  • Unbalanced calls to begin/end appearance transitions for <ViewController>,<Tab>

    - by onkar
    I am trying to implement Tabs into my secondView.On button touch(from ViewController.m) I am navigating to secondView(Tabs).

  • iPhone scrollView won't scroll after keyboard is closed

    - by Rob
    I was trying to implement a way to have the UITextField move up when the keyboard opened so that the user could see what they were typing but after implementing the code - it locks my scroll. The view will scroll when the user first gets to that view but after inputting text and closing the keyboard it locks the view. I suspect that it is a problem somewhere in this code: - (void) viewWillAppear:(BOOL)animated { [super viewWillAppear:animated]; NSLog(@"Registering for keyboard events"); // Register for the events [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector (keyboardDidShow:) name: UIKeyboardDidShowNotification object:nil]; [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector (keyboardDidHide:) name: UIKeyboardDidHideNotification object:nil]; // Setup content size scrollView.contentSize = CGSizeMake(SCROLLVIEW_CONTENT_WIDTH, SCROLLVIEW_CONTENT_HEIGHT); //Initially the keyboard is hidden keyboardVisible = NO; } -(void) viewWillDisappear:(BOOL)animated { NSLog (@"Unregister for keyboard events"); [[NSNotificationCenter defaultCenter] removeObserver:self]; } //**-------------------------------** - (void) keyboardDidShow: (NSNotification *)notif { NSLog(@"Keyboard is visible"); // If keyboard is visible, return if (keyboardVisible) { NSLog(@"Keyboard is already visible. Ignore notification."); return; } // Get the size of the keyboard. NSDictionary* info = [notif userInfo]; NSValue* aValue = [info objectForKey:UIKeyboardBoundsUserInfoKey]; CGSize keyboardSize = [aValue CGRectValue].size; // Save the current location so we can restore // when keyboard is dismissed offset = scrollView.contentOffset; // Resize the scroll view to make room for the keyboard CGRect viewFrame = scrollView.frame; viewFrame.size.height -= keyboardSize.height; scrollView.frame = viewFrame; CGRect textFieldRect = [activeField frame]; textFieldRect.origin.y += 10; [scrollView scrollRectToVisible:textFieldRect animated:YES]; NSLog(@"ao fim"); // Keyboard is now visible keyboardVisible = YES; } -(void) keyboardDidHide: (NSNotification *)notif { // Is the keyboard already shown if (!keyboardVisible) { NSLog(@"Keyboard is already hidden. Ignore notification."); return; } // Reset the frame scroll view to its original value scrollView.frame = CGRectMake(0, 0, SCROLLVIEW_CONTENT_WIDTH, SCROLLVIEW_CONTENT_HEIGHT); // Reset the scrollview to previous location scrollView.contentOffset = offset; // Keyboard is no longer visible keyboardVisible = NO; } -(BOOL) textFieldShouldBeginEditing:(UITextField*)textField { activeField = textField; return YES; } I defined the size above the #imports as: #define SCROLLVIEW_CONTENT_HEIGHT 1000 #define SCROLLVIEW_CONTENT_WIDTH 320 Really not sure what the issue is.

  • iPhone SDK: Orientation (Landscape and Portrait views)

    - by domness
    Okay, I've got my normal app which is in portrait mode. I can force my app to go to landscape mode for a view (using navigationcontroller and viewcontroller) like this: - (void)viewWillAppear:(BOOL)animated { [[UIDevice currentDevice] setOrientation:UIInterfaceOrientationLandscapeRight]; } But then when I go back to the main menu (tableview) it goes straight back to portrait. I try this code: - (void)viewWillAppear:(BOOL)animated { [[UIDevice currentDevice] setOrientation:UIInterfaceOrientationPortrait]; } But that doesn't work.. Any ideas?

  • [Java2D] Is this bad practice? Multiple Graphics2D Objects

    - by m00st
    I've created a JPanel canvas that holds all graphics; namely JLabel. To get animated sprites to work you have to over ride the paintComponent of the extended JLabel class. I've successfully implemented animated sprites this way. Is it bad practice to have a Graphics2D canvas and then have multiple 'images' in their own Graphics2D?

  • Direct 2D gnuplot PNG animation?

    - by Xepoch
    Can anyone please confirm that yes/no Gnuplot 4.5 (on CVS) can output 2D animated PNG files? I have numerous datasets but one line that I'd like to show iteratively in 3 different places in my graph. Can this be done directly from gnuplot or is this something that would need to be animated externally from multiple frames?

  • Programatically created UITableViewCell subclass only working on highlight

    - by squarefrog
    I've created a subclass of UITableViewCell but I'm struggling to get it to work properly. If I use UITableViewStyleDefault then the class only works when highlighted. If I use UITableViewStyleValue1 then it mostly works but I'm unable to change label fonts much. I tried researching but it seems everyone is doing this via a .xib file, but not programatically.

  • Making firefox refresh images faster

    - by Earlz
    I have a thing I'm doing where I need a webpage to stream a series of images from the local client computer. I have a very simple run here: http://jsbin.com/idowi/34 The code is extremely simple setTimeout ( "refreshImage()", 100 ); function refreshImage(){ var date = new Date() var ticks = date.getTime() $('#image').attr('src','http://127.0.0.1:2723/signature?'+ticks.toString()); setTimeout ("refreshImage()", 100 ); } Basically I have a signature pad being used on the client machine. We want for the signature to show up in the web page and for them to see themselves signing it within the web page(the pad does not have an LCD to show it to them right there). So I setup a simple local HTTP server which grabs an image of what the current state of the signature pad looks like and it gets sent to the browser. This has no problems in any browser(tested in IE7, 8, and Chrome) but Firefox where it is extremely laggy and jumpy and doesn't keep with the 10 FPS rate. Does anyone have any ideas on how to fix this? I've tried creating very simple double buffering in javascript but that just made things worse. Also for a bit more information it seems that Firefox is executing the javascript at the correct framerate as on the server the requests are coming in at a constant speed. But the images are only refreshed inconsistently ranging from 5 times per second all the way down to 0 times per second(taking 2 seconds to do a refresh) Also I have tried using different image formats all with the same results. The formats I've tried include bitmaps, PNGs, and GIFs (GIFs caused a minor problem in Chrome with flicker though) Could it be possible that Firefox is somehow caching my images causing a slight lag? I send these headers though: Pragma-directive: no-cache Cache-directive: no-cache Cache-control: no-cache Pragma: no-cache Expires: 0

  • Creating Drill-Down Detail UITableView from JSON NSDictionary

    - by Michael Robinson
    I'm have a load of trouble finding out how to do this, I want to show this in a UITableDetailView (Drill-Down style) with each item in a different cell. All of the things I've read all show how to load a single image on the detail instead of showing as a UITableView. Does the dictionary have to have "children" in order to load correctly? Here is the code for the first view creating *dict from the JSON rowsArray. I guess what I'm looking for is what to put in the FollowingDetailViewController.m to see the rest of *dict contents, so when selecting a row, it loads the rest of the *dict. I have rowsArray coming back as follows: '{ loginName = Johnson; memberid = 39; name = Kris; age = ;}, etc,etc... Thanks, // SET UP TABLE & CELLS - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *CellIdentifier = @"Cell"; UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier]; if (cell == nil) { cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier] autorelease]; } NSDictionary *dict = [rowsArray objectAtIndex: indexPath.row]; cell.textLabel.text = [dict objectForKey:@"name"]; cell.detailTextLabel.text = [dict objectForKey:@"loginName"]; cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator; return cell; } - (void)viewDidAppear:(BOOL)animated { [super viewDidAppear:animated]; - (void)viewDidLoad { [super viewDidLoad]; //GET JSON FROM WEBSERVICES: NSURL *url = [NSURL URLWithString:@"http://10.0.1.8/~imac/iphone/jsontest.php"]; NSString *jsonreturn = [[NSString alloc] initWithContentsOfURL:url]; NSData *jsonData = [jsonreturn dataUsingEncoding:NSUTF32BigEndianStringEncoding]; NSError *error = nil; NSDictionary * dict = [[CJSONDeserializer deserializer] deserializeAsDictionary:jsonData error:&error]; if (dict) { rowsArray = [dict objectForKey:@"member"]; [rowsArray retain]; } [jsonreturn release]; } //GO TO DETAIL VIEW: - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { FollowingDetailViewController *aFollowDetail = [[FollowingDetailViewController alloc] initWithNibName:@"FollowingDetailView" bundle:nil]; [self.navigationController pushViewController:aFollowDetail animated:YES]; }

  • Keyboard Animation Issues When Calling becomeFirstResponder within a Modal View Controller

    - by LucasTizma
    I've been having some issues with calling -becomeFirstResponder on a UITextField contained with a view controller that is presented modally. I call this method in the modal view controller's -viewDidLoad method so that the keyboard is immediately displayed. What I expected is for both the keyboard and the modal view controller to animate from up the bottom of the screen at the same time. However, what I'm observing is the following: There is a ~0.2 second UI lag between clicking the button that calls the -presentModalViewController:animated: method on the parent view controller and when the child view controller begins to animate modally. The keyboard is immediately presented with absolutely no animation about half-way through the modal view controller's animation. Once the modal view controller's animation is complete, everything else seems to operate smoothly. Dismissing the modal view controller results in it being smoothly animated off screen (along with the keyboard, coincidentally). It's as if the keyboard's animation and the modal view controller's animation are both competing for some lower-level Core Animation resource at the same time, but I don't see why this should be happening. What further seems to corroborate this hunch is if I don't ask the UITextField to become the first responder (i.e., if I don't ask the keyboard to present itself), then there is absolutely no UI lag, and the modal view controller animates instantly. Interestingly, if I do something like [self.textField performSelector:@selector(becomeFirstResponder) withObject:nil afterDelay:0.0001]; then the animation of the keyboard happens nearly at the same time as the modal view controller's animation -- it's extremely difficult to tell that they aren't both being animated at the exact same time. Furthermore, there's no more UI lag. Has anyone experienced anything similar to this?

    I've followed the guides helpfully linked here: http://stackoverflow.com/questions/295778/iphone-debugging-pointer-being-freed-was-not-allocated-errors but the malloc_history is really throwing me for a loop, can anyone shed any light on the following: ALLOC 0x185c600-0x18605ff [size=16384]: thread_a068a4e0 |start | main | UIApplicationMain | -[UIApplication _run] | CFRunLoopRunInMode | CFRunLoopRunSpecific | PurpleEventCallback | _UIApplicationHandleEvent | -[UIApplication sendEvent:] | -[UIApplication handleEvent:withNewEvent:] | -[UIApplication _reportAppLaunchFinished] | CA::Transaction::commit() | CA::Context::commit_transaction(CA::Transaction*) | CALayerCommitIfNeeded | CALayerCommitIfNeeded | CALayerCommitIfNeeded | CALayerCommitIfNeeded | CALayerCommitIfNeeded | CALayerCommitIfNeeded | CA::Context::commit_layer(_CALayer*, unsigned int, unsigned int, void*) | CA::Render::encode_set_object(CA::Render::Encoder*, unsigned long, unsigned int, CA::Render::Object*, unsigned int) | CA::Render::Layer::encode(CA::Render::Encoder*) const | CA::Render::Image::encode(CA::Render::Encoder*) const | CA::Render::Encoder::encode_data_async(void const*, unsigned long, void (*)(void const*, void*), void*) | CA::Render::Encoder::encode_bytes(void const*, unsigned long) | CA::Render::Encoder::grow(unsigned long) | realloc | malloc_zone_realloc ---- FREE 0x185c600-0x18605ff [size=16384]: thread_a068a4e0 |start | main | UIApplicationMain | -[UIApplication _run] | CFRunLoopRunInMode | CFRunLoopRunSpecific | PurpleEventCallback | _UIApplicationHandleEvent | -[UIApplication sendEvent:] | -[UIApplication handleEvent:withNewEvent:] | -[UIApplication _reportAppLaunchFinished] | CA::Transaction::commit() | CA::Context::commit_transaction(CA::Transaction*) | CALayerCommitIfNeeded | CALayerCommitIfNeeded | CALayerCommitIfNeeded | CALayerCommitIfNeeded | CALayerCommitIfNeeded | CALayerCommitIfNeeded | CA::Context::commit_layer(_CALayer*, unsigned int, unsigned int, void*) | CA::Render::encode_set_object(CA::Render::Encoder*, unsigned long, unsigned int, CA::Render::Object*, unsigned int) | CA::Render::Layer::encode(CA::Render::Encoder*) const | CA::Render::Image::encode(CA::Render::Encoder*) const | CA::Render::Encoder::encode_data_async(void const*, unsigned long, void (*)(void const*, void*), void*) | CA::Render::Encoder::encode_bytes(void const*, unsigned long) | CA::Render::Encoder::grow(unsigned long) | realloc | malloc_zone_realloc ALLOC 0x185e000-0x185e62f [size=1584]: thread_a068a4e0 |start | main | UIApplicationMain | GSEventRun | GSEventRunModal | CFRunLoopRunInMode | CFRunLoopRunSpecific | __NSFireDelayedPerform | -[UITableView _userSelectRowAtIndexPath:] | -[UITableView _selectRowAtIndexPath:animated:scrollPosition:notifyDelegate:] | -[PLAlbumView tableView:didSelectRowAtIndexPath:] | -[PLUIAlbumViewController albumView:selectedPhoto:] | PLNotifyImagePickerOfImageAvailability | -[UIImagePickerController _imagePickerDidCompleteWithInfo:] | -[GalleryViewController imagePickerController:didFinishPickingMediaWithInfo:] | UIImageJPEGRepresentation | CGImageDestinationFinalize | _CGImagePluginWriteJPEG | writeOne | _cg_jpeg_start_compress | _cg_jinit_compress_master | _cg_jinit_c_prep_controller | alloc_sarray | alloc_large | malloc | malloc_zone_malloc ---- FREE 0x185e000-0x185e62f [size=1584]: thread_a068a4e0 |start | main | UIApplicationMain | GSEventRun | GSEventRunModal | CFRunLoopRunInMode | CFRunLoopRunSpecific | __NSFireDelayedPerform | -[UITableView _userSelectRowAtIndexPath:] | -[UITableView _selectRowAtIndexPath:animated:scrollPosition:notifyDelegate:] | -[PL AlbumView tableView:didSelectRowAtIndexPath:] | -[PLUIAlbumViewController albumView:selectedPhoto:] | PLNotifyImagePickerOfImageAvailability | -[UIImagePickerController _imagePickerDidCompleteWithInfo:] | -[GalleryViewController imagePickerController:didFinishPickingMediaWithInfo:] | UIImageJPEGRepresentation | CGImageDestinationFinalize | _CGImagePluginWriteJPEG | writeOne | _cg_jpeg_abort | free_pool | free ALLOC 0x185c800-0x185ea1f [size=8736]: thread_a068a4e0 |start | main | UIApplicationMain | GSEventRun | GSEventRunModal | CFRunLoopRunInMode | CFRunLoopRunSpecific | __NSFireDelayedPerform | -[UITableView _userSelectRowAtIndexPath:] | -[UITableView _selectRowAtIndexPath:animated:scrollPosition:notifyDelegate:] | -[PLAlbumView tableView:didSelectRowAtIndexPath:] | -[PLUIAlbumViewController albumView:selectedPhoto:] | PLNotifyImagePickerOfImageAvailability | -[UIImagePickerController _imagePickerDidCompleteWithInfo:] | -[GalleryViewController imagePickerController:didFinishPickingMediaWithInfo:] | -[UIImage initWithData:] | _UIImageRefFromData | CGImageSourceCreateImageAtIndex | makeImagePlus | _CGImagePluginInitJPEG | initImageJPEG | calloc | malloc_zone_calloc

  • Hiding a UINavigationController's UIToolbar during viewWillDisappear:

    - by Nathan de Vries
    I've got an iPhone application with a UITableView menu. When a row in the table is selected, the appropriate view controller is pushed onto the application's UINavigationController stack. My issue is that the MenuViewController does not need a toolbar, but the UIViewControllers which are pushed onto the stack do. Each UIViewController that gets pushed calls setToolbarHidden:animated: in viewDidAppear:. To hide the toolbar, I call setToolbarHidden:animated: in viewWillDisappear:. Showing the toolbar works, such that when the pushed view appears the toolbar slides up and the view resizes correctly. However, when the back button is pressed the toolbar slides down but the view does not resize. This means that there's a black strip along the bottom of the view as the other view transitions in. I've tried adding the toolbar's height to the height of the view prior to hiding the toolbar, but this causes the view to be animated during the transition so that there's still a black bar. I realise I can manage my own UIToolbar, but I'd like to use UINavigationControllers built in UIToolbar for convenience. This forum post mentions the same issue, but no workaround is mentioned.
