Answer 1

NSString *hexString = [NSString stringWithFormat:@"#%d", hexValue];

You are formatting it as a digit with %d

You want to format it as hex with %x or %X -- maybe as string %s I didnt check what the function is doing and what int hexValue is holding

d or i Signed decimal integer 392

x Unsigned hexadecimal integer 7fa

X Unsigned hexadecimal integer (capital letters) 7FA
