C# ios使用仅图像代码实现PageController

我正在用xamarin开发一个ios应用程序，只有代码，没有故事板，也没有任何设计师。 我需要实现一个UiViewController，它包含许多图像，并水平滚动，就像

我没有找到适合我的东西。

有人给我一些建议或例子吗？

似乎你需要一个不带故事板或.xib的

UIPageViewController

您需要3个自定义类来实现它

MyPageViewController

-自定义

UIPageViewController

public class MyPageViewController : UIPageViewController
{
    private List<ContentViewController> pages = new List<ContentViewController>();

    public MyPageViewController() : base(UIPageViewControllerTransitionStyle.Scroll, UIPageViewControllerNavigationOrientation.Horizontal)
    {
        View.Frame = UIScreen.MainScreen.Bounds;

        pages.Add(new ContentViewController(0,UIColor.Red));
        pages.Add(new ContentViewController(1,UIColor.Green));
        pages.Add(new ContentViewController(2,UIColor.Blue));

        DataSource = new PageDataSource(pages);

        SetViewControllers(new UIViewController[] { pages [0] as UIViewController }, UIPageViewControllerNavigationDirection.Forward, false, null);
    }
}

ContentViewController

-自定义的

UIViewController

，只需添加属性

索引

public class ContentViewController : UIViewController
{
    private int index = -1;
    public int Index
    {
        get
        { 
            return index;
        }
    }

    public ContentViewController(int _index, UIColor backColor)
    {
        this.index = _index;
        this.View.Frame = UIScreen.MainScreen.Bounds;
        this.View.BackgroundColor = backColor;
    }
}

最后，覆盖

AppDelegate.cs

中的

FinishedLaunching

方法：

public override bool FinishedLaunching(UIApplication application, NSDictionary launchOptions)
{
    this.Window = new UIWindow(UIScreen.MainScreen.Bounds);
    this.Window.RootViewController = new MyPageViewController();
    this.Window.MakeKeyAndVisible();

    return true;
}

希望它能帮助你

如果您还有一些问题，请将其留在这里。

该链接适用于tvOS，而不是iOS

public override bool FinishedLaunching(UIApplication application, NSDictionary launchOptions)
{
    this.Window = new UIWindow(UIScreen.MainScreen.Bounds);
    this.Window.RootViewController = new MyPageViewController();
    this.Window.MakeKeyAndVisible();

    return true;
}
