  • How to play the same Sound multiple times with overlap, using OpenAL or Finch?

    - by mystify
    Finch uses OpenAL. However, when I have an instance of Sound, and say -play, the sound plays. When I call -play multiple times one after another in a fast paced way, every -play makes the current sound playback of that sound stop and restart it. That's not what I want. Would I have to create multiple sources or buffers to get that working? Or would I just instantiate multiple Sounds with the same file?

  • Verifying the purchaser of an App Store application

    - by Keldi
    Is there a way for the developer of an App Store application to tie a sale to an individual user/device ID/Apple account? In other words, a method for the developer to double-check that a specific user has legally purchased the software? I haven't been able to find a reliable answer to this yet. I'm not looking for specific code examples, just some sort of idea as to how possible (or difficult) this is. My intent isn't to penalize piracy; it's to be able to provide additional benefits to paid customers. As such, I'm not looking for a way to identify a cracked or pirated version, which I gather has already been solved. Thanks in advance for any help you can provide!

  • To store images from UIGetScreenImage() in NSMutable Array

    - by sujyanarayan
    Hi, I'm getting images from UIGetScreenImage() and storing directly in mutable array like:- image = [UIImage imageWithScreenContents]; [array addObject:image]; [image release]; I've set this code in timer so I cant use UIImagePNGRepresentation() to store as NSData as it reduces the performance. I want to use this array directly after sometime i.e after capturing 1000 images in 100 seconds. When I use the code below:- UIImage *im = [[UIImage alloc] init]; im = [array objectAtIndex:i]; UIImageWriteToSavedPhotosAlbum(im, nil, nil, nil); the application crashes. And I dont want to use UIImagePNG or JPGRepresentation() in timer as it reduces performance. My problem is how to use this array so that it is converted into image. If anybody has idea related to it please share with me. Thanks in Advance.

  • How to change a grouped UITableView cell's background to black (or non-white)?

    - by Meltemi
    Just want to make sure I'm not overlooking something obvious... It seems like it should be trivial to set the background color (black is fine) of a UITableView's cell to something other than white or completely transparent so that you can display your data with white text. However, with my attempts I lose the corners on my grouped table view and it all looks like crap. I've seen & understand the methods described by Matt Gallagher about customizing TableView cells with exotic gradients, etc. but wanted to be certain before heading down that path...

  • Core Location question....

    - by Moshe
    This tutorial on mobileorchard.com uses 2 classes (or 2 sets of .h and .m) to implement core location. Can I just use everything there in my existing class? How would I do that? Also, is the - (id) init { self = [super init]; if (self != nil) { self.locationManager = [[[CLLocationManager alloc] init] autorelease]; self.locationManager.delegate = self; // send loc updates to myself } return self; } method the same as the usual initWithNib? I;m trying to quickly implement something based on location information. As much help describing the above linked tutorial would be helpful. Thanks. No - really, Thank You.

  • NSNotificationCenter and ASIHTTPRequest

    - by user262325
    Hello everyone: I hope to get the http header info(file size) in asynchronous mode. So I initialize as codes: [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(processReadResponseHeaders:) name:@"readResponseHeaders" object:nil]; my codes to read the http header -(void)processReadResponseHeaders: (ASIHTTPRequest *)request ;//(id)sender; { unsigned long long contentLength = [request contentLength]; //error occurs here } It has to change the source code of ASIHTTPRequest.m I did add my codes in function readResponseHeaders to notify the event is triggered ) - (void)readResponseHeaders { //.........................

  • Dismissing UIImagePickerController from UITabBarController

    - by Dave
    I have a tab bar application whereby one tab uses a navigation controller to move through a series of views. On the final view, there is a button to add a photo, which presents a UIImagePickerController. So far, so good - however when I finish picking the image, or cancel the operation, the previous view is loaded, but without the tab bar. I'm sure I'm missing something elementary, but any suggestions on how to properly release the UIImagePickerController would be much appreciated. The code is as follows: ImagePickerViewController *aController = [[ImagePickerViewController alloc]; initWithNibName:@"ImagePickerViewController" bundle:[NSBundle mainBundle]]; [self presentModalViewController:aController animated:YES]; [aController release]; //viewDidLoad self.window = [[[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]] autorelease]; imagePickerController = [[UIImagePickerController alloc] init]; imagePickerController.delegate = self; if([UIImagePickerController isSourceTypeAvailable: UIImagePickerControllerSourceTypeCamera]){ imagePickerController.sourceType = UIImagePickerControllerSourceTypeCamera; } else { imagePickerController.sourceType = UIImagePickerControllerSourceTypePhotoLibrary; } [window addSubview:imagePickerController.view]; //ImagePickerViewController imagePickerControllerDidCancel - FinalViewController is the last view in the stack controlled by a navigation controller which contains the button to present the UIImagePickerController [picker dismissModalViewControllerAnimated:YES]; FinalViewController *aController = [[FinalViewController alloc initWithNibName:@"FinalViewController" bundle:[NSBundle mainBundle]]; [picker presentModalViewController:aController animated:YES]; [aController release];

  • Objective-C NSArray NEWBIE Question:

    - by clearbrian
    Hi I have a weird problems with NSArray where some of the members of the objects in my array are going out of scope but not the others: I have a simple object called Section. It has 3 members. @interface Section : NSObject { NSNumber *section_Id; NSNumber *routeId; NSString *startLocationName; } @property(nonatomic,retain) NSNumber *section_Id; @property(nonatomic,retain) NSNumber *routeId; @property(nonatomic,retain) NSString *startLocationName; @end @implementation Section @synthesize section_Id; @synthesize routeId; @synthesize startLocationName; //Some static finder methods to get list of Sections from the db + (NSMutableArray *) findAllSections:{ - (void)dealloc { [section_Id release]; [routeId release]; [startLocationName release]; [super dealloc]; } @end I fill it from a database in a method called findAllSection self.sections = [Section findAllSections]; In find all sections I create some local variables fill them with data from db. NSNumber *secId = [NSNumber numberWithInt:id_section]; NSNumber *rteId = [NSNumber numberWithInt:id_route]; NSString *startName = @""; Then create a new Section and store these local variable's data in the Section Section *section = [[Section alloc] init]; section.section_Id = secId; section.routeId = rteId; section.startLocationName = startName; Then I add the section to the array [sectionsArray addObject:section]; Then I clean up, releasing local variables and the section I added to the array [secId release]; [rteId release]; [startName release]; [locEnd_name release]; [section release]; In a loop repeat for all Sections (release local variables and section is done in every loop) The method returns and I check the array and all the Sections are there. I cant seem to dig further down to see the values of the Section objects in the array (is this possible) Later I try and retrieve one of the Sections I get it from the array Section * section = [self.sections objectAtIndex:row]; Then check the value NSLog(@" SECTION SELECTED:%@",section.section_Id); BUT call to section.section_Id crashed as section.section_Id is out of scope. I check the other members of this Section object and theyre ok. After some trial and error I find that by commenting out the release of the member variable the object is OK. //[secId release]; [rteId release]; [startName release]; [locEnd_name release]; [section release]; My questions are: Am I cleaning up ok? Should I release the object added to an array and the local variable in the function? Is my dealloc ok in Section? Does this code look ok and should I be looking elsewhere for the problem? I'm not doing anything complicated just filling array from DB use it in Table Cell. If its a stupid mistake then tell me (I did put NEWBIE on the question so dont be shocked it was asked) I can comment out the release but would prefer to know why or if code looks ok then ill need further digging. the only place that secId is released is in the dealloc. Thanks

  • Scroll UITableView so that the header isn't visible

    - by DASKAjA
    I've got a UITableView with a UISearchBar as the tableViews.tableHeaderView. Just like the new Mail.app, Notes.app, etc. in 3.0. I want to hide the SearchBar until the user drags it in his sight. My attempt only works when there're a couple of items in the tableView, so that the tableView actually wants to scroll. I call this in loadView: NSIndexPath *indexPath = [NSIndexPath indexPathForRow:0 inSection:0]; [self._tableView scrollToRowAtIndexPath:indexPath atScrollPosition:UITableViewScrollPositionTop animated:NO]; Nevertheless it seems that Apple handles such a serachbar differently. After draging out the searchbar it doesn't seem to be bounded to the tablecells anymore (in Notes.app, not in Mail.app). But perhaps Apple has a distinct method for that new 3.0 behaviour, and I just can't find it?

  • Get next record with Core Data

    - by Sebastian
    Hey, I have a tableview which content is managed through core data. When I select a row, a details view is pushed in and shows more information. How can I jump to the next record (the one below the one I selected in the tableview before) through a "next" button in the view ? Same for a previous button, but that should be very similar ... thx a lot ! Sebastian

  • Is this a tableView issue or a CoreData Issue

    - by monotreme
    I have a CoreData-driven navigation app and I'm trying to figure out why It's crashing. I've got a hierarchy which is 3 view Controllers deep, all related by coredata relatioships, like this. TableViewA =relationship= TableViewB =relationship= TableViewC I'm honestly a novice at core data and I think my problem lies in the fetched results controller. I have one in TableViewA and another in TableViewB, and no matter how deep I go, the console always cites TableViewB's fetched results controller methods after a crash. Is this the problem? What's happening specifically is if I launch my app and drill down into the hierarchy of one record, let's call it Record1, I can delete sub records to my hearts content. Gone! no problem! But the second I go back to TableViewA and drill down into a different record, let's call that one Record2, and try to delete it's subrecords my app crashes, with the console citing this code from TableViewB as the problem. - (void)controllerWillChangeContent:(NSFetchedResultsController *)controller { // The fetch controller is about to start sending change notifications, so prepare the table view for updates. [self.tableView beginUpdates]; } When I go into the debugger, the specific method it always has a problem with is: if (![x.managedObjectContext save:&error]) { NSLog(@"Unresolved error %@, %@", error, [error userInfo]); abort(); } Just a confirmation of my idiocy with CoreData is all I'm looking for I think. Oh and how many ManagedObjectContexts should I have in an app of this type. I've been told I should have separate ones for adding content, which then should re-integrate into the main one. Is this true? Thanks!

  • SKProductsRequest delegate methods are never called.

    - by coneybeare
    This used to work for me but is now not working anymore and I can't figure out why. I have in-app purchase setup in my app. I confirmed that I have a correct set of product identifiers, matched by corresponding in-app purchase items in itunesconnect. The call goes out to Apple view [productRequest start], but I never get a response back, despite setting the delegate to myself. What am I missing? NSLog(@"productIdentifiersSet: %@", productIdentifiersSet); if ([productIdentifiersSet count]) { SKProductsRequest *productRequest = [[SKProductsRequest alloc] initWithProductIdentifiers:productIdentifiersSet]; [productRequest setDelegate:self]; [productRequest start]; } ……… - (void)productsRequest:(SKProductsRequest *)request didReceiveResponse:(SKProductsResponse *)response { <never called> } - (void)requestDidFinish:(SKRequest *)request { <never called> } - (void)request:(SKRequest *)request didFailWithError:(NSError *)error { <never called> }

  • Best way to update badgeValue of UITabBarController from a UIView

    - by Rudiger
    Hi everyone, I have a tabBarController set up in the AppDelegate and have a few UIViewControllers with Nav Controllers. In one of the TabBar items, after I have pushed a few UIViews I want to update the badgeValue item of a different TabBar item. Whats the best way to do this? The only way I can really think is a NSNotification and a singleton storage for the value, but it seems a lot of work for something simple, that and I have no idea about NSNotifications. I had a wild guess at something like super.tabBarController.otherView.badgeValue = @"1" (as I set which tab is selected in a similar way) but I'm not surprised this doesn't work. Thanks

  • How to Unload a popped view controller?

    - by RexOnRoids
    Using a navigation based view hierarchy. I have a root view controller, and multiple view controllers that branch out from the same when a button is pressed. When a user presses the back button on the UINavigationBar, the current viewcontroller is popped and the display animates back to the rootviewcontroller. The problem is, I want the viewcontrollers to UNLOAD whenever they are popped. Seems like they are not unloading because when I go back to them they are still in the state they were when they were popped. How do I unload the viewcontrollers after navigating back to the rootviewcontroller?

  • What's a good way to remove all of the subviews of a UIScrollView?

    - by Moshe
    I have a scroll view and I need to reload the contents often while my app is running. Right now, I'm using the following line of code to remove the subviews before adding them back again: [scrollView.subviews makeObjectsPerformSelector:@selector(removeFromSuperview)]; Should I be using the following instead? scrollView.subviews = nil; For some reason, the (first) above line of code seems to crash the app every 16 times it is run. Am I leaking memory somewhere? The following method takes an array of views, the scroller (which is a constant) and the direction. Edit: - (void)loadViews:(NSArray *)views IntoScroller:(UIScrollView *)scroller withDirection:(NSString *)direction{ //Set up the scrollView [scrollView.subviews makeObjectsPerformSelector:@selector(removeFromSuperview)]; if([direction isEqualToString:@"horizontal"]){ scrollView.frame = CGRectMake(0, 0, 1024, 768); scrollView.contentSize = CGSizeMake(scrollView.frame.size.width * [[NSNumber numberWithUnsignedInt:[views count]] floatValue], scrollView.frame.size.height); }else if([direction isEqualToString:@"vertical"]){ scrollView.frame = CGRectMake(0, 0, 1024, 768); scrollView.contentSize = CGSizeMake(scrollView.frame.size.width, scrollView.frame.size.height * [[NSNumber numberWithUnsignedInt:[views count]] floatValue]); } for (int i=0; i<[[NSNumber numberWithUnsignedInt:[views count]] intValue]; i++) { [[[views objectAtIndex:[[NSNumber numberWithInt:i] unsignedIntValue]] view] setFrame:scrollView.frame]; if([direction isEqualToString:@"horizontal"]){ [[[views objectAtIndex:[[NSNumber numberWithInt:i] unsignedIntValue]] view] setFrame:CGRectMake(i * [[views objectAtIndex:[[NSNumber numberWithInt:i] unsignedIntValue]] view].frame.size.width, 0, scrollView.frame.size.width, scrollView.frame.size.height)];//CGRectMake(i * announcementView.view.frame.size.width, -scrollView.frame.origin.x, scrollView.frame.size.width, scrollView.frame.size.height)]; }else if([direction isEqualToString:@"vertical"]){ [[[views objectAtIndex:[[NSNumber numberWithInt:i] unsignedIntValue]] view] setFrame:CGRectMake(0, i * [[views objectAtIndex:[[NSNumber numberWithInt:i] unsignedIntValue]] view].frame.size.height, scrollView.frame.size.width, scrollView.frame.size.height)]; } [scrollView addSubview:[[views objectAtIndex:[[NSNumber numberWithInt:i] unsignedIntValue]] view]]; } }

  • Verifying existence of name and password in NSUserDefaults to Skip a login/Screen

    - by Michael Robinson
    I have a Tabbar/Tableview App that modally loads a Login/Signup view when the app loads, I have set up a Root.plist in a settings bundle for the name and password and have successfully retrieved the items. I want to be able to do two things: 1) Do a test to see if the NSUserDefault Strings are empty and if so load the Login/Signup view. 2) If the strings are available then use the string contents to login to my Webservice. Thanks in advance.
