Answer 1

Consider looking into the NSTimer class documentation.

Answer 2

You can use NSTimer object like this.

Create flag in your class BOOL restrictTap;

Add this methods:

// is your tap method
- (void) tap {
    if ( restrictTap ) {
        return;
    }

    // do your staff

    restrictTap = YES;
    [NSTimer scheduledTimerWithTimeInterval:3 
                                     target:self 
                                   selector:@selector(enableTap)
                                   userInfo:nil 
                                    repeats:NO];
}

- (void) enableTap {
    restrictTap = NO;
}

Answer 3

my code is something like this

if(bulletNo==-1) { bulletNo=6;

}

switch (bulletNo)

{
    case 6:
        [self.audioPlayer play ];
        bulletOne.hidden=FALSE;
        bulletTwo.hidden=FALSE;
        bulletThree.hidden=FALSE;
        bulletFour.hidden=FALSE;
        bulletFive.hidden=FALSE;
        bulletSix.hidden=FALSE; 
        break;


    case 5:
        [self.audioPlayer play ];
        bulletOne.hidden=FALSE;
        bulletTwo.hidden=FALSE;
        bulletThree.hidden=FALSE;
        bulletFour.hidden=FALSE;
        bulletFive.hidden=FALSE;
        bulletSix.hidden=TRUE;  
        break;

    case 4:
        [self.audioPlayer play ];
        bulletOne.hidden=FALSE;
        bulletTwo.hidden=FALSE;
        bulletThree.hidden=FALSE;
        bulletFour.hidden=FALSE;
        bulletFive.hidden=TRUE;
        bulletSix.hidden=TRUE;  

        break;

    case 3:
        [self.audioPlayer play ];
        bulletOne.hidden=FALSE;
        bulletTwo.hidden=FALSE;
        bulletThree.hidden=FALSE;
        bulletFour.hidden=TRUE;
        bulletFive.hidden=TRUE;
        bulletSix.hidden=TRUE;  

        break;

    case 2:
        [self.audioPlayer play ];

        bulletOne.hidden=FALSE;
        bulletTwo.hidden=FALSE;
        bulletThree.hidden=TRUE;
        bulletFour.hidden=TRUE;
        bulletFive.hidden=TRUE;
        bulletSix.hidden=TRUE;  

        break;

    case 1:
        [self.audioPlayer play ];
        bulletOne.hidden=FALSE;
        bulletTwo.hidden=TRUE;
        bulletThree.hidden=TRUE;
        bulletFour.hidden=TRUE;
        bulletFive.hidden=TRUE;
        bulletSix.hidden=TRUE;  



        break;

    case 0:
        [self.audioPlayer play ];
        bulletOne.hidden=TRUE;
        bulletTwo.hidden=TRUE;
        bulletThree.hidden=TRUE;
        bulletFour.hidden=TRUE;
        bulletFive.hidden=TRUE;
        bulletSix.hidden=TRUE;  

        reloadLabel.hidden=FALSE;

        [reloadbutton setHidden:NO];

        break;

    default:
        break;
}

on every tap,bullet value get decrement by one. i provided 6 bullet images,on each tap, bullet image gets visible and invidble,

now for ex if bullets ==60;

now,when the value of bulleNo becomes 0 ,on each 6th tap,all bullets gets invisible, so what i want is, wen all images gets invisble,i want to restrict user to tap. i already hv a shake function through which,when user shakes, all 6 images gets vissible.and wen all bullet images get visible,user start taps again...

hope m clear wat i want... quick reply is always appreciated... thanks anyways for replying dude.
