• SubViewTwoController undeclared (first use in this function) (obj-c)

  - by benny

  Ahoy hoy everyone :) Here is a list of links. You will need it when reading the post. I am a newbie to Objective-C and try to learn it for iPhone-App-Development. I used the tutorial linked in the link list to create a standard app with a simple basic Navigation. This app contains a "RootView" that is displayed at startup. The startup screen itself contains three elements wich all link to SubViewOne. I have got it to work this far. So what i want to change is to make the second element link to SubViewTwo. When i "Build and Go" it, i get the following errors: RootViewController.m: SubViewTwoController *subViewTwoController = [[SubViewTwoController alloc] init]; // SubViewTwoController undeclared (first use in this function) and in SubViewTwoController.m [super didReceiveMemoryWarning]; // Releases the view if it doesn't have a superview no superclass declared in @interface for ´SubViewTwoController´ and the same thing after - (void)dealloc { [super dealloc]; I think you will also need the header files, so here they are! RootViewController.h #import <UIKit/UIKit.h> @interface RootViewController : UITableViewController { IBOutlet NSMutableArray *views; } @property (nonatomic, retain) IBOutlet NSMutableArray *views; @end SubViewOneController.h #import <UIKit/UIKit.h> @interface SubViewOneController : UIViewController { IBOutlet UILabel *label; IBOutlet UIButton *button; } @property (retain,nonatomic) IBOutlet UILabel *label; @property (retain,nonatomic) IBOutlet UIButton *button; - (IBAction) OnButtonClick:(id) sender; @end and SubViewTwoController.h #import <UIKit/UIKit.h> @interface SubViewTwo : UIViewController { IBOutlet NSMutableArray *views; } @end I would be really great if you would leave your ideas with a short explanation. Thanks a lot in advance! benny

• Mapkit +closest annotation

  - by danskcollignon

  Hi all, I am trying to devellopp an app showing the nearest poi to the users location. My app is now capable of: showing a map (Mapkit) with 110 annotations and the user's location. Furthermore, I have a TableView at the bottom of my screen, to choose between the different annotations. However, they're listed by number, and not by proximity to the user's location, which is my wish. My research have led me to think that I should use CLLocation for getting the user's location. I then have really no idea on how to do it next, using getDistancefrom. My annotations are stored on SecondViewController.m, using this form: -(void)loadOurAnnotations { CLLocationCoordinate2D workingCoordinate; workingCoordinate.latitude = XX.XXXXX; workingCoordinate.longitude = XX.XXXXX; SecondViewAnnotation *POI1 = [[SecondViewAnnotation alloc] initWithCoordinate:workingCoordinate]; [POI1 setTitle:@"POI"]; [POI1 setSubtitle:@"StreetName"]; [POI1 setAnnotationType:SecondViewAnnotationTypePOI1]; [mapView addAnnotation:POI1]; , and so on to POI110. Could someone please give me a clue? I'm a total newbie! Thank you in advance for your help,

• XCode Obj-C: Make new NSArray from one key each out of an Array of Dictionaries

  - by user323772

  This actually could be a multipart question. But here's the first part ... I have an array (actually in a plist) of dictionaries. Each dictionary has 3 keys in it: (title), (points), and (description). I am trying to make a NEW array with the values of the key "title" from each dictionary in that first array. Let me explain WHY I am doing this and maybe that will provide a better all around explanation. I am trying to let people pick from a pre-determined list. Heck, if this was a web page it would be very simple since all I really care about are the "points" and the "Title". On a web site I could simply do a drop down combo-box with the "points" being the value and the title being the text for each row. But this is not a web page. So what I am trying to do here is pop out a modal picker when they click the text field. The modal picker shows the alphabetical ordered "titles" from our new array. And whichever one they select, it closes the modal view and assigns that "title" text to the UITextField which cannot be edited by the user. I have some code to get my modal picker to pop out. But I need to feed it an array of just the "titles" of each dictionary in my real array. Thanks in advance (and yes I am a newbie)

• Manage more Images to move in View

  - by David Pollak

  hi everyone, I'm creating an app which has more UIImageView on a View, they should move normally from a side to the other. I have an issue: after entering the second image, the two UIImageView start to behave crazy (!) because they don' move freely, but they are like restricted in two different areas not touching each other even if I said different things the first thing that I want to do, is to let them move normally; this is the code I am using: `- (void)viewDidLoad { [super viewDidLoad]; pos = CGPointMake(14.0, 7.0); [NSTimer scheduledTimerWithTimeInterval:0.05 target:self selector:@selector(onTimer) userInfo:nil repeats:YES]; }` - (void) onTimer { pallone.center = CGPointMake(pallone.center.x+pos.x, pallone.center.y+pos.y); if(pallone.center.x > 320 || pallone.center.x < 0) pos.x = -pos.x; if(pallone.center.y > 480 || pallone.center.y < 0) pos.y = -pos.y; } and for the other image that has to enter after: - (IBAction)spara{ cos = CGPointMake(8.0, 4.0); [NSTimer scheduledTimerWithTimeInterval:0.05 target:self selector:@selector(inTimer) userInfo:nil repeats:YES]; } - (void)inTimer{ bomba.center = CGPointMake(bomba.center.x+pos.x, bomba.center.y+pos.y); if(bomba.center.x > 50 || bomba.center.x < 0) pos.x = -pos.x; if(bomba.center.y > 480 || bomba.center.y < 0) pos.y = -pos.y; } what should I change ? and if I'd like the images to move only in one way (y) ? how do I do this ? I know, I'm a newbie thanks in advance

• Obj-C Sending Messages Between Classes

  - by user544359

  I'm a newbie in iPhone Programming. I'm trying to send a message from one view controller to another. The idea is that viewControllerA takes information from the user and sends it to viewControllerB. viewControllerB is then supposed to display the information in a label. viewControllerA.h #import <UIKit/UIKit.h> @interface viewControllerA : UIViewController { int num; } -(IBAction)do; @end viewControllerA.m #import "viewControllerA.h" #import "viewControllerB.h" @implementation viewControllerA - (IBAction)do { //initializing int for example num = 2; viewControllerB *viewB = [[viewControllerB alloc] init]; [viewB display:num]; [viewB release]; //viewA is presented as a ModalViewController, so it dismisses itself to return to the //original view, i know it is not efficient [self dismissModalViewControllerAnimated:YES]; } - (void)dealloc { [super dealloc]; } @end viewControllerB.h #import <UIKit/UIKit.h> @interface viewControllerB : UIViewController { IBOutlet UILabel *label; } - (IBAction)openA; - (void)display:(NSInteger)myNum; @end viewControllerB.m #import "viewControllerB.h" #import "viewControllerA.h" @implementation viewControllerB - (IBAction)openA { //presents viewControllerA when a button is pressed viewControllerA *viewA = [[viewControllerA alloc] init]; [self presentModalViewController:viewA animated:YES]; } - (void)display:(NSInteger)myNum { NSLog(@"YES"); [label setText:[NSString stringWithFormat:@"%d", myNum]]; } @end YES is logged successfully, but the label's text does not change. I have made sure that all of my connections in Interface Builder are correct, in fact there are other (IBAction) methods in my program that change the text of this very label, and all of those other methods work perfectly... Any ideas, guys? You don't need to give me a full solution, any bits of information will help. Thanks.

• NSMagedObjectContext, threads and NSFechedResultsController

  - by tmpz

  Dear iphone developers, Core Data newbie speaking here. In my application I have two NSManagedObjectContext that refer to that same NSPersistentStorageController. One ManagedObjectContext (c1) is in the main thread --created when I create a NSFetchedResultsController -- and the second ManagedObjectContext (c2) created in a second thread, running in the background, detached from the main thread. In the background thread I pull some data off a website and insert the entities created for the pulled data in the thread's ManagedObjectContext (c2). In the meanwhile, the main thread sits doing nothing and displaying a UITableView whose data do be display should be provided by the NSFetchedResultsController. When the background thread has finished pulling the data and inserting entities in c2, c2 saves, and the background thread notifies the main thread that the processing has finished before it exiting. As a matter of fact, the entities that I have inserted in c2 are know by c1 because it can ask it about one particular entity with [c1 existingObjectWithID:ObjectID error:&error]; I would expect at this point, if I call on my tableview reloadData to see some rows showing up with the data I pulled from the web in the background thread thanks to the NSFetchedResults controller which should react to the modifications of its ManagedObjectContext (c1). But nothing is happening! Only if I restart the application I see what I have previously pulled from the web! Where am I doing things wrong? Thank you in advance!

• two view controllers and reusability with delegate

  - by netcharmer

  Newbie question about design patterns in objC. I'm writing a functionality for my iphone app which I plan to use in other apps too. The functionality is written over two classes - Viewcontroller1 and Viewcontroller2. Viewcontroller1 is the root view of a navigation controller and it can push Viewcontroller2. Rest of the app will use only ViewController1 and will never access Viewcontroller2 directly. However, triggered by user events, Viewcontroller2 has to send a message to the rest of the app. My question is what is the best way of achieving it? Currently, I use two level of delegation to send the message out from Viewcontroller2. First send it to Viewcontroller1 and then let Viewcontroller1 send it to rest of the app or the application delegate. So my code looks like - //Viewcontroller1.h @protocol bellDelegate -(int)bellRang:(int)size; @end @interface Viewcontroller1 : UITableViewController <dummydelegate> { id <bellDelegate> delegate; @end //Viewcontroller1.m @implementation Viewcontroller1 -(void)viewDidLoad { //some stuff here Viewcontroller2 *vc2 = [[Viewcontroller2 alloc] init]; vc2.delegate = self; [self.navigationController pushViewController:vc2 animated:YES]; } -(int)dummyBell:(int)size { return([self.delegate bellRang:size]); } //Viewcontroller2.h @protocol dummyDelegate -(int)dummyBell:(int)size; @end @interface Viewcontroller2 : UITableViewController { id <dummyDelegate> delegate; @end //Viewcontroller2.m @implementation Viewcontroller2 -(int)eventFoo:(int)size { rval = [self.delegate dummyBell:size]; } @end

• The binary you uploaded was invalid. A pre-release beta version of the SDK was used to build the app

  - by Nick

  I am having a problem submitting my new app to the appstore. ItunesConnect gives me the error: The binary you uploaded was invalid. A pre-release beta version of the SDK was used to build the application. I haven't changed anything, I can compile to a ad-hoc certificate and that works fine. I uploaded another app yesterday and that worked fine too. All the targets and project info is set to compile to the base SDK iPhone OS 3.0. I even upgraded to the latest SDK but same result. Any ideas?

• A valid provisioning profile for this executable was not found

  - by munchine

  I'm trying to debug my first app on the device and got this error message, A valid provisioning profile for this executable was not found. I've gone thru the Apple manuals, checked SO and other sites but cannot work out what I've done wrong? This is what I've done so far. Got my provisioning profile. I check Organizer and it's there, plus it shows that it is installed on my iPhone (green button). My profile is in ~/library/MobileDevice/Provisioning Profiles My certificate is in Keychain Access In Xcode I have have the Project Info showing the Entitlements correctly. The Code Signing Identity matches what's in Keychain. I've set the Target Info to be the same as Project Info. Have I done something inconsistently?

• Fix keyboard orientation in landscape iPad app (upside down keyboard)

  - by hjd

  I'm converting a landscape (UIInterfaceOrientationLandscapeRight) iPhone app to be a universal app. So far I've got the orientation working properly: the iPad version will launch with the right splash graphic and start in the right orientation (LandscapeLeft or LandscapeRight) depending on how the user is holding it. But: when I trigger the keyboard while the iPad is in LandscapeLeft, the keyboard appears upside down: I can't post images yet so you can see the error here: http://blog.durdle.com/images/ipad_keyboard.png That's a UIAlertView with a UITextField added to it. I guess the keyboard at this point is in the LandscapeRight orientation. If I rotate the device to LandscapeRight, the game view rotates to match the keyboard, then if I rotate the device back to LandscapeLeft the entire interface - game AND keyboard rotate together to appear correctly. So: how do I ensure it appears in the correct orientation?

• Hide/ change width/ change position of UIButton based on device type

  - by Giles Van Gruisen

  I'm using the new in-app SMS features in my iPhone app, but obviously iPod Touches aren't able to send and receive SMS without support of a third party app. I know all well how to detect the device and how to hide a UIButton, but what I do not know is how to change the width of the others. Above are the three icons. The one on the far rights needs to be hidden on an iPod Touch, and the other two need to adjust size/ position to fill the remaining space. Any tips on programatically changing the position and width of a UIButton is greatly appreciated. Thanks!

• "Upgrade current target for ipad" is grayed out (disabled)?

  - by Eric

  I'm trying to create a universal iPhone/iPad app using this method: http://www.enscand.com/roller/enscand/entry/ready_for_ipad which is also described all over the web. My problem is that the "Upgrade current target for iPad" line is grayed out and doesn't appear at all when I right click the target. I'm working on an app that I inherited from someone, and have tried this with an app that I wrote entirely myself (no problems on that one). And yes, I'm sure that I'm selecting the target. Just wondering if anyone has any insight into what checks are being run that would cause this option to be unavailable.

• Managing subviews in Cocoa Touch

  - by brainfsck

  Hi, I'm developing an iPhone app. I need to create a Quiz application that has different Question views embedded in it (see my similar question). Different types of Question will have different behavior, so I plan to create a controller class for each type of Question. The MultipleChoiceQuestionController would set up a question and 3-4 buttons for the user to select an answer. Similarly, the IdentifyPictureQuestionController would load an image and present a text box to the user. However, the docs say that a UIViewController should only be used for views that take up the entire application window. How else can I create a class to manage events in my subviews? Thanks,

• UITextView adding text to new line

  - by Subro

  I would like to add new lines of text to my UITextView for my iPhone app. Basically my textview starts with a single line, and as app advances, new lines are added. However I can add only to the end or beginning of the existing text. How can I make such an entry into a new line. Can I manually send \n to the textview.text at a calculated range/location. E.g. of what I mean. line 1: This is first line of text. This is second line 2: line of text. --- I want: line 1: This is first line of text. line 2: This is second line of text. Thanks!

• Extremely strange iTunesConnect error--Missing Screenshot??

  - by Steve

  So I finally got through the mess of preparing my app binary to support the iPad, making it a univeral app, and then I got this strange error "Missing Screenshot". And due to the fact that I hadn't uploaded my iPad screenshots to the original binary (I forgot) that error made sense. So I went into the original iPhone app, added my iPad screenshots, and hoped that somehow it would just work, but it didn't. So then, I rejected the binary, and made sure the iPad screenshots were where they needed to be, re-uploaded a new binary, and it still says MISSING SCREENSHOT. I emailed apple, and they characteristically won't get back to me till probably sometime next week, so I am hoping that someone here can shed some on this error for me! What can I do to get that error to go away, so I can get my ap reviewed and updated? Thank you very much!

• self.view.frame.size in viewDidLoad and didRotateFromInterfaceOrientation are different

  - by tokentoken

  I created iphone view-based project, and added UINavigationController by code. - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { TestViewController *vc = [[TestViewController alloc]init]; navController = [[UINavigationController alloc]initWithRootViewController:vc]; [window addSubview:navController.view]; [window makeKeyAndVisible]; return YES; } After that, I checked self.view.frame.size.height in viewDidLoad and didRotateFromInterfaceOrientation, and they're different. (they're 460 and 416) I suppose the height of NavigationBar is not included in viewDidLoad, but should I add it manually (add 44)?

• Initializing links in jqtouch in AJAX loaded content

  - by Cody Caughlan

  I have an iphone web app built in jqtouch, when content is loaded by links ("a" tags) then any content on the next page is parsed by jqtouch and any links are initialized. However, when I load content via an AJAX call and append() it to an element then any links in that content are NOT initialized by jqtouch. Thus any clicks on those links are full-blown clicks to a new resource and are not handled by jqtouch, so at that point you've effectively broken out of jqtouch. My AJAX code is: #data <script type="text/javascript"> $.ajax({ url: '/mobile/nearby-accounts', type: 'GET', dataType: 'html', data: {lat: lat, lng: lng}, success: function(html) { $('#data').empty().append(html); // Is there some method I call on jqtouch to have any links in $('#data') be hooked up to the jqtouch lifecycle? } </script> Thanks in advance.

• UITableView backgroundColor always gray on iPad

  - by rjobidon

  Hi, When I set the backgroundColor for my UITableView it works fine on iPhone (device and simulator) but NOT on the iPad simulator. Instead I get a light gray background for any color I set including groupTableViewBackgroundColor. Steps to reproduce: Create a new navigation-based project. Open RootViewController.xib and set the table view style to "Grouped". Add this responder to the RootViewController:- (void)viewDidLoad { [super viewDidLoad]; self.view.backgroundColor = [UIColor blackColor]; } Select Simulator SDK 3.2, build and run. You will get a black background (device and simulator). Select your target in the project tree. Click on Project : Upgrade Current Target for iPad. Build and run. You will get a light gray background. Revert the table view style to Plain and you will get a black background. Thanks for your help!

• Objective C defining UIColor constants

  - by futureelite7

  Hi, I have a iPhone application with a few custom-defined colors for my theme. Since these colors will be fixed for my UI, I would like to define the colors in a class to be included (Constants.h and Constants.m). How do I do that? (Simply defining them does not work because UIColors are mutable, and would cause errors - Initalizer not constant). /* Constants.h */ extern UIColor *test; /* Constants.m */ UIColor *test = [UIColor colorWithRed:1.0 green:1.0 blue:1.0 alpha:1.0]; Thanks!

• Is Objective C fast enough for DSP/audio programming

  - by morgancodes

  I've been making some progress with audio programming for iPhone. Now I'm doing some performance tuning, trying to see if I can squeeze more out of this little machine. Running Shark, I see that a significant part of my cpu power (16%) is getting eaten up by objc_msgSend. I understand I can speed this up somewhat by storing pointers to functions (IMP) rather than calling them using [object message] notation. But if I'm going to go through all this trouble, I wonder if I might just be better off using C++. Any thoughts on this?

• user disallowed geolocation - notify user second time

  When trying to get geolocation on iPhone the first time - I declined. Every other time I want to get the location (before another reload of the page) I get no response (no error and no success): navigator.geolocation.getCurrentPosition( function (location) { ig_location.lat = location.coords.latitude; ig_location.lng = location.coords.longitude; alert('got it!'); }, function(PositionError) { alert('failed!' + PositionError.message); } ); Is there a way to notify the user every time I fail to get the location? (I do not need to use watchPosition...)

• Reading a plist utf-8 value as utf-16

  - by ennuikiller

  I'm working on an iphone app that needs to display superscripts and subscripts. I'm using a picker to read in data from a plist but the unicode values aren't being displayed corretly in the pickerview. Subscripts and superscripts are not being recognized. I'm assuming this is due to the encoding of the plist as utf-8, so the question is how do a convert a plist string encoding from utf-8 to utf-16 ? Just a little more elaboration: If I do this it displays properly at least in a textfield: NSString *equation = @"x\u00B2 + y\u00B2 = z\u00B2" However if I define the same string in a plist and try to read it in and assign it to a string and display it on a pickerview it just displays the the encoding and not the superscripts. @Matt: thanks for your suggestion the unicode is being escaped that is \u00B2 = \u00B2. Googling for "escaped values in plists" returned no useful results, and I haven't been able to use the keyboard cmd-ctrl-shift-+ to work. Any further suggestions would be greatly appreciated!!
