  • 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?

    - by Adam Driscoll
    I have an interface: public interface X {} I have a class: public class Y : X {} I have one cmdlet: [Cmdlet("Get", "Y")] public class GetYCmdlet : PSCmdlet { protected override void ProcessRecord() { WriteObject(new Y()); } } I have another cmdlet: [Cmdlet("Set", "X")] public class SetYCmdlet : PSCmdlet { [Parameter] public X SomeObj {get;set;} } When I do this: $y = Get-Y Set-X -SomeObj $y I get this: Could not convert "Y" to "X".

  • 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!

  • 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?

  • how can load images from plist in to UITableView ?

    - by srikanth rongali
    I have stored the videos and the thumbnail images of the videos in Documents folder. And I have given the path in plist. In plist I took an array and I added directories to the array. And in the dictionary I stored the image path /Users/srikanth/Library/Application Support/iPhone Simulator/User/Applications/9E6E8B22-C946-4442-9209-75BB0E924434/Documents/image1 for key imagePath. for video /Users/srikanth/Library/Application Support/iPhone Simulator/User/Applications/9E6E8B22-C946-4442-9209-75BB0E924434/Documents/video1.mp4 for key filePath. I used following code but it is not working. I am trying only for images. I need the images to be loaded in the table in each cell. - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *CellIdentifier = @"Cell"; UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier]; if (cell == nil) { cell = [[[UITableViewCell alloc] initWithFrame:CGRectZero reuseIdentifier:CellIdentifier] autorelease]; [cell setAccessoryType:UITableViewCellAccessoryDetailDisclosureButton]; UIImageView *image2 = [[UIImageView alloc]init]; image2.frame = CGRectMake(0.0f, 0.0f, 80.0f, 80.0f); image2.backgroundColor = [UIColor clearColor]; //image2.image = [UIImage imageNamed:@"snook.png"]; image2.tag = tag7; } NSDictionary *dictOfplist = [cells objectAtIndex:indexPath.row]; [(UIImageView *)[cell viewWithTag:tag7] setImage:[dictOfplist objectForKey:@"imagePath"]]; return cell; } - (void)viewDidLoad { [super viewDidLoad]; self.title = @"Library"; self.navigationItem.rightBarButtonItem = [[UIBarButtonItem alloc] initWithTitle:@"Close" style:UIBarButtonItemStyleBordered target:self action:@selector(close:)]; NSString* plistPath = [[NSBundle mainBundle] pathForResource:@"details" ofType:@"plist"]; contentArray = [NSArray arrayWithContentsOfFile:plistPath]; cells = [[NSMutableArray alloc]initWithCapacity:[contentArray count]]; for(dCount = 0; dCount < [contentArray count]; dCount++) [cells addObject:[contentArray objectAtIndex:dCount]]; } How can I make this work. Thank you.

  • iPhone accelerometer:didAccelerate: seems to not get called while I am running a loop

    - by AJ
    An accelerometer related question. (Sorry the formatting may not look right, its the first time I am using this site). I got the accelerometer working as expected using the standard code UIAccelerometer *accel = [UIAccelerometer sharedAccelerometer]; accel.delegate = self; accel.updateInterval = 0.1; //I also tried other update values I use NSLog to log every time the accelerometer:didAccelerate: method in my class is called. The function gets called as expected and everything works fine till here. However, when I run a loop, the above method doesn't seem to get called. Something like this float firstAccelValue = globalAccel; //this is the x-accel value (stored in a global by the above method) float nextAccelValue = firstAccelValue; while (nextAccelValue == firstAccelValue){ //do something nextAccelValue = globalAccel; // note globalAccel is updated by the accelerometer method } The above loop never exits, expectedly since the accelerometer:didAccelerate: method is not getting called, and hence globalAccel never changes value. If I use a fixed condition to break the while loop, I can see that after the loop ends, the method calls work fine again. Am I missing something obvious here? Or does the accelerometer method not fire when certain processing is being done? Any help would be greatly appreciated! Thanks!

  • 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.

  • OpenGL ES, UIView and Status Bar mess

    - by sfider
    I have iPhone (iPhoneOS 3.x) OpenGL ES app that: can be in landscape/portrait orientation can be with/without status bar shown I do this by changing status bar orientation and hidden state, then updating OpenGL view frame so it won't overlap status bar and setting projection matrix appropriately. OpenGL view is in portrait orientation at all time. View controller's shouldAutorotateToInterfaceOrientation: method returns false always, so the status bar won't start autorotating when app is in landscape mode. The problem I have is that I want to use some other UIViews, like: UIWebView, MFMailComposeView, MPMediaPicker. I could show them as modals, but this this have some drawbacks: views will always show in portrait orientation, even if they support landscape orientation views will not autorotate, even if they support it What I do is I take OpenGL view of the window with removeFromSuperview, set transform to the other view so it will be in portrait/landscape orientation when it shows up and place the other view on the window with addSubview:. This works fine without the status bar, but with it there are some problems I cannot work out: MPMediaPicker is sized to fit under status bar, but it slides under it anyway MFMailComposeView does not show navigation bar until it autorotates on device orientation change Does anyone has an idea how can I get it to work?

  • 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

  • Background image for list view still shows white behind text for cells.

    - by MonkeyTroy
    I wanted to put a background image partially visible behind a list view. I created a list view in my nib with an image view behind it and made the list view background 20% opacity. This allows the background image to show thru but my text in the cells show a white background behind and if I create the cells in cellForRowAtIndexPath the cells have a white background too. I am creating and setting the cell textLabel and the detailTextLabel in the cellForRowAtIndexPath event. Not sure how to get rid of that, or if there is a better way to do the background image.

  • 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.

  • How to set NSZombieEnabled for debugging EXC_BAD_ACCESS on release target for an iPhone app?

    - by Bobby Moretti
    I'm developing an iPhone application. I have an EXC_BAD_ACCESS that occurs only in the release target; when I build the debug target the exception does not occur. However, when I set the NSZombieEnabled environment variable to YES, I still get the EXC_BAD_ACCESS with no further information. Is it even possible for NSZombieEnabled to work when executing the release target? I don't see why not, since gdb is running in both cases...

  • 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?
