NSMutableDictionary autorelease chrashes application



Hi!

I'm a rookie with Cocoa development, please excuse if this question is stupid, but I'm struck with memory management (an even Aaron's book doesn't help me):

In a method I use a (temporary) dictionary "vAttributes" to read an object from an instance variable "vColors" (a dictionary, too):

- (NSString *)descriptionByColorCode:(int)colorCode
{
NSMutableDictionary *vAttributes = [[NSMutableDictionary alloc] init];

vAttributes = [vColors objectForKey:[NSNumber numberWithInt:colorCode]];
return [vAttributes objectForKey:@"colorDescription"];
}


It is my understanding, that after the "alloc" message "vAttributes"' retain count is 1 and as I use it in the return statement, a "release" out of question. So "vAttributes" should receive an "autorelease" message before the return statement to avoid an object leak, but than the application crashes after the first invokation of this method.

... where am I wrong?
