A simple program

[hari]

I have created a simple program that has a Photo class with these two instance variables
caption, photographer.
The following is the code.

photo.h

@interface Photo : NSObject {
NSString * caption;
NSString * photographer;
}
@property (retain) NSString * caption;
@property (retain) NSString * photographer;

@end

photo.m

@implementation Photo

@synthesize caption;
@synthesize photographer;

- (void) dealloc {
   [caption release];
   [photographer release];
   [super dealloc];
}
@end

main.m

#import "Photo.h"

@implementation main

int main (int argc, char *argv[]) {

   Photo *obj = [[Photo alloc]init];
   obj.caption = "Evening";
   obj.photographer = "Hari";
   NSLog([obj caption]);
   NSLog([obj photographer]);
   [obj dealloc];
}
@end

When I build and run, I get the following output.

2011-02-22 11:56:03 test_1[1402:a0f] *** __NSAutoreleaseNoPool(): Object 0x100002078 of class NSCFString autoreleased with no pool in place - just leaking

Can someone please explain me why I am getting the two statements other than what I'm printing?

You are geting the warnings because you are missing an autorelease pool. Any object that is using autorelease will leak, and therfore the warning.
To solve/remove the just init an autorelease pool and drain it when your done.
Something like this:

int main(blabla){
NSAutoreleasePool * pool = [[NSAutoreleasePool alloc]init];
//your code
[pool drain]
}

Please correct me if im wrong though
