[MonoTouch] Subview not displaying

[Tomasz Cielecki]

I am thinking in the lines of the RectangleF classes are relative to
each other when they are subviewed. So when you set the image for your
Week tab, it gets set outside of the View and is not visible at all.
Try changing weekImageView = new RectangleF(120f, 10f, 60f, 40f); to
weekImageView = new RectangleF(20f, 10f, 60f, 40f);

Otherwise the two tabs are identical and I cannot see why it should not show up.
