF" bundle:nil];

__weak __typeof(kkf) wkkf = kkf;

kkf.blockHomeViewController = ^(){
    
    [wkkf.presentingViewController dismissViewController:wkkf];
    
};

[[NSApplication sharedApplication].keyWindow.contentViewController presentViewControllerAsSheet:kkf];

1.2 NSWindowController

（1）创建子类WindowController，继承与NSindowController。

（2）创建新的Window

self.windowController = [[WindowController alloc]initWithWindowNibName:@"WindowController"];

[self.windowController showWindow:self];

一定要定义成全局的

1.3 NSViewController 和 NSWindowController 区别

    NSViewController：内部套嵌

    NSWindowController：独立的新窗口
