How can i draw lines with "Draw In Rect" with format (center,right,left)?

Question

I want to make a UIimage with DrawInRect with alignment text, multiple strings but each string with the alignment that i want.

i made this code but the final image doesn't have the alignment, i been searching and testing, and modifing the code, but i can't find the solution, please help me.

Thank You.
