Alloc and Init

[ace1009]

The book specifies that

and

are the same. I understand one is meant for convenience but is one way better practice than the other?

I am also curious whether nesting a message or not is better practice. It just says that nesting is more difficult to read and decipher.

Awesome books and thanks in advance for the help!

NSDate *now = [NSDate date];
and

NSDate *now = [[NSDate alloc] init];
are the same. I understand one is meant for convenience but is one way better practice than the other?

Both should do the same thing.

You should also be able to do:

NSDate *now = [NSDate new];
However, since the first one is more explicit, one can argue that it is a better choice.

Nesting makes the code more difficult to debug by hand or by using the debugger.

However, nesting alloc and init… methods has become the norm.

I think it’s by pure coincidence that the init method also does what the date method does? (return the current date)
