  • Is it possible to create a UINavigationController within a ModalPopup?

    - by aloo
    Hi I have a modalViewController that I am popping up using [self presentModalViewController:myController animated:YES]; I have an event occurring within myController which I would like to result in another controller being pushed onto the navigation stack ON TOP OF myController (which again has been presented modally). How can I do this? I have tried the following from within myController: UINavigationController* navController = [[UINavigationController alloc] initWithRootViewController:self]; NewController* n = [[NewController alloc] init]; [navController pushViewController:n animated:YES]; [n release]; This does not work however....

  • Rapid taps on an OpenGL ES app introducing input delay

    - by Tim R.
    I am starting out writing a 2D game in OpenGL ES, and I have encountered an odd problem: if I rapidly tap the touchscreen, the input starts lagging behind the display. The more times I tap, the more delay it causes between the input and any indication of that input onscreen. It only happens if I intentionally tap very rapidly, but not from tapping and dragging with any number of fingers. What could be causing this? Excessive details follow: Both accelerometer input and taps are delayed by just tapping. The only events I am responding to are touchesBegan (below) in my EAGLView and accelerometer:(UIAccelerometer *)accelerometer didAccelerate:(UIAcceleration *)acceleration in my Game object. There doesn't seem to be any upper limit to the amount of delay: I've gotten up to 12 seconds of delay by tapping rapidly with five fingers. I have not seen any drops in framerate (it stays constantly at 60 fps) in the OpenGL ES tool in Instruments or by taking 1/the time between updates. Possibly relevant code: - (void) drawView:(id) sender { [game update:allTouches]; [renderer render:game]; } -(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event { allTouches = [event allTouches]; } allTouches is a pointer that gets passed to my Game every update, which passes it to each GameObject in their update methods.

  • Multiple View application and Navigation Bar

    - by byronh
    Hi. I'm working in a iphone view-based application. The application works this way: First view is a welcome view with buttons for load other views. Second view is a map that shows the location using gps. Third view is a search engine that loads some information to show on the map and on a list (This has two button to load map or table). Fourth view is a table view that shows the results and then loads the detail on another view and load a web site on another view. My problem is with this view, because i don't know how can implement a navigation bar in this view that loads the detail and the web view. Thanks for your help. Byron H.

  • How to delete a cell in UITableView by using custom button in cell ?

    - by srikanth rongali
    I have UITableView. I customized the cell height (increased). I have 4 labels(UILabel) and 1 image(UIImage) and 3 buttons (UIButton). one of the button is delete button. By touching the cell or button(play button) on the image a video is loaded and played. I need to delete the cell by touching delete button. If I touched the delete button the corresponding video is deleted from library . But, how to delete the cell and all remaining data in it ? I am not able to delete the cells or the data in the cells. How to do it ? I used these. But the control is not entering in to second method committedEditingStyle: - (BOOL)tableView:(UITableView *)tableView canEditRowAtIndexPath:(NSIndexPath *)indexPath { return YES; } - (void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath { if (editingStyle == UITableViewCellEditingStyleDelete) { } } Thank you. The following image shows the delete button of my program.

  • Sub-viewController doesn't get autorotation notifications, bug?

    - by Shizam
    If I have a view (and its controller) and I override the willAnimateRotationToInterfaceOrientation method so I can respond to autorotation events everything works fine and dandy. Now if I create another viewController and add its view to the first viewController's view via: [firstViewController.view addSubview:secondViewController.view] The secondViewController's willAnimateRotationToInterfaceOrientation method isn't called. What gives? Thanks, Sam

  • How to make a table view which is not the full width of the screen?

    - by mystify
    For some strange reason, UITableView resizes my cells to 320 width no matter how I set the frame for the UITableView object. Even if I go in later and resize the cell back to 250, UITableView seems to resize it again to 320 some time. Is there some property or method that must be set / called additionally to get that right? However, I can add my contents in a way that it looks like 250 width, but my whole layouting code is a big mess since I can't rely on the cell frame width which is "wrong". Also it seems like a big waste of memory since the bitmaps in the layer trees are nonsenseless 320 width instead of 250, even though the frame of the UITableView is not 320 width.

  • Question about varrying top margin when using custom Fonts on the iPhone.

    - by user170030
    I am using FontLabel to display varying lengths of texts in a custom font. I size the FontLabel using the following : CGSize size = [myString sizeWithFont:[UIFont systemFontOfSize:[[[UIApplication sharedApplication] delegate] getFontSize]] constrainedToSize:CGSizeMake(290, 4000) lineBreakMode:UILineBreakModeWordWrap]; For some reason, this always presents a Fontlabel where the text starts at a different space from the top. Sometimes the text begins at the correct location. Other times, it appears either too high or too low. Would appreciate some help in how to solve this issue.

  • NSDirectoryEnumerator And Subfolders

    - by Matthew Roberts
    I have an iPhone app that searches a folder, collates an an array of all the audio files, and lets them be played back. The problem is that if there is a subfolder within the folder I am searching, it will just skip over it/not go into its contents. My code is as follows: NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); NSString *documentsDirectory = [paths objectAtIndex:0]; NSDirectoryEnumerator *direnum = [[NSFileManager defaultManager] enumeratorAtPath:documentsDirectory]; NSString *pname; while (pname = [direnum nextObject]) { [musicArray addObject:[pname stringByDeletingPathExtension]]; } What I want to do is continue to search its subfolders, how would I go about doing that?
