iOS How to Animate UIButtons in specific Direction?

[Shazad]

I have 10 UIButtons in my application. Now i want to move all these UIButtons with a little gap between all these from the point ( x=-10; y=260; ) to final point ( x=490; y=260; ) landscape view point. I know all these type of animation perform using UIView Code Animation Block or Simple UIView Animation. But I have some concern when using these method to perform animation on UIButtons.

• 
  How to create gape between these UIButtons beacuse all these Buttons have same starting point.

• When any UIButton Touch the end point (that i define above ) how this UIButton again start animation immediately from the Starting point (that i define above ).

• IF Some of UIButton deleted during animation (for this delation one of the fuction i have in my application) then the UIButton which follow the Deleted UIButton change the location and get the deleted UIButtons location.

• How to perform these UIButtons animation Continiously untill the last UIButtons present on the Screen.

And last thing I want that my

• Animation get start as my view load.

From Till now i try this way.

- (void)moveToLeft:(NSString *)animationID finished:(NSNumber *)finished context:(void *)context {
btn1.hidden=YES;
btn2.hidden=YES;
btn3.hidden=YES;
btn4.hidden=YES;
btn5.hidden=YES;
[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:0.0];
[UIView setAnimationDelay:0.0];
[UIView setAnimationCurve:UIViewAnimationCurveEaseInOut];
[UIView setAnimationDelegate:self];
[UIView setAnimationDidStopSelector:@selector(faceRight:finished:context:)];
btn1.center = CGPointMake(-370, 260);
btn2.center = CGPointMake(-290, 260);
btn3.center = CGPointMake(-210, 260);
btn4.center = CGPointMake(-130, 260);
btn5.center = CGPointMake(-50, 260);
[UIView commitAnimations];
}

- (void)faceRight:(NSString *)animationID finished:(NSNumber *)finished context:(void *)context {
[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:0.0];
[UIView setAnimationDelay:0.0];
[UIView setAnimationCurve:UIViewAnimationCurveEaseInOut];
[UIView setAnimationDelegate:self];
[UIView setAnimationDidStopSelector:@selector(moveToRight:finished:context:)];
btn1.transform = CGAffineTransformMakeRotation(0);
btn2.transform = CGAffineTransformMakeRotation(0);
btn3.transform = CGAffineTransformMakeRotation(0);
btn4.transform = CGAffineTransformMakeRotation(0);
btn5.transform = CGAffineTransformMakeRotation(0);
[UIView commitAnimations];
}
- (void)moveToRight:(NSString *)animationID finished:(NSNumber *)finished context:(void *)context {
btn1.hidden=NO;
btn2.hidden=NO;
btn3.hidden=NO;
btn4.hidden=NO;
btn5.hidden=NO;
[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:20.0];
[UIView setAnimationDelay:0.0];
[UIView setAnimationDelegate:self];
[UIView setAnimationCurve:UIViewAnimationCurveEaseInOut];
[UIView setAnimationDidStopSelector:@selector(faceLeft:finished:context:)];
btn1.center = CGPointMake(490, 260);
btn2.center = CGPointMake(590, 260);
btn3.center = CGPointMake(690, 260);
btn4.center = CGPointMake(790, 260);
btn5.center = CGPointMake(890, 260);
[UIView commitAnimations];
 }
- (void)faceLeft:(NSString *)animationID finished:(NSNumber *)finished context:(void *)context {

[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:0.0];
[UIView setAnimationDelay:0.0];
[UIView setAnimationDelegate:self];
[UIView setAnimationCurve:UIViewAnimationCurveEaseInOut];
[UIView setAnimationDidStopSelector:@selector(moveToLeft:finished:context:)];
btn1.transform = CGAffineTransformMakeRotation(M_PI);
btn2.transform = CGAffineTransformMakeRotation(M_PI);
btn3.transform = CGAffineTransformMakeRotation(M_PI);
btn4.transform = CGAffineTransformMakeRotation(M_PI);
btn5.transform = CGAffineTransformMakeRotation(M_PI);
[UIView commitAnimations];
 }
- (void)viewDidLoad {

[self moveToLeft:nil finished:nil context:nil];

[super viewDidLoad];
 }

But Still need a lot of work to make its according to above Creteria.

Any help will be appreciated. Thanx in Advance.
