UIButton - should we release or not?

Question

I want to add a view button dynamically. Here is the code.

UIButton *x=[UIButton buttonWithType:UIButtonTypeRoundedRect];

I did not use the "alloc" function here.

The questions for these statements are as follows.

• If we use imageview for the same situation, we need to create a temp imageview to add to your current view and release it. What to do for the button?
• How are buttons allocated and unlocked?
• If the buttons are highlighted? How to manage memory?
• Now that I am using [x release]; - Right or wrong?

Answer 1

alloc/init new, , . UIView, , .

Answer 2

release . , .
alloc/init, .

Answer 3

UIButton *x=[UIButton buttonWithType:UIButtonTypeRoundedRect];

using this method u can not relese button

instead of using

UIButton *x = [[UIButton alloc]init];

and then release
