    <p>I'm having an issue that the dictionary <code>timeStamps</code> changes all the values to <code>null</code>. The keys are all fine, even if I switch what was a key to a value and vice versa. No matter the order, the values end up as <code>null</code> and the keys end up exactly as they should.</p> <p>Here's the code. It's an xml parser. It is building a dictionary that has an array of codes for keys and an array of timestamps for values. The keys and values are parallel arrays representing categories. </p> <p>All variables are allocated and initiated elsewhere. This imports the header file that has all of these variables as properties. <code>@property (strong, nonatomic) Type variableName;</code> then in the main file it has the line <code>@synthesize variableName</code>. Also, it has <code>variableName = [[Type alloc] init];</code>. Thank you everybody for your help!</p> <pre><code>- (void) didStartElement (elementname is passed as xml tag) { //Tells us if we are in the dance categories if ([elementName isEqualToString:@"categories"]) { isCategory = YES; // Just tells us we're ready to start reading } else if ([elementName isEqualToString:@"category"] &amp;&amp; isCategory) { onCategory = YES; // } } - (void) foundCharacters (currentNodeContent is the info between tags) { currentNodeContent = (NSMutableString *) string; } - (void) didEndElement { // if leaving dance categories if ([elementName isEqualToString:@"Category End"]) { isCategory = NO; // We've left a category } else if ([elementName isEqualToString:@"code"] &amp;&amp; onCategory) { Code = currentNodeContent; currentNodeContent = nil; isWaitingForTime = YES; } else if ([elementName isEqualToString:@"time"] &amp;&amp; isWaitingForTime) { [runningList addObject:Code]; [runningList addObject:currentNodeContent]; isWaitingForTime = NO; currentNodeContent = nil; Code = @""; } else if ([elementName isEqualToString:@"dances"]) { [timeStamps setObject:runningTimeList forKey:runningList]; [runningTimeList removeAllObjects]; [runningList removeAllObjects]; } } </code></pre>

    2. COAs background, why are you using *arrays* of strings as both your key and value types? Or do you want them just to be strings?

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.
