Hi,
Unfortunately, it still crashes at the same point around 102 iterations with
jetsam: kernel memory event (90), free: 604, active: 3645, inactive: 2080,
purgeable: 139, wired: 12350
Mon Jul 4 09:44:34 unknown SpringBoard[801] <Warning>: Received memory
warning. Level=2
This is the timer code.... I'm beginning to think that this is a monotouch
problem!
???

private void myTimer ()
{
InvokeOnMainThread (delegate {
if
(this.Subviews != null) {
for (int x=0; x<this.Subviews.Length; x++) {
var sv = this.Subviews[x];
sv.RemoveFromSuperview ();
sv.BackgroundColor.Dispose ();
sv.Dispose ();
trace("disposed");
sv = null;
}
}
GC.Collect();
trace ("svc=" +
Subviews.Length); // always 0
var idx =
(globalcounter % 4) + 1;
globalcounter++;
using (UIView
view = new UIView (new RectangleF (0, 0, Frame.Width, Frame.Height))) {
using (UIImage image = UIImage.FromFile("assets/i" + idx + ".jpg")) {
using (UIColor color = UIColor.FromPatternImage(image)) {
view.BackgroundColor = color;
AddSubview (view);
}
}
}
});
trace ("added " +
globalcounter);
}

(That goes for the add code as well -- anything that involves manipulating
UIViews. I don't know for sure that this is your problem but it's a good rule
of thumb in GUI systems regardless.)

Try invoking the actual removal code on the main thread (with
NSObject.InvokeOnMainThread or NSObject.BeginInvokeOnMainThread) and see if
that helps.

Try this:
using (var image = UIImage.FromFile(
"assets/gallery/pic_" + idx + ".jpg"))
using (var color = UIColor.FromPatternImage(image) {
view.BackgroundColor = color;
}
