在willDisplayCell方法中给cell加动画
- (void)tableView:(UITableView *)tableView willDisplayCell:(UITableViewCell *)cell forRowAtIndexPath:(NSIndexPath *)indexPath{
NSArray *arr = tableView.indexPathsForVisibleRows;
NSIndexPath *firstIndexPath = arr[0];
cell.layer.anchorPoint = CGPointMake(0, 0.5);
cell.layer.position = CGPointMake(0, cell.layer.position.y);
if (firstIndexPath.row < indexPath.row) {
cell.layer.transform = CATransform3DMakeRotation(M_PI_4, 0, 0, 1.0);
}else{
cell.layer.transform = CATransform3DMakeRotation(-M_PI_4, 0, 0, 1.0);
}
cell.alpha = 0.0;
[UIView animateWithDuration:1 animations:^{
cell.layer.transform = CATransform3DIdentity;
cell.alpha = 1.0;
}];
}
