Repeating self performSelector

Question

I was just wandering If there is a simplier method to repeat the codes below for 20 seconds. If there is, how?

[self performSelector:@selector( move1) withObject:nil afterDelay:0.0];
[self performSelector:@selector( move2) withObject:nil afterDelay:0.2];
[self performSelector:@selector( move3) withObject:nil afterDelay:0.4];
[self performSelector:@selector( move1) withObject:nil afterDelay:0.8];
[self performSelector:@selector( move2) withObject:nil afterDelay:0.10];
[self performSelector:@selector( move3) withObject:nil afterDelay:0.12];

According to my opinion Just try this code below,

Take one NSInteger in your Controller's .h file, like this,

NSInteger intTmp;

then in .m file Call NSTimer method like this,

[NSTimer scheduledTimerWithTimeInterval:1.0 target:self selector:@selector(testMethod:) userInfo:nil repeats:YES];

And write selector like this

-(void)testMethod:(NSTimer *)pTmpTimer
{
    intTmp += 1;

    if(intTmp <= 20)
    {
        [self performSelector:@selector( move1) withObject:nil afterDelay:0.0];
        [self performSelector:@selector( move2) withObject:nil afterDelay:0.2];
        [self performSelector:@selector( move3) withObject:nil afterDelay:0.4];
        [self performSelector:@selector( move1) withObject:nil afterDelay:0.8];
        [self performSelector:@selector( move2) withObject:nil afterDelay:0.10];
        [self performSelector:@selector( move3) withObject:nil afterDelay:0.12];    
    }
    else 
    {
        [pTmpTimer invalidate];
        intTmp = 0;
    }
}

From above code, testMethod will call 20 times and according to your requirement your code will repeat 20 times..

Hope It works for you.

Happy coding..
