    <p>I can't get my first UITableView to update with a setting made in a second UITableView.</p> <p>A user clicks a row in firstTableView causing secondTableView to be displayed. When the user selects a row, secondTableView disappears and firstTableView is reappears. However, the data isn't updated.</p> <p>I tried using the following in firstTableView:</p> <pre><code>- (void) viewWillAppear:(BOOL)animated { // (verified it's defenitely section 2, row 0 by logging it before and after...) // (also verified that the source data has been updated before viewWillAppear is called...) NSIndexPath *durPath = [NSIndexPath indexPathForRow:0 inSection:2]; NSArray *paths = [NSArray arrayWithObject:durPath]; [self.firstTableView reloadRowsAtIndexPaths:paths withRowAnimation:UITableViewRowAnimationNone]; // If I use some row animation, I can clearly see that the correct row is being animated, it's just not being updated. } </code></pre> <p>But the label does not update. Obviously I'm missing something. Both views are modal view controllers. </p> <p>Here's my cell construction:</p> <pre><code>- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *CellIdentifier = @"Cell"; UITableViewCell *cell = [firstTableView dequeueReusableCellWithIdentifier:CellIdentifier]; UILabel *myLabel = [[UILabel alloc] initWithFrame:CGRectMake(150.0, 15.0, 120.0, 17.0)]; myLabel.backgroundColor = [UIColor clearColor]; myLabel.font = [UIFont systemFontOfSize:14]; myLabel.textAlignment = UITextAlignmentLeft; static NSString* kConstants[] = {kOption0,kOption1,kOption2,kOption3,kOption4,kOption5,kOption6,kOption7,kOption8,kOption9,kOption10,nil}; if (cell == nil) { cell = [[[UITableViewCell alloc] initWithStyle: UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease]; if (indexPath.section == 2) { [cell addSubview:myLabel]; } } switch (indexPath.section) { case 0: // … deal with a bunch of UISwitches break; case 1: // … deal with section 1 stuff break; case 2: { NSLog(@"Verify that intType has in fact been changed here: %i, %@",intType, kConstants[intType]); // Even though intType and the constant string reflects the correct (updated) values when returning from secondTableView, myLabel.text does not change, ie: it's correct one line above, but not correct one line below. The myLabel.text is just not updating to the new value. myLabel.text = kConstants[intType]; cell.textLabel.text = @"Choose Some Value:"; cell.accessoryType = UITableViewCellAccessoryDetailDisclosureButton; } break; case 3: // … deal with section 3 stuff break; } [myLabel release]; return cell; } </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
