如何在 Mac OS X 应用程序中从一个 NSViewcontroller 推送到另一个 NSViewcontroller？

Question

我尝试了下面的代码，但没有工作。我是 Mac OS X App 的新手，请帮助我。

NSStoryboard *Story=[NSStoryboard storyboardWithName:@"Main" bundle:nil];

TableViewVC *Controller=[Story instantiateViewControllerWithIdentifier:@"TableViewVC"];

[self presentViewController:Controller animator:YES];

这里有四种方式来呈现 NSViewController

• AsPopover

  - (IBAction)presentAsPopover:(NSButton *)sender {
      NSViewController* vc = [[MyViewController alloc] initWithNibName:nil bundle:nil];
      [self presentViewController:vc
          asPopoverRelativeToRect:sender.frame
                           ofView:self.view
                    preferredEdge:NSMinYEdge
                         behavior:NSPopoverBehaviorTransient];
  
  }
  

• 表格

  - (IBAction)presentAsSheet:(NSButton *)sender {
      NSViewController* vc = [[MyViewController alloc] initWithNibName:nil bundle:nil];
      [self presentViewControllerAsSheet:vc];
  
  }
  

• 作为模态

  - (IBAction)presentAsModal:(NSButton *)sender {
      NSViewController* vc = [[MyViewController alloc] initWithNibName:nil bundle:nil];
      [self presentViewControllerAsModalWindow:vc];
  
  }
  

• 与动画师

  - (IBAction)presentWithAnimator:(NSButton *)sender {
      id animator = [[MyCustomAnimator alloc] init];
      NSViewController* vc = [[MyViewController alloc] initWithNibName:nil bundle:nil];
      [self presentViewController:vc animator:animator];
  
  }
  

这里是动画师：

@interface MyCustomAnimator : NSObject <NSViewControllerPresentationAnimator>

@end

@implementation MyCustomAnimator

• 显示

  - (void)animatePresentationOfViewController:(NSViewController *)viewController fromViewController:(NSViewController *)fromViewController {
  
      NSViewController* bottomVC = fromViewController;
      NSViewController* topVC = viewController;
  
      // make sure the view has a CA layer for smooth animation
      topVC.view.wantsLayer = YES;
  
      // set redraw policy
      topVC.view.layerContentsRedrawPolicy = NSViewLayerContentsRedrawOnSetNeedsDisplay;
  
      // start out invisible
      topVC.view.alphaValue = 0;
  
      // add view of presented viewcontroller
      [bottomVC.view addSubview:topVC.view];
  
  
      // adjust size and colour
      CGRect frame = NSRectToCGRect(bottomVC.view.frame);
      frame = CGRectInset(frame, 40, 40);
      [topVC.view setFrame:NSRectFromCGRect(frame)];
      topVC.view.layer.backgroundColor = [NSColor grayColor].CGColor;
  
      // Do some CoreAnimation stuff to present view
      [NSAnimationContext runAnimationGroup:^(NSAnimationContext *context) {
          context.duration = 0.5;
          topVC.view.animator.alphaValue = 0.8;
      } completionHandler:nil];
  
  }
  

• 隐藏

  - (void)animateDismissalOfViewController:(NSViewController *)viewController fromViewController:(NSViewController *)fromViewController {
  
      //NSViewController* bottomVC = fromViewController;
      NSViewController* topVC = viewController;
  
      // make sure the view has a CA layer for smooth animation
      topVC.view.wantsLayer = YES;
  
      // set redraw policy
      topVC.view.layerContentsRedrawPolicy = NSViewLayerContentsRedrawOnSetNeedsDisplay;
  
      // Do some CoreAnimation stuff to present view
      [NSAnimationContext runAnimationGroup:^(NSAnimationContext *context) {
          context.duration = 0.5;
          topVC.view.animator.alphaValue = 0;
      } completionHandler:^{
          [topVC.view removeFromSuperview];
      }];
  
  }
  
  @end
  

记住

控制 NSViewController 的行为，

NSViewController 的xib 文件存在，很容易控制。

没有xib文件，或者在storyboard中设置，有点复杂

Answer 2

let storyboard = UIStoryboard(name: "Main", bundle: nil)
let myVC = storyboard.instantiateViewControllerWithIdentifier("TableViewVC")
self.presentViewController(myVC, animated: true, completion: nil)

您还应该像这样更改您的故事板 ID：

“TableViewVC”将此作为故事板ID
