  • Getting the Value of a UITextField as keystrokes are entered?

    - by Nocturne
    Let's say I have the following code: IBOutlet UITextField* nameTextField; IBOutlet UILabel* greetingLabel; I'd like the greetingLabel to read "Hello [nameTextField]" as soon as the user presses any key. What I need basically is the iPhone equivalent of the Cocoa delegate method -controlTextDidChange: The -textField:shouldChangeCharactersInRange: delegate method is called each time a keystroke occurs: - (BOOL) textField:(UITextField *)textField shouldChangeCharactersInRange:(NSRange)range replacementString:(NSString *)string The string argument returns the character that is pressed. The actual textField's value (nameTextField.text) remains blank however. What am I missing here? (I'd like nameTextField to reflect the exact string that the user has entered so far)

  • Push notifications work for Ad Hoc, but not when downloaded from the Apple store.

    - by MikeQ
    My app just got approved for the apple store. I downloaded it an installed it on my iPhone - but it looks like push notifications are broken! I was successfully testing push notifications in production using an adHoc provisioning profile. I had no problems. The only thing I did differently when I submitted to apple was using an app store distribution profile. The application never asks me (or anyone else who has downloaded it) if I want to receive push notifications. Consequently, the phone never talks to my server to send the push token (because application:didRegisterForRemoteNotificationsWithDeviceToken: is presumably never called). Also the application does not appear in the settings app under the notification settings. What could I be doing wrong??

  • Setting Priorities on Bottons

    - by JONY
    Hello Android Developers, I am trying to figure out how to set priorities on imagebutton. I want to have a layout with a bunch of Icon or buttons that can be selected either by touch, radio, or checked box. As these images are selected they are set on queue to be displayed in order of Precedence. (that is to be pre-determined). The images are displayed once the main action button is touched. Any help will be greatly appreciated. Thank you,

  • Making large toolbars like the iPod app

    - by andybee
    I am trying to create a toolbar programatically (rather than via IB) very similar to the toolbar featured in the iPhone app. Currently I've been experimenting with the UIToolbar class, but I'm not sure how (and if?) you can make the toolbar buttons centrally aligned and large like that in the iPod app. Additionally, regardless of size, the gradient/reflection artwork never correctly respects the size and is stuck as if the object is the default smaller size. If this cannot be done with a standard UIToolbar, I guess I need to create my own view. In this case, can the reflection/gradient be created programmatically or will it require some clever alpha tranparency Photoshopped artwork?

  • Problems when handling orientation changes

    - by nixau
    Hi all, I need to handle orientation changes in my Android application. For this purpose I decided to use OrientationEventListener convenience class. But his callback method is given somewhat strange behavior. My application starts in the portrait mode and then eventually switches to the lanscape one. I have some custom code executing in the callback onOrientationChanged method that provides some additional UI handling logic - it has a few calls to findViewById. What is strange is that when switching back from landscape to portrait mode onOrientationChanged callback is called twice, and what's even worse - the second call is dealing with bad Context - findViewById method starts returning null. These calls are made right from the MainThread @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); listener = new OrientationListener(); } @Override protected void onResume() { super.onResume(); // enabling listening listener.enable(); } @Override protected void onPause() { super.onPause(); // disabling listening listener.disable(); } I've replicated the same behavior with a dummy Activity without any logic except for one that deals with orientation hadling. I initiate orientation switch from the Android 2.2 emulator by pressing Ctrl+F11 What could be wrong? Upd: Inner class that implements OrientationEventListener private class OrientationListener extends OrientationEventListener { public OrientationL() { super(getBaseContext()); } @Override public void onOrientationChanged(int orientation) { toString(); } } }

  • Problem generating APN SSL certificate after submitting to apple store

    - by MikeQ
    I'm having trouble getting Apple to generate an APN SSL certificate for my app ID. I've submitted the application to the Apple store, and it is pending review. I tested the application using an Ad Hoc app ID "${bundle_id}.adHoc" and everything went fine. I submitted to the Apple store with app ID "${bundle_id}.release". Now I want to generate my production APN SSL certificate for use with my release application ID - but the developer portal doesn't want to. When I upload my certificate request, it sits for about a minute before telling me: "We are not able to generate your Profile at this time. Please try again later or try using the Provisioning Portal" Is it impossible to generate your certificate while the application is under review or something? Should I have generated it prior to submission?

  • Core data setReturnsDistinctResult not working

    - by Moze
    So i'm building a small application, it uses core data database of ~25mb size with 4 entities. It's for bus timetables. In one table named "Stop" there are have ~1300 entries of bus stops with atributes "name", "id", "longitude", "latitude" and couple relationships. Now there are many stops with same name but different coordinates and id. Search is implemented using NSPredicate. So I want to show all distinct stop names in table view, i'm using setReturnsDistinctResults with NSDictionaryResultType and setPropertiesToFetch. But setReturnsDistinctResult is not working and I'm still getting all entries. Heres code: - (NSFetchRequest *)fetchRequest { if (fetchRequest == nil) { fetchRequest = [[NSFetchRequest alloc] init]; NSEntityDescription *entity = [NSEntityDescription entityForName:@"Stop" inManagedObjectContext:managedObjectContext]; [fetchRequest setEntity:entity]; NSArray *sortDescriptors = [NSArray arrayWithObject:[[[NSSortDescriptor alloc] initWithKey:@"name" ascending:YES] autorelease]]; [fetchRequest setSortDescriptors:sortDescriptors]; [fetchRequest setResultType:NSDictionaryResultType]; [fetchRequest setPropertiesToFetch:[NSArray arrayWithObject:[[entity propertiesByName] objectForKey:@"name"]]]; [fetchRequest setReturnsDistinctResults:YES]; DebugLog(@"fetchRequest initialized"); } return fetchRequest; } ///////////////////// - (NSFetchedResultsController *)fetchedResultsController { if (self.predicateString != nil) { self.predicate = [NSPredicate predicateWithFormat:@"name CONTAINS[cd] %@", self.predicateString]; [self.fetchRequest setPredicate:predicate]; } else { self.predicate = nil; [self.fetchRequest setPredicate:predicate]; } fetchedResultsController = [[NSFetchedResultsController alloc] initWithFetchRequest:self.fetchRequest managedObjectContext:managedObjectContext sectionNameKeyPath:sectionNameKeyPath cacheName:nil]; return fetchedResultsController; } ////////////// - (UITableViewCell *)tableView:(UITableView *)table cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *CellIdentifier = @"Cell"; UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier]; if (cell == nil) { cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease]; } cell.textLabel.text = [[fetchedResultsController objectAtIndexPath:indexPath] valueForKey:@"name"]; return cell; }

  • MPMoviePlayerController problem at start

    - by Infinity
    Hello guys! I have a problem with MPMoviePlayerController, because when I start it in fullscreen it exists, but the song is still playing. I added the MPMoviePlayerDidExitFullscreenNotification notification and it says that when the video starts playin it exists the full screen. Here's my code: _multimediaPlayer = [[MPMoviePlayerController alloc] init]; _multimediaPlayer.controlStyle = MPMovieControlStyleDefault; _multimediaPlayer.initialPlaybackTime = 0; [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(videoPlayBackDidFinish:) name:MPMoviePlayerPlaybackDidFinishNotification object:nil]; [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(videoPlayerDidExitFullscreen:) name:MPMoviePlayerDidExitFullscreenNotification object:nil]; [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(videoPlayerPlaybackStateChanged:) name:MPMoviePlayerPlaybackStateDidChangeNotification object:nil]; NSString *path = [NSString stringWithFormat:@"%@/mag_%d/%@", [FMUtils documentsFolderPathWithFile:nil], _magID, _pageObject.fileName]; if ([FMUtils fileExistsAtPath:path]) { _multimediaPlayer.contentURL = [NSURL fileURLWithPath:path]; } else { _multimediaPlayer.contentURL = [NSURL URLWithString:[NSString stringWithFormat:@"%@%@", self.dataURL, _pageObject.fileName]]; } CGSize objectViewSize = self.frame.size; _multimediaPlayer.view.frame = CGRectMake(0, 0, objectViewSize.width, objectViewSize.height); [self addSubview:_multimediaPlayer.view]; if (_pageObject.blink) { [_multimediaPlayer setFullscreen:YES animated:YES]; } [_multimediaPlayer play]; Most of the time it happens when the video is not downloaded and it needs to stream it. Do you have any idea why is this happen?

  • How can I programmatically add more than just one view object to my view controller?

    - by BeachRunnerJoe
    I'm diving into iPhone OS development and I'm trying to understand how I can add multiple view objects to the "Left/Root" view of my SplitView iPad app. I've figured out how to programmatically add a TableView to that view based on the example code I found in Apple's online documentation... RootViewController.h @interface RootViewController : UITableViewController <NSFetchedResultsControllerDelegate, UITableViewDelegate, UITableViewDataSource> { DetailViewController *detailViewController; UITableView *tableView; NSFetchedResultsController *fetchedResultsController; NSManagedObjectContext *managedObjectContext; } RootViewController.m - (void)loadView { UITableView *newTableView = [[UITableView alloc] initWithFrame:[[UIScreen mainScreen] applicationFrame] style:UITableViewStylePlain]; newTableView.autoresizingMask = UIViewAutoresizingFlexibleHeight|UIViewAutoresizingFlexibleWidth; newTableView.delegate = self; newTableView.dataSource = self; [newTableView reloadData]; self.view = newTableView; [newTableView release]; } but there are a few things I don't understand about it and I was hoping you veterans could help clear up some confusion. In the statement self.view = newTableView, I assume I'm setting the entire view to a single UITableView. If that's the case, then how can I add additional view objects to that view alongside the table view? For example, if I wanted to have a DatePicker view object and the TableView object instead of just the TableView object, then how would I programmatically add that? Referencing the code above, how can I resize the table view to make room for the DatePicker view object that I'd like to add? Thanks so much in advance for your help! I'm going to continue researching these questions right now.

  • Problem with entityForName & ManagedObjectContext when extending tutorial material

    - by Martin KS
    Afternoon all, I tried to add a second data entity to the persistent store in the (locations) coredata tutorial code, and then access this in a new view. I think that I've followed the tutorial, and checked that I'm doing a clean build etc, but can't see what to change to prevent it crashing. I'm afraid I'm at my wits end with this one, and can't seem to find the step that I've missed. I've pasted the header and code files below, please let me know if I need to share any more of the code. The crash seems to happen on the line: NSEntityDescription *entity = [NSEntityDescription entityForName:@"Album" inManagedObjectContext:[self managedObjectContext]]; There is one other line in the code that refers to galleryviewcontroller at the moment, and that's in the main application delegate: galleryViewController.managedObjectContext = [self managedObjectContext]; GalleryViewController.h #import <UIKit/UIKit.h> @interface GalleryViewController : UIViewController { NSManagedObjectContext *managedObjectContext; int rowNumber; IBOutlet UILabel *lblMessage; UIBarButtonItem *addButton; NSMutableArray *imagesArray; } @property (readwrite) int rowNumber; @property (nonatomic,retain) UILabel *lblMessage; @property (nonatomic,retain) NSMutableArray *imagesArray; @property (nonatomic, retain) NSManagedObjectContext *managedObjectContext; @property (nonatomic, retain) UIBarButtonItem *addButton; -(void)updateRowNumber:(int)theIndex; -(void)addImage; @end GalleryViewController.m #import "RootViewController.h" #import "LocationsAppDelegate.h" #import "Album.h" #import "GalleryViewController.h" #import "Image.h" @implementation GalleryViewController @synthesize lblMessage,rowNumber,addButton,managedObjectContext; @synthesize imagesArray; /* // The designated initializer.

  • UIView frame origin doesn't set good

    - by Infinity
    Hi guys! Here is my code: frame = _pageContentView.frame; NSLog(@"%f; %f; %f; %f;", frame.origin.x, frame.origin.y, frame.size.width, frame.size.height); frame.size.height = pageContentView.frame.size.height; NSLog(@"%f; %f; %f; %f;", frame.origin.x, frame.origin.y, frame.size.width, frame.size.height); _pageContentView.frame = frame; NSLog(@"%f; %f; %f; %f;", _pageContentView.frame.origin.x, _pageContentView.frame.origin.y, _pageContentView.frame.size.width, _pageContentView.frame.size.height); And the NSLog outputs these values: 0.000000; 0.000000; 317.648956; 0.000000; 0.000000; 0.000000; 317.648956; 768.000000; 0.000007; 0.000004; 317.648956; 768.000000; Can you see? In the last row the x and y coordinates are a bit crazy... Where do these number come frome? What's the problem here?

  • Setting UITableViewCell button image values during scrolling

    - by Rob
    I am having an issue where I am trying to save whether a repeat image will show selected or not (it is created as a UIButton on a UITableViewCell created in IB). The issue is that since the cell gets re-used randomly, the image gets reset or set somewhere else after you start scrolling. I've looked all over and the advice was to setup an NSMutableArray to store the button's selection state and I am doing that in an array called checkRepeatState My question is: where do I put the if-then-else statement in the code to where it will actually change the button image based on if the checkRepeatState is set to 0 or 1 for the given cell that is coming back into view? Right now, the if-then-else statement I am using has absolutely no effect on the button image when it comes into view. I'm very confused at this point. Thank you ahead of time for any insight you can give!!! My code is as follows: - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { // set up the cell static NSString *CellIdentifier = @"PlayerCell"; PlayerCell *cell = (PlayerCell *)[tableView dequeueReusableCellWithIdentifier:CellIdentifier]; if (!cell) { [[NSBundle mainBundle] loadNibNamed:@"PlayerNibCells" owner:self options:nil]; cell = tmpCell; self.tmpCell = nil; NSLog(@"Creating a new cell"); } // Display dark and light background in alternate rows -- see tableView:willDisplayCell:forRowAtIndexPath:. cell.useDarkBackground = (indexPath.row % 2 == 0); // Configure the data for the cell. NSDictionary *dataItem = [soundCategories objectAtIndex:indexPath.row]; UILabel *label; label = (UILabel *)[cell viewWithTag:1]; label.text = [dataItem objectForKey:@"AnimalName"]; label = (UILabel *)[cell viewWithTag:2]; label.text = [dataItem objectForKey:@"Description"]; UIImageView *img; img = (UIImageView *)[cell viewWithTag:3]; img.image = [UIImage imageNamed:[dataItem objectForKey:@"Icon"]]; NSInteger row = indexPath.row; NSNumber *checkValue = [checkRepeatState objectAtIndex:row]; NSLog(@"checkValue is %d", [checkValue intValue]); // Reusing cell; make sure it has correct image based on checkRepeatState value UIButton *repeatbutton = (UIButton *)[cell viewWithTag:4]; if ([checkValue intValue] == 1) { NSLog(@"repeatbutton is selected"); [repeatbutton setImage:[UIImage imageNamed:@"repeatselected.png"] forState:UIControlStateSelected]; [repeatbutton setNeedsDisplay]; } else { NSLog(@"repeatbutton is NOT selected"); [repeatbutton setImage:[UIImage imageNamed:@"repeat.png"] forState:UIControlStateNormal]; [repeatbutton setNeedsDisplay]; } cell.accessoryType = UITableViewCellAccessoryNone; return cell; }

  • Any way to trigger interface orientation check?

    - by Johnny Tee
    My app is going from a flipside view (only one orientation) to its main view (can have any sort of orientation. When I go from flipside back to main view, the main view's orientation is not checked and changed immediately. I need a way to trigger the built in orientation check that happens in willRotateToInterfaceOrientation so that the orientation is correct when the user goes from flipside view to main view. Any help is appreciated. I saw another question about this but didn't see a definitive answer. Thanks!

  • Display shift when adding rows to UITableView

    - by Kamchatka
    Hello, I have a UITableView displaying an underlying NSFetchedResultsController. When the fetchedResultsController is updated, - (void)controller:(NSFetchedResultsController *)controller didChangeObject:(id)anObject atIndexPath:(NSIndexPath *)indexPath forChangeType:(NSFetchedResultsChangeType)type newIndexPath:(NSIndexPath *)newIndexPath { is called. And the following is executed: case NSFetchedResultsChangeInsert: [tableView insertRowsAtIndexPaths:[NSArray arrayWithObject:shiftedIndexPath] withRowAnimation:UITableViewRowAnimationFade]; break; The cellForRowAtIndexPath is only called for the new line (which is logical) The problem is however that all the values displayed in the rows of the table view are shifted down. The first row displays its title. The second rows displays the first row's title. The third row the second row's title etc. If I repeat that, the third row will display the second's row title, the fourth the third row's title etc. I don't understand what can happen, especially because cellForRowAtIndexPath is only called for the new line (which is logical) and not for all these lines. Additionally, if I click on these lines which have the wrong title, it opens the right document (didSelectRowAtIndexPath works correctly with the indexPath) Any clue of what could happen? Thanks!

My app relies on a user defined server url and I would like to be able to set a URL scheme to launch my app using the users custom URL from lets say an email link. I noticed the info.plist has these references ${EXECUTABLE_NAME} can I define my own custom reference maybe?

  • iPhone: Push Navigation Controller (w/ TableViewController) onto stack. Is this possible?

    - by Nic Hubbard
    I have a view which contains a UIButton. When this is clicked, it calls a method that loads another NIB. Now, normally, that nib would load a view onto the stack, and everything would be fine. But, I am trying to load a Navigation Controller (so that I can have table views that are multiple levels deep), and all I get it errors. What is the proper method for loading a Navigation Controller and putting it on the top of the stack?

  • Assigning to struct in different class

    - by 4thSpace
    I have a struct in ClassA and want to assign it to the same struct in ClassB (the two structs are the same with different names). ClassA and ClassB are view controllers. Basically, I need to pass this struct to another class. However, structs don't seem to be exposed as members, which means I can't access them. Here is ClassA's struct declared in its header file: typedef struct { NSString *startDate; NSString *endDate; NSString *classId; } selectedItemsClassAStruct; selectedItemsClassAStruct selectedItemsClassA; and the same for ClassB (just with ClassA text replaced) It doesn't appear in code hints for ClassB. I see this error if I try to access it: request for member 'selectedItemsClassBStruct' in something not a structure or union How should it be done?
