Answer 1

You should create button and add them as subView. When you need to put button at random location, you can use:

[button1 setFrame:CGRectMake(5,219,230,45)];
[button2 setFrame:CGRectMake(5,273,230,45)];
[button3 setFrame:CGRectMake(244,224,230,45)];
[button4 setFrame:CGRectMake(244,273,230,45 )];
