color animation help

[tackey123]

I am following this tutorial on youtube: YouTube - iPhone SDK Tutorial - How to Make an Animation (with different images)
And my question is, how do you make four different buttons change the duration of the animation? So you click on button one and it sets the duration to a certain time depending on what button you pressed (i.e. 1.75 seconds).
Or say you press button three then it sets the animation duration to 0.5 seconds then stars the animation.
If someone could post some code or some help that would be great, thanks!

float duration;
color.animationDuration = duration;

Now, when you press one of the buttons, make sure it changes the value of "duration" to however long you want it to be.

How do you set the value of each button? thanks

And where do you put the code?

Not sure what you're asking since I did not watch the whole tutorial, just maybe 20 seconds of it total.

You want to create 4 buttons with each button changing the value of "duration" to whatever length of animation you what.
I'd assume you'd put the code in touchesBegan method if you're using custom buttons or if you're using UIButtons, in the method the UIButton calls once tapped.
