how to random placement of UIButton and value

Question

i have a question view and will show 4 answers, only 1 are correct.

but i do not want the same button to be always the correct answer.

i will like to know how do

Answer 1

create your own class with these 4 buttons. In this class you can store the positions of your buttons. then you can add a member function (something like the following) which will draw them:

-(void)drawButtonsWithIncorrectAtIndex:(int)index

Answer 2

I would suggest do not change the position of buttons rather what you can do is change the currentTitle property of the buttons randomly and once the user clicks the button ; you can get the currentTitle of the button and check if it is the correct answer or not.
