添加的UIViewController的.xib到UIViewController的按钮按在我的游戏

Question

我有一个显示各个项目的的CollectionView我需要让这个当指数在按下的项目的视图控制器...

func collectionView(_ collectionView: UICollectionView, didSelectItemAt indexPath: IndexPath) { 
    // handle tap events 
    if indexPath.item == 0 { 
     //add a viewcontroller for viewing content 
     //other things here for customizing that view data 
    } 
} 

...一个viewcontroller在屏幕上弹出不占用整个屏幕，但在主ViewController中间的一小部分

（我需要该视图是可重复使用和适应性）我已经尝试使viewController并将其添加到主ViewController作为排序的子视图，但没有运气

我想显示不同的信息取决于选择什么样细胞，如果你能帮助我，我将不胜感激

据我了解，你要打开它从厦门国际银行加载您ViewControllers自定义视图中查看或不同ViewController上的ViewControllers视图（显示collectionView中的各种项目）。

如果是，那么使用下面的代码

//Create optional property 

var myViewController : YourCustomViewController? 


func collectionView(_ collectionView: UICollectionView, didSelectItemAt indexPath: IndexPath) { 
// handle tap events 
     if indexPath.item == 0 { 
    //add below line to load custom View Xib 
    loadCustomView(onView:self.view)          
    //OR To Add ViewController View use below code 
    loadViewController(onView:self.view) 
    } 
} 

fun loadCustomView(onView:UIView) { 
    let allViewsInXibArray = Bundle.init(for: type(of: self)).loadNibNamed("CustomView", owner: self, options: nil) 
    //If you only have one view in the xib and you set it's class to MyView class 
    let myCustomView = allViewsInXibArray?.first as! CustomView 
    onView addSubview(myCustomView) 
    addConstraints(onView: myCustomView) 

} 

func loadViewController(onView:UIView) { 
    myViewController = YourCustomViewController(nibName: "TestViewController", bundle: nil); 
    onView addSubview((myViewController?.view)!) 
    addConstraints(onView: (myViewController?.view)!) 

} 

func addConstraints(onView : UIView) { 
    onView.translatesAutoresizingMaskIntoConstraints = false; 

    let widthConstraint = NSLayoutConstraint(item: onView, attribute: NSLayoutAttribute.width, relatedBy: NSLayoutRelation.equal, 
              toItem: onView.superview, attribute: .width, multiplier: 0.8, constant: 0) 
    let heightConstraint = NSLayoutConstraint(item: onView, attribute: .height, relatedBy: .equal, 
               toItem: onView.superview, attribute: .height, multiplier: 0.6, constant: 0) 
    let xConstraint = NSLayoutConstraint(item: onView, attribute: .centerX, relatedBy: .equal, toItem:onView.superview , attribute: .centerX, multiplier: 1, constant: 0) 
    let yConstraint = NSLayoutConstraint(item: onView, attribute: .centerY, relatedBy: .equal, toItem: onView.superview, attribute: .centerY, multiplier: 1, constant: 0) 
    NSLayoutConstraint.activate([widthConstraint, heightConstraint, xConstraint, yConstraint]) 

} 

而且你可以添加弹出和弹下的动画自定义视图。

评论我，如果你需要别的东西。
