Answer 1

Note: These are the basic things that you can get through googling itself. Check this link.

Hints for your scenario:

-Create a view with 2 buttons, 1 label

-Set the IBOutlet label

-Set tag for each buttons

-Assign a same action[say -(IBAction) buttonAction: (id)sender] for both buttons,

-Have one global integer varible(say val)

-Code as follows

-(IBAction)buttonAction: (id)sender
{
 UIButton *but=(UIButton *)sender;
 if(but.tag==1)
 {
   val++;
   [label setText:[NSString stringWithFormat:"%@"],val];
 }
 else
 {
   val--;
   [label setText:[NSString stringWithFormat:"%@"],val];
 }
}
