[[UIImageView new] init]和[[UIImageView alloc] init]之间的区别

Question

I am just wonder what is the difference between [[UIImageView new] init] and [[UIImageView alloc] init] .

is memory allocated in [[UIImageView new] init] as well ?

Answer 1

+ new is equivalent with + alloc followed by - init , so

UIImageView *iv = [[UIImageView alloc] init];

and

UIImageView *iv = [UIImageView new];

are right (and equivalent) and

UIImageView *iv = [[UIImageView new] init];

is wrong, since it calls - init twice.
