UICollectionViewCell Shake

Question

I have created a UICollectionView and would like to have all the cells shake like the edit mode of the springboard on the iPhone. I have created my shake code but don\'t kno

Answer 1

If you put you're code in a method called startJiggling in your custom cell, then you could call this method in your controller:

[self.collectionView.visibleCells makeObjectsPerformSelector:@selector(startJiggling)];

That ensures that all visible cells will start jiggling.

Then I'd also set some flag indicating that your cells should jiggle and test for that in collectionView:cellForItemAtIndexPath:. If YES, then call your method.
