Question

+I want to load a certain image by name.
This name is composed of the size and some strings.

The final results should for example be

“button_bg_124_84_down.png”
(without quotes)

I have

CGFloat nWidth = 124;
CGFloat nHeight = 84;

How would can I form such a string without any much mocking around, please?

I was hoping that I could simply say

NSString * mystring = "button_bg_" + nWidth + "_" + nHeight + "_down.png";

but that is seemingly not the way to do it.

Thank you.

Answer 1

NSString * mystring =[NSString stringWithFormat:@"button_bg_%.0f_%.0f_down.png", nWidth, nHeight];

EDIT: as you want 222 not 222.000000 so .0f is required to convert it into int value. otherwise decimal will get appended
