mono touch登录设计

需要对MonoTouch.Dialog-1进行引用；

using System;
using System.Collections.Generic;
using System.Linq;

using MonoTouch.Foundation;
using MonoTouch.UIKit;
using MonoTouch.Dialog;
using System.Diagnostics;

namespace MTDLoginDemo
{
    [Register ("AppDelegate")]
    public partial class AppDelegate : UIApplicationDelegate
    {
        // class-level declarations
        UIWindow window;
        EntryElement login, password;

        public override bool FinishedLaunching (UIApplication app, NSDictionary options)
        {
            window = new UIWindow (UIScreen.MainScreen.Bounds);

			window.RootViewController = new DialogViewController (new RootElement ("Login") {
				new Section ("用户登录"){
					(login = new EntryElement ("用户名", "输入用户名", "")),
					(password = new EntryElement ("密码", "用户密码", "", true))
                },
                new Section ("caption1231","footer123131221321") {
					new StringElement ("登录", delegate{
						Alert(login.Value+" " +password.Value);
					})
                }
            });

            window.MakeKeyAndVisible ();

            return true;
        }

		private void Alert(string msg)
		{
			UIAlertView av = new UIAlertView ("提示", msg, null, "确定", null);
			av.Show ();
		}
    }
}

效果图： 这里需要指出的是 Section有5个重载，可以自行试验一下，uiview相当于在上面或下面添加uiview对象的具体实例
