  • Reload UItabbar view when using selectedIndex

    - by Hetal Vora
    Hi, In my application I have 4 tabs in my tab bar. There is a navigation where if i click on a button on tab bar 2 view, it should take me to tab bar 3 view. I am doing this by using setting the selectedIndex property of tab bar like appDelegate.tabBarController.selectedIndex = 2; However, this doesn't reload the view of tab bar 3. It simply shows the tab bar 3 view that was last accessed (which may be down the navigation hieararchy in tab bar 3). Please help as to how can i reload the root view of tab bar 3. I tried having the delegate method of tabbar as below: - (void)tabBarController:(UITabBarController *)tabBarController didSelectViewController:(UIViewController *)viewController { [viewController.navigationController popToRootViewControllerAnimated:FALSE]; } but this works only if I click on a tab to go to the view and doesn't work with selectedIndex.Please help.

  • UItabBarItem highlight state image

    - by Paul Solomon
    I'd like to be able to change the highlighted state image on an UITabBarItem when it is selected? Is it possible to subclass and access this? or do I need to roll my own navigation code? - start edit I didn't articulate what I was looking for earlier. I am looking for the semi-transparent white overlay reference that the device adds to the selected state/image of the UITabBar. See image! http://solomon71.com/images/UITabBarItem.png

  • How to crop the UIImage?

    - by Rajendra Bhole
    Hi, I develop an application in which i process the image using its pixels but in that image processing it takes a lot of time. Therefore i want to crop UIImage (Only middle part of image i.e. removing/croping bordered part of image).I have the develop code are, - (NSInteger) processImage1: (UIImage*) image { CGFloat width = image.size.width; CGFloat height = image.size.height; struct pixel* pixels = (struct pixel*) calloc(1, image.size.width * image.size.height * sizeof(struct pixel)); if (pixels != nil) { // Create a new bitmap CGContextRef context = CGBitmapContextCreate( (void*) pixels, image.size.width, image.size.height, 8, image.size.width * 4, CGImageGetColorSpace(image.CGImage), kCGImageAlphaPremultipliedLast ); if (context != NULL) { // Draw the image in the bitmap CGContextDrawImage(context, CGRectMake(0.0f, 0.0f, image.size.width, image.size.height), image.CGImage); NSUInteger numberOfPixels = image.size.width * image.size.height; NSMutableArray *numberOfPixelsArray = [[[NSMutableArray alloc] initWithCapacity:numberOfPixelsArray] autorelease]; } How i take(croping outside bordered) the middle part of UIImage?????????

  • UINavigationBar height

    - by kpower
    In my app I work with an UINavigationController. I've added it to the window (MainWindow.xib, with IB) and simulated on my main view (in IB: Simulated User Elements / Top Bar / Navigation Bar). Navigation bar is displayed, but its height isn't standard. At least in IB it is bigger than in launched app. What's wrong? And how can I restore height to the initial state (as in IB)? P.S.: I know that I can set it directly from code. But this way looks like a "crutch".

  • Calculating File size before download - Downloading NSURLConnection Slider timing

    - by sagar
    Ok ! Coming to the point directly. What I want to do is explained as follows. I have an url of MP3 file. ( for example Sound File ) Now, When user starts application. Download should start & for that I have implemented following methods. -(void)viewDidLoad { [super viewDidLoad]; NSURL *url=[NSURL URLWithString:@"http://xyz.pqr.com/abc.mp3"]; NSURLRequest *req=[NSURLRequest requestWithURL:url cachePolicy:NSURLCacheStorageNotAllowed timeoutInterval:120]; NSURLConnection *con=[[NSURLConnection alloc] initWithRequest:req delegate:self startImmediately:YES]; if(con){ myWebData=[[NSMutableData data] retain]; } else { // [MainHandler performSelector:@selector(targetSelector:) withObject:nil]; } } -(void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response { NSLog(@"%@",@"connection established"); [myWebData setLength: 0]; } -(void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data { NSLog(@"%@",@"connection receiving data"); [myWebData appendData:data]; } -(void)connection:(NSURLConnection *)connection didFailWithError:(NSError *)error { NSLog(@"%@",@"connection failed"); [connection release]; // [AlertViewHandler showAlertWithErrorMessage:@"Sorry, there is no network connection. Please check your network and try again."]; // [self parserDidEndDocument:nil]; } -(void)connectionDidFinishLoading:(NSURLConnection *)connection { [connection release]; } Now, Above methods work perfectly for downloading. But missing points are as follows. I can not get the exact size which is going to be downloaded. ( means I want to know what is the size of file - which is going to be download )

  • Failed to set the initialPlaybackTime for a MPMoviePlayerController when recreating it in the second

    - by vicky
    Hi, everyone. It's really wired. When at the first time a MPMoviePlayerController (e.g., theMovie) is created, its initialPlaybackTime can be set successfully. But when theMoive is released and re-create a new MPMoviePlayerController, its intialPlaybackTime can not be set correctly, actually the movie always plays from the start. The code is as follows. -(void)initAndPlayMovie:(NSURL *)movieURL { MPMoviePlayerController *theMovie = [[MPMoviePlayerController alloc] initWithContentURL:movieURL]; // create a notification for moviePlaybackFinish [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(moviePlayBackDidFinish:) name:MPMoviePlayerPlaybackDidFinishNotification object:theMovie]; theMovie.initialPlaybackTime = 15; [theMovie setScalingMode:MPMovieScalingModeAspectFill]; [theMovie play];} -(void) moviePlayBackDidFinish:(NSNotification*)notification { MPMoviePlayerController * theMovie = [notification object]; [[NSNotificationCenter defaultCenter] removeObserver:self name:MPMoviePlayerPlaybackDidFinishNotification object:theMovie]; [theMovie release]; [self initAndPlayMovie:[self getMovieURL]]; } With the above code, when the viewcontroller did load and run initAndPlayMovie, the movie starts to play from 15 seconds, but when it plays finished or "Done" is pushed, a new theMovie is created and starts to play from 0 second. Does anybody know what happened with the initialPlaybackTime property of MPMoviePlayerController? And whenever you reload the viewController where the above code is (presentModalViewController from a parent viewcontroller), the movie can start from any playback time. I am really confused what's the difference of the MPMoviePlayerController registration methods between the viewcontroller load and the recreating it after release. Need your help! Thank you!

  • Can I center a UIToolbar item?

    - by Ben
    I am putting a label on a UIToolbar (per this tip: http://stackoverflow.com/questions/333441/adding-a-uilabel-to-a-uitoolbar). But the toolbar has a button on the left side, and so flexible spaces throw the label off the center, which is where I'd like it to be. Can I somehow center this toolbar item so that it remains centered in the toolbar? (Already tried balancing the button with a dummy fixed space, no dice.) Thanks!

  • iPad popover textfield - resignFirstResponder doesn't dismiss keyboard

    - by mosdev
    I have two text fields email and password. The following code works fine when the fields are presented on a regular view but when they are on a popover, the resignFirstResponder does not work (becomeFirstResponder works). textFieldsShouldReturn was called for both fields. Any idea if I am missing something? Thanks! - (BOOL)textFieldShouldReturn:(UITextField *)theTextField { if (theTextField == email) { [password becomeFirstResponder]; return NO; } [theTextField resignFirstResponder]; return NO; }

  • What causes this error? "CALayer position contains NaN: [240 nan]"

    - by Kevlar
    I've seen this happen whenever i rotate a screen that has a UITableView on it. I've found out that it happens inbetween the willRotate and didRotate method calls in UIViewController My co-workers have seen it in other spots as well, usually around rotation. It hadnt started happening until very recently, and we're stumped as to how we should deal with it (google searches don't turn up the error message in its exact form). Has anyone else encountered this that knows what to do about it?

  • Copying the bitmap contents of a UIView's context to that of another UIView

    - by Joonas Trussmann
    Basically what I want to do is copy the already rendered content (a PDF drawn into the UIView's graphics context using CGContextDrawPDFPage()) onto a similar UIView, without having to re render the PDF. The idea is, that I'd then be able to perform an animated transform on the UIView and later re render the PDF with more accuracy. For both UIViews I'm using a larger-than-screen CATiledLayer to make it easier to rerender the PDF once the user zooms in, if that makes any difference. Any tips? I'm kind of lost here.

  • "Instance variable 'xxx' accessed in class method....why?

    - by Michael Levy
    So please forgive me as I am very new to stackoverflow and to ios programming in general. I am attempting to change the text of a button i have, replacing current text with a date string (dateStringForInput) I am passing in from another class. The button is called myTodayButton and is declared in my .h file for my class inputMilesViewController... @property (strong, nonatomic) IBOutlet UIButton *myTodayButton; Below is the code from my .m. +(void) changeButtonText:(NSString*) dateStringForInput{ NSLog(@"we got to changebuttontext"); [_myTodayButton setTitle:dateStringForInput forState:UIControlStateNormal]; } I am getting the following error "Instance variable "_myTodayButton" accessed in class method. I understand that this is written in a class method rather than an instance method but i cant figure out how to get this change to happen. the button which prompts this call to changeButtonText is in the other class which is creating dateStringForInput. please help! thanks so much! be gentle with me....a bit overwhelmed . :-)

  • UISearchBar in a UITableView

    - by petert
    I'm trying to mimic the behaviour of a table view like one in the iPod app for Artists - it's a sectioned table view with a section index on the right and with a search bar at the top, but initially hidden when view shown. I am using sdk 3.1.2 and IB, so simply dragged a UISearchDisplayController in to my NIB - it does wire everything up ready for searching. The problem starts because I'm adding the UISearchBar in to the first section of the UITableView, because if I understand correctly I must do this so I can jump to the search bar by touching the search icon in the section index directly? When the table view appears I see the search bar but it has resized and I now have a white block behind the section index at the top. It does'nt take the color of the UISearchBar's surround which interestingly is different to that shown in Interface Builder. Searching around, I did find a tip to add a small navigation bar and a UISearchBar in a UIView, then add this to the table view cell - this works.. BUT the color of the navigation bar's background is what you'd expect normally (gray), not the different color as noted above?! More interesting, if I click the search bar to start a search, then click Cancel, all is fixed!!! The background along the whole tableview cell when the search bar is, is the same!!?! Thanks for any tips.
