TableViewCell加动画

-(void)tableView:(UITableView *)tableView willDisplayCell:(UITableViewCell *)cell forRowAtIndexPath:(NSIndexPath *)indexPath{
    //1.
配置CATransform3D的内容
    CATransform3D transform;
    transform = CATransform3DMakeTranslation(50, 100, 0);
//    transform.m34 = 1.0/ -600;

    

    
    //2.
定义cell的初始状态
    cell.layer.shadowColor = [[UIColor blackColor]CGColor];
    cell.layer.shadowOffset = CGSizeMake(10, 10);
    cell.alpha = 0;

    
    cell.layer.transform = transform;
    cell.layer.anchorPoint = CGPointMake(0.5, 0.5);

    
    //3.
定义cell的最终状态，并提交动画
    [UIView beginAnimations:@"transform" context:NULL];
    [UIView setAnimationDuration:0.5];
    cell.layer.transform = CATransform3DIdentity;
    cell.alpha = 1;
    cell.layer.shadowOffset = CGSizeMake(0, 0);
    cell.frame = CGRectMake(0, cell.frame.origin.y, cell.frame.size.width, cell.frame.size.height);
    [UIView commitAnimations];
