Question

I have a button on the view of iPhone built on mono touch.
When it is clicked, it fires an animation and then returns to the main animation.
Both animations are fired on an UIImageView which is on the same view where the button exists.

But it disappears when I click after two times?
I want the button always on the surface.

partial void TurnLightOnOrOff (MonoTouch.Foundation.NSObject sender)
        {
            TAMAM.coreLife.SwitchLightsStatus ();
            dayPartType = DayPart.CurrentDayPart ();
            if (dayPartType != DayPart.DayPartType.Night) {
                playMainAnim ();
                return;
            }
            var sound = SystemSound.FromFile (@"sound/Click.caf");
            sound.PlaySystemSound ();

            if (!TAMAM.coreLife.LightsOn) {

                myImages = new List<UIImage> ();
                myImages.Add (UIImage.FromFile (@"image/babysleep/babysleeplightoff10000.png"));
                myImages.Add (UIImage.FromFile (@"image/babysleep/babysleeplightoff20000.png"));
                myImages.Add (UIImage.FromFile (@"image/babysleep/babysleeplightoff30000.png"));
            var myAnimatedView = new UIImageView (this.animFrameRectangle);
                myAnimatedView.AnimationImages = myImages.ToArray ();
                myAnimatedView.AnimationDuration = 1; // Seconds
                myAnimatedView.AnimationRepeatCount = 0; // 0 = Loops Forever
                myAnimatedView.StartAnimating ();
                if (this.svBabyAge.Subviews.Length > 0) {
                    this.svBabyAge.Subviews [0].RemoveFromSuperview ();
                }
                if(this.ivBabyAge.Subviews.Length > 0)
                {
                    this.ivBabyAge.Subviews [0].RemoveFromSuperview ();
                }
                this.ivBabyAge.AddSubview (myAnimatedView);
                this.svBabyAge.AddSubview (this.ivBabyAge); 

            } else {
                playMainAnim ();
            }

        }

Answer 1

That was my fault that I confess now:
It was because I remove subviews’ element . My purpose was controlling the unnecessary elements to be removed but the buttons was removed in that loop.

Thanks for your time.
