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

UIButton *x=[UIButton buttonWithType:UIButtonTypeRoundedRect];

Here, I have not used “alloc” function.

The questions for this statements are as follow.

  • If we are using imageview for the same situation, we have to create an temp imageview add to your current view and release it. What to do for button?
  • How are buttons allocated and de-allocated?
  • If buttons are allocated? How it’s memory is been managed?
  • Now when I use [x release]; – is it right or wrong?

    No alloc/init or new so it will be autoreleased when it is no longer needed. When you add it to the UIView the count is increase and retained by the view, then also released when the view is released.
