程式如何做日誌

   1:  var myString = "MyString";

   2:  var myFloat = 4.56f;

   3:  var myInt = 5;

   4:  Console.WriteLine(String.Format("log: {0}", myString)); 

   5:  Console.WriteLine(String.Format("log: {0}", myFloat)); 

   6:  Console.WriteLine(String.Format("log: {0}", myInt));

這些狀態說明會顯示在MonoDevelop的控制檯視窗和Xcode的管理器控制檯視窗中。

顯示影象
不使用UI生成器顯示影象在螢幕上的任何位置，您可以使用其他型別的檢視。

   1:  var imageRect = new RectangleF(0f, 0f, 320f, 109f); 

   2:  using (var myImage = new UIImageView(imageRect))

   3:  { 

   4:  myImage.Image = UIImage.FromFile("myImage.png");

   5:  myImage.Opaque = true;

   6:  view.AddSubview(myImage);

   7:  }

瀏覽器檢視
基本的UIWebView使用.

   1:  var webRect = new RectangleF(0f, 0f, 320f, 460f);

   2:  using (var webView = new UIWebView(webRect))

   3:  {

   4:  webView.BackgroundColor = UIColor.White;

   5:  var urlAddress = "http://www.google.com";

   6:   

   7:  var url = new NSUrl(urlAddress);

   8:  var urlRequest = new NSUrlRequest(url);

   9:  
 
webView.LoadRequest(urlRequest);

  10:  view.AddSubview(webView);

  11:  }

顯示網路指示器

   1:  var app = UIApplication.SharedApplication;

   2:  app.NetworkActivityIndicatorVisible = true; 

動畫:走馬燈圖片
顯示一系列連續的影象。影象在工程中藥設定為“內容”。

   1:  List<UIImage> myImages = new List<UIImage>();

   2:  myImages.Add(UIImage.FromFile("myImage1.png"));

   3:  myImages.Add(UIImage.FromFile("myImage2.png"));

   4:  myImages.Add(UIImage.FromFile("myImage3.png"));

   5:  myImages.Add(UIImage.FromFile("myImage4.png"));

   6:   

   7:  var myAnimatedView = new UIImageView(view.Bounds);

   8:  myAnimatedView.AnimationImages = myImages.ToArray();

   9:  myAnimatedView.AnimationDuration = 1.75; // Seconds

  10:  myAnimatedView.AnimationRepeatCount = 0; // 0 = Loops Forever

  11:  myAnimatedView.StartAnimating();

  12:  view.AddSubview(myAnimatedView);
