How to dynamically set the height of a UITableView?

Question

I have a tableview with different cell heights using the heightForRowAtIndexPath: method.

I would like to dynamically set the height of a UITable

Answer 1

Add an observer for the contentSize property on the table view, and adjust the frame accordingly

[self.tableView addObserver:self forKeyPath:@"contentSize" options:0 context:NULL];

then in the callback:

- (void)observeValueForKeyPath:(NSString *)keyPath ofObject:(id)object change:(NSDictionary *)change context:(void *)context
{
    CGRect frame = self.tableView.frame;
    frame.size = self.tableView.contentSize;
    self.tableView.frame = frame;
}
