How to convert hexadecimal string to decimal?

Question

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. T

Answer 1

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).
