  • How do I convert a NSString into TIS-620 encoded string

    - by MacPC
    In the apple document, I can see that there's a way to convert from UTF8 string to ASCII string like this NSData *asciiData = [theString dataUsingEncoding:NSASCIIStringEncoding allowLossyConversion:YES]; NSString *asciiString = [[NSString alloc] initWithData:asciiData encoding:NSASCIIStringEncoding]; But my app requires a TIS-620 string to post to a site so I try to do the same thing NSData *asciiData = [newPost.header dataUsingEncoding:kCFStringEncodingMacThai allowLossyConversion:YES]; NSString *asciiString = [[NSString alloc] initWithData:asciiData encoding:kCFStringEncodingMacThai]; NSLog(@"%@", asciiString); The output I got is like this ???????????. Does anyone know how to convert the NSString to TIS-620 properly? Thanks so much.

  • Resizing UIView to match its content

    - by Thody
    I have a UITextField, a UIButton, and a UIWebView nested in a UIView, which is nested in a UIScrollView. After the UIWebView has loaded its content, I need it to resize the UIWebView and UIView so that the UIScrollView will scroll. I currently have the UIScrollView getting its contentSize from the UIView, but I can't figure out how to do the resizing after the UIWebView's content has loaded.

  • How can I detect if a string contains punctuation marks at the end?

    - by Sheehan Alam
    Lets assume I have the string: "Hello I like your shoes #today...!" I am tokenizing the string by spaces: return [string componentsSeparatedByString:@" "]; So my array contains: Hello I like your shoes #today...! I want to focus on "#today...!" any word that has a # in the prefix I am changing the font color. How can I make sure that only "#today" has its font color changed? I would basically like to figure out if a word has a punctuation mark at the end, and change the color for characters before the punctuation mark.

  • http authenitcation in xcode

    - by user313100
    I am trying to make twitter work in my app and everything works fine except the code does not seem to recognize an error from twitter. If the username/password are not valid, I get an error message through this function: - (void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data { NSString* strData = [[[NSString alloc] initWithBytes:[data bytes] length:[data length] encoding:NSASCIIStringEncoding] autorelease]; NSLog(@"Received data: %@", strData ) ; return ; } It prints: Received data: Could not authenticate you. . However, the app continues to the post a tweet view I have and ignores the error. Obviously, I do not have something setup right to detect such an error from twitter so my question is how do I get xcode to recognize an error like this? This uses basic http auth btw and don't mention anything about OAuth...just trying to get this to work for now.

  • Adding Colours (Colors) Together like Paint (Blue + Yellow = Green, etc)

    - by glenstorey
    I'm making an iOS game using cocos2d libraries. Lets say you have two objects that have two separate colours - defined in RGB as Blue: 0,0,255 Yellow: 255,255,0 I want to add blue and yellow to make green. To over complicate things, let's say that the Blue object is bigger than the Yellow object (for the sake of argument let's say that the ratio is 2:1), I'm adding twice as much blue as yellow - how to I calculate this new (light green) colour correctly. I understand LAB * Color Space is useful for this sort of 'natural colour' kind of thing, but I'm not sure how to use it - especially in the context of a cocos2d object which (AFAIK) is limited to using RGB in its colour schemes. I'd really appreciate practical help on how to implement this. Thanks heaps!

  • Tab bar application with UINavigation Controller MOC not being retained.

    - by iamsmug
    I created a tab bar application from the template and added a navigation controller to one of the tabs. I have already created this app from the navigation app template already and is working. The reason I am doing it this way is because I need to add a tab bar and thought it would be easier starting by using the tab bar project template and adding the nav controller to it rather than the other way round. I have copied the data model over from the other project and added the relevant code to where it should be. The problem I am having is passing the moc from the app delegate to the tab with the nav controller on. Here is a snippet from my applicationDidFinishLaunching method in my app delegate: - (void)applicationDidFinishLaunching:(UIApplication *)application { [self createEditableCopyOfDatabaseIfNeeded]; Top_BananaTableViewController *top_BananaTableViewController = (Top_BananaTableViewController *)[navigationController topViewController]; top_BananaTableViewController.managedObjectContext = self.managedObjectContext; // Add the tab bar controller's current view as a subview of the window [window addSubview:tabBarController.view]; [window makeKeyAndVisible]; } Everything seems fine here but when it comes to the fetchedResultsController on my nav controller view it bombs out with: '+entityForName: could not locate an NSManagedObjectModel for entity name 'cards'' When I checked what was set to my managedObjectContext on that view it was null. I don't know why or where it is loosing it's setting. Please help.

  • Download data in background with iOS4

    - by Sagar
    As per the latest update of Kindle V2.5, it has support of "continue downloading books while the app is in the background on iOS 4 devices". How is it possible to download content in background? As per the iOS multitasking documentation, only audio, voip & location updates are possible in background. And I've also maken sure that NSURLConnection doesn't download new data work while app goes background. Then how's it possible with Kindle app? Edit: I haven't checked Kindle App in iOS4 multitasking enabled device. So if anyone let me (& community) know what exactly Kindle app does to download, that would be very much helpful.

  • Custom cell and Delete/Move indicators

    - by Kamchatka
    Hello, I have a custom UITableViewCell. However, when I got in edit mode, I don't have any Delete and Move indicators appearing. The custom cell draws itself in the contentView. In layoutSubviews, I make sure there is space on the left and one the right of the contentView so that the controls can appear (if this was the problem). - (void)layoutSubviews { self.contentView.frame = CGRectMake(50, 0, self.frame.size.width - 100, sub.thumbnail.size.height + 20); } In the UITableViewController, I return YES in: - (BOOL)tableView:(UITableView *)tableView canMoveRowAtIndexPath:(NSIndexPath *)indexPath { How could I solve this lack of interactivity. Is there something specific for custom cells? Thanks!

  • Isuue when uploading new version to app store

    - by user2978997
    Can I use new certificate and provisioning profile to upload new version? We have discovered one or more issues with your recent delivery for "EMTV News". To process your delivery, the following issues must be corrected: Invalid Provisioning Profile - The provisioning profile included in the bundle com.pointabout.C1E322F0 (Payload/EMTV.app) is invalid. (Missing code-signing certificate.) For more information, visit the iOS Developer Portal. Once these issues have been corrected, go to the Version Details page and click "Ready to Upload Binary." Continue through the submission process until the app status is "Waiting for Upload." You can then deliver the corrected binary. Regards, The App Store team Note: I am using new Certificate and provisioning profile but same bundle ID which is being used in old version of the app.

  • How to create a formatted localized string?

    - by mystify
    I have a localized string which needs to take a few variables. However, in localization it is important that the order of the variables can change from language to language. So this is not a good idea: NSString *text = NSLocalizedString(@"My birthday is at %@ %@ in %@", nil); In some languages some words come before others, while in others it's reverse. I lack of an good example at the moment. How would I provide NAMED variables in a formatted string? Is there any way to do it without some heavy self-made string replacements? Even some numbered variables like {%@1}, {%@2}, and so on would be sufficient... is there a solution?

  • Localizing other pages in Settings.bundle

    - by joneswah
    I have other pages within my app preferences which are stored as separate files within the settings.bundle. It has come time to localize my app and I can only seem to get the Root values to localize. I was wondering whether there was a trick? The following image shows that my second screen is stored within a file called "MyPrefs.plist" and I have created a corresponding named file "MyPrefs.strings" in the en.lproj directory. Mirroring the same naming and location as the Root.plist and Root.strings. The values with the Root.plist are converted as expected but not in the extra screen. Is there any trick to localizing secondary screens with the settings.bundle?

  • MPMoviePlayerContentPreloadDidFinishNotification seems more reliable than MPMoviePlayerLoadStateDidChangeNotification

    - by user567889
    I am streaming small movies (1-3MB) off my website into my app. I have a slicehost webserver, I think it's a "500MB slice". Not sure off the top of my head how this translates to bandwidth, but I can figure that out later. My experience with MPMoviePlayerLoadStateDidChangeNotification is not very good. I get much more reliable results with the old MPMoviePlayerContentPreloadDidFinishNotification If I get a MPMoviePlayerContentPreloadDidFinishNotification, the movie will play without stuttering, but if I use MPMoviePlayerLoadStateDidChangeNotification, the movie frequently stalls. I'm not sure which load state to check for: enum { MPMovieLoadStateUnknown = 0, MPMovieLoadStatePlayable = 1 << 0, MPMovieLoadStatePlaythroughOK = 1 << 1, MPMovieLoadStateStalled = 1 << 2, }; MPMovieLoadStatePlaythroughOK seems to be what I want (based on the description in the documentation): MPMovieLoadStatePlaythroughOK Enough data has been buffered for playback to continue uninterrupted. Available in iOS 3.2 and later. but that load state NEVER gets set to this in my app. Am I missing something? Is there a better way to do this?

  • How to push text from one UITextfield to another UITextfield in the next View? And back!?

    - by Chrizzz
    an Hi, I have an UITextField in one view, UITextField A in View A. And I have another in view B, UITextField B in View B. I use a Navigation Controller Bar to switch between the views. The UITextFields are properties and connected Outlets of both views A and B. On my view A there is an "Options"-button which pushes view B. So when you are typing in Textfield A, I would like the same text to appear in Textfield B. When you edit TextField B and you go back to view A (via the "Title View A"-button in de navigation bar), I would like the same text to re-appear in Textfield A. I expected this to be easy. But I can't get it working. I tried: ViewBController *controller = [[ViewBController alloc] initWithNibName:@"ViewBController" bundle:nil]; controller.TextFieldA.text = TextFieldB.text But nothing appeared in view B. And how do I get back? I dont want to use NSUserdefaults because I would have to remove the values also.

  • NSArray containObjects method

    - by Anthony Chan
    Hi, I have a simple question regarding xcode coding but don't know why things are not performing as I think. I have an array of objects (custom objects). I just want to check if this one is within the array. I used the following code: NSArray *collection = [[NSArray alloc] initWithObjects:A, B, C, nil]; //custom "Item" objects Item *tempItem = [[Fruit alloc] initWithLength:1 width:2 height:3]; //3 instance variables in "Item" objects if([collection containsObject:tempItem]) { NSLog(@"collection contains this item"); } I suppose the above checking will give me a positive result but it's not. Further, I checked whether the objects created are the same. NSLog(@"L:%i W:%i H:%i", itemToCheck.length, itemToCheck.width, itemToCheck.height); for (int i = 0, i < [collection count], i++) { Item *itemInArray = [collection objectAtIndex:i]; NSLog(@"collection contains L:%i W:%i H:%i", itemInArray.length, itemInArray.width, itemInArrayheight); } In the console, this is what I got: L:1 W:2 H:3 collection contains L:0 W:0 H:0 collection contains L:1 W:2 H:3 collection contains L:6 W:8 H:2 Obviously the tempItem is inside the collection array but nothing shows up when I use containsObject: to check it. Could anyone give me some direction which part I am wrong? Thanks a lot!

  • How do Apple code level support requests work?

    - by JustinXXVII
    I'm having an issue with a build that I can't figure out, and I'm considering filing a support request. It says I'll get contacted in about 3 days usually. Can anyone explain the process this takes, because I don't want to burn one of these by screwing up! Should I include a zip file of my entire project, or will the source file I'm having issues with be enough? Do I have to be at my computer when they contact me? Thanks for your help, generous ones!

  • Switching between TabBarController Views when event fired

    - by aahrens
    I have a UITabBarController with two different views to switch between. What I would like to do is when a button is clicked in View1 to switch directly to View2. Then in View2 if they click a button it switches them to View1. It transfers between View1 and View2 when the click on the tabBarController fine but I'm trying to perform the switching for them when an event occurs Is there a way to do this by calling a method on my UITabBarController? @interface CalcAppDelegate : NSObject <UIApplicationDelegate> { UITabBarController *tabBarController; }
