    <p>I want to store xml on the iphone that consists of a number of favourite items chosen by the user of the app. I am using TBXML (inherited from prev dev) and as such this cant write xml, I was thinking of chopping together the xml from each item as a string and then loading this in Like so:</p> <p>tbxml = [[TBXML alloc] initWithXMLString:myXML]</p> <p>This is not ideal but is there limitations / advice for this method and what would be the best place to store this file?</p> <p>Many thanks</p> <p>edit</p> <p>The user favourites an item in a UITableView, these can then be viewed in another UITableView called 'My Favourites'. The UITableViewController displays the content from an xml file returned from a server. I was trying to make things simple for me to effectively append each 'items' xml to a large string and then store that string somewhere - either in a file or in NSUserDefaults</p> <p>ideally I could save an array of objects as they are added to favourites to be read back in later.</p> <p>the objects are created like so</p> <pre><code>@interface Playlist : NSObject { NSURL *imagePath; NSString *title; NSString *subTitle; NSString *mediaType; NSString *artistName; NSString *id; } @property (nonatomic, retain) NSURL *imagePath; @property (nonatomic, retain) NSString *title; @property (nonatomic, retain) NSString *subTitle; @property (nonatomic, retain) NSString *mediaType; @property (nonatomic, retain) NSString *artistName; @property (nonatomic, retain) NSString *id; @end </code></pre> <p>is there a way of saving an array of objects like the one above in NSUserDefaults?</p> <p>thanks</p> <p>EDIT 2 I went with NSUserDefaults and maintained an ID for each item as an array</p> <p>very easy to access and update, I made a PlaylistDataController class with methods in there like this one to add an item to my 'MyPlaylistArray' in the user defaults</p> <pre><code>-(void) addItemToPlaylist: (NSString*) myID { NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults]; NSMutableArray *myPlaylistArray = [NSMutableArray arrayWithArray:[defaults objectForKey:@"MyPlaylistArray"]]; [myPlaylistArray addObject:myID]; [defaults setObject:myPlaylistArray forKey:@"MyPlaylistArray"]; [defaults synchronize]; } </code></pre> <p>Hope it helps someone</p>

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.
