I solved my issue actually I didn't gave float values because of this I got exception.I gave CGFloat and gave values as integer like 400,350,etc but I need give 400.0f .so,I got this issue .Now it was cleared

Answer 2

You are calling UILabel frame methods, and probably calculating the value somehow and the result is a NaN, which means "not a number" and, as you correctly suggested, it can be the result of o divide-by-zero operation.

But it can appear for a lot other reasons: http://en.wikipedia.org/wiki/NaN
