Automatic resizing of TableView?

Question

iOS

Tell me how to implement, if possible, then as detailed as possible, examples from stackoverflow do not work.
Dynamic cell resizing is implemented as
- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath {
CGSize size = [[[self vozvratmassiva] objectAtIndex:indexPath.row]
sizeWithFont:[UIFont systemFontOfSize:15]
constrainedToSize: CGSizeMake(260, CGFLOAT_MAX)];
double commonsize = size.height;
...
return commonsize;
}
Working without using storyboard

Answer 1

vozvratmassiva is a shame. As for the table, in order to change the size of the cell, it must be reloaded via reload of the cell or the entire table, without this nothing will happen.

Answer 2

What exactly are you having problems with?
If you have UITableView *tableView, then you can change its size by changing tableView.frame or tableView.bounds.
Accordingly, in the code you calculate the required table size and set it. In your case, as far as I understand, it should be equal to the sum of the heights of all cells?!
Well, here's a simple example that resizes a table on the click of a button.
1. We create an application with a single ViewController and xib file.
2. Add UITableView to xib.
3. Bind the table's delegate and dataSource properties to the File's Owner.
4. We create a @property tableView class and associate a table with it in our class.
5. Next, use this code: pastie.org/8800027
In the code, I am creating two buttons, one is zooming out the table and the other is zooming in.
