Ex 16-4. My answer

[Nick Harvey]

I have written this in XCode which is slightly different to using command line.

NSString+TempFiles.h

#import <Foundation/Foundation.h>

@interface NSString (TempFiles)

+(NSString *) temporaryFileName;

@end

NSString+TempFiles.m

#import "NSString+TempFiles.h"

@implementation NSString (TempFiles)

+(NSString *) temporaryFileName
{
  NSProcessInfo *proc = [NSProcessInfo processInfo];
  return [proc globallyUniqueString];
}

@end

main.m
#import "NSString+TempFiles.h"

int main (int argc, const char * argv[])
{
  @autoreleasepool
  {
    for (int i = 1; i <= 10; i++) {
      NSLog(@"Temp file name %i = %@", i, [NSString temporaryFileName]);
    }
  }
    return 0;
}
