  • How to save video from a url to disk, also how to begin playback after some buffering?

    - by Shizam
    First question is, given a url to an mp4 video, how can I save that file to disk? The followup to that is while its saving, can I begin playback after its buffered some of the video to disk or do I have to wait for the entire file to be written and then: MPMoviePlayerController* theMovie=[[MPMoviePlayerController alloc] initWithContentURL:theURL]; using the path to the local file. Thanks, Sam

  • Getting started with Festival on iphone

    - by Moshe
    I'd like to use Festival in an iPhone app. Is this possible, considering the way Festival generates and then plays back audio files? Can I pass Festival an audio file directly from itself to play back? or is there a different way to read things? Is there another Text-to-speech engine for C/C++ to use with iphone?

  • How can UISearchDisplayController autorelease cause crash in a different view controller?

    - by Tofrizer
    Hi, I have two view controllers A and B. From A, I navigate to view controller B as follows: // in View Controller A // navigateToB method -(void) navigateToB { BViewController *bViewController = [[BViewController alloc] initWithNibName: @"BView" bundle:nil]; bViewController.bProperty1 = SOME_STRING_CONSTANT; bViewController.title = @"A TITLE OF A VC's CHOOSING"; [self.navigationController pushViewController: bViewController animated:YES]; [bViewController release]; //<----- releasing 0x406c1e0 } In BViewController, the property bPropery1 is defined with copy as below (note, B also contains UITableView and other properties): @property (nonatomic, copy) NSString *bProperty1; Everything appeared to work fine when navigating back and forth between A and B. That is until I added a UISearchDisplayController to the table view contained in BViewController. Now when I navigate out of B, back to A, the app crashes. Stack trace shows what looks the search display controller being autoreleased at time of crash: #0 0x009663a7 in ___forwarding___ #1 0x009426c2 in __forwarding_prep_0___ #2 0x018c8539 in -[UISearchDisplayController _destroyManagedTableView] #3 0x018c8ea4 in -[UISearchDisplayController dealloc] #4 0x00285ce5 in NSPopAutoreleasePool NSZombies shows: -[BViewController respondsToSelector:]: message sent to deallocated instance 0x406c1e0 And malloc history on this points to the bViewController already released in A's navigateToB method above: Call [2] [arg=132]: thread_a065e720 |start ... <snip> ..._sendActionsForEvents:withEvent:] | -[UIControl sendAction:to:forEvent:] | - [UIApplication sendAction:to:from:forEvent:] | -[**AViewController navigateToB**] | +[NSObject alloc] | +[NSObject allocWithZone:] | _internal_class_createInstance | _internal_class_createInstanceFromZone | calloc | malloc_zone_calloc Can someone please give me any ideas on what is happening here? In navigateToB method, once the bViewController is released (after pushViewController), that's should be it for bViewController. Nothing else even knows about it as it is local to the navigateToB method block and it has been released. When navigating from B back to A, nothing is invoked in viewDidLoad, viewWillAppear etc that will re-enter navigateToB. It looks like somehow search display controller has a reference to something in my AViewController and so as it is autoreleased it is taking this "something" down with it but I cannot understand how this is possible, especially as I'm using copy to pass data between A and B. I'm going potty over this. I'm sure this is my mistake somewhere and so I turn to you, Stack Overflow legends for any words of wisdom or advice on how to resolve this. Many Thanks.

  • XCode 3.2 does not mark unit test assert failures in the editor

    - by Cliff
    I've been off in Java land for about a month or so and now, upon returning to XCode I feel lost. I've upgraded 1st to 3.1.2 then recently to 3.2 and also got a new Mac with Snow Leopard so I'm not exactly sure when the problem surfaced. I just know that I used to get little red bubbles in my unit test next to the failing asserts and that no longer seems to happen. Is there a way to restore this? I've been trying to use Apple's own SenTesting framework instead of GoogleTools for mac like I used to. Should I revert to Google Tools? Does anyone have an answer?

  • Core Data ANY BETWEEN predicate

    - by Mike Weller
    I'm trying to create an NSPredicate to find 'projects' that contain 'sessions' within a certain date range. I tried this at first: [NSPredicate predicateWithFormat:@"ANY sessions.date BETWEEN {$STARTDATE, $ENDDATE}"]; But I get an exception: *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: 'to-many key not allowed here' It seems BETWEEN does not work with ANY in this way. I'm also limited in use of () and AND clauses meaning I can't use something like: [NSPredicate predicateWithFormat:@"ANY (sessions.date > $STARTDATE && sessions.date < $ENDDATE)"]; If I try that I get a parse error. How can I do this? Thanks UPDATE: Note that this: [NSPredicate predicateWithFormat:@"ANY sessions.date > $STARTDATE && ANY sessions.date < $ENDDATE"]; Is incorrect because it returns a project where there is a session greater than the start date and another session less than the end date but no session in between.

  • Cross-Page communication in firefox extension

    - by OzBarry
    I have two tabs that my extension uses and I wanted to pass events back and forth between them. I've already developed a Google Chrome extension that does this via the background page api, but there doesn't seem to be an equivalent in firefox. I thought message-manager in the firefox extension docs would do the trick, but the documentation on the object is quite poor. I'd be just as happy with using one of the tabs to control the other if I can't directly import the ideas of a background page from google chrome api. Any help/guidance would be great.

  • For Loop Question?

    - by NextRev

  • OpenGL on the iPad

    - by Joe Cannatti
    I have an OpenGL project that is a universal project for iPhone/iPad. Basically it is just rendering simple models to the screen. It works great with no OpenGL errors on the iPhone device and iPad simulator. On the iPad device however, i get an OpenGL error and nothing renders. 1282 GL_INVALID_OPERATION immediately after calling [context renderbufferStorage:GL_RENDERBUFFER_OES fromDrawable:layer]; I can't seem to come up with any reason for this. Any help?

  • Are these AVAudioSettings right?

    - by Dyldo42
    self.recordSettings = [NSMutableDictionary dictionary]; [recordSettings setValue:[NSNumber numberWithInt:kAudioFormatAppleIMA4] forKey:AVFormatIDKey]; [recordSettings setValue:[NSNumber numberWithFloat:44100.0] forKey:AVSampleRateKey]; [recordSettings setValue:[NSNumber numberWithInt:1] forKey:AVNumberOfChannelsKey]; recordSettings is declared in my view's header file and initialised in its viewDidLoad method. For some reason, everything is working in the simulator, but on a device, the [recorder record] method is returning NO. The only theory I have is that something in the recordSettings isn't compatible with an actual device. Any ideas?

  • Circular Dependency of Navigation Control in iPhone

    - by Taimur Hamza
    Hi everyone , In my view this is one of the strangest problem i have ever come across in iPhone app development. Let me explain the scenario , i have main screen 'A' on which i have a Button that directs me to another Screen say 'B'. Now on Screen 'B' i have a feature in which user can send a mail to his friend for promotion purpose e.g a user wishes to tell a frnd about this app so i used MFMailComposeViewController and a view is generated where the user types the address and click send ( subject and body of mail is automatically generated ). After sending the mail a new view opens say screen 'C' and here i want to give the user the options . 1. Go to Screen 'A' ( which is main screen of the app ) 2. Go back to Screen 'B' ( from where the user requested to send a mail to his frnd ). Now the strange part i cannot declare the variables ( Screen 'A' and 'B' ) of both these files here at in header file of screen 'C' . Even when i declare the header file at the top it generates an error. The variables can be easily be declared and used for other screens but not for these 2 screens. Can anybody please explain wats the problem.? this the text of the error "/Users/admin/Documents/AppName/Classes/A.h:42: error: expected specifier-qualifier-list before 'B'" Thanks Guys ! Taimur

  • Android - Clicking on notification in status bar binds the intent with the target activity

    - by araja
    I have created an activity which sends a number of notifications to status bar. Each notification contains an intent with a bundle. Here is the code: String ns = Context.NOTIFICATION_SERVICE; NotificationManager mNotificationManager = (NotificationManager) getSystemService(ns); int icon = R.drawable.icon; long when = System.currentTimeMillis(); Notification notification = new Notification(icon, "Test Notification", when); Context context = getApplicationContext(); Bundle bundle = new Bundle(); bundle.putString("action", "view"); Intent notificationIntent = new Intent(this, MainActivity.class); notificationIntent.putExtras(bundle); PendingIntent contentIntent = PendingIntent.getActivity(this, 0, notificationIntent, Intent.FLAG_ACTIVITY_NEW_TASK); notification.setLatestEventInfo(context, contentTitle, contentText, contentIntent); mNotificationManager.notify(1, notification); When user clicks this notifications, I read the bundle string "action" and performs that action. Here is the code: Bundle bundle = this.getIntent().getExtras(); if(bundle != null) { String action = bundle.getString("action"); performAction(action) } Everything works as expected. But, when I minimize the app using "arrow" button on device and then press and hold home button and clicks on my app icon the application starts and performs the same last action which have been performed by clicking the last notification. I figured out that when we click the app icon the application starts with last intent triggered by the notification. Can anyone help in this?

  • How do I draw a proper parallelogram that can be animated on iPhone?

    - by Robert Kosara
    I'm trying to do something very simple: I need some parallelograms in my program. These are attached to other objects, all of which are UIViews. It's important that I be able to animate these, since the objects they are attached to can also be animated. I've figured out how to use the transform in UIView/CALayer to do this, but the problem is that these sheared UIViews don't look very nice: there is no anti-aliasing of the edges. Is there some other way to do this? I would like to use UIViews, since I also use them for user interaction and animation is so much easier than drawing by hand. I don't want to use OpenGL for this.
