Question

My code won’t work and I don’t know why

the following works:

NSString *  words (void) {


    return [NSString stringWithFormat:@"You sent %d words\n", 1];

}

but this won’t work:

NSString *  words (void) {

    return  [[[NSString alloc] stringWithFormat:@"You have %d words\n", 1] autorelease];

}

What’s wrong, when I’m releasing it, then it wont work. Help me please.

Answer 1

Change stringWithFormat: to initWithFormat:.

stringWithFormat: is a class method so it is called when the NSString class itself is the receiver. initWithString: is an instance method so it is called when you have an NSString instance as the receiver, like what is returned from [NSString alloc].
