    <p>I am trying to pass an array of float data to a table view but didn't manage to get it working. Currently I am just passing an array with text to be displayed, which was based on an example. Ideally I would like to use the result of calculations being put into an array to fill the table view. What would you suggest to accomplish this task?</p> <p><strong>Button</strong></p> <pre><code>-(IBAction) selectDate:(id)sender; { if ( [[[sender titleLabel] text] isEqualToString:@"Set Start Date"]) { startDate = [pickerDate date]; [startDate retain]; NSDateFormatter *dateFormat = [[NSDateFormatter alloc] init]; [dateFormat setDateFormat:@"yy"]; labelStartDate.text = [dateFormat stringFromDate:startDate]; [dateFormat release]; //buttonDateStart.enabled = NO; } if ( [[[sender titleLabel] text] isEqualToString:@"Set End Date"]) { endDate = [pickerDate date]; [endDate retain]; NSDateFormatter *dateFormat = [[NSDateFormatter alloc] init]; [dateFormat setDateFormat:@"yy"]; labelEndDate.text = [dateFormat stringFromDate:endDate]; </code></pre> <p><strong>Data being used</strong></p> <pre><code>- (void)viewDidLoad { NSDictionary *row1 = [[NSDictionary alloc] initWithObjectsAndKeys: @"MacBook" , @"Name",@"White",@"Color",nil]; NSDictionary *row2 = [[NSDictionary alloc] initWithObjectsAndKeys: @"MacBook pro",@"Name",@"Silver",@"Color",nil]; NSDictionary *row3 = [[NSDictionary alloc] initWithObjectsAndKeys: @"iMac",@"Name",@"White",@"Color",nil]; NSArray *array = [[NSArray alloc] initWithObjects: row1,row2,row3, nil]; self.computers = array; [row1 release]; [row2 release]; [row3 release]; </code></pre> <p><strong>Table</strong></p> <pre><code>-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section { return[self.computers count]; } -(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *CellTableIdentifier = @"CellTableIdentifier"; UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellTableIdentifier]; if(cell == nil){ CGRect cellFrame = CGRectMake(0,0,300,65); cell = [[[UITableViewCell alloc] initWithFrame: cellFrame reuseIdentifier:CellTableIdentifier] autorelease]; //create the 2 rows CGRect nameLabelRect = CGRectMake(0,5,70,15); UILabel *nameLabel = [[UILabel alloc] initWithFrame:nameLabelRect]; nameLabel.textAlignment = UITextAlignmentRight; nameLabel.text = @"Date:"; nameLabel.font = [UIFont boldSystemFontOfSize:12]; [cell.contentView addSubview: nameLabel]; [nameLabel release]; CGRect colorLabelRect = CGRectMake(0,26,70,15); UILabel *colorLabel = [[UILabel alloc] initWithFrame:colorLabelRect]; nameLabel.textAlignment = UITextAlignmentRight; colorLabel.text = @"Amount:"; colorLabel.font = [UIFont boldSystemFontOfSize:12]; [cell.contentView addSubview: colorLabel]; [colorLabel release]; CGRect nameValueRect = CGRectMake(80,5,200,15); UILabel *nameValue = [[UILabel alloc] initWithFrame:nameValueRect]; nameValue.tag = kNameValueTag; [cell.contentView addSubview:nameValue]; [nameValue release]; CGRect colorValueRect = CGRectMake(80,25,200,15); UILabel *colorValue = [[UILabel alloc] initWithFrame:colorValueRect]; colorValue.tag = kColorValueTag; [cell.contentView addSubview:colorValue]; [colorValue release]; } //Data source NSUInteger row = [indexPath row]; NSDictionary *rowData = [self.computers objectAtIndex:row]; UILabel *name = (UILabel *)[cell.contentView viewWithTag:kNameValueTag]; name.text = [rowData objectForKey:@"Name"]; UILabel *color = (UILabel *)[cell.contentView viewWithTag:kColorValueTag]; color.text = [rowData objectForKey:@"Color"]; 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.
