  • inserting new relationship data in core-data

    - by michael
    My app will allow users to create a personalised list of events from a large list of events. I have a table view which simply displays these events, tapping on one of them takes the user to the event details view, which has a button "add to my events". In this detailed view I own the original event object, retrieved via an NSFetchedResultsController and passed to the detailed view (via a table cell, the same as the core data recipes sample). I have no trouble retrieving/displaying information from this "event". I am then trying to add it to the list of MyEvents represented by a one to many (inverse) relationship: This code: NSManagedObjectContext *context = [event managedObjectContext]; MyEvents *myEvents = (MyEvents *)[NSEntityDescription insertNewObjectForEntityForName:@"MyEvents" inManagedObjectContext:context]; [myEvents addEventObject:event];//ERROR And this code (suggested below): //would this add to or overwrite the "list" i am attempting to maintain NSManagedObjectContext *context = [event managedObjectContext]; MyEvents *myEvents = (MyEvents *)[NSEntityDescription insertNewObjectForEntityForName:@"MyEvents" inManagedObjectContext:context]; NSMutableSet *myEvent = [myEvents mutableSetValueForKey:@"event"]; [myEvent addObject:event]; //ERROR Bot produce (at the line indicated by //ERROR): *** -[NSComparisonPredicate evaluateWithObject:]: message sent to deallocated instance Seems I may have missed something fundamental. I cant glean any more information through the use of debugging tools, with my knowledge of them. 1) Is this a valid way to compile and store an editable list like this? 2) Is there a better way? 3) What could possibly be the deallocated instance in error? -- I have now modified the Event entity to have a to-many relationship called "myEvents" which referrers to itself. I can add Events to this fine, and logging the object shows the correct memory addresses appearing for the relationship after a [event addMyEventObject:event];. The same failure happens right after this however. I am still at a loss to understand what is going wrong. This is the backtrace #0 0x01f753a7 in ___forwarding___ () #1 0x01f516c2 in __forwarding_prep_0___ () #2 0x01c5aa8f in -[NSFetchedResultsController(PrivateMethods) _preprocessUpdatedObjects:insertsInfo:deletesInfo:updatesInfo:sectionsWithDeletes:newSectionNames:treatAsRefreshes:] () #3 0x01c5d63b in -[NSFetchedResultsController(PrivateMethods) _managedObjectContextDidChange:] () #4 0x0002e63a in _nsnote_callback () #5 0x01f40005 in _CFXNotificationPostNotification () #6 0x0002bef0 in -[NSNotificationCenter postNotificationName:object:userInfo:] () #7 0x01bbe17d in -[NSManagedObjectContext(_NSInternalNotificationHandling) _postObjectsDidChangeNotificationWithUserInfo:] () #8 0x01c1d763 in -[NSManagedObjectContext(_NSInternalChangeProcessing) _createAndPostChangeNotification:withDeletions:withUpdates:withRefreshes:] () #9 0x01ba25ea in -[NSManagedObjectContext(_NSInternalChangeProcessing) _processRecentChanges:] () #10 0x01bdfb3a in -[NSManagedObjectContext processPendingChanges] () #11 0x01bd0957 in _performRunLoopAction () #12 0x01f4d252 in __CFRunLoopDoObservers () #13 0x01f4c65f in CFRunLoopRunSpecific () #14 0x01f4bc48 in CFRunLoopRunInMode () #15 0x0273878d in GSEventRunModal () #16 0x02738852 in GSEventRun () #17 0x002ba003 in UIApplicationMain () solution I managed to get to the bottom of this. I was fetching the event in question using a NSFetchedResultsController with a NSPredicate which I was releasing after I had the results. Retrieving values from the entities returned was no problem, but when I tried to update any of them it gave the error above. It should not have been released. oustanding part of my question What is a good way to create this sub list from a list of existing items in terms of a core data model. I don't believe its any of the ways I tried here. I need to show/edit it in another table view. Perhaps there is a better way than a boolean property on each event entity? The relationship idea above doesn't seem to work here (even though I can now create it). Cheers.

  • Why didn't Apple initially implement copy and paste in the iPhone?

    - by Howiecamp
    Why didn't Apple implement copy and paste prior to iPhone OS 3.0? The answers I don't think are correct (but I could certainly be wrong) are: They couldn't figure out how to do it and provide a good user experience Some crazy multi-tasking or battery limitation iPhone users didn't want or need it (this was Microsoft's argument and is totally specious) Thoughts?

  • Left with extra UITableViewCell after re-ordering

    - by Mark F
    After going into Edit mode, moving a cell, and leaving edit mode, i am left with one extra cell sitting on top of its duplicate cell while still in edit mode. The problem has to be somewhere in here: - (void)tableView:(UITableView *)tableView moveRowAtIndexPath:(NSIndexPath *)sourceIndexPath toIndexPath:(NSIndexPath *)destinationIndexPath { NSMutableArray *array = [[fetchedResultsController fetchedObjects] mutableCopy]; id objectToMove = [[array objectAtIndex:sourceIndexPath.row] retain]; [array removeObjectAtIndex:sourceIndexPath.row]; [array insertObject:objectToMove atIndex:destinationIndexPath.row]; [objectToMove release]; for (int i=0; i<[array count]; i++) { [(NSManagedObject *)[array objectAtIndex:i] setValue:[NSNumber numberWithInt:i] forKey:@"userOrder"]; } [array release]; } Any guidance greatly appreciated!

  • Extended SurfaceView onDraw never called

    - by Gab Royer
    Hi, I'm trying to modify the SurfaceView I use for doing a camera preview in order to display an overlaying square. However, the onDraw method of the extended SurfaceView is never called. Here is the source : public class CameraPreviewView extends SurfaceView { protected final Paint rectanglePaint = new Paint(); public CameraPreviewView(Context context, AttributeSet attrs) { super(context, attrs); rectanglePaint.setARGB(255, 200, 0, 0); rectanglePaint.setStyle(Paint.Style.FILL); rectanglePaint.setStrokeWidth(2); } @Override protected void onDraw(Canvas canvas){ canvas.drawRect(new Rect(10,10,200,200), rectanglePaint); Log.w(this.getClass().getName(), "On Draw Called"); } } public class CameraPreview extends Activity implements SurfaceHolder.Callback{ private SurfaceHolder holder; private Camera camera; @Override protected void onCreate(Bundle savedInstanceState){ super.onCreate(savedInstanceState); // We remove the status bar, title bar and make the application fullscreen requestWindowFeature(Window.FEATURE_NO_TITLE); getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN); // We set the content view to be the layout we made setContentView(R.layout.camera_preview); // We register the activity to handle the callbacks of the SurfaceView CameraPreviewView surfaceView = (CameraPreviewView) findViewById(R.id.camera_surface); holder = surfaceView.getHolder(); holder.addCallback(this); holder.setType(SurfaceHolder.SURFACE_TYPE_PUSH_BUFFERS); } public void surfaceChanged(SurfaceHolder holder, int format, int width, int height) { Camera.Parameters params = camera.getParameters(); params.setPreviewSize(width, height); camera.setParameters(params); try { camera.setPreviewDisplay(holder); } catch (IOException e) { e.printStackTrace(); } camera.startPreview(); } public void surfaceCreated(SurfaceHolder holder) { camera = Camera.open(); } public void surfaceDestroyed(SurfaceHolder holder) { camera.stopPreview(); camera.release(); } }

  • Prevent an Activity from being killed by the OS while starting a child activity

    - by Martin Marinov
    I have a main activity which calls a child one via Intent I = new Intent(this, Child.class); startActivityForResult(I, 0); But as soon as Child becomes visible the main activity gets its onStop and immediately after that onDestroy method triggered. And as soon as I call finish() within the Child activity or press the back button, the Child activity closes and the home screen shows (instead of the main activity). How can I prevent the main activity from being destroyed? :\

  • How to prevent modal view controllers flashing when changing

    - by KP Overflow
    I have three view controllers, let's call them A, B and C. When a button is pressed on view A, view B is shown using presentModalViewController:animated: When the finish button is pressed on screen B, it dismisses itself. View A is notified whereupon it immediately shows view C, again using presentModalViewController:animated: The problem is that view A's content is momentarily flashed on the screen between view B closing and view C opening. I can get around this by making view A blank and moving it's current content to a new view, D. (For various reasons, I don't want view B to own view C, that's why it's not opening it) Am I over-complicating this? I'm sure there is a smarter way to go? ThanksT

  • How to change font size in a pickerview?

    - by user183804
    I'm fairly new to iPhone programming and am trying to implement a double-component PickerView. At this point the picker works fine in terms of taking user input, created with Interface Builder. However, I need to change the font size to accommodate the text length in each column. I very much would appreciate any link to a straightforward method to creating a multi-component picker with an adjustable font size. Seems like it is not possible if Interface Builder is used to create the picker. So far I have not found any code links that address this issue in detail. Thanks in advance.

  • How to get orientation of android from gyrsocope sensor events ?

    - by Pritam
    I am using android 2.3 on Nexus S and want to get orientation from gyroscope sensor events. As gyro gives angular velocity how to use this for getting device orientation ? Also is there any way we can get pure linear accelerations on phone's axis, without gravity vector. I expected this from Linear acceleration sensor event but just found a post and referred android source as well for Sensor which currently uses only accelerometer. So what's the best way to combine the readings from both hardware to get pure accelerations without gravity inclusions ? Thanks.
