How can I calculate font size for my UILabel?

Question

I have a UILabel measuring 984x728 px with variable text. How can I calculate the maximum font size to fit the UILabel?

use [lable setAdjustsFontSizeToFitWidth:YES]; – Vijay-Apple-Dev.blogspot.com Aug 30 '11 at 09:29 — Vijay-Apple-Dev.blogspot.com, Aug 30 '11 at 09:29

Create a font larger than you would ever want (48 points is probably good). Then use this:

CGFloat maxFontSize;
[string sizeWithFont:font minFontSize:0 actualFontSize:&maxFontSize forWidth:maxWidth lineBreakMode: UILineBreakModeClip];

maxFontSize will hold the largest size less than 48 and greater than 0 that will fit within maxWidth.

The API Rob mentions `sizeWithFont:` has been deprecated in iOS7. Please see this Stack Overflow question for a more complete response: http://stackoverflow.com/questions/18897896/replacement-for-deprecated-sizewithfont-in-ios-7 – Jeremy C. Feb 26 '14 at 22:37
