  • iphone integer multiplication

    - by Rob
    I don't understand why this doesn't work: [abc = ([def intValue] - 71) * 6]; '*' should be the viable way of doing multiplication and 'abc' is defined as an NSInteger. ('def' is an NSString)

  • How to Promote iPhone App

    - by Ricibald
    I published my app. I request a review to more than 150 sites but only 8 of them give me a (good) review. I can't reach the most famous blogs because I have to pay to bring on top of their queue. Now, my app seems to be nice but I have only 65 users playing it. This 65 users seems to really like it because I can see there are a lot of games played tracked in my stats. A lot of users say that my app is "fun like Doodle Jump and very addictive". So, what's the problem? Why only 65 people? In a word, how can simple games such "Doodle Jump" or "Flight Control" enter in top 10? What's their secret? What's my mistake? UPDATE: I have a site describing my app.

  • Resizing Tab Bar Controller Views (iPhone dev)

    - by damiandawber
    Hello, I have an application set up where the window contains a tab bar controller and one of the tabs loads a NIB called 'ShowCaseView.xib': this file is owned by a custom ShowcaseViewController class. In the ShowcaseViewcontroller class I have added a UIScrollView object, like so: imageScrollView = [[UIScrollView alloc] initWithFrame:[[self view] bounds]]; [[self view] addSubview:imageScrollView]; The issue I am having is that this UIScrollView object extends beneath my tab bar controller. So I have had to reduce its insets manually: #define TAB_BAR_HEIGHT 48 . . UIEdgeInsets edgeInsets = UIEdgeInsetsMake(0, 0, TAB_BAR_HEIGHT, 0); [imageScrollView setScrollIndicatorInsets:edgeInsets]; So, Is it common to have to manually deduct the tab bar height from a view (whether this be by reducing the size of subviews or the View NIB in inspector)? Is there a way that I can tell a NIB's view loaded from a tab bar to resize itself automatically to NOT sit behind the tab bar? Cheers

  • iphone: accessing the preferences localization file from code

    - by phonecoddy
    I was just facing the following problem and couldn't find a solution for it. Hopefully someone could help. The app I am working on has some preferences, which are using a localization file. Now I want to use labels in my app, which display the exact names, which are used in the localization file for the preferences. But I couldn't find a way to access the information which is stored in Settings.bundle - en.lproj - localizationfile.strings. to make this clear: If you open your preferences for your app, the display shows the localized string of the title and the value of the setting. I need to access the localized string of the title of each preference from my code. Does any know how to do this?

  • iPhone: detect "touch-and-drag" gesture from UIBarButtonItem?

    - by Greg Maletic
    I have an "add" button that's represented by a UIBarButtonItem. Hitting the "add" button adds an object into a list that represents a moment in time. By default, that time is "now"...but I'd like to be able to use dragging behavior to let the user specify earlier times for the object. Here's the behavior I want to implement: If the user touches on the UIBarButtonItem and lets go quickly, an object is added to the list that represents "now." If the user touches on the UIBarButtonItem and drags, a little UI pops up that shows the time that the distance of their drag represents. The further they drag, the further back in time their touch will represent. When they let go, the object representing an earlier time will get added to the list. (Though the description of the behavior is complicated, I'm convinced this will be pretty intuitive for users of the app.) I haven't implemented code for anything but the most simple touches in the past, and I'm at a loss as to the best way to try this. Does anyone have any suggestions, or could point me towards some sample code that implements something like this? Thanks very much.

  • Android-iPhone single codebase

    - by Lorenzo
    Is there a way, apart from using HTML and JavaScript on a web control, to have an (almost) single codebase for an application that should run on iOS and Android? The big issue is of course that they use a different language (Java for Android, Objective-C for iOS) for application development. It would be nice to have some sort of meta-language that will be translated in Java and in Objective-C. What about Flash? Adobe wasn't supposed to release a tool to create flash-based apps in iOS?

  • iPhone checklist app

    - by Brodie4598
    I am trying to create a simple app that displays a list of items with check boxes next to each item, then give the user to simply check each box. Nothing (aside from the checkbox image switching) needs to happen when the check box is touched. Each checklist is a seperate NSDictionary contained in a single master NSDictionary. The checklist dictionary contains arrays for different sections of each checklist. At the top of the view, the user selects which set (dictionary) of checklists they want to open then I want that checklist to display underneath the picker once a "select checklist" button is pressed. Any ideas on the best way to get this done?

  • Async call Objective C iphone

    - by Sam
    Hi guys, I'm trying to get data from a website- xml. Everything works fine. But the UIButton remains pressed until the xml data is returned and thus if theres a problem with the internet service, it cant be corrected and the app is virtually unusable. here are the calls: { AppDelegate *appDelegate = (AppDelegate *)[[UIApplication sharedApplication] delegate]; if(!appDelegate.XMLdataArray.count > 0){ [UIApplication sharedApplication].networkActivityIndicatorVisible = YES; [appDelegate GetApps]; //function that retrieves data from Website and puts into the array - XMLdataArray. } XMLViewController *controller = [[XMLViewController alloc] initWithNibName:@"MedGearsApps" bundle:nil]; [self.navigationController pushViewController:controller animated:YES]; [controller release]; } It works fine, but how can I make the view buttons functional with getting stuck. In other words, I just want the UIButton and other UIButtons to be functional whiles the thing works in the background. I heard about performSelectorInMainThread but i cant put it to practice correctly any help is appreciated :)

  • TabBar implementation issue in iphone

    - by iPhoneDev
    Hi, My project is navigation based template and it was running fine until I made changes in some child view. I need to add 4 Tab in some child view. So what I did is create a TabBarController programmatically on ViewDidLoad as: // (void)viewDidLoad { [super viewDidLoad]; helpView = [[HelpView alloc] initWithNibName:@"HelpView" bundle:nil]; settingView = [[SettingView alloc] initWithNibName:@"SettingView" bundle:nil]; tabBarController = [[UITabBarController alloc] init]; tabBarController.viewControllers = [NSArray arrayWithObjects:helpView,settingView,nil]; [self.view addSubview:[tabBarController view]]; } I am able to add two view in tab bar but not Tab Title. Please let me know what I am missing to display Title on tab button. ( Is a NavigationBased project) Thanks

  • Sending information back from delegate [iPhone]

    - by Andy
    I'm using NSXMLParser in my RootViewController.m file. NSXMLParser *xmlParser = [[NSXMLParser alloc] initWithData:response_data]; [xmlParser setDelegate:self]; [xmlParser parse]; [xmlParser release]; I'm also implementing this method to add entries to a dictionary defined in RootViewController.m for later use: - (void)parser:(NSXMLParser *)parser didStartElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qualifiedName attributes:(NSDictionary *)attributeDict However, I'd like to get more than one XML file and do different things when the file has finished; this sounds like I need to use external files as delegates. My question is: If I have the following implementation files (& their header files): RootViewController.m XMLDelegate1.m XMLDelegate2.m and set the ith NSXMLParser delegate to be XMLDelegatei.m, and get those files to return an NSDictionary that I can then add to the NSDictionary defined in RootViewController.m. I guess there are two methods of doing this: Use a method that I don't know about; or Use a better workflow I suspect it's 2, but hope it's 1. Thanks, Andy

  • iphone instance / class method issue

    - by user290031
    Hey All, Okay, so I have a viewController method that has some elements created with interface builder and some I coded myself. I created a view in the IB...lets call it viewOne. I created a loop that creates buttons (through code) and places them on a separate view (viewTwo). This is done in a class method. However, I want the view I made to be opened everytime one of the buttons is clicked. So I did: [button addTarget:self action:@selector(woogoo:) forControlEvents:UIControlEventTouchUpInside]; The woogoo class does the following: +(void) woogoo:(id)sender { //back button [self.view addSubview:viewOne] } However, the program crashes when a button is clicked. I did try making woogoo an instance method but it also crashes in this case too. All I want to do is show viewOne when a button is clicked. Any ideas what I can do?

  • how can I know current viewcontroller name in iphone

    - by Shikhar
    I have BaseView which implement UIViewController. Every view in project must implement this BaseView. In BaseView, I have method: -(void) checkLoginStatus { defaults = [[NSUserDefaults alloc] init]; if(![[defaults objectForKey:@"USERID"] length] > 0 ) { Login *login=[[Login alloc] initWithNibName:@"Login" bundle:nil]; [self.navigationController pushViewController:login animated:TRUE]; [login release]; } [defaults release]; } The problem is my Login view also implement BaseView, checks for login, and again open LoginView i.e. stuck in to recursive calling. Can I check in checkLoginStatus method if request is from LoginView then take no action else check login. Ex: (void) checkLoginStatus { if(SubView is NOT Login){ defaults = [[NSUserDefaults alloc] init]; if(![[defaults objectForKey:@"USERID"] length] 0 ) { Login *login=[[Login alloc] initWithNibName:@"Login" bundle:nil]; [self.navigationController pushViewController:login animated:TRUE]; [login release]; } [defaults release]; } } Please help..

  • Implementing Multitasking on an iPhone/iOS4 Web App

    - by Peter Watts
    I am looking to build a web app that implements background audio and fast app switching. These features work out of the box, when run as regular Safari web pages, but as soon as you add the web-app-capable tag, and try to run in full screen mode, this functionality breaks. I did some testing and even the most basic web app will reload every time when you switch back to it. And seeing as it's a web app, we can't exactly implement the multitasking API. Has anyone found a work around? This isn't a deal-breaker, as you can just avoid full screen mode, but then you also lose the ability to use your own icon in the app switch tray. Perhaps this explains a lack of full screen mode in YouTube's new web app....
