我想实现一个非常简单的任务 – 通过按下按钮来更改容器视图的ViewController：
在我的示例中,ViewController1使用Interface Builder嵌入到Container视图中.通过按下Button ViewController2,我想将视图更改为第二个ViewController.
我很困惑,因为如果我创建一个Outlet,Container View本身似乎是一个NSView,据我所知,NSView不能包含VC.真的很感谢你的帮助！
请注意,要使其工作,您必须将故事板标识符添加到视图控制器,这可以转到故事板,然后在右侧窗格中选择Identity Inspector,然后在Identity子类别中输入Storyboard ID.
然后,ViewController的这个实现将实现您正在寻找的.
import Cocoa
class ViewController: NSViewController {
// link to the NSView Container
@IBOutlet weak var container : NSView!
var vc1 : ViewController1!
var vc2 : ViewController2!
var vc1Active : Bool = false
override func viewDidLoad() {
super.viewDidLoad()
// Make sure to set your storyboard identiefiers on ViewController1 and ViewController2
vc1 = nsstoryboard(name: "name",bundle: nil).instantiateController(withIdentifier: "ViewController1") as! ViewController1
vc2 = nsstoryboard(name: "name",bundle: nil).instantiateController(withIdentifier: "ViewController2") as! ViewController2
self.addChildViewController(vc1)
self.addChildViewController(vc2)
vc1.view.frame = self.container.bounds
self.container.addSubview(vc1.view)
vc1Active = true
}
// You can link this action to both buttons
@IBAction func switchViews(sender: NSButton) {
for sView in self.container.subviews {
sView.removeFromSuperview()
}
if vc1Active == true {
vc1Active = false
vc2.view.frame = self.container.bounds
self.container.addSubview(vc2.view)
} else {
vc1Active = true
vc1.view.frame = self.container.bounds
self.container.addSubview(vc1.view)
}
}
}
