I just had a question about the Frame Height.
frame.size.height = 450;
When I set a CGRect frame with height of 450 when the x= 0 and y = 0. The tableview extends almost all the way to the bottom. IS the number not based on pixels since I am testing it on an iPhone 5, the 1136. It shouldn't even have extended half way.
Thanks!
iOS screen coordinates are in UI points. One point is one pixel on the original-density screens, and one point is thus two pixels on the high resolution/retina displays.
Update from 2014: One point is even three pixels on the iPhone 6 Plus. (2018: and iPhone 6s Plus, 7 Plus, 8 Plus and X.)
