c# iphone 开发 MonoDevelop viewController的使用

2016-08-11 11:18:48 admin 返回上一页

 

 

打开monoDevelop,选择Start a New Solution

\

 

选择iphone Window-based Project 项目名为firstViewController 确定

\

 

再按确定,系统自动建下面文件,

 

\

main.cs 内容

 

 

using System; 

using System.Collections.Generic; 

using System.Linq; 

using MonoTouch.Foundation; 

using MonoTouch.UIKit; 

 

namespace FirstViewController 

    public class Application 

    { 

        static void Main (string[] args) 

        { 

            UIApplication.Main (args); 

        } 

    } 

     

    // The name AppDelegate is referenced in the MainWindow.xib file. 

    public partial class AppDelegate : UIApplicationDelegate 

    { 

        // This method is invoked when the application has loaded its UI and its ready to run 

        public override bool FinishedLaunching (UIApplication app, NSDictionary options) 

        { 

            // If you have defined a view, add it here: 

            // window.AddSubview (navigationController.View); 

            window.MakeKeyAndVisible (); 

      

            return true; 

        } 

     

        // This method is required in iPhoneOS 3.0 

        public override void OnActivated (UIApplication application) 

        { 

        } 

    } 

 

这里重写的FinishedLaunching 方法,如果FinishedLaunching 方法不在10S内返回,那么iso就会关闭该应用程序!在这里不给添加太多的代码!

 

 

 

 

添加iPhone View with Controller ,在file->new->file  选择iPhone and iPad ->iPhone View with Controller

 

\

输入first,,按确定

 

 

展开Solution 里的first.xib

\

双击first.xib.cs

 

 

添加下面代码

 

 

 

view plain

private void butonClickFunction(object sender,EventArgs e ) 

        { 

 

            ((UIButton) sender).SetTitle("clicked!",UIControlState.Normal); 

        } 

public override void  ViewDidLoad() 

        { 

            button2=UIButton.FromType(UIButtonType.RoundedRect); 

            button2.Frame=new System.Drawing.RectangleF(100f,20f,60f,40f); 

            button2.SetTitle("click",UIControlState.Normal); 

            button2.TouchUpInside+=new System.EventHandler(butonClickFunction); 

            this.View.AddSubview(button2); 

            base.ViewDidLoad(); 

        } 

 

 

 

 

 

butonClickFunction 方法是button 点击操作时调用的方法

ViewDidLoad()  方法是重写ViewDidLoad 方法,这个方法是view 加载的时候触发的,在这个方法里可以加载一些控件和初始化操作,在这里我们添加一个UIbuttion ,这里的button2,在类开始添加申明,UIButtion button2 ,

UIButton.FromType(UIButtonType.RoundedRect);

这里的UIButtonType.RoundedRect  近回的是一个圆边的button ,也就是标准iso button

button.Frame=new System.Drawing.RectangleF(左上角的X,左上角的Y,宽度,高度)

button2.SetTitle("click",UIControlState.Normal); 设置标题,

button2.TouchUpInside+=new System.EventHandler(butonClickFunction);设置事件

this.View.AddSubview(button2);  把button2 添加到当前view 里,做为子view

base.ViewDidLoad();  调用父类的viewDidLoad 在xcode 里,在子类里调用父类方法,经常出现在,实列化类时候都是调用base.init 他们都 是NSObject 的子类

   

   

 

 

 

返回到main.cs

 

在FinishedLaunching 添加代码

 

public override bool FinishedLaunching (UIApplication app, NSDictionary options) 

        { 

            // If you have defined a view, add it here: 

            // window.AddSubview (navigationController.View); 

            first f=new first (); 

            window.AddSubview(f.View); 

            window.MakeKeyAndVisible (); 

     

            return true; 

        }

 

 

 

 

 

Build  and run
