• IE10 - Progress bar animation issue

  - by user3723885

  I'm trying to incorporate some animated progress bars but I'm having trouble getting them to animate in IE10. I believe the problem is due to the keyframes being inside the media query but have not been able to get it working. Thanks for your help. HTML: <td><div style="width:150px;height:15px;border:1px solid black"> <div class="meter"> <span style="width:85%;"><span class="progress"></span></span> </div> </div></td></tr> CSS: .progress { background-color: #325C74; -webkit-animation: progressBar 3s ease-in-out; -webkit-animation-fill-mode:both; -moz-animation: progressBar 3s ease-in-out; -moz-animation-fill-mode:both; } @-webkit-keyframes progressBar { 0% { width: 0; } 100% { width: 100%; } } @-moz-keyframes progressBar { 0% { width: 0; } 100% { width: 100%; } }

• iPhone dev: UIBarButtonItem or title not showing up in NavigationBar

  - by IceMan85

  Hello everyone, here my problem. I have a NavigationBar at the top, a TabBar at the bottom and a TableView at the center of the screen. Very normal situation. I set it all up in IB and I have set this in the app delegate : ExpensesListNavController *expensesListNavController; This in order to be able to add new views to the stack. I need to have 3 levels: - list of items in a TableView - OK - firstLevel: once pressed one cell a view is added to the stack - OK - second level: one pressed the "modify" button on the navBar on the firstLevel I want to show a new view that can be customized by the user. My Problem is coming when trying to add the "Modify" button in the "firstLevelView". Here-below my code -(IBAction) modify:(id)sender { if (editableDetailViewController == nil) { editableDetailViewController = [[editableDetailViewController alloc] init]; } editableDetailViewController.expense = expense; [appDelegate.expensesListNavController pushViewController:editableDetailViewController animated:YES]; editableDetailViewController = nil; } // Implement viewDidLoad to do additional setup after loading the view, typically from a nib. - (void)viewDidLoad { [super viewDidLoad]; appDelegate = [[UIApplication sharedApplication] delegate]; UIBarButtonItem *modifyButton = [[UIBarButtonItem alloc] initWithTitle:@"Modify" style:UIBarButtonItemStylePlain target:self action:@selector(modify:)]; appDelegate.expensesListNavController.navigationItem.rightBarButtonItem = modifyButton; appDelegate.expensesListNavController.navigationItem.title = @"Titoloooo"; NSLog(@"NavBar button has just been set !!"); [modifyButton release]; Nothing is being showed, neither title nor the button. Do you have any idea of what is happening ?? I really cannot figure out !!! Thanks a lot in advance, AM

• Adding a footer to a table in another view?

  - by cannyboy

  The app I'm making has a settings view which I want to show on the first run of the app. Normally (after the first run) this view will be pushed onto the screen and there will be a "Back" button in the nav bar. However, on first launch I don't want there to be a back button. Instead, I want to add a 'Done' button at the footer of the table... and then the view can be popped. Here's my code (in my initial view's viewDidLoad). I have removed the back button, but don't know how to add the footer and button. NSUserDefaults *prefs = [NSUserDefaults standardUserDefaults]; if ([prefs stringForKey:@"firstRun"] == nil) { SettingsViewController *settingsView = [[SettingsViewController alloc] initWithNibName:@"SettingsView" bundle:nil]; settingsView.hidesBottomBarWhenPushed = YES; settingsView.navigationItem.hidesBackButton = TRUE; // add footer button here? [[self navigationController] pushViewController:settingsView animated:YES]; [settingsView release]; [prefs setObject:@"OK" forKey:@"firstRun"]; } else { //something }

• Stil facing the problem in Orientation in iphone

  - by aman-gupta

  Hi, In my application I have 15 screens in that i m using UIViewController for all screens and in all screens i m using the below way to call other screen :- AppDelegate *appRefre = (AppDelegate *)[[UIApplication sharedApplication]delegate]; [self.navigationController pushViewController:appRefre.frmReferencesLink animated:YES]; And the below code is activated in all screen for orientation to control the user to switch from one orientation to other mode (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation { if (interfaceOrientation == UIInterfaceOrientationPortrait) { return YES; } else { return NO; } } But when i run my application in iPhone device my application gets terminated when i physically rotate my iphone device from UIInterfaceOrientationPortrait to UIInterfaceOrientationPortraitUpsideDown or UIInterfaceOrientationLandscapeLeft,UIInterfaceOrientationLandscapeRight. And One more things is that when my application lauch i used following code for launching my appliaction :- 1) I made a pointer in mydelegate.h file: UINavigationController *navigationController; Then synthesize its property @property(nonatomic,retain)UINavigationController *navigationController 2) In mydelegat.m I Wrote @synthesize navigationController; (void)applicationDidFinishLaunching:(UIApplication *)application { navigationController = [[UINavigationController alloc] initWithRootViewController:DefaultViewLink]; [window addSubview:navigationController.view]; [window makeKeyAndVisible]; } 3) In above point DefaultView is launch first and gets remove from view and then actual my appliaction come into picture. So exactly what i want i want my appliaction to be in portrait mode for all screens i dont want my appliaction will switch to other mode.It remains the same as in portrait mode after rotation to any other mode. Please help me out its very urgent. Thanks in Advance and humble request to help me out

• Animate screen while loading textures

  - by Omega

  My RPG-like game has random battles. When the player enters a random battle, it is necessary for my game to load the textures used within that battle (animated monsters, animations, etc). The textures are quite a lot, and rather big (the battles are very graphical intensive). Such process consumes significant time. And while it is loading, the whole screen freezes. The game's map freezes, and the wait time is significant - I personally find it annoying. I can't afford to preload the textures because, after doing some math, I realized: If I preload all the textures at the beginning of the game, the application will definitely crash. If I preload the textures that are used in a specific map when the player enters the map, the application is very likely to crash as well. I can only afford to load the textures when I need them, and dispose of them as soon as the battle ends. I'd prefer to not use a "loading screen" image because it affects my game's design and concept. I want to avoid this approach. If I could do some kind of animation while loading the textures, it would be great, which leads to my question: is that possible? What kind of animation, you ask? Well, how about... you remember when Final Fantasy used to distort the screen while apparently loading the textures? Something like that. But well, distorting is quite a time-consuming process as well, so maybe just a cool frame-by-frame animation or something. While writing this, I realized that I could make small pauses between textures (there are multiple textures), and during such pauses, I update the screen to represent the animation's state. However, this is very unlikely to happen, because each texture is 2048x2048, so the animation would be refreshed at a rather laggy (and annoying) rate. I'd prefer to avoid this as well.

• Sharing NSMutableArray

  - by Lucas Veiga

  Hey everbody, im trying to share a NSMutableArray to another xib. The cartList.codigo is a NSMutableArray from a shared class, according to James Brannan's tutorial (http://www.vimeo.com/12164589). When i count it, it gives me 1. But when i load the another view, gives me 0. Whats wrong? View that adds: self.produtoCodigo = [[NSMutableArray alloc]init]; [self.produtoCodigo addObject:@"aa"]; CartViewController *carrinho = [[CartViewController alloc] initWithNibName:@"CartViewController" bundle:[NSBundle mainBundle]]; CartList *lista = [[CartList alloc] init]; carrinho.cartList = lista; carrinho.cartList.codigo = self.produtoCodigo; NSLog(@"QTD %i", [carrinho.cartList.codigo count]); View that wants to load the item added: - (void) viewDidAppear:(BOOL)animated { self.produtoCodigo = self.cartList.codigo; NSLog(@"%i", [self.produtoCodigo count]); [super viewDidLoad]; } Im loading the CartList class in both.

• iPhone -trouble with a loading data from webservice into a tableview

  - by medampudi

  I am using a Window based application and then loading up my initial navigationview based controller. After loading it if the user is not registered/ does not have a credentials present then it takes the user to a login view controller . loginViewController *sampleView = [[loginViewController alloc] initWithNibName:@"loginViewController" bundle:nil]; [self.navigationController presentModalViewController:sampleView animated:YES]; [sampleView release]; then right after that i try to load the table with data that i get from a webservice using asiHTTP .. for this question lets say it takes 3 seconds time to get the data and then deserialize it . now... my question is it works out okey in the later runs as I store the username and password in a seure location... but in the first instance.... i am not able to get the data to laod to the tableview... I have tried a lot of things... 1. Initially the data fetch methods was in a diffrent methods.. so i thought that might be the problem as then moved it the same place as the tbleviewController(navigationController) 2. I event put in the Reload data at the end of the functionality for the data parsing and deserialization... nothing happens. 3. i did not understand the concept of @property and alll.... 4. The screen is black screen with nothing displayed on it for a good 5 seconds in the consecutive launches of the app.... so could we have something like a MBPorgressHUD implemented for the same. could any one please help for these scenarios and guidance as to what paths to take from here...

• Need help getting parent reference to child view controller

  - by Andy

  I've got the following code in one of my view controllers: - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { switch (indexPath.section) { case 0: // "days" section tapped { DayPicker *dayPicker = [[DayPicker alloc] initWithStyle:UITableViewStylePlain]; dayPicker.rowLabel = self.activeDaysLabel; dayPicker.selectedDays = self.newRule.activeDays; [self.navigationController pushViewController:dayPicker animated:YES]; [dayPicker release]; break; ... Then, in the DayPicker controller, I do some stuff to the dayPicker.rowLabel property. Now, when the dayPicker is dismissed, I want the value in dayPicker.rowLabel to be used as the cell.textLabel.text property in the cell that called the controller in the first place (i.e., the cell label becomes the option that was selected within the DayPicker controller). I thought that by using the assignment operator to set dayPicker.rowLabel = self.activeDaysLabel, the two pointed to the same object in memory, and that upon dismissing the DayPicker, my first view controller, which uses self.activeDaysLabel as the cell.textLabel.text property for the cell in question, would automagically pick up the new value of the object. But no such luck. Have I missed something basic here, or am I going about this the wrong way? I originally passed a reference to the calling view controller to the child view controller, but several here told me that was likely to cause problems, being a circular reference. That setup worked, though; now I'm not sure how to accomplish the same thing "the right way." As usual, thanks in advance for your help.

• TabBar as rootController flip animation.

  - by user558076

  Hi there, I'm using a TabBarController as the root controller for my app. I have all the views I use (5 tabs) all hooked together through it in interface builder. What I'm trying to do is trigger a slide or flip animation when moving between tabs. However, I only want this to occur when I change tabs programmatically (ie the animation is triggered when someone does a swipe gesture in the one of the views, but not when they just select one of the tabs). The way I'm currently handling this is by calling: [appDelegate.myTab setSelectedIndex:0]; when the iphone detects a swipe. I've been searching the internet for 5 straight hours and can't seem to find a way to add an animation here. It'd be really cool if there were something like: [appDelegate.myTab setSelectedIndex:0 animated:(YES)]; However, there isn't... I can't imagine no one's ever tried this before, but for the life of me, I can't find anything online that explains how this can be done. Thank you in advance for your help.

• How to animate button text? (loading type of animation) - jquery?

  - by AL

  I got something that I want to do and want to see what you guys think and how can it be implemented. I got a form in a page and the form will submit to itself to perform some process (run functions) in a class. Upon clicking the submit button, I want to animate the button text to “SUBMIT .” -> “SUBMIT ..” -> “SUBMIT …” -> “SUBMIT ….” -> “SUBMIT ….” and then back again. Sort of “animate” the button text. Once the whole process is done, the button text will goes back to be “SUBMIT” text again. Please note that I am not looking for image button solution, meaning that I do not want to implement gif animated button image. Anyone done this before or know how this can be done? I have google but seems nothing of this kind to be found. Thanks! AL

• UITableView populating EVERY OTHER launch

  - by Joshmattvander

  I am having a problem that I cant seem to get to the bottom of. In my view did load code, I am creating an array and attempting to populate the table. For some reason it only populates the data on EVERY OTHER time the app is run. I put logs in viewDidLoad which runs as does viewWillAppear and outputs the correct count for the array. Also, the UITableView specicic methods get called when it works and they just don't get called when it doesnt work. I cant figure out the root of this problem. Again this occurrence happens exactly 50% of the time. Theres no dynamic data that could be tripping up or anything. #import "InfoViewController.h" @implementation InfoViewController - (void)viewDidLoad { NSLog(@"Info View Loaded"); // This runs infoList = [[NSMutableArray alloc] init]; //Set The Data //Theres 8 similar lines [infoList addObject :[[NSMutableDictionary alloc] initWithObjectsAndKeys: @"Scrubbed", @"name", @"scrubbed", @"url", nil]]; NSLog(@"%d", [infoList count]); // This shows the count correctly every time [super viewDidLoad]; } -(void) viewWillAppear:(BOOL)animated { NSLog(@"Info Will Appear"); // This Runs } - (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView { return 1; } - (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section { // This WILL NOT RUN when it doesnt work, and DOES show the count when it does run NSLog(@"Counted in numberOfRowsInSection %d", [infoList count]); return [infoList count]; } - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { NSLog(@"ROW"); static NSString *CellIdentifier = @"infoCell"; UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier]; if (cell == nil) { cell = [[[UITableViewCell alloc] initWithFrame:CGRectZero reuseIdentifier:CellIdentifier] autorelease]; } cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator; cell.textLabel.text = [[infoList objectAtIndex:indexPath.row] objectForKey:@"name"]; return cell; } @end

• Help adding a backgroundView to UITableViewCell

  - by Alex

  I'm getting really desperate trying to add a UIImageView to UITableViewCell.backgroundView. All my efforts have resulted in this crappy rendering: It looks like the cell's label's white background is sitting on top of cell's background and covering portions of it. I tried setting the label's background color to clear, or some other color and it does not have any event. It is always white. The reason I know it's the text label's background causing this white area is that if I don't do [cell setText:@"Cell text here"]; the white area is gone and I see just the cell's background image. Here's the code that I'm using. The table view is added in the .xib file and UITableView is added to UIViewController: - (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView { return 1; } - (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section { return [myCollection.items count]; } - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { NSUInteger rowIndex = indexPath.row; static NSString *CellIdentifier = @"Cell"; UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier]; if (cell == nil) { cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease]; cell.backgroundView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"darkCellBackground.png"]]; cell.selectedBackgroundView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"darkCellBackground.png"]]; } [cell setText:@"Cell text here"]; return cell; } - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { // Navigation logic may go here. Create and push another view controller. // AnotherViewController *anotherViewController = [[AnotherViewController alloc] initWithNibName:@"AnotherView" bundle:nil]; // [self.navigationController pushViewController:anotherViewController]; // [anotherViewController release]; [tableView deselectRowAtIndexPath:indexPath animated:YES]; } - (BOOL)tableView:(UITableView *)tableView canEditRowAtIndexPath:(NSIndexPath *)indexPath { return NO; } I'm sure I'm doing something wrong but cant quite figure out what.

• Switching between 2 UINavigationControllers

  - by Smikey

  Hi all, I seem to have a problem switching between 2 UINavigationControllers, i.e. one which controls the main (selection) menu of my application, and the second which controls the main session (i.e. the user can't go back to the selection menu once they're started a new session). The first works just fine, but I get into trouble when trying to load the second. I have a class called GameViewController which contains the second UINavigationController instance. I set this up as usual, linking it as an IBOutlet to the delegate and setting up the NavController in the GameViewController.xib file with its 'Class' property pointing at GameScreenViewController (my main game screen), and its NIB Name property pointing to the GameScreenViewController nib file. I then create a new instance of GameViewController and load it. In IB, the navigation controller looks fine, with its View 'loaded from "GameScreenViewController"', however when the NavigationController is loaded in the game, it actually loads the GameViewController's UIWindow instance (just a blank window). I'm not sure how to make it load the Navigation Controller's view rather than its own window? Also, another quick question. When I load the second navigation controller from the first, which makes more sense to use: [self.view addSubview:gameViewController.view]; or [self presentModalViewController:gameViewController animated:YES]; Thanks for any help, much appreciated :D Michael

• View Controller Question

  - by user341444

  First off I'm new at programming. I'm creating an app with one navigation bar controller. The app is pretty basic except for a quiz section that is comprised of 12 xibs. As the users takes the quiz a new xib is pushed onto the stack. I want to create a button that takes the user back to the home screen if they do not want to complete the quiz. The back button takes them to the previous xib which could be 11 deep. Is it possible to dismiss the modal views and reload the rootView controller? Here's the code from my delegate @synthesize window; @synthesize navigationController; (void)applicationDidFinishLaunching:(UIApplication *)application { // Override point for customization after application launch [window addSubview:[navigationController view]]; [window makeKeyAndVisible]; } (void)dealloc { [window release]; [navigationController release]; [super dealloc]; } This is how I'm pushing new xibs onto the stack (IBAction) showTesting: (id)sender { Testing *varTesting = [[[Testing alloc] initWithNibName:@"Testing" bundle:nil] autorelease]; [[self navigationController] pushViewController:varTesting animated: YES]; } Any help would be greatly appreciated. Thanks

• UIViewController maintains state after being nilled

  - by Eric

  In my app, I made a BookViewController class that displays and animates the pages of a book and a MainMenuViewController class that displays a set of books the user can read. In the latter class, when the user taps on one of the books, a function is called that should create a completely new instance of BookViewController, but for some reason the instance maintains its state (i.e. it resumes from the page the user left off). How can this be if I set it to nil? What am I missing here? (Note that I'm using ARC). MainMenuViewController.m @interface MainMenuViewController () @property (strong) BookViewController *bookViewController; @end @implementation MainMenuViewController @synthesize bookViewController; -(void)bookTapped:(UIButton *)sender{ NSString *bookTitle; if(sender == book1button) bookTitle = @"book1"; else if(sender == book2button) bookTitle = @"book2"; bookViewController = nil; bookViewController = [[BookViewController alloc] initWithBookTitle:bookTitle]; [self presentViewController:bookViewController animated:YES completion:nil]; } BookViewController.h @interface BookViewController : UIViewController -(id)initWithBookTitle:(NSString *)bookTitle; @end BookViewController.m @implementation BookViewController -(id)initWithBookTitle:(NSString *)theBookTitle{ self = [super init]; if(self){ bookTitle = [NSString stringWithFormat:@"%@", theBookTitle]; [self setModalTransitionStyle:UIModalTransitionStyleCrossDissolve]; NSLog(@"init a BookViewController with bookTitle: %@", bookTitle); } return self; } Every time a book is tapped, bookTapped: is called, and thee console always prints: 2012-08-31 16:29:51.750 AppName[25713:c07] init a BookViewController with bookTitle: book1 So if a new instance of BookViewController is being created, how come it seems to be returning the old one?
