    <p><br>I have two little problems with my UIScrollView. <br>I managed to create scroll view, which is similar to the picker view except that it's horizontal.<br> <br><strong>The problem n.1</strong> is - How do I get the number which the user tapped? <br><strong>The problem n.2</strong> is - How do I make the scrollview to go round and round - never-ending? <br><strong>A question</strong> - Is it possible to make some "selection indicator"?</p> <p>Here is my code:</p> <blockquote> <p>numberArray = [NSArray arrayWithObjects:@"1", @"2", @"3", @"4", @"5", @"6", @"7", @"8", @"9", @"10", @"11", @"12", @"13", @"14", @"15", @"16", @"17", @"18", @"19", @"20", @"21", @"22", @"23", @"24", @"25", @"26", @"27", @"28", @"29", @"30", @"31", @"32", @"33", @"34", @"35", @"36", @"37", @"38", @"39", @"40", @"41", @"42", @"43", @"44", @"45", @"46", @"47", @"48", @"49", @"50", @"51", @"52", @"53", @"54", @"55", @"56", @"57", @"58", @"59", @"60", @"61", @"62", @"63", @"64", @"65", @"66", @"67", @"68", @"69", @"70", @"71", @"72", @"73", @"74", @"75", @"76", @"77", @"78", @"79", @"80", @"81", @"82", @"83", @"84", @"85", @"86", @"87", @"88", @"89", @"90", @"91", @"92", @"93", @"94", @"95", @"96", @"97", @"98", @"99", @"100", nil];</p> <pre><code>masterDividerView = [[UIView alloc] initWithFrame:CGRectMake(0, 480, 320, 44)]; morePeople = [[UIScrollView alloc] initWithFrame:CGRectMake(0, 0, 320, 53)]; morePeople.backgroundColor = [UIColor scrollViewTexturedBackgroundColor]; morePeople.delegate = self; [morePeople setBackgroundColor:[UIColor whiteColor]]; [morePeople setCanCancelContentTouches:NO]; morePeople.showsHorizontalScrollIndicator = NO; morePeople.showsVerticalScrollIndicator = NO; morePeople.clipsToBounds = NO; morePeople.scrollEnabled = YES; morePeople.pagingEnabled = NO; NSUInteger nimages = 0; NSInteger tot=0; CGFloat cx = 0; for (; ; nimages++) { NSString *label = [numberArray objectAtIndex:nimages]; if (tot==99) { break; } if (99==nimages) { nimages=0; } UILabel *labelView = [[UILabel alloc] init]; labelView.text = label; labelView.lineBreakMode = UILineBreakModeWordWrap; labelView.numberOfLines = 0; [labelView sizeToFit]; labelView.backgroundColor = [UIColor scrollViewTexturedBackgroundColor]; CGRect rect = labelView.frame; rect.size.height = 53; rect.size.width = 40; rect.origin.x = cx; rect.origin.y = 0; labelView.frame = rect; [morePeople addSubview:labelView]; cx += labelView.frame.size.width+5; tot++; } self.pageControl.numberOfPages = nimages; [morePeople setContentSize:CGSizeMake(cx, [morePeople bounds].size.height)]; [masterDividerView addSubview:morePeople]; [self.view addSubview:masterDividerView]; </code></pre> </blockquote> <p>If anybody knows a good solution to this, I would be very happy!!!! :)) <br></p>

    1. COI think it would be much nicer to create `numberArray` like so: `NSMutableArray *numberArray = [[NSMutableArray alloc] init]; for (int i = 0; i < 100; i++) { [numberArray addObject:[NSString stringWithFormat:@"%i", i]]; }`

Querying!

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.
