UIScrollView phantom subviews

NSArray *nibViews = [[NSBundle mainBundle] loadNibNamed:@\"AnalysisView\" owner:self options:nil];

Answer 1

UIScrollView by default contains 2 UIImageViews as subviews for scroll indicators. Although I can't find anything specific about scroll indicators implementation in docs, those imageviews are present in class declaration (see UIScrollView.h header):

UIKIT_CLASS_AVAILABLE(2_0) @interface UIScrollView : UIView <NSCoding> {
    ...
    UIImageView* _verticalScrollIndicator;
    UIImageView* _horizontalScrollIndicator;

You can also start assigning tags not from 0, but from some positive number - that way avoiding collision with standard subviews
