  • In App Purchase Resources Security.

    - by jAmi
    Hi I am setting up in app purchase where user can buy different Sounds. Once bought, he can play those sounds in the App. The Sound files are all present in my Resources Folder and I just keep a record(in a plist) of the files that have been purchased. No If I right click on the IAP file and see its content I can see the Resources, hence any one can have those sounds without actually buying them. Is there a protected Bundle or something?

  • How to increment a value using a C-Preprocessor in Objective-C?

    - by mystify
    Example: I try to do this: static NSInteger stepNum = 1; #define METHODNAME(i) -(void)step##i #define STEP METHODNAME(stepNum++) @implementation Test STEP { // do stuff... [self nextFrame:@selector(step2) afterDelay:1]; } STEP { // do stuff... [self nextFrame:@selector(step3) afterDelay:1]; } STEP { // do stuff... [self nextFrame:@selector(step4) afterDelay:1]; } // ... When building, Xcode complains that it can't increment stepNum. This seems logical to me, because at this time the code is not "alive" and this pre-processing substitution stuff happens before actually compiling the source code. Is there another way I could have an variable be incremented on every usage of STEP macro, the easy way?

  • CoreData could not fulfill a fault when adding new attribute

    - by cagreen
    I am receiving a "CoreData could not fulfill a fault for ..." error message when trying to access a new attribute in a new data model. If I work with new data I'm ok, but when I attempt to read existing data I get the error. Do I need to handle the entity differently myself if the attribute isn't in my original data? I was under the impression that Core Data could handle this for me. My new attribute is marked as optional with a default value. I have created a new .xcdatamodel (and set it to be the current version) and updated my NSPersistentStoreCoordinator initialization to take advantage of the lightweight migration as follows: NSDictionary *options = [NSDictionary dictionaryWithObjectsAndKeys: [NSNumber numberWithBool:YES], NSMigratePersistentStoresAutomaticallyOption, [NSNumber numberWithBool:YES], NSInferMappingModelAutomaticallyOption, nil]; NSError *error = nil; persistentStoreCoordinator = [[NSPersistentStoreCoordinator alloc] initWithManagedObjectModel:[self managedObjectModel]]; if (![persistentStoreCoordinator addPersistentStoreWithType:NSSQLiteStoreType configuration:nil URL:storeUrl options:options error:&error]) { NSLog(@"Unresolved error %@, %@", error, [error userInfo]); abort(); } Any help is appreciated.

  • Events do not propagate from a child element?

    - by Legend
    I was playing around with the Swipe jQuery plugin on my iPod Touch and Android devices. The following works: <html> <head> <script type="text/javascript" src="lib/jquery/jquery-1.3.2.js"></script> <script type="text/javascript" src="lib/plugins/jquery.swipe.js"></script> <script type="text/javascript"> $(function() { $('body').swipe({ swipeLeft: function() { $('#container1').append("Swiped Left!"); }, swipeRight: function() { $('#container2').append("Swiped Right!");} }); }); </script> <style type="text/javascript"> body {width: 300px; height: 300px; background: #000;} </style> </head> <body> <div id="container1"> This is container one </div> <div id="container2"> This is container two </div> </body> </html> But if I have something like this: <html> <head> <script type="text/javascript" src="lib/jquery/jquery-1.3.2.js"></script> <script type="text/javascript" src="lib/plugins/jquery.swipe.js"></script> <script type="text/javascript"> $(function() { $('#wrapper').swipe({ swipeLeft: function() { $('#container1').append("Swiped Left!"); }, swipeRight: function() { $('#container2').append("Swiped Right!");} }); }); </script> <style type="text/javascript"> body {width: 300px; height: 300px; background: #000;} </style> </head> <body> <div id="wrapper"> <div id="container1"> This is container one </div> <div id="container2"> This is container two </div> </div> </body> </html> Notice the "wrapper" div around the containers. Now, when I swipe on the div element, I was expecting it to actually trigger the event. This works in iPod touch as expected but does not work on my Android device unless I randomly start swiping everywhere until I happen to swipe on that small wrapper div element itself. I am not sure how to explain this but hink of it as sending events to the wrapper div itself. Both use the WebKit engine. Can someone tell me if I am doing something wrong?

  • iOS: How to access the `UIKeyboard`?

    - by MattDiPasquale
    I want to get a pointer reference to UIKeyboard *keyboard to the keyboard on screen so that I can add a transparent subview to it, covering it completely, to achieve the effect of disabling the UIKeyboard without hiding it. In doing this, can I assume that there's only one UIKeyboard on the screen at a time? I.e., is it a singleton? Where's the method [UIKeyboard sharedInstance]. Brownie points if you implement that method via a category. Or, even more brownie points if you convince me why it's a bad idea to assume only one keyboard and give me a better solution.

  • How can I display the camera view in the main window in real time?

    - by Mongrel Warfare
    I'm trying to make an augmented reality application with a waypoint structure, like Yelp, and I'm wondering how to set up my main view so that it displays the camera view on the whole screen. I've heard of using the UIImagePickerController Class, but I'm unsure how to manipulate the code so that it doesn't actually take a picture, but just stays in the view mode. Any help would be appreciated, thanks!

  • How to define colors in XCodes' Interface Builder?

    - by favo
    Hi, I would like to copy colors between elements in the interface builder or define them using RGB values. I.e. copy the background color of a button to another button without duplicating the button. Or: Enter an exact RGB code using the interface builder. Currently I can do this only programmatically but the interface builder is meant to design the GUI, so there must be such possibilities. Thank you all in advance for your answers.

  • How to animate a UIButton selected background Image

    - by Thomas Joos
    hi all, I have a class defining a custom UIButton. I configurate a normal and selected state like this: //custom image UIImage *image = [UIImage imageNamed:@"customIconCreationBG.png"]; UIImage *stretchImage = [image stretchableImageWithLeftCapWidth:0.0 topCapHeight:0.0]; [self setBackgroundImage:stretchImage forState:UIControlStateNormal]; UIImage *imageSelected = [UIImage imageNamed:@"customIconCreationBG_selected.png"]; UIImage *stretchImageSelected = [imageSelected stretchableImageWithLeftCapWidth:0.0 topCapHeight:0.0]; [self setBackgroundImage:stretchImageSelected forState:UIControlStateSelected]; In another class I'm filling an array with custom buttons and i'm adding a button pressed method. It sets the selected state to TRUE -(void)buttnPressed:(id)sender { NSLog(@"button pressed"); [[NSNotificationCenter defaultCenter] postNotificationName:@"unselectBGIcons" object:self]; HorizontalListIcon *pressedIcon = ((HorizontalListIcon *)sender); [pressedIcon setSelected:TRUE]; } The button switches to another background, which is great. Is there a way to animate this change ( fading in? ) because it's a bit hard now. Greets

  • Effect of 'myObj = [[[[MyClass alloc] init] autorelease] retain];'?

    - by filipe
    I've just downloaded the Facebook iOS SDK and I noticed that in the sample code that comes with the SDK whenever it creates an instance of the Facebook class it does it like this: _facebook = [[[[Facebook alloc] init] autorelease] retain]; where _facebook is a member variable of the calling object (i.e. not a local variable). Can anyone explain exactly what's the point of autoreleasing and then retaining it?

  • UIImageView is clipping a pixel of the bottom of my UIImage...?

    - by akaii
    I'm not sure what might be causing this, but UIImageView occasionally clips off about a pixel or 2 from the bottom of some square/rectangular UIImages I'm using as subviews for UITableViewCells. These UIImageViews are well within the borders of the cell, so it shouldn't be due to cliptobounds. There seems to be no consistency or pattern to which images are being clipped, nor when they're clipped, other than that it only happens to (or is only noticable in) square/rectangular icons, and only ones that are parented to UITableViewCells (or their subclasses). I'm having trouble reproducing the problem consistently, which is why I haven't posted any code this time. Has anyone encountered something similar to this before? I've encountered a similar bug that involved floating point values for origin/size being interpreted weirdly... but that doesn't seem to be the cause of this particular problem. I don't need a specific solution at this point, I'm just making sure I haven't missed any well-known bugs or documented problems that involve UIImageView.

  • Tab Bar disappears below the bottom of the screen

    - by Manu
    Hi, In my application I'm using a Navigation Controller to push one view that loads a Tab Bar Controller and a custom Navigation Bar as well. The problem is that the Tab Bar disappears below the bottom of the screen, and I don't know what's causing the problem. If I load a simple Tab Bar in the next view, it positions itself correctly... but what I need is a Tab Bar Controller, and in that case the Tab Bar disappears below the bottom. I have tried changing the view and size properties of the Tab Bar, but that did not solve the problem. I also realised that the images and text of the tabs don't show (I have set up the "favourites" and "contacts" images and text, and they are big enough and should be visible on the top side of the tab, but they are not). Both tabs work perfectly, by the way. There is an image here. I load the Tab Bar with the following code: - (void)viewDidLoad { [super viewDidLoad]; myTabBarController = [[UITabBarController alloc] init]; SettingsViewController* tab1 = [[SettingsViewController alloc] init]; AboutViewController* tab2 = [[AboutViewController alloc] init]; NSArray* controllers = [NSArray arrayWithObjects:tab1, tab2, nil]; myTabBarController.viewControllers = controllers; [self.view insertSubview:myTabBarController.view belowSubview:myNavigationBar]; } It doesn't matter if I remove the Navigation Bar or not. I have tested using this instead: [self.view addSubview:myTabBarController.view]; ... forgetting about the Navigation Bar, but the Tab Bar still goes under the bottom. I don't know if the problem is in one of my NIB files or in how I load the view (although I do this as I read in the Apple's SDK documentation). Any ideas? Another question would be... do you know how could I change the title of my Navigation Bar when I select the second tab? I imagine I would have to do it in viewDidLoad in AboutViewController.m, would that be correct? Thanks for you time!

  • performSelectorInBackground, notify other viewcontroller when done.

    - by Michiel
    Hi, I have a method used to save an image when the user clicks Save. I use performSelectorInBackground to save the image, the viewcontroller is popped and the previous viewcontroller is shown. I want the table (on the previousUIViewController) to reload its data when the imagesaving is done. How can I do this? The save method is called like this: [self performSelectorInBackground:@selector(saveImage) withObject:nil]; [self.navigationController popViewControllerAnimated:YES];

  • How do I change the UIView programmatically?

    - by user317834
    I have created View A and View B. My window has View A displayed on the screen. I also have a UIButton on View A. I want to switch from View A to View B when I click on the Button. I am not using any UIViewController. Is it possible to switch the views without using controller? I am calling buttonAction method on TOUCHUPINSIDE The problem is that it doesn't do anything when I say [ViewA removeFromSuperView]; What should I do now?

  • iOS: click counter for row in tableview

    - by roger.arliner21
    I am developing and tableView in which in each row I have to display the click counter and row number.Each cell must have an initial click counter value of 0 when application is initialized. Then increment the click counter value within a cell whenever a user clicks on the cell. I have take 26 fixed rows. I have taken tableData.plist file as in the attached image. I am initializing the self.dataArray with the plist . Now I want to do implementation in the didSelectRowAtIndexPath delegate method,if any row is tapped that row's click counter should increment. - (void)viewDidLoad { [super viewDidLoad]; NSString *path = [[NSBundle mainBundle] pathForResource:@"tableData" ofType:@"plist"]; self.dataArray = [NSMutableArray arrayWithContentsOfFile:path];//array initialized with plist } - (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section { return [self.dataArray count]; } - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *kCustomCellID = @"MyCellID"; UILabel *label1 = [[UILabel alloc] initWithFrame:CGRectMake(160.0f, 2.0f, 30.0f, 20.0f)]; UILabel *label2 = [[UILabel alloc] initWithFrame:CGRectMake(160.0f, 24.0f, 30.0f, 30.0f)]; label2.textColor = [UIColor grayColor]; UITableViewCell *cell = (UITableViewCell *)[tableView dequeueReusableCellWithIdentifier:kCustomCellID]; if (cell == nil) { cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:kCustomCellID] autorelease]; cell.selectionStyle = UITableViewCellSelectionStyleNone; } if([self.dataArray count]>indexPath.row) { label1.text = [[self.dataArray objectAtIndex:indexPath.row] objectForKey:@"Lable1"]; label2.text =[[self.dataArray objectAtIndex:indexPath.row] objectForKey:@"Lable2"]; } else { label1.text = @""; label2.text =@""; } [cell.contentView addSubview:label1]; [cell.contentView addSubview:label2]; [label1 release]; [label2 release]; return cell; } #pragma mark - #pragma mark Table view delegate - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { //implementation for row counter incrementer. }

  • Download data in background with iOS4

    - by Sagar
    As per the latest update of Kindle V2.5, it has support of "continue downloading books while the app is in the background on iOS 4 devices". How is it possible to download content in background? As per the iOS multitasking documentation, only audio, voip & location updates are possible in background. And I've also maken sure that NSURLConnection doesn't download new data work while app goes background. Then how's it possible with Kindle app? Edit: I haven't checked Kindle App in iOS4 multitasking enabled device. So if anyone let me (& community) know what exactly Kindle app does to download, that would be very much helpful.

  • If I create a transient property in the model, isn't this managed by core data then?

    - by mystify
    Just to grok this: If I had a transient property, lets say averagePrice, and I mark that as "transient" in the data modeler: This will not be persistet, and no column will be created in SQLite for that? And: If I make my own NSManagedObject subclass with an averagePrice property, does it make any sense to model that property in the xcdatamodel file? Would it make a difference if I would simply create a property in my subclass and not model that in the entity? (I think: yes, it doesn't matter at all ... but not sure)

  • IOS : BAD ACCESS when trying to add a new Entity object

    - by Maverick447
    So i'm using coredata to model my relationships . This is the model in brief Type A can have one or more types of type B Type B has a inverse relationship of being associated with one of type A Type B can have one or more types of type C Type C has a inverse relationship of being associated with one of type B From a UI standpoint , I have a Navigation controller with controllers that successively sets up the first A object (VC-1) , then another viewcontroller (VC-2) creates a B object ( I pass in the A object to this controller) and the B object is added to the A object . Similarly the same thing happens with B and C . The third Viewcontroller (VC3) first creates a C object and assigns it to the passed B Object . Also between these viewcontrollers the managedObjectCOntext is also passed . SO my use case is such that while viewcontroller (VC-3) is the top controller a button action will keep creating multiple objects of type C and add them to the same type B object that was passed . Also as part of this function I save the managedObject context after saving each type C . e.g. code in viewcontroller 3 - (void) SaveNewTypeC { TypeC *newtypeC = (Question*)[NSEntityDescription insertNewObjectForEntityForName:@"TypeC" inManagedObjectContext:managedObjectContext]; [newtypeC setProp1:] ; [newtypeC setProp2:] .. .. **[typeBObject addTypeCInTypeBObject:newtypeC];** [section setTotalCObjectCount:[ NSNumber numberWithInt:typeCIndex++]]; NSError *error = nil; if (![managedObjectContext save:&error]) { // Handle error NSLog(@"Unresolved error %@, %@, %@", error, [error userInfo],[error localizedDescription]); exit(-1); // Fail } [newtypeC release]; } - (IBAction)selectedNewButton:(id)sender { [self SaveNewTypeC]; [self startRepeatingTimer]; } The BAD ACCESS seems to appear when the bold line above executes Relating to some HashValue . Any clues on resolving this would be helpful .

  • UIViewController is popped from view stack and NSURLConnection crashes the application

    - by rickharrison
    I am pushing a UIViewController onto a UINavigationController. This view controller immediately starts a download of an xml feed and then parses it. However, if you hit the back button before it is done downloading, and crashes with EXC_BAD_ACCESS. The line that is crashing it is in parserDidEndDocument and is this line: if (self.delegate && [self.delegate conformsToProtocol:@protocol(ModelDelegate)]) [self.delegate modelDidFinishParsing:self]; I assume it is crashing because it is trying to access self.delegate which is not assigned anymore. How do I get around this? Also, I would release the model object in the modelDidFinishParsing method. How would I release this model if it never reaches this method.

  • Delete NSManageObject at the event tableView:commiteEditingStyle:forRowAtIndexPath:

    - by David.Chu.ca
    I got exception when I tried to delete one NSManageObject at the event of tableView:commiteEditingStyle:forRowAtIndexPath:. Here is the part of my codes: - (void)tableView:(..)tableView commitEditingStyle:(..)editingStyle forRowAtIndexPath:(..)indexPath { if (editingStyle == UITableViewCellEditingStyleDelete) { [managedObjectContext deleteObject: [fetchedResultController objectAtIndexPath:indexPath]]; ... } } The exception was thrown at the line of deleteObject:(method of my local NSManagedObjectContext). This is the exception message: uncaught exception 'NSObjectInaccessibleException', reason: 'The NSManagedObject with ID:0x3d07a30 <x-coredata://0D2CC9CB-042B-496D-B3FE-5F1ED64EAB97/paymentType/p2> has been invalidated.' I tried to get entity object first and then to delete it. The entity looks OK but still the exception was at delete: NSManagedObject *entityToDelete = [fetchedResultsController objectAtIndexPath:indexPath]; [mangedObjectContext deleteObject:entityToDelete]; // Exception again. I am not sure if the entity object retrieved from the fetchedResultsController(NSFetchedResultsController type) cannot be deleted? If so, is there any other way to get the entity object for deleting?
