? ? 本節主要講述在蘋果環境中使用monodevelop開發ipad的一個實例，具體操作如下

? ? 1、新建項目 選擇monotouch--ipad--Empty project 命名為iPad01

? ? 2、添加新文件，選擇monotouch--ipad view，命名為showView，這樣會在項目中多出來三個文件。

? ? 3、在AppDelegate.cs中添加如下代碼，以在運行后，初始化運行界面為ShowView；

? ??

1 UIWindow window; 2 showViews shows; 3 4 public override bool FinishedLaunching(UIApplication app, NSDictionary options) { 5 // create a new window instance based on the screen size 6 window = new UIWindow(UIScreen.MainScreen.Bounds); 7 shows = new showViews(); 8 window.RootViewController = shows; 9 // If you have defined a view, add it here: 10 // window.AddSubview (navigationController.View); 11 12 // make the window visible 13 window.MakeKeyAndVisible(); 14 15 return true; 16 }

? ? ? ?4、添加新類MyViewController.cs，此類繼承UIViewController，重寫ipad的自動旋轉行為，代碼如下：

? ? ??

using MonoTouch.UIKit;namespace ipad01 {public class MyViewController:UIViewController {public MyViewController() {}public override bool ShouldAutorotateToInterfaceOrientation(UIInterfaceOrientation toInterfaceOrientation) {return true;}} }

?

? ? ? ?5、在showViews.cs中添加如下代碼

1 public override void ViewDidLoad() { 2 base.ViewDidLoad(); 3 4 var text = new UITextView(); 5 text.Text = "gwtGolden Gate Bridge,\nSan Francisco"; 6 text.Font = UIFont.FromName("Helvetica", 36f); 7 text.Frame = new System.Drawing.RectangleF(200, 40, 400, 100); 8 text.AutoresizingMask = UIViewAutoresizing.FlexibleLeftMargin | UIViewAutoresizing.FlexibleTopMargin | 9 UIViewAutoresizing.FlexibleRightMargin | UIViewAutoresizing.FlexibleBottomMargin; 10 text.ScrollEnabled = false; 11 text.Editable = false; 12 UIImage image = UIImage.FromFile("GoldenGate.jpg"); 13 UIImageView imageView = new UIImageView(image); 14 var customScrollView = new UIScrollView(this.View.Bounds); 15 customScrollView.AutoresizingMask = UIViewAutoresizing.FlexibleHeight 16 | UIViewAutoresizing.FlexibleWidth; 17 customScrollView.AddSubview(imageView); 18 19 20 customScrollView.PagingEnabled = false; // freeform scrolling 21 customScrollView.ContentSize = imageView.Frame.Size; 22 customScrollView.MaximumZoomScale = 4f; 23 customScrollView.MinimumZoomScale = 0.25f; 24 customScrollView.Bounces = false; 25 customScrollView.BouncesZoom = false; 26 customScrollView.IndicatorStyle = UIScrollViewIndicatorStyle.White; 27 customScrollView.ViewForZoomingInScrollView = delegate (UIScrollView sender) { 28 return imageView; 29 }; 30 customScrollView.ContentOffset = new System.Drawing.PointF(250, 20); 31 customScrollView.ZoomScale = 1.3f; // 32 var customViewController = new MyViewController(); 33 customViewController.Add(customScrollView); 34 customViewController.Add(text); 35 this.View.Add(customViewController.View);}

? ? ? ? 7，ok，將要使用的圖像文件添入到項目，并保證其右鍵Build Action屬性為Content。程序運行效果圖如下：
