hi, im building iPhone app that downloads images (UIImageView) from internet and adding them to UIScrollView. This scroll view could contain 20 or more UIImageViews. Iam adding UIImages to UIImageView like this:
UIImageView *newView = [[UIImageView alloc] initWithImage: image];
Then I just scroll these images like in photo app. Problem is, when I put just 3 UIImageViews in UIScrollView everything works fine, but when I put more images, more memory is used, so that app can crash after 15 or more images. I can understand it that more images alloc more memory, but in Instruments i get allocated max 2-3 MB, but in device memory raises until it crashes. When I use simulator for OS 3.0 i can see memory rising like on device. On higher versions I dont see this memory raise, why is that?
