tableViewCell创建时添加一些动画

有时候因为项目的需要,给tableView添加一些动画:

cell.layer.transform = CATransform3DMakeScale(0.1, 0.1, 1);

[UIView animateWithDuration:0.25 animations:^{

cell.layer.transform = CATransform3DMakeScale(1, 1, 1);

}];

或者

- (void)collectionView:(UICollectionView *)collectionView willDisplayCell:(UICollectionViewCell *)cell forItemAtIndexPath:(NSIndexPath *)indexPath{

if (indexPath.row % 2 != 0) {

cell.transform = CGAffineTransformTranslate(cell.transform, ScreenWidth/2, 0);

}else{

cell.transform = CGAffineTransformTranslate(cell.transform, -ScreenWidth/2, 0);

}

cell.alpha = 0.0;

[UIView animateWithDuration:0.7 animations:^{

cell.transform = CGAffineTransformIdentity;

cell.alpha = 1.0;

} completion:^(BOOL finished) {

}];

}
