如何計算MVVMCross Xamarin.iOS中的應用程序空閒時間？

Question

我正在使用MVVMCross在Xamarin.iOS中開發iOS Universal Application。我想計算應用我發現下面的有益的幫助

iOS:Convert ObjC code to C#, How to know the time app has been idle

但是有當我嘗試用MVVMCross這是 AppDelegate.cs在MvvmCross從MvxApplicationDelegate.cs繼承使用此問題的空閒時間

我無法在AppDelegate中覆蓋下面的事件，因爲它不是壓倒一切的UIApplication

public override void SendEvent (UIEvent uievent) 
    { 
     base.SendEvent (uievent); 
     var allTouches = uievent.AllTouches; 
     if (allTouches.Count > 0) { 
      var phase = ((UITouch)allTouches.AnyObject).Phase; 
      if (phase == UITouchPhase.Began || phase == UITouchPhase.Ended) 
       ResetIdleTimer(); 
     } 
    } 

Answer 1

你是接近的答案。

在默認的MvvMCross項目中，有一個Main.cs，其中包含Application類。

你只需要更換空在下面與您的UIApplication的子類名行

UIApplication.Main(args, null, "AppDelegate"); 

例如，如果你的類名是從UIApplication的繼承MyApplication的話，應該是像

UIApplication.Main(args, "MyApplication", "AppDelegate"); 

並且添加類別MyApplication

[Register("MyApplication")] 
public class MyApplication : UIApplication 
{ 
    public override void SendEvent(UIEvent uievent) 
    { 
     base.SendEvent(uievent); 
     var allTouches = uievent.AllTouches; 
     if (allTouches.Count > 0) 
     { 
      var phase = ((UITouch)allTouches.AnyObject).Phase; 
      if (phase == UITouchPhase.Began || phase == UITouchPhase.Ended) 
       ResetIdleTimer(); 
     } 
    } 
}
