推荐答案
//Objective c
- (CGSize)collectionView:(UICollectionView *)collectionView layout:(UICollectionViewLayout*)collectionViewLayout sizeForItemAtIndexPath:(NSIndexPath *)indexPath {
return CGSizeMake((collectionView.frame.size.width/3)-20, 100);
}
// Swift 2.0
func collectionView(collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, sizeForItemAtIndexPath indexPath: NSIndexPath) -> CGSize {
return CGSizeMake((collectionView.frame.size.width / 3) - 20, 100)
}
// Swift 3.0
override func collectionView(_ collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, sizeForItemAt indexPath: IndexPath) -> CGSize {
return CGSize(width: CGFloat((collectionView.frame.size.width / 3) - 20), height: CGFloat(100))
}
