c# – 如何在Xamarin iOS中创建垂直滚动视图

我是ios开发的新手.我正在尝试在Xamarin iOS应用程序中创建一个垂直ScrollView.

下面是我的水平ScrollView代码

using System;

using UIKit;
using Foundation;
using CoreGraphics;
using System.Collections.Generic;

namespace TestApp
{
    public partial class ViewController : UIViewController
    {

    public ViewController (IntPtr handle) : base (handle)
    {
        ScrollingButtonsController ();
    }

    UIScrollView scrollView;
    List<UIButton> buttons;

    public override void ViewDidLoad ()
    {
        base.ViewDidLoad ();
        // Perform any additional setup after loading the view, typically from a nib.
        //MyScrollView.scrollEnabled=YES;
        //MyScrollView.contentSize= CGSizeMake(CGFloat.width, CGFloat.height);          

        //end
        nfloat h = 50.0f;
        nfloat w = 50.0f;
        nfloat padding = 10.0f;
        nint n = 100;

        scrollView = new UIScrollView {
            Frame = new CGRect (0, 100, View.Frame.Height, h + 2 * padding),
            ContentSize = new CGSize ((w + padding) * n, h),
            BackgroundColor = UIColor.Red,
            AutoresizingMask = UIViewAutoresizing.FlexibleWidth
        };

        for (int i=0; i<n; i++) {
            var button = UIButton.FromType (UIButtonType.RoundedRect);
            button.SetTitle (i.ToString (), UIControlState.Normal);
            button.Frame = new CGRect (padding * (i + 1) + (i * w), padding, w, h);
            scrollView.AddSubview (button);
            buttons.Add (button);
        }

        View.AddSubview (scrollView);

        //UIScrollView scrollView;
    //scrollView = new UIScrollView (
    //      new CGRect (0, 0, View.Frame.Width, View.Frame.Height));
    //  View.AddSubview (scrollView);



    }
    public void ScrollingButtonsController ()
    {
        buttons = new List<UIButton> ();

    }

    public override void DidReceiveMemoryWarning ()
    {
        base.DidReceiveMemoryWarning ();
        // Release any cached data, images, etc that aren't in use.
    }


}
}

我想创建一个垂直scrollview并添加一些可滚动的文本视图.有关如何做到这一点的任何想法？

如果您能详细说明如何在我的Main.storyboard文件中使用结构方案获取元素,我将不胜感激：

-Scroll View
--label
---Image View
---Text View
--label
---Image View
---Text View
--label
---Image View
---Text View
--label
---Image View
---Text View
--label
---Image View
---Text View

和更多…

解决方法:

您需要设置ScrollView Content Size Height,大于它的帧高.所以它会向上/向下滚动.滚动视图的宽度应与其内容宽度相同,因此不会向右/向左滚动.
