    <p>i have a uitableview with a method fetch list that runs every 5 secs. when there is updated data in the core data for that record, the fetch list method does not update the latest into its array. thus, when i reload the data, it always shows the "old" record. </p> <p>i call this method, followed by a reload data on the uitableview.</p> <p>this is my fetch list method:</p> <pre><code>- (void) fetchList:(int) listNo{ // Define our table/entity to use self.marketWatchListArray = nil; NSEntityDescription *entity = [NSEntityDescription entityForName:@"Market_watch" inManagedObjectContext:context]; // Setup the fetch request NSFetchRequest *request = [[NSFetchRequest alloc] init]; [request setEntity:entity]; Mobile_TradingAppDelegate *appDelegate = (Mobile_TradingAppDelegate *)[[UIApplication sharedApplication] delegate]; NSPredicate *getList = [NSPredicate predicateWithFormat:@"(list_id == %d) AND (userID == %@)", listNo, appDelegate.user_number]; [request setPredicate:getList]; NSSortDescriptor *sortByName = [[NSSortDescriptor alloc] initWithKey:@"stockName" ascending:YES]; [request setSortDescriptors:[NSArray arrayWithObject:sortByName]]; // Fetch the records and handle an error NSError *error; NSMutableArray *mutableFetchResults = [[context executeFetchRequest:request error:&amp;error] mutableCopy]; if (!mutableFetchResults) { // Handle the error. // This is a serious error and should advise the user to restart the application } // Save our fetched data to an array [self setMarketWatchListArray: mutableFetchResults]; [mutableFetchResults release]; [request release]; </code></pre> <p>}</p> <p>strange thing is the table does not update with the latest when the timer runs fetchlist:1. When i swap to fetchlist:2, then back to fetchlist:1, the table is updated with the latest. </p> <p>I have a segmentcontrol to toggle between different list.</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.
