【英文标题】：How to push from one NSViewcontroller to another NSViewcontroller in Mac OS X application?

【问题描述】：

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];

【参考方案1】：

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

【参考方案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

这是 ios 应用程序的代码工作，但我想要 Mac OS X 应用程序。
