Question

I have seen 2 ways to create button.

UIButton *button = [[UIButton alloc]initWithFrame:CGRectMake(10, 220, 150, 30)];

and

UIButton *button = [UIButton buttonWithType:UIButtonTypeRoundedRect];

The first case is the normal way to create a button object. I have allocated and initialised a button instance and I have to release that. I am really confused about the second way. I have some questions regarding this.

1. Is a button instance created in this case?
2. What is the retain count of this button?
3. Should I release this button?

Answer 1

Hope this helps:

1. Yes button instance is created.
2. Retain count will be how do you add/retain.
3. You don’t need to release button if you have not created it by alloc.
