How to convert hexadecimal string to decimal?

The easiest way is to use an NSScanner specifically the methods scanHexInt: or scanHexLongLong: . Another possibility is to get the C string from the NSString and use C-style functions such as strtol (with base 16).

I would appreciate it if you could tell me how I can convert hexadecimal letters within an NSString, e.g. @"50A6C2", to decimals using Objective-C. Thanks in advance.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
