animate each object in an array one after the other with a slight delay.

[aldcorn@live.com]

Hi guys,
I was hoping to find a way to animate each object of an array of uiviews one after another like the crowd doing the wave at a stadium.

My array is set up and I am currently able to get one or all of the objects to animate but I have no idea how to get the object a index 0 to jump, and then the object at index 1 to jump, and so on with a slight delay after each one.


This is the code I currently have that allows me to have one object from the array pulse based on the object at index helloInt. I have tried various ++ ideas but unfortunately for me I am not very proficient in object c and my google searches have not given me what I want (probably don't know what I am searching for I guess)

- (void) pulse {
		currentView.transform = CGAffineTransformMakeScale(0.6, 0.6);
		[UIView beginAnimations:nil context:nil];
		[UIView setAnimationDuration:0.2];
		[UIView setAnimationDelegate:self];
		currentView.transform = CGAffineTransformMakeScale(0.5, 0.5);
		currentView.transform = CGAffineTransformMakeScale(1.3, 1.3);
		currentView.transform = CGAffineTransformMakeScale(1.0, 1.0);
		[UIView commitAnimations];
	UIButton *popButton = [arrayPlayer1btns objectAtIndex:helloInt];
	currentView = popButton;
	popButton.highlighted = YES;
		}

Here is some code I use with the array I am talking about. Here I am hiding certain objects in the array based on whether they are above or below a certain int.

-(IBAction)hideMyButtons:(id)sender {
	NSLog(@"hideMyButtons Array is: %@",arrayPlayer1btns);

	for (int i=0; i< [arrayPlayer1btns count]; i++){
			UIButton *button = [arrayPlayer1btns objectAtIndex:i];
			BOOL shouldHide = (i>(addThisToA + previousScoreA));
			NSLog(@"button:%x shouldHide:%d",button, shouldHide);
			button.hidden=shouldHide;
			currentView = button;

	}

EDIT:
i don't need help with the animation aspect, more specifically I would like help with iteration through the array I guess.

Hopefully I explained my question clearly. If anyone out there has the time any help would be appreciated.

Thanks,

I wonder if this code will help explain what I am trying to achieve.

- (void) pulseCelebrate {
	for (int i=0; i< [arrayPlayer1btns count]; i++){
		UIButton *buttonCelebrate = [arrayPlayer1btns objectAtIndex:i];

//if I use the following every other item pulses
//UIButton *buttonCelebrate = [arrayPlayer1btns objectAtIndex:i++];
		
        currentView = buttonCelebrate;
	currentView.transform = CGAffineTransformMakeScale(0.6, 0.6);
	[UIView beginAnimations:nil context:nil];
	[UIView setAnimationDuration:0.2];
	[UIView setAnimationRepeatCount:1e100f];
	[UIView setAnimationDelegate:self];
	currentView.transform = CGAffineTransformMakeScale(0.5, 0.5);
	currentView.transform = CGAffineTransformMakeScale(1.3, 1.3);
	currentView.transform = CGAffineTransformMakeScale(1.0, 1.0);
	[UIView commitAnimations];
	}}

What this code does: It repeatedly scales my array of uibuttons once they are set as the currentView in a pulsing manner. This code pulses all 100 of my array objects at once. I would somehow like to have the objects animate this way but I would ALSO like to have them start at slightly incremented times. I guess even random times would be ok if that is easier.

Am I looking at using an NSTimer or am I trying to do something that I shouldn't do?

Thanks for taking the time to look at this,

Rob

I think you can use the setAnimationDelay: method to set a delay before the animation begins.

So maybe you could add a line like:

[UIView setAnimationDelay:(i * 0.1)];

to add a 100 ms delay between the beginning of each animation.

Thanks very much. I was hoping it was going to be one line of code!

I appreciate your help. Here is my current code for animating an array of uibuttons that are then set as the current view and animated. There are two animations going here and I am going to tweak them for my purposes but thanks for helping me out.

Cheers,
Rob
