Can we animate multiple objects using a single timer?

Question

To animate multiple objects in a view, do we have to use seperate timers for each of the object?

Currently I have four objects for which I am using four timers. How can I do it using a single timer?

Thanks!

Answer 1

If you are animating at the same time then you should use four timers,else you can use single timer itself.

All the best.

Answer 2

If you are animating them all at once within the same time window you can do them together:

[UIView beginAnimations:@"anim1" context:nil];
[UIView setAnimationDuration:0.4];
[UIView setAnimationCurve:UIViewAnimationCurveEaseInOut];

object1.frame = newFrame1;
object2.frame = newFrame2;
object3.frame = newFrame3;
object4.frame = newFrame4;

[UIView commitAnimations];
