Thanks Craig, I will take a look at that. But I've tracked down my main
bug
Calling this method on a timer will always eventually crash. GC is not
working here, and I am
Completely out of ideas.....
Public class viewSwitcher : UIScrollView
.....
Initialise method...
var timer =
NSTimer.CreateRepeatingScheduledTimer(TimeSpan.FromSeconds(.5),
myTimer);
.....
private void myTimer() {
/* foreach (UIView subview in
Subviews) {
subview.RemoveFromSuperview();
subview.BackgroundColor.Dispose();
subview.Dispose();
} */
if (Subviews.Length > 0)
{
var sv =
Subviews[0];
sv.RemoveFromSuperview();
sv.BackgroundColor.Dispose();
sv.Dispose();
sv =
null; // cannot do this in a foreach loop
}
// GC.Collect();
trace("svc=" +
Subviews.Length); // always 0
using (UIView view =
new UIView(new RectangleF(0,0,768,1024))) {
var idx=
(globalcounter % 4) + 1;
globalcounter++;
view.BackgroundColor =
UIColor.FromPatternImage(UIImage.FromFile("assets/gallery/pic_" + idx +
".jpg"));
AddSubview(view);
}
trace("added");
}
This is my test code to find out why my App is crashing. What is wrong
with the code above? Without the BGImage, it doesn't crash.
It runs for about a minute before running out of memory.
Thanks,
Jon

CATiledLayer might help
Sorry I don't have anything more sophisticated, but there's a basic
example here

Hi,
Anyone know the best technique for a large paged, scrollable area. I
have tried a UIScrollView with a large contentsize, but I
Am getting memory issues and crashes.
Is there a viewcontroller that can manage preloading and side scrolling.
Thanks,
Jon
