    <p>I'm trying to import a large data set (~6,000) in to my core data application. I've read the Apple document "Efficiently Importing Data" and I think I set it up correctly. The weird thing is the application isn't crashing in the simulator, although it does if I run it with the Leaks instrument, but it isn't saving all the data. Sometimes it will only save 3-4 hundred other times it will save 3-4 thousand and rarely the whole data set. I think it's probably memory leak related and I'm pretty new to using NSAutoReleasePool, any help would be much appreciated.</p> <pre><code> NSURL *url = [NSURL URLWithString:@""]; NSString *responseString = [NSString stringWithContentsOfURL:url encoding:NSASCIIStringEncoding error:nil]; if (responseString) { NSArray *players = [responseString componentsSeparatedByString:@";"]; NSUInteger LOOP_LIMIT = 100, count = 0; NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init]; NSManagedObjectContext *context = [[AppController sharedAppController] managedObjectContext]; [context setUndoManager:nil]; for (int i=0; i&lt;([players count] - 1); i++) { NSArray *info = [[players objectAtIndex:i] componentsSeparatedByString:@","]; NSString *dateInfo = [info objectAtIndex:10]; NSLocale *usLocale = [[[NSLocale alloc] initWithLocaleIdentifier:@"en_US"] autorelease]; NSDateFormatter *fo = [[[NSDateFormatter alloc] init] autorelease]; [fo setDateFormat:@"MM/dd/yyyy"]; [fo setLocale:usLocale]; [fo setTimeZone:[NSTimeZone systemTimeZone]]; NSDate *dob = [fo dateFromString:dateInfo]; Players *player = [NSEntityDescription insertNewObjectForEntityForName:@"Players" inManagedObjectContext:context]; NSNumberFormatter *f = [[[NSNumberFormatter alloc] init] autorelease]; [f setNumberStyle:NSNumberFormatterNoStyle]; player.playerID = [f numberFromString:[info objectAtIndex:0]]; player.lastName = [info objectAtIndex:1]; player.firstName = [info objectAtIndex:2]; player.position = [info objectAtIndex:4]; NSString *teamName = [info objectAtIndex:3]; NSFetchRequest *req = [[[NSFetchRequest alloc] init] autorelease]; NSEntityDescription *ent = [NSEntityDescription entityForName:@"Teams" inManagedObjectContext:context]; [req setEntity:ent]; [req setIncludesPropertyValues:NO]; NSPredicate *pre = [NSPredicate predicateWithFormat:@"team=%@", teamName]; [req setPredicate:pre]; NSArray *list = [context executeFetchRequest:req error:nil]; if ([list count]) { Teams *team = [list objectAtIndex:0]; player.team_Players_Teams = team; } count++; if (count == LOOP_LIMIT) { [context save:nil]; [context reset]; [pool drain]; pool = [[NSAutoreleasePool alloc] init]; count = 0; } } if (count != 0) { NSLog(@"In Save Remaining"); [context save:nil]; [context reset];[pool drain]; } </code></pre>

    2. COTrue - I just added that but that shouldn't be affecting the actual import. There still has to be some error in the import process.

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.
