UITableView上下拖动动画

-(void)tableView:(UITableView*)tableView willDisplayCell:(UITableViewCell*)cell forRowAtIndexPath:(NSIndexPath*)indexPath{

    // 1. 配置CATransform3D的内容

    CATransform3Dtransform;

    transform =CATransform3DMakeRotation( (90.0*M_PI)/180,0.0,0.7,0.4);

    transform.m34=1.0/ -600;



    // 2. 定义cell的初始状态

    cell.layer.shadowColor= [[UIColorblackColor]CGColor];

    cell.layer.shadowOffset=CGSizeMake(10,10);

    cell.alpha=0;



    cell.layer.transform= transform;

    cell.layer.anchorPoint=CGPointMake(0,0.5);



    // 3. 定义cell的最终状态，并提交动画

    [UIView beginAnimations:@"transform" context:NULL];
