macOS Using the garbage collector

[lee1210]

Ok I think I got it, but if I init a string with something I have to use alloc like this?

 NSString * string = [[NSString alloc] initWithFormat:@"'%@' has %d characters.",textViewString,[textViewString length] ];

So I can't do like this?

NSString * string = [NSString initWithFormat:@"'%@' has %d characters.",textViewString,[textViewString length] ];

Thanks for answering my questions! When I clear things I advance in my book again.

initWithFormat: is a - method, so you call it on an instance. There is a corresponding stringWithFormat: method that is a + method, called on the class. You'd pass this to NSString like your second example, and you'd get a pointer to an autoreleased Object back.

And you're welcome.

Oh I see now how the - and + differs.
