tableview cell添加3D动画
当cell显示之前,会先调用该方法,因此给cell添加动画,在这个方法里面即可。
-(void)tableView:(UITableView *)tableView willDisplayCell:(UITableViewCell *)cell forRowAtIndexPath:(NSIndexPath *)indexPath{
// 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];
}
