  • 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?

  • Extract part of HTML in C/Objective-C

    - by Dan
    Hi, I need to extract the detail content of a website while preserve all formatting of the division. The section I wish to extract is: ... <div class="detailContent"><p> <P dir=ltr><STRONG>Hinweis</strong>: Auf ... </p> </div> ... My current solution is to use HTMLParser from libxml2 and xpath to find the nodes and walk through all the nodes to reconstruct this piece of HTML. This is a long an complicated code. I' just wondering if there is an easier solution to extract part of HTML? Thanks.

  • How can I remove the present view when I have added more than one subView ?

    - by srikanth rongali
    How can I remove the present view when I touched the close button. I did [self.view removeFromSuperView] when I added only one subView. It worked. But, I have now added another subView to the previous subView. I need to to get the parent view . How can I do it. My code of adding the subView is here. When I did the following only one view is removed. //FirstViewController: UIViewController -(void)libraryFunction:(id)sender { LibraryController *libraryController = [[LibraryController alloc]init]; [self.view addSubview:libraryController.view]; } //LibraryController: UIViewController -(void)viewDidLoad{ RootViewController *rootViewController = [[RootViewController alloc] initWithStyle:UITableViewStylePlain]; UINavigationController *aNavigationController = [[UINavigationController alloc] initWithRootViewController:rootViewController]; self.navController = aNavigationController; [aNavigationController release]; [rootViewController release]; [self.view addSubview:navController.view]; } //RootViewController: UITableViewController - (void)viewDidLoad { [super viewDidLoad]; self.navigationItem.rightBarButtonItem = [[UIBarButtonItem alloc] initWithTitle:@"Close" style:UIBarButtonItemStyleBordered target:self action:@selector(close:)]; } -(void)close:(id)sender { [self.view removeFromSuperview]; } Thank You.

  • 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.

  • Tab-Bar not hiding on all views

    - by Sheehan Alam
    I have a tab-bar controller that loads a RootView. The RootView has 4 buttons that will load a UITableView I don't want my tab-bar to be visible in the RootView so I added the following code: -(void)viewDidLoad{ self.hidesBottomBarWhenPushed = YES; } When I initially load the app the tab-bar doesn't appear, but when I click on a button, and go back to the RootView the tab-bar still appears. I have tried placing this code in viewWillAppear and other application lifecycle methods but no luck.

  • How to animate a UIButton selected background Image

    - by Thomas Joos
    hi all, I have a class defining a custom UIButton. I configurate a normal and selected state like this: //custom image UIImage *image = [UIImage imageNamed:@"customIconCreationBG.png"]; UIImage *stretchImage = [image stretchableImageWithLeftCapWidth:0.0 topCapHeight:0.0]; [self setBackgroundImage:stretchImage forState:UIControlStateNormal]; UIImage *imageSelected = [UIImage imageNamed:@"customIconCreationBG_selected.png"]; UIImage *stretchImageSelected = [imageSelected stretchableImageWithLeftCapWidth:0.0 topCapHeight:0.0]; [self setBackgroundImage:stretchImageSelected forState:UIControlStateSelected]; In another class I'm filling an array with custom buttons and i'm adding a button pressed method. It sets the selected state to TRUE -(void)buttnPressed:(id)sender { NSLog(@"button pressed"); [[NSNotificationCenter defaultCenter] postNotificationName:@"unselectBGIcons" object:self]; HorizontalListIcon *pressedIcon = ((HorizontalListIcon *)sender); [pressedIcon setSelected:TRUE]; } The button switches to another background, which is great. Is there a way to animate this change ( fading in? ) because it's a bit hard now. Greets

  • How do I change the UIView programmatically?

    - by user317834
    I have created View A and View B. My window has View A displayed on the screen. I also have a UIButton on View A. I want to switch from View A to View B when I click on the Button. I am not using any UIViewController. Is it possible to switch the views without using controller? I am calling buttonAction method on TOUCHUPINSIDE The problem is that it doesn't do anything when I say [ViewA removeFromSuperView]; What should I do now?

  • Properly releasing UITableViewController and UITableView directly added to a UIViewController

    - by JK
    I have a UIViewController (parentVC) to which I add a UITableViewController as follows (it is not pushed since the tableview only occupies about half the screen): tableVC = [[SmallTableVC alloc] initWithStyle:UITableViewStylePlain]; [self.view addSubview:tableVC.tableView]; In dealloc, I add [tableVC release]; Using instruments, I can see that the tableVC is indeed fully released when parentVC released, which is good, but I am not sure why as I thought that the UITableView of tableVC would have a retain count of 2 (1 for retention by tableVC and 1 for retention by parentVC). My intuition was that an additional [tableVC.tableView release] would be required, but adding it crashes the app. Why is tableVC released properly by the current code (if indeed it actually is)? Does a UITableViewController not retain its tableView? Thanks.

  • How to animate stuff when using -drawRect: ?

    - by mystify
    I didn't use subviews but painted my things with -drawRect: inside an UIView subclass. Now I want to do some animations in there. I guess that I can't count on core animation now since I have no subviews. So how would I animate then? Would I set up a timer which fires like 30 times per second? How would I know the animation step? Would I make an ivar which counts the frame of the animation so that I can do my stuff in -drawRect as it gets called?

  • How can I build an app with multiple types of controllers?

    - by Sheehan Alam
    How can I accomplish the following: When my app loads a UIView will show 4 buttons Clicking on a button will load a UITabBarController (not a UIView with a UITabBar) that can display multiple views. This seems challenging to me, because in order for me to use the UITabBarController I need to add this to the window's subview in my appDelegate. By doing so, my app automatically will load with the UITabbarController in the root view.

    - by user337174
    I am using two UIAction sheets within my current project. I can get one to work perfectly fine but when i insert a second action sheet it runs the same arguements as the first. How do i define the actionsheets seperatly? -(IBAction) phoneButtonClicked:(id)sender { // open a dialog with just an OK button UIActionSheet *actionSheet = [[UIActionSheet alloc] initWithTitle:nil delegate:self cancelButtonTitle:@"Cancel" destructiveButtonTitle:nil otherButtonTitles:[NSString stringWithFormat:@"Phone: %@",phone],nil]; actionSheet.actionSheetStyle = UIActionSheetStyleDefault; [actionSheet showInView:self.view]; // show from our table view (pops up in the middle of the table) [actionSheet release]; } -(IBAction) mapButtonClicked:(id)sender { // open a dialog with just an OK button UIActionSheet *mapActionSheet = [[UIActionSheet alloc] initWithTitle:nil delegate:self cancelButtonTitle:@"Cancel" destructiveButtonTitle:nil otherButtonTitles:[NSString stringWithFormat:@"Map"],nil]; mapActionSheet.actionSheetStyle = UIActionSheetStyleDefault; [mapActionSheet showInView:self.view]; // show from our table view (pops up in the middle of the table) [mapActionSheet release]; } -(void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex { if(buttonIndex == 0){ NSString *callPhone = [NSString stringWithFormat:@"tel:%@",phone]; NSLog(@"Calling: %@", callPhone); [[UIApplication sharedApplication] openURL:[NSURL URLWithString:callPhone]]; } }

  • Very very weird problem with UIImageView property - I can access it then I can't, and it's not nil.

    - by just_another_coder
    Very very weird problem with UIImageView property on iPad application @interface MyViewController : UIViewController { IBOutlet UIImageView* coverImage; } @property(nonatomic, retain) IBOutlet UIImageView* coverImage; … more code @implementation MyViewController @synthesize coverImage; … more code - (void)viewDidLoad { [super viewDidLoad]; NSString* imageName = @"my_image.png"; UIImage* tempImage = [UIImage imageNamed:imageName]; [self.coverImage setImage:tempImage]; } The above code WILL display the image. In another part of code: -(IBAction) stopButtonPressed:(id)sender { [self.coverImage setHidden:YES]; NSLog(@"coverImage desc: %@", [coverImage description]); } The image will NOT disappear. I know the reference to the image isn't nil, because it gives me this output: 2010-05-29 17:37:40.706 MyApp[95360:207] coverImage desc: UIImageView: 0x5128420; frame = (0 0; 1024 768); autoresize = RM+BM; userInteractionEnabled = NO; layer = CALayer: 0x512bed0 In addition, if I move the code in viewDidLoad to another part of the class, and try to execute it from there, it fails to show the image at all.

  • How to specify number of headers in section UITableView.

    - by Mr. McPepperNuts
    if ([tempArray containsObject: [sectionInfo indexTitle]]) { return nil; }else { [tempArray addObject: [sectionInfo indexTitle]]; return [sectionInfo indexTitle]; } return [sectionInfo indexTitle]; The code above groups the cells in alphabetical order but displays a blank header instead of the appropriate title. Could this possibly be because I did not specify the number of headers? This would naturally be a single header for every letter in the alphabet.

    - by iphoneDev
    Hi, I want to mix audio files of different size into a one single .wav file. There is a sample through which we can mix files of same size [(http://www.modejong.com/iOS/#ex4 )(Example 4)]. I modified the code to get the mixed file as a .wav file. But I am not able to understand that how to modify this code for unequal sized files. If someone can help me out with some code snippet,i'll be really thankful.
