带有阴影的 UITableView

Question

I know how to add a shadow around UIViews and even to animate them when the views bounds change. However I've come across a view that is a little more tricky it seems. UITableView

Adding a shadow around this view is easy enough and even going by this example: Adding drop shadow to UITableView It works well. However my problem is that I need the shadow to go around the last cell in the UITableView and not it's bounds . So, top, sides and bottom would be the last cell in the UITableView .

Thinking about how it'd work leaves me to believe there is a better solution. Maybe if I was able to adjust the UitableView s frame based on the number of cells? However the cells are dynamic and I don't know their heights until runtime.

Any suggestions would greatly be appreciated.

Thanks!

Answer 1

something like...

- (void)tableView:(UITableView *)tableView willDisplayCell:(UITableViewCell *)cell forRowAtIndexPath:(NSIndexPath *)indexPath {
  if (indexPath.row == [self tableView:tableView numberOfRowsInSection:indexPath.section] - 1) {
    // last row
    cell.layer.shadowOpacity = 0.5;
    cell.layer.shadowPath = [UIBezierPath bezierPathWithRect:cell.bounds].CGPath;
    cell.layer.masksToBounds = NO;
  }
}

Only one option for your requirement :

1) Add shadow for top, left and right of UITableView .

2) Add shadow to bottom of last UITableViewCell . For this you might need to increase height of last cell of UITableView;
