UUID Category

Here's an NSString category for creating UUID strings that might come in handy. As always, you can do whatever you want with code that I put on this blog, but I take no responsibility for it or what you do with it. :-)

Header file (UUID.h):

#import <Foundation/Foundation.h>
 
@interface NSString (UUID)
 
+ (NSString *)stringWithUUID;
 
@end

Implementation file (UUID.m):

#import "UUID.h"
 
@implementation NSString (UUID)
 
+ (NSString *)stringWithUUID
{
    CFUUIDRef uuidObject = CFUUIDCreate(nil);
    NSString *uuidString = (NSString *)CFUUIDCreateString(nil, uuidObject);
    CFRelease(uuidObject);
    return [uuidString autorelease];
}
 
@end

Hello, my name is Martin Johannesson and this is my home on the web. I live in Stockholm, Sweden, where I work as a software engineer at a software company.

Ever since I was a kid and discovered the art of programming on my C64, I've been tinkering with my own little software projects and experiments. This site is one such experiment.
