  • I would like to flip my app's splash screen - how can I mimic the flipside controller's animation?

    - by Andy
    I've finally gotten a working "alpha" version of my first app installed and (mostly) working on my iPhone 3G. So excited I came into the house and danced a little jig while my wife rolled her eyes at me. Don't care - totally stoked that I figured it out on my own (with lots of help here - thanks again, guys). I've never really dabbled with or cared about animation; I'm more into utility-type apps. However, I've decided that I'd like to animate my app's opening image / default.png / splash screen similar to the flipside view controller animation - where the image spins from a view on the front to a different view on the back. I've found code for animating between views using the flipside animation, but how would I go about animating from a static *.png image to my navigation-based table view? I'm just not even sure where to start with this one - literally the first time I've ever even searched for anything graphics-related in the documentation. Any help will be appreciated. As usual, thanks in advance!

  • Memory Management iOS dev app doesn't work after a few detail items

    - by user1434846
    I am working on a project with a tableView controller and the detail views contains CMMotionManager.When i open 5 or 6 detailViews all goes well,but after a while the app goes slow and finally crashes.On instruments the only leak is on main.m , also i must say that I'm using ARC and i can't dealloc or realese the instances. Here is the code: First the table view: - (void)viewDidLoad { [super viewDidLoad]; // Do any additional setup after loading the view, typically from a nib. self.title = @"Movement";//Master View Controller title bar UIImage *image = [UIImage imageNamed:@"jg_navibar.png"]; [self.navigationController.navigationBar setBackgroundImage:image forBarMetrics:UIBarMetricsDefault]; //Init the array with data bodypartsMutableArray = [NSMutableArray arrayWithCapacity:26]; BodypartData *part1 = [[BodypartData alloc] init]; part1.bodypartname = @"Shoulder"; part1.movementname = @"Flexion"; part1.fullimageStartingPosition=[UIImage imageNamed:@"2_shoulder_flexion_end_position.jpg"]; part1.fullimageEndedPosition=[UIImage imageNamed:@"2_shoulder_flexion_end_position.jpg"]; part1.thumbimage=[UIImage imageNamed:@"1_shoulder_flexion_landmarks_thumb.jpg"]; [bodypartsMutableArray addObject:part1]; ......... } then the cell: - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:@"MyBasicCell"]; BodypartData *part = [self.bodypartsMutableArray objectAtIndex:indexPath.row]; cell.textLabel.text =[NSString stringWithFormat:part.movementname]; cell.detailTextLabel.text =[NSString stringWithFormat:part.bodypartname]; cell.imageView.image =part.thumbimage; return cell; } and the the detailViewdid load: - (void)viewDidLoad { [super viewDidLoad]; // Do any additional setup after loading the view, typically from a nib. // Init motionManager object and set the Update Interval _motionManager = [[CMMotionManager alloc]init]; _motionManager.deviceMotionUpdateInterval=1/60; //60 Hz [_motionManager startGyroUpdates]; if (_motionManager.gyroAvailable) { _motionManager.gyroUpdateInterval = 1.0/60.0; [_motionManager startDeviceMotionUpdatesToQueue:[NSOperationQueue currentQueue] withHandler: ^(CMDeviceMotion *motion, NSError *error) { CMAttitude *attitude = motion.attitude; //Calculation with rotationMatrix m11 = [NSString stringWithFormat:@"%.02f", attitude.rotationMatrix.m11]; m12 = [NSString stringWithFormat:@"%.02f", attitude.rotationMatrix.m12]; m13 = [NSString stringWithFormat:@"%.02f", attitude.rotationMatrix.m13]; ......... }

  • AlarmManager Calling Function in Same Class

    - by jsc123
    I am trying to give a LocationClient a two-minute period to connect before calling getLastLocation on it. Initially I implemented this with a Timer (and TimerTask), but because Timers do not work in sleepmode, I would like to translate it to an AlarmManager. However, I am a bit confused as to how to do this, considering an AlarmManager calls another class, whereas I want to remain in the same class and simply delay for a two-minute period. This is how it looks with a Timer. Timer theTimer = new Timer(); theTimer.schedule(new TimerTask() { @Override public void run() { if(checkIfGooglePlay() && checkTime()) { getPostLocation(); stopSelf(); mLocationClient.disconnect(); } } }, TWO_MINUTES);

  • What exactly is the Nullify delete rule doing?

    - by dontWatchMyProfile
    Does that mean that if I delete an managed object which has references (relationship) to some others, the relationships are removed to those others? Example: objectA references objectB and objectC. objectA gets deleted, it's relationship to objectB and objectC is set to the Nullify rule. What happens in detail?

  • Editable CATextLayer?

    - by Ron
    I have several CATextLayers. When I doubleclick one of them, I want to be able to edit it's string. Think of text as it's handled in Keynote or many other apps. Any ideas? I thought of putting an editable textfield right in front of the layer and then dismiss it on enter, but I didn't get far. :-( I target Mac OS X 10.5 with Objective-C 2.0 and Garbage Collection. Any help or pointers would be greatly appreciated. Thanks in advance!!

  • Mirroring a portion of the screen to an external display (in OSX)

    - by Adam
    I would like to write a program that can mirror a portion of the main display into a new window. Ideally this new window could then be displayed on an external monitor. I have seen this uiltity for a flightsim that does this on a pc (a multifunction display extractor). MFDex http://trac2.assembla.com/lightnings..._x86_Setup.msi I have looked at screen magnifiers or vnc clients for ideas but I think I need to write something from scratch. I have tried to do some reading on osx programing but where do I start in terms of gaining access to the display? I somehow need to extract the graphics from a particular program. Is it best to go near the final output stage (the individual pixels sent to the display) or somewhere nearer the window management stage. Any ideas or pointers would be much appreciated. I just need somewhere to start from. Regards,

  • iPhone: no way to draw on screen outside drawRect?

    - by Seva Alekseyev
    Is there a way to draw on the iPhone screen (on a UIView in a UIWindow) outside of that view's drawRect() method? If so, how do I obtain the graphics context? The graphics guide mentions class NSGraphicsContext, but the relevant chapter seems like a blind copy/paste from Mac OS X docs, and there's no such class in iPhone SDK.

  • how to dynamically recolor a CGGradientRef

    - by saintmac
    I have three CGGradientRef's that I need to be able to dynamically recolor. When I Initialise the CGGradientRef's the first time I get the expected result, but every time I attempt to change the colors nothing happens. Why? gradient is an instance variable ins a subclass of CALayer: @interface GradientLayer : CALayer { CGGradientRef gradient; //other stuff } @end Code: if (gradient != NULL) { CGGradientRelease(gradient); gradient = NULL; } RGBA color[360]; //set up array CGColorSpaceRef rgb = CGColorSpaceCreateDeviceRGB(); gradient = CGGradientCreateWithColorComponents ( rgb, color, NULL, sizeof (color) / sizeof (color[0]) ); CGColorSpaceRelease(rgb); [self setNeedsDisplay];

  • Why are my lines getting thicker and thicker?

    - by mystify
    I try to draw some lines with different colors. This code tries to draw two rectangles with 1px thin lines. However, the second rectangle is drawn with 2px width lines, while the first one is drawn with 1px width. - (void)addLineFrom:(CGPoint)p1 to:(CGPoint)p2 context:(CGContextRef)context { // set the current point CGContextMoveToPoint(context, p1.x, p1.y); // add a line from the current point to the wanted point CGContextAddLineToPoint(context, p2.x, p2.y); } - (void)drawRect:(CGRect)rect { CGContextRef context = UIGraphicsGetCurrentContext(); CGPoint from, to; // ----- draw outer black frame (left, bottom, right) ----- CGContextBeginPath(context); // set the color CGFloat lineColor[4] = {26.0f * colorFactor, 26.0f * colorFactor, 26.0f * colorFactor, 1.0f}; CGContextSetStrokeColor(context, lineColor); // left from = CGPointZero; to = CGPointMake(0.0f, rect.size.height); [self addLineFrom:from to:to context:context]; // bottom from = to; to = CGPointMake(rect.size.width, rect.size.height); [self addLineFrom:from to:to context:context]; // right from = to; to = CGPointMake(rect.size.width, 0.0f); [self addLineFrom:from to:to context:context]; CGContextStrokePath(context); CGContextClosePath(context); // ----- draw the middle light gray frame (left, bottom, right) ----- CGContextSetLineWidth(context, 1.0f); CGContextBeginPath(context); // set the color CGFloat lineColor2[4] = {94.0f * colorFactor, 94.0f * colorFactor, 95.0f * colorFactor, 1.0f}; CGContextSetStrokeColor(context, lineColor2); // left from = CGPointMake(200.0f, 1.0f); to = CGPointMake(200.0f, rect.size.height - 2.0f); [self addLineFrom:from to:to context:context]; // bottom from = to; to = CGPointMake(rect.size.width - 2.0f, rect.size.height - 2.0f); [self addLineFrom:from to:to context:context]; // right from = to; to = CGPointMake(rect.size.width - 2.0f, 1.0f); [self addLineFrom:from to:to context:context]; // top from = to; to = CGPointMake(1.0f, 1.0f); [self addLineFrom:from to:to context:context]; CGContextStrokePath(context); }

  • Endless saving of CoreData Context

    - by Robert
    Sometimes I noticed that a 'save:' operation an a ManagedObjectContext never returns and consumes 100% CPU. I'm using an SQL Store in a GarbageCollected environment (Mac OS X 10.6.3). The disk activity shows about 700 KB/s writing. While having a look at the folder that contains the sqlite database file the "-journal" file appears and disappears, appears and disappears, ... This is part of the call graph from the process analysis: 2203 -[NSManagedObjectContext save:] 1899 -[NSPersistentStoreCoordinator(_NSInternalMethods) executeRequest:withContext:] 1836 -[NSSQLCore executeRequest:withContext:] 1836 -[NSSQLCore saveChanges:] 1479 -[NSSQLCore performChanges] ... 335 -[NSSQLCore recordChangesInContext:] ... 20 -[NSSQLCore rollbackChanges] ... 2 -[NSSQLCore prepareForSave:] ... 62 -[NSPersistentStoreCoordinator(_NSInternalMethods) _checkRequestForStore:originalRequest:andOptimisticLocking:] ... 1 -[NSPersistentStore(_NSInternalMethods) _preflightCrossCheck] ... 184 -[NSMergePolicy resolveConflicts:] ... 120 -[NSManagedObjectContext(_NSInternalChangeProcessing) _prepareForPushChanges:] ... Everything a happening in the main GUI thread. Any ideas what I can to do to resolve the problem?

  • CALayer not obeying object ownership rules?

    - by eaigner
    I have a custom CALayer - UIProgressLayer - for simulating a progress bar. There is a dispatched GC timer involved to animate its intermediate state. So thats the layer I'm talking about here, although i don't think the problem is restricted to this particular subclass because a CALayer with only the -release and -dealloc overridden produces the same outcome. The problem is when i send this layer, for instance, a theLayer.opacity = 0.5f a -release message is sent to the layer, thus deallocating my layer. Why is this happening? Has it something to do with how the whole CA system works? But it still has to obey the object ownership rules right? I was thinking maybe it creates a copy of that layer for the fading, but that's not the case.

  • Is there any seriously good reason why a view can not completely manage itself?

    - by mystify
    Example: I have an warning triangle icon, which is a UIImageView subclass. That warning is blended in with an animation, pulses for 3 seconds and then fades out. it always has a parent view! it's always only used this way: alloc, init, add as subview, kick off animation, when done:remove from superview So I want this: [WarningIcon warningAtPosition:CGPointMake(50.0f, 100.0f) parentView:self]; BANG! That's it. Call and forget. The view adds itself as subview to the parent, then does it's animations. And when done, it cuts itself off from the branch with [self removeFromSupeview];. Now some nerd a year ago told me: "Never cut yourself off from your own branch". In other words: A view should never ever remove itself from superview if it's no more referenced anywhere. I want to get it, really. WHY? Think about this: The hard way, I would do actually the exact same thing. Create an instance and hang me in as delegate, kick off the animation, and when the warning icon is done animating, it calls me back "hey man i'm done, get rid of me!" - so my delegate method is called with an pointer to that instance, and I do the exact same thing: [thatWarningIcon removeFromSuperview]; - BANG. Now I'd really love to know why this sucks. Life would be so easy.

  • Dealloc'd Predicate crashing iPhone App!

    - by DVG
    To preface, this is a follow up to an inquiry made a few days ago: http://stackoverflow.com/questions/2981803/iphone-app-crashes-when-merging-managed-object-contexts Short Version: EXC_BAD_ACCESS is crashing my app, and zombie-mode revealed the culprit to be my predicate embedded within the fetch request embedded in my Fetched Results Controller. How does an object within an object get released without an explicit command to do so? Long Version: Application Structure Platforms View Controller - Games View Controller (Predicated upon platform selection) - Add Game View Controller When a row gets clicked on the Platforms view, it sets an instance variable in Games View for that platform, then the Games Fetched Results Controller builds a fetch request in the normal way: - (NSFetchedResultsController *)fetchedResultsController{ if (fetchedResultsController != nil) { return fetchedResultsController; } //build the fetch request for Games NSFetchRequest *request = [[NSFetchRequest alloc] init]; NSEntityDescription *entity = [NSEntityDescription entityForName:@"Game" inManagedObjectContext:context]; [request setEntity:entity]; //predicate NSPredicate *predicate = [NSPredicate predicateWithFormat:@"platform == %@", selectedPlatform]; [request setPredicate:predicate]; //sort based on name NSSortDescriptor *sortDescriptor = [[NSSortDescriptor alloc] initWithKey:@"name" ascending:YES]; NSArray *sortDescriptors = [[NSArray alloc] initWithObjects:sortDescriptor, nil]; [request setSortDescriptors:sortDescriptors]; //fetch and build fetched results controller NSFetchedResultsController *aFetchedResultsController = [[NSFetchedResultsController alloc] initWithFetchRequest:request managedObjectContext:context sectionNameKeyPath:nil cacheName:@"Root"]; aFetchedResultsController.delegate = self; self.fetchedResultsController = aFetchedResultsController; [sortDescriptor release]; [sortDescriptors release]; [predicate release]; [request release]; [aFetchedResultsController release]; return fetchedResultsController; } At the end of this method, the fetchedResultsController's _fetch_request - _predicate member is set to an NSComparisonPredicate object. All is well in the world. By the time - (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section gets called, the _predicate is now a Zombie, which will eventually crash the application when the table attempts to update itself. I'm more or less flummoxed. I'm not releasing the fetched results controller or any of it's parts, and the only part getting dealloc'd is the predicate. Any ideas?

  • managedObjectContext question...

    - by treasure
    Hello, I have an app which is a UITabBarController, I have defined two subviews Both tabs have their Class attribute in the Identity Inspector set to UINavigationController. Now i have managed to get this far with my coding after VERY LONG trials. - (void)viewDidLoad { [super viewDidLoad]; myAppDelegate *appDelegate = (myAppDelegate *)[[UIApplication sharedApplication] delegate]; self.managedObjectContext = appDelegate.managedObjectContext; { NSError *error = nil; NSFetchRequest *fetchRequest = [[NSFetchRequest alloc] init]; [fetchRequest setEntity:[NSEntityDescription entityForName:@"User" inManagedObjectContext:self.managedObjectContext]]; NSArray *fetchedItems = [self.managedObjectContext executeFetchRequest:fetchRequest error:&error]; NSEntityDescription *entityDesc = [NSEntityDescription entityForName:@"User" inManagedObjectContext:self.managedObjectContext]; // replace the old data with new. this DOESNT WORK if (fetchedItems.count > 0) { Usr *newUsr; for (newUsr in fetchedItems) { if ([newUsr.name isEqualToString:@"Line One"]) { newUsr.uName = @"Line One (new)"; } } } //add a new default data. THIS ADDS DATA TO MY TABLEVIEW BUT IT DOESNT SAVE THEM TO THE SQLITE User *addedDefaultdata = nil; addedDefaultdata = [[User alloc] initWithEntity:entityDesc insertIntoManagedObjectContext:self.managedObjectContext]; addedDefaultdata.name = @"Added new 1"; [addedDefaultdata release]; } NSError *error = nil; if (![[self fetchedResultsController] performFetch:&error]) { NSLog(@"Unresolved error %@, %@", error, [error userInfo]); abort(); } } and my appdelegate looks like this: - (void)applicationDidFinishLaunching:(UIApplication *)application { [application setStatusBarStyle:UIStatusBarStyleBlackOpaque]; [window addSubview:navigationController.view]; [window makeKeyAndVisible]; } now I cannot quire the "User" at all! although i get no errors or warnings! Any suggestions would be much appreciated! Thanks

  • Extending a view to the left side, animated

    - by Heinrich
    Hi, I have a view that I want to extend on the left side using an animation. All borders but the left one should remain the same, so the x position and the width of the view are changing. I use this code: [UIView beginAnimations:nil context:nil]; [UIView setAnimationDuration:5.0]; self.frame = CGRectMake(self.frame.origin.x-100, self.frame.origin.y, self.frame.size.width+100, self.frame.size.height); [UIView commitAnimations]; If I run this code, the width of the view is set to the new value immediately and then the view is moved to the new x point, but why? How can I change this behaviour? Thanks for your ideas!

  • How to find an audio file's length (in seconds)

    - by mIL3S
    Hi all! (Objective C) Just using simple AudioServicesPlaySystemSoundID and its counterparts, but I can't find in the documentation if there is already a way to find the length of an audio file. I know there is AudioServicesGetPropertyInfo, but that seems to return a byte-buffer - do audio files embed their length in themselves and I can just extract it with this? Or is there perhaps a formula based on bit-rate * fileSize to convert to length-of-time? mIL3S www.milkdrinkingcow.com
