• How do I release an object allocated in a different AutoReleasePool ?

  - by ajcaruana

  Hi, I have a problem with the memory management in Objective-C. Say I have a method that allocates an object and stores the reference to this object as a member of the class. If I run through the same function a second time, I need to release this first object before creating a new one to replace it. Supposing that the first line of the function is: NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init]; This means that a different auto-release pool will be in place. The code to allocate the object is as follows: if (m_object != nil) [m_object release]; m_object = [[MyClass alloc] init]; [m_object retain]; The problem is that the program crashes when running the last line of the method: [pool release]; What am I doing wrong ? How can I fix this ? Regards Alan

• Custom Section Name Crashing NSFetchedResultsController

  - by Mike H.

  I have a managed object with a dueDate attribute. Instead of displaying using some ugly date string as the section headers of my UITableView I created a transient attribute called "category" and defined it like so: - (NSString*)category { [self willAccessValueForKey:@"category"]; NSString* categoryName; if ([self isOverdue]) { categoryName = @"Overdue"; } else if ([self.finishedDate != nil]) { categoryName = @"Done"; } else { categoryName = @"In Progress"; } [self didAccessValueForKey:@"category"]; return categoryName; } Here is the NSFetchedResultsController set up: NSFetchRequest *fetchRequest = [[NSFetchRequest alloc] init]; NSEntityDescription *entity = [NSEntityDescription entityForName:@"Task" inManagedObjectContext:managedObjectContext]; [fetchRequest setEntity:entity]; NSMutableArray* descriptors = [[NSMutableArray alloc] init]; NSSortDescriptor *dueDateDescriptor = [[NSSortDescriptor alloc] initWithKey:@"dueDate" ascending:YES]; [descriptors addObject:dueDateDescriptor]; [dueDateDescriptor release]; [fetchRequest setSortDescriptors:descriptors]; fetchedResultsController = [[NSFetchedResultsController alloc] initWithFetchRequest:fetchRequest managedObjectContext:managedObjectContext sectionNameKeyPath:@"category" cacheName:@"Root"]; The table initially displays fine, showing the unfinished items whose dueDate has not passed in a section titled "In Progress". Now, the user can tap a row in the table view which pushes a new details view onto the navigation stack. In this new view the user can tap a button to indicate that the item is now "Done". Here is the handler for the button (self.task is the managed object): - (void)taskDoneButtonTapped { self.task.finishedDate = [NSDate date]; } As soon as the value of the "finishedDate" attribute changes I'm hit with this exception: 2010-03-18 23:29:52.476 MyApp[1637:207] Serious application error. Exception was caught during Core Data change processing: no section named 'Done' found with userInfo (null) 2010-03-18 23:29:52.477 MyApp[1637:207] *** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'no section named 'Done' found' I've managed to figure out that the UITableView that is currently hidden by the new details view is trying to update its rows and sections because the NSFetchedResultsController was notified that something changed in the data set. Here's my table update code (copied from either the Core Data Recipes sample or the CoreBooks sample -- I can't remember which): - (void)controllerWillChangeContent:(NSFetchedResultsController *)controller { [self.tableView beginUpdates]; } - (void)controller:(NSFetchedResultsController *)controller didChangeObject:(id)anObject atIndexPath:(NSIndexPath *)indexPath forChangeType:(NSFetchedResultsChangeType)type newIndexPath:(NSIndexPath *)newIndexPath { switch(type) { case NSFetchedResultsChangeInsert: [self.tableView insertRowsAtIndexPaths:[NSArray arrayWithObject:newIndexPath] withRowAnimation:UITableViewRowAnimationFade]; break; case NSFetchedResultsChangeDelete: [self.tableView deleteRowsAtIndexPaths:[NSArray arrayWithObject:indexPath] withRowAnimation:UITableViewRowAnimationFade]; break; case NSFetchedResultsChangeUpdate: [self configureCell:[self.tableView cellForRowAtIndexPath:indexPath] atIndexPath:indexPath]; break; case NSFetchedResultsChangeMove: [self.tableView deleteRowsAtIndexPaths:[NSArray arrayWithObject:indexPath] withRowAnimation:UITableViewRowAnimationFade]; // Reloading the section inserts a new row and ensures that titles are updated appropriately. [self.tableView reloadSections:[NSIndexSet indexSetWithIndex:newIndexPath.section] withRowAnimation:UITableViewRowAnimationFade]; break; } } - (void)controller:(NSFetchedResultsController *)controller didChangeSection:(id <NSFetchedResultsSectionInfo>)sectionInfo atIndex:(NSUInteger)sectionIndex forChangeType:(NSFetchedResultsChangeType)type { switch(type) { case NSFetchedResultsChangeInsert: [self.tableView insertSections:[NSIndexSet indexSetWithIndex:sectionIndex] withRowAnimation:UITableViewRowAnimationFade]; break; case NSFetchedResultsChangeDelete: [self.tableView deleteSections:[NSIndexSet indexSetWithIndex:sectionIndex] withRowAnimation:UITableViewRowAnimationFade]; break; } } - (void)controllerDidChangeContent:(NSFetchedResultsController *)controller { [self.tableView endUpdates]; } I put breakpoints in each of these functions and found that only controllerWillChange is called. The exception is thrown before either controller:didChangeObject:atIndexPath:forChangeType:newIndex or controller:didChangeSection:atIndex:forChangeType are called. At this point I'm stuck. If I change my sectionNameKeyPath to just "dueDate" then everything works fine. I think that's because the dueDate attribute never changes whereas the category will be different when read back after the finishedDate attribute changes. Please help! UPDATE: Here is my UITableViewDataSource code: - (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView { return [[self.fetchedResultsController sections] count]; } - (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section { id <NSFetchedResultsSectionInfo> sectionInfo = [[self.fetchedResultsController sections] objectAtIndex:section]; return [sectionInfo numberOfObjects]; } - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *CellIdentifier = @"Cell"; UITableViewCell *cell = [self.tableView dequeueReusableCellWithIdentifier:CellIdentifier]; if (cell == nil) { cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease]; } [self configureCell:cell atIndexPath:indexPath]; return cell; } - (NSString *)tableView:(UITableView *)tableView titleForHeaderInSection:(NSInteger)section { id <NSFetchedResultsSectionInfo> sectionInfo = [[self.fetchedResultsController sections] objectAtIndex:section]; return [sectionInfo name]; }

• Textures loaded with NSOperation are blank

  - by Omega

  So I call this method: -(void)beginExecution { NSOperationQueue *queue = [NSOperationQueue new]; NSInvocationOperation *operation = [[NSInvocationOperation alloc] initWithTarget:self selector:@selector(execute) object:nil]; [queue addOperation:operation]; [operation release]; } Which triggers this: -(void)execute { [[CCSpriteFrameCache sharedSpriteFrameCache]addSpriteFramesWithFile:@"MyTexture.plist"]; loaded = YES; // This tells me whenever loading is done. } However, when I create a sprite and try to use the texture MyTexture.png, the sprite is a blank canvas. Why is that?

• IPhone SDK - Vibration triggered by Thread

  - by Steblo

  Hi, I'm currently working on an IPhone App that should make the phone vibrate if a special event occurs. The checks to trigger the alert is done in a thread. Unfortunately the phone won't vibrate if I call AudioServicesPlaySystemSound(kSystemSoundID_Vibrate); from inside the thread. (It works fine if I call this in my "viewDidAppear" method). I even tried to do a callback from inside the thead like this: inside Thread: [self performSelectorOnMainThread:@selector(doAlarm) withObject:nil waitUntilDone:true]; -(void)doAlarm { AudioServicesPlaySystemSound(kSystemSoundID_Vibrate); } which has the same result: No vibration on the phone. How do I make the phone vibrate from inside a thread ?? Thanks in advance

• Core Data NSFetchedResultsController sorting in certain sequence

  - by Moze

  I'm writing iphone app that has UITableView and uses Core Data. Data in UITableView is shown using NSFetchedResultsController. I use NSPredicate operator "IN" to fetch only needed entries. NSArray *filterArray = [NSArray arrayWithObjects:@"789", @"963", @"445", @"198", nil]; NSPredicate *predicate = [NSPredicate predicateWithFormat:@"id IN %@", filterArray]; Now the problem is that I need to show entries in same sequence they are in filterArray. How can I do it? How I can create NSSortDescriptor that would sort all entries in that way? I tried without sort descriptor, but I get error that NSFetchedResultsController needs sortDescriptor to be set.

• iPhone: How do I override the back button in a Navigation Controller?

  - by Angelo Stracquatanio

  Hello, In my app I have a basic Navigation Controller. For all of my views, except one, the controller works as it should. However, for one view in particular, I would like the 'back' button to not go back to the previous view, but to go to one I set. In particular it is going to go back 2 views and skip over one. After doing some research I found that I can intercept the view when it disappears, so I tried to put in code to have it navigate to the page I would like: - (void)viewWillDisappear:(BOOL)animated { [super viewWillDisappear:animated]; //i set a flag to know that the back button was pressed if (viewPushed) { viewPushed = NO; } else { // Here, you know that back button was pressed mainMenu *mainViewController = [[mainMenu alloc] initWithNibName:@"mainMenu" bundle:nil]; [self.navigationController pushViewController:mainViewController animated:YES]; [mainViewController release]; } } That didn't work, so does anyone have any ideas? Thanks!!

• Textfield being dequeued before textFieldDidEndEditing is called?

  - by Tony

  I am using a uitableview with a bunch of dynamically created custom cells each with a label and textfield similar to the settings app on the phone. Problem occurs when i have a lot of textfields say 20, the user selects the first textfield, changes its value then scrolls to the end of the table and selects the last textfield to edit. I get a EXEC_BAD_ACCESS in the textFieldDidEndEditing method because i think the textfield value is nil?? I think this might be happending because the 1st textfield that was being edited is being dequeued when the table is scrolled. Everything works fine if you select textfields that are next to each other. Any ideas how to fix this?

• UITableView: Need a liveUpdate (Huge amount of cells)

  - by antihero

  Hey all, I have a UITableView which shows some information. The informations are from a XMLFile. The Xmlfile is pretty big, about 500 entries. I don't want that the user has to wait until the parsing has finished, i want to add cell by cell to the TableView. Here's my code: -(void) onFinishedPartDownload:(id)item { if(odvTableViewDelegateController.odvs == nil) odvTableViewDelegateController.odvs = [NSMutableArray new]; if([odvTableViewDelegateController.odvs count]==0) { genericDelegate.tableView.delegate = odvTableViewDelegateController; genericDelegate.tableView.dataSource = odvTableViewDelegateController; } [odvTableViewDelegateController.odvs addObject:item]; [genericDelegate.tableView reloadData]; } This method is called everytime an item has parsed, but it reloads the tableView all at once at the end. I don't have my expected liveUpdate which i'm searching for. The intervall the method is called is about 0.001 to 0.0025 seconds. Any ideas to fix that? Sebastian

• Repeating animations using the Stop Selector

  - by Tiago

  I'm trying to repeat an animation until a certain condition is met. Something like this: - (void) animateUpdate { if (inUpdate) { [UIView beginAnimations:nil context:NULL]; [UIView setAnimationDuration:2.0]; [UIView setAnimationDelegate: self]; [UIView setAnimationDidStopSelector: @selector(animateUpdate)]; button.transform = CGAffineTransformMakeRotation( M_PI ); [UIView commitAnimations]; } } This will run the first time, but it won't repeat. The selector will just be called until the application crashes. How should I do this? Thanks.

• Hash default value not being used

  - by ba

  Today I tried the following snippets of code and I don't understand why I get different results between them. As far as I can understand they are the same. One uses the default value off Hash and the other snippet creates an empty array for the key before it'll be accessed. Anyone who understands what's going on? :) # Hash default if the key doesn't have a value set is an empty Array a = Hash.new([]) a[:key] << 2 # => [2] p a # => {} nil p a[:key] # => [2] # Explicitly add an array for all nodes before creating b = Hash.new b[:key] ||= [] b[:key] << 2 # => [2] p b # => {:key=>[2]}
