Question

我在元素包（here）中使用MonotouchDialog中的SimpleMultilineEntryElement。

无论高度设置如何，此元素仍继续显示在“默认”表格单元格高度上。实际的可编辑部分各不相同，但背景单元格轮廓没有。很多浏览表明需要实施SizingSource，我已经做到了。因此，使用非常脆弱的解决方法，我现在可以选择性地调整细胞大小。在Root元素上使用UnevenRows属性没有帮助。试图获取该索引处的单元格会杀死该应用程序，即使索引肯定会被返回。

有没有办法让它使用我为Multiline入门元素定义的高度属性？

使用System; 使用System.Drawing; 使用MonoTouch.Dialog; 使用MonoTouch.Foundation; 使用MonoTouch.UIKit; 使用ElementPack; 使用System.Collections.Generic;

命名空间MyNameSpace { //编辑现有项目或如果不存在则添加一个

public partial class ProjectEdit：DialogViewController { 项目_p; UINavigationController _nc;

public ProjectEdit (Project p, UINavigationController nc) : base(null, true)
{
    _p = p;
    _nc = nc;

    if (_p == null)
    {
        _p = new Project();
        _p.InitialiseProjectDefaults();
    }

}

public override Source CreateSizingSource (bool unevenRows)
{
    //if (unevenRows)
    {
        return new unevenSizingSource(this);
    }
}

public class unevenSizingSource : DialogViewController.SizingSource
{
    public unevenSizingSource(DialogViewController vc) : base (vc)
    {

    }

    public override float GetHeightForRow (UITableView tableView, NSIndexPath indexPath)
    {
        // workaround to resize selectively

        // location
        if (indexPath.Section == 1 && indexPath.Row == 0)
        {
            return 200;
        }
        // description
        if (indexPath.Section == 2 && indexPath.Row == 0)
        {
            return 200;
        }

        return 200;
    }
}

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


}

public override void ViewWillAppear (bool animated)
{
    base.ViewWillAppear (animated);

    // Client selection
    ClientListViewController cl = new ClientListViewController(_nc, _p);

    var basicDetailsSection = new Section("Client") {
        new StringElement(_p.ClientDisplayName, delegate { _nc.PushViewController(cl, true); })
        //new UIViewElement ("", new GapElement (), true)
    };

    var locationSection = new Section("Location") {
        new SimpleMultilineEntryElement ("", "This is the\n location.") { Editable = true, Height = 200,  } 
    };

    var descSection = new Section ("Job Description"){
        new SimpleMultilineEntryElement ("", "This is the\n description") { Editable = true, Height = 200 } 
    };

    Root = new RootElement ("Project Details") {
        basicDetailsSection, locationSection, descSection
    };

}

}

您必须在视图出现之前设置Root.UnevenRows。控制器示例 -

using System;
using MonoTouch.Dialog;
using ElementPack;

namespace Test1
{
    public class Test2ViewController : DialogViewController
    {
        public Test2ViewController (): base(new RootElement("test"))
        {
            Root.UnevenRows = false;

            Root.Add (new Section () 
                      {
                        new SimpleMultilineEntryElement(string.Empty, "value")
                        {
                            Height = 150, Editable = true
                        },
                        new SimpleMultilineEntryElement(string.Empty, "value2")
                        {
                            Height = 250, Editable = true
                        }});
        }
    }
}
