  • Determine iPhone user's country

    - by alku83
    I need to determine at startup what country a user is in, for an iPhone application. Presumably I will have to turn on location services and do some sort of reverse geocoding. I don't really want to use a third party web service if possible, are there any other suggestions for determining country from what location services provides? Initially, I only need to check whether the user is inside the US or not, but this may change in the future to add more countries. I understand that location can not always be determined or the user may have location services turned off. Basically, I just need to know if the user is detected as being inside the US, in order to turn off a specific feature.

  • AVAudioPlayer won't play audio file after AVAudioRecorder

    - by Kevin
    I create a .caf audio file using AVAudioRecorder and if I try and play it back using AVAudioPlay I get no sound on the iPhone (if played in simulator works fine). If I close my application and reopen the file plays fine. Also I am not able to adjust the phone volume after recording unless I close and reopen my application. Any ideas?

  • custom button: properties change, button should be redrawn

    - by Rutger
    Hi I'm developing an Android app. I have class derived from button to represent a special type of button. This special type has some properties (integers) and according to these one or more circles have to be drawn on top of the button. So I overrode the onDraw function, which looks the values up and accordingly draws the circles. But the class has a function to set new values for its properties. So new values are set but the changes are not reflected in the UI. It seems like the onDraw function is not called. When later I click the button or show a pop up message above my interface the onDraw function is called and the button is drawn correctly. So my question: when changing the properties how can I say that the button has to be redrawn? Thanks a lot!

  • Android horizontal scrolling showing Cursor data

    - by androidharry
    I have some text data in database which I have retrieved in a Cursor, and I am displaying it in a ListView. What I want to do now is that when you select click a particular row in the list its text content should be displayed in full screen and the user should be able to scroll horizontally (like scrolling between iPhone home screens) to view the contents of the Cursor.

  • Adding a dynamic image to UITable View Cell

    - by Graeme
    Hi, I have a table in which I want a dynamic image to load in at the left-hand side. The table needs to use an IF statement to select the appropriate image from the "Resources" folder, and needs to be based upon [dog types]. The [dog types] is extracted from an RSS feed, and so the image in the table cell needs to match the each cell's [dog types] tag. Update: See code below for what I'm looking to do (only below it's for earthquakes, for me its pictures of dogs). I suspect I need to use - (UIImage *)imageForTypes:(NSString *)types { to do such a thing. Thanks. Updated code: This is for Apple's Earthquake sample but does exactly what I need to do. It matches images to the severity (2.0, 3.0, 4.0, 5.0 etc.) of every earthquake to the magnitude. - (UIImage *)imageForMagnitude:(CGFloat)magnitude { if (magnitude >= 5.0) { return [UIImage imageNamed:@"5.0.png"]; } if (magnitude >= 4.0) { return [UIImage imageNamed:@"4.0.png"]; } if (magnitude >= 3.0) { return [UIImage imageNamed:@"3.0.png"]; } if (magnitude >= 2.0) { return [UIImage imageNamed:@"2.0.png"]; } return nil; } and under - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath magnitudeImage.image = [self imageForMagnitude:earthquake.magnitude];

  • iPhone: Remove annotation from MKMapView which is in another view

    - by Nic Hubbard
    I have two views. The first is a MKMapView with some annotations. Clicking a UIButton pushes a second view on the stack. This has a UITableView with a list of annotations which correspond to the map annotations. So, when you click the delete button, how can I call my MKMapView which is in another view, so that I can remove the annotation. My MKMapView is declared in my app delegate, as well as my current class. I am trying to use the following, but it is not working: RideAppDelegate *appDelegate = (RideAppDelegate *)[[UIApplication sharedApplication] delegate]; Annotation *ano; CLLocationCoordinate2D anoPoint; anoPoint.latitude = [[eventToDelete valueForKey:@"latitude"] doubleValue]; anoPoint.longitude = [[eventToDelete valueForKey:@"longitude"] doubleValue]; ano = [[[Annotation alloc] init] autorelease]; ano.coordinate = anoPoint; [appDelegate.ridesMap removeAnnotation: ano]; [appDelegate release]; I must be trying to access the MKMapView of my other view incorrectly?

  • Can I disable UIPickerView scroll sound?

    - by cocoaholic
    Hi, I want to disable the annoying clicks that the UIPickerView generates upon scrolling up and down. Is there a way to do this? I want to play short sounds for each item that the picker view lands upon. It gets ruined by the built in sound. I understand that the picker sounds can be turned off globally by switching off the keyboard sounds in iPhone/iPod settings. But is there a way to programatically do this? Any help will be much appreciated! Thanks

  • UIAlertView won't rotate to landscape even with applicationDidFinishLaunching call

    - by Joey
    I am trying to use UIAlertView on my landscape right (home button on the right) app but it is showing up in portrait orientation. I have tried putting: [[UIApplication sharedApplication] setStatusBarOrientation: UIInterfaceOrientationLandscapeRight animated: NO ]; in applicationDidFinishLaunching, but it doesn't work. Are there any other usual suspects to what might be causing this? I am setting the orientation through my plist file currently.

  • 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.

  • 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

  • What call from the Android Development Tools API should I use to poll project target loading?

    - by Ricardo Gladwell
    I'm writing my own eclipse plug-in that integrates with the Eclipse Android Development Tools (ADT). However, I'm getting a CoreException ("Project target not loaded yet.") thrown when I attempt to call IProject.build on an Android project as part of a unit test: IProject project = importProject(...); project.build(IncrementalProjectBuilder.FULL_BUILD, monitor); Should I be waiting for the project target to load before calling the above? If so, what call should I use to poll the project target loading status?

  • Reading iTunesMovies file in iPhone?

    - by raziiq
    Hi there. In iPhone, the iPod app saves the media files (audio, video) with strange names and in weird folders (F00,F01 etc). There is a file named iTunesMovies in iPhone, which contains all the information about the metadata of those video files and how they are to be displayed in iPod app. I copied that to my Mac also, and when i tried to open that file in textEdit, it showed some alien characters which made me believe that it is encrypted may be(Thats just a wild guess). I want to read/change the contents of that iTunesMovies file. Can i do that? Is there any Framework which deals with that iTunesMovies file? Thanks in advance
