Resize UITableView's height to be as high as it needs to fit only total content size

ios, ios5, ios6, objective-c, uitableview

Solution

if I understand it correctly, you should be able to add up the height for each row and adjust the tableview height based on that:

CGFloat tableHeight = 0.0f;
for (int i = 0; i < [_stepsArray count]; i ++) {
    tableHeight += [self tableView:self.tableView heightForRowAtIndexPath:[NSIndexPath indexPathForRow:i inSection:0]];
}
self.tableView.frame = CGRectMake(self.tableView.frame.origin.x, self.tableView.frame.origin.y, self.tableView.frame.size.width, tableHeight);

you can do this immediately after [tableView reloadData]

Problem

So I am having a very basic issue. I have this `UITableView` within a `view`, and I would like to make this table's height as high as it needs to be to display ALL the rows within the table. Therefore, I don't want to be able to scroll, I just want all the rows to appear. (The rows are dynamic in quantity and `height`). ``` -(CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath { CGSize cellSize = [[[_stepsArray objectAtIndex:indexPath.row]content] sizeWithFont:[UIFont boldSystemFontOfSize:18.0f] constrainedToSize:CGSizeMake(528.0f, CGFLOAT_MAX)lineBreakMode:NSLineBreakByWordWrapping]; return cellSize.height; } ``` If there are 20 rows, the table will be very high, but if there is only 1 row, it will be very small and the other content will not appear 19 rows below.
