this is a quite general question but i want to understand this please –

I usually build my apps without using IB.

  1. what are, the cons and pros of using IB vs. creating interface programmatically?
  2. what oppressions/code fits the init method and what is for the loadView method?
  3. is there any difference between loadView an ViewDidLoad or do i need to use only one of them?

thanks

    1. Pros are it’s quicker to get off the ground, you can adjust the positions of subviews usually quicker and definitely easier. Cons: You are limited to what you can do in Interface Builder, which is less than you can achieve in code almost always. Plus the interaction between how some views behave out of IB can catch new users.
    2. init and its namesakes should only be used for setting sane defaults of ivars. loadView is used for setting up the view hierarchy, starting with the backing view of your view controller. I.e., a special note; don’t reference the self.view property unless you are setting it, this will cause an infinite loop. Just a friendly protip.
    3. As mentioned before loadView is used to set up your backing view (it must be created by you if you override it), and viewDidLoad is called after the view has been loaded (after loadView is called). You do the appropriate items in the appropriate spots.
