iPhone UIView - Resize Frame to Fit Subviews

Question

Shouldn\'t there be a way to resize the frame of a UIView after you\'ve added subviews so that the frame is the size needed to enclose all the subviews? If your subviews are

When you make your own UIView class, consider overriding IntrinsicContentSize in the subclass. This property is called by OS to know the recommended size of your view. I will put code snippet for C# (Xamarin), but the idea is the same:

[Register("MyView")]
public class MyView : UIView
{
    public MyView()
    {
        Initialize();
    }

    public MyView(RectangleF bounds) : base(bounds)
    {
        Initialize();
    }

    Initialize()
    {
        // add your subviews here.
    }

    public override CGSize IntrinsicContentSize
    {
        get
        {
            return new CGSize(/*The width as per your design*/,/*The height as per your design*/);
        }
    }
}

This returned size depends completely on your design. For example, if you just added a label, then width and height is just the width and height of that label. If you have more complex view, you need to return the size that fits all your subviews.
