Haven't run the code, but I'd think that what you want is:

NSMutableArray *array = [[NSMutableArray alloc] init];

I have read the memory management documentation over and over but still cannot work out the problem with this code, can anyone see it? I have spent hours on this!

+(NSMutableArray*)getStrings {
   NSMutableDictionary* dict = [[NSMutableDictionary alloc] init];
   [dict setValue: @"" forKey: [NSString stringWithString:@"one"]];
   [dict setValue: @"" forKey: [NSString stringWithString:@"two"]];

   NSMutableArray *array = [[NSMutableArray array] init];
   NSEnumerator* keyEnum = [dict keyEnumerator];
   NSString* key;
   while ((key = [keyEnum nextObject])) {
       [array addObject: key];
   }
   [dict release];

   return [array autorelease];
}

// Here is where I call the above function
NSMutableArray* a =[StringHelper getStrings];
[a retain];
for(int i=0;i<a.count;i++) {
   NSLog(@"> %@",(NSString*)[a objectAtIndex: i]);
}
[a release];

AFTER the code is complete I see the following message, the address location is always the pointer to the array created in the getStrings method.

2009-01-02 12:07:29.277 Test[5184:813] *** -[CFArray release]: message sent to deallocated instance 0x132950

Any help muchly appreciated. I have tried with and without the [a retain] and [a release].
