[Solved] How to convert decimal into octal in objective c

by


You have to initialize a new NSString object using the right format specifier.

Like :

int i = 9;
NSString *octalString = [NSString stringWithFormat:@"%o", i]; // %O works too.

This will create an autoreleased NSString object containing octal string representation of i. In case you start from a NSString
containing a decimal number representation, you should first retrieve the number using :

int i = [myDecimalNumberAsAString intValue];

Here is a link to the format specifiers reference.

Hope this helps.
