c# - 在同一 View Controller 中添加 Collection View 和 TableView - Xamarin iOS

Question

我正在创建一个 iPAD 应用程序。我需要在同一个 View Controller 中有一个 UI Collection View 和一个 TableView 。 (屏幕分为 70% - Collection View 和 30% TableView

允许我执行此操作的最佳策略是什么。

PS:我的要求不允许我使用 Split View

公共(public)部分类 POSScreen : UIViewController { UIViewController 主 Controller ；

    UIViewController SecondaryController;

    UIView MainView;
    UIView SecondaryView;

    /* The Widths */
    nfloat leftSide;
    nfloat rightSide;

    public POSScreen () : base ("POSScreen", null)
    {



    }

    public override void DidReceiveMemoryWarning ()
    {
        // Releases the view if it doesn't have a superview.
        base.DidReceiveMemoryWarning ();

        // Release any cached data, images, etc that aren't in use.
    }

    public override void ViewDidLoad ()
    {
        base.ViewDidLoad ();

        try {
            // Perform any additional setup after loading the view, typically from a nib.
            leftSide = ((nfloat.Parse("65") / nfloat.Parse("100")) * nfloat.Parse( View.Frame.Width.ToString()));
            rightSide = ((nfloat.Parse("35") / nfloat.Parse("100")) * View.Frame.Width);

            MainController = new CategoriesProductsSimpleCollectionViewController();
            SecondaryController = new RightSideItemDetail ();

            (MainController as IViewController).SetCollectionViewFrame (new CoreGraphics.CGRect (0, 40, leftSide, View.Frame.Height));
            (SecondaryController as IViewController).SetCollectionViewFrame (new CoreGraphics.CGRect (View.Frame.Width, 40, rightSide, View.Frame.Height));


            this.Add (this.MainController.View);
            this.Add (this.SecondaryController.View);
        } catch (Exception ex) {
            Console.WriteLine (ex.Message);
        }



    }
}

谢谢

Answer 1

1)创建 Controller

public SomeViewController(UIColor color, CGRect frame) : base("SomeViewController", null)
{
     this.color = color;
     this.frame = frame;
}

public override void ViewDidLoad()
{
     base.ViewDidLoad();

     this.View.BackgroundColor = color;
     this.View.Frame = frame;
}

2) 在您想要子 Controller 的 Controller 中:

var MainController = new SomeViewController(UIColor.Black, new CGRect(0, 0, 100, 500));
var SecondaryController = new SomeViewController(UIColor.Green, new CGRect(150, 0, 100, 500));

this.AddChildViewController(MainController);
this.AddChildViewController(SecondaryController);
this.Add(this.MainController.View);
this.Add(this.SecondaryController.View);

我创建的 CGRect 只是示例。您可以使用计算正确的值UIScreen.MainScreen.Bounds;
