给tableview Cell添加动画(两种实现方法 效果还不错)

TableViewController有一个代理方法就是下面的方法

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

*)indexPath{

//第一种效果

#pragma mark - UITableView delegate methods
- (void)tableView:(UITableView *)tableView willDisplayCell:(UITableViewCell *)cell forRowAtIndexPath:(NSIndexPath *)indexPath
{
    /*
    CGFloat rotationAngleDegrees = 0;
    CGFloat rotationAngleRadians = rotationAngleDegrees * (M_PI/180);
    CGPoint offsetPositioning = CGPointMake(-200, -20);
    CATransform3D transform = CATransform3DIdentity;
    transform = CATransform3DRotate(transform, rotationAngleRadians, 0.0, 0.0, 1.0);
    transform = CATransform3DTranslate(transform, offsetPositioning.x, offsetPositioning.y, 0.0);
    
    
    UIView *card = [cell contentView];
    card.layer.transform = transform;
    card.layer.opacity = 1;
    
    
    
    [UIView animateWithDuration:0.8f animations:^{
        card.layer.transform = CATransform3DIdentity;
        card.layer.opacity = 1;
    }];

    */

//第二种效果

    // 1. 配置CATransform3D的内容
    CATransform3D transform;    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 = [[UIColor blackColor]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]; 

  [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];

}
