objective-c TableView单元格动画

遵照代理方法后执行 -(void)tableView:(UITableView *)tableView willDisplayCell:(UITableViewCell *)cell forRowAtIndexPath:(NSIndexPath *)indexPath{

CATransform3D rotation;
rotation = CATransform3DMakeRotation( (90.0*M_PI)/180, 0.0, 0.7, 0.4);
rotation.m34 = 1.0/ -600;

cell.layer.shadowColor = [[UIColor blackColor]CGColor];
cell.layer.shadowOffset = CGSizeMake(10, 10);
cell.alpha = 0;
cell.layer.transform = rotation;
cell.layer.anchorPoint = CGPointMake(0, 0.4);


[UIView beginAnimations:@"rotation" context:NULL];
[UIView setAnimationDuration:0.5];
cell.layer.transform = CATransform3DIdentity;
cell.alpha = 1;
cell.layer.shadowOffset = CGSizeMake(0, 0);
[UIView commitAnimations];
