iOS - Get the "real" height of a letter

Question

I am trying to layout text on a UIView.

(The yellow area is the frame of the UILabel with a background color).

When I use sizeWithFont I get this, which has a very large space above the letter:

When I use font.pointSize i get this for "i" which is good-

BUT When i use it for "p" I get the precise height but the letter is drawn in the bottom and cropped.

**How can i get get the glyph only centered in the frame ? **

Thanks

There are a lot of properties on UIFont to help in this situation:

• pointSize
• ascender
• descender
• capHeight
• xHeight
• lineHeight
