Try searching for NSSearchPathForDirectoriesInDomains in your documentation viewer and read the associated guides.
You can also use something like "~/Library/Application Support/Xxx" as your directory and use tilde expansion to get the actual file path. Create this the first time and then use as you wish.

  • Caching Content on iPhone

    My iPhone application downloads content from the web. I want to cache some of this content so that it doesn't have to hit the web everytime.
    How do I do that? Where would I store the files? I have read that there is the documents folder, how do I get to that? Is that the right place to store the files? Or is there a temporary folder?
    Is there some code sample I can use?

  • Can you sync 2 apple ID's for Find Iphone Application?

    My Husband & I both have IPhone/IPad/IPod & MacBooks and we have seperate Apple ID's. We would both like to be able to access all the devices under the Find IPhone application, but I can only see my devices and he can only see his. Is there a way to sync the two apple ID's? Thank you!

    Yes if she has her own user account on the MacBook.  One user account can't sync to two separate iCloud accounts.

  • Flex iPad Application : Run code before application enters background  Application Type: Flex Mobile Application Target Platform: iPad AIR Version: 4.0 Development Environment: Flash builder 4.6  I want to run some code just before iphone application goes

    Application Type: Flex Mobile Application
    Target Platform: iPad
    AIR Version: 4.0
    Development Environment: Flash builder 4.6
    I want to run some code just before iphone application goes into background. I need function similar to didEnterBackground
    of native xcode app
    (https://developer.apple.com/library/ios/documentation/UIKit/Reference/UIApplicationDelegat e_Protocol/Reference/Reference.h
    tml#//apple_ref/occ/intfm/UIApplicationDelegate/applicationDidEnterBackground:)
    I tried using devactivated function of flash.display.STAGE.
    I used following addEventListener:
    STAGE = this.parent.stage;
    STAGE.addEventListener(Event.DEACTIVATE, onAppDeactivated);
    It worked for me but only when device is connected to development environment in debug mode. When I create my release build
    it is not working.
    So how can I make sure that my code runs before application goes into background.

    Even I am facing almost same issue

  • Massive help with an iPhone Application...PLEASE!   :(

    Hello.
    Since yesterday I have been trying to hunt down a bug in a simple iPhone application I made while following an exercise from the iPhone SDK Development book. Its a simple application with a navigation controller and a table view.
    You can download my project at
    public.me.com/felipelaso
    In the main view when the application is opened, you see a list of items and an option to edit them or add an item. When you click on add, a new view controller is popped, you get a textfield and a keyboard, and when you are done you go back to the table view and the name you just entered is added to the list.
    The problem is that as soon as you hit done on the keyboard, or click back on the navigation bar I get the following messages in the console:
    This GDB was configured as "i386-apple-darwin".warning: Unable to read symbols for "/System/Library/Frameworks/CoreGraphics.framework/CoreGraphics" (file not found).
    warning: Unable to read symbols from "CoreGraphics" (not yet mapped into memory).
    warning: Unable to read symbols for "/System/Library/Frameworks/UIKit.framework/UIKit" (file not found).
    warning: Unable to read symbols from "UIKit" (not yet mapped into memory).
    I have reinstalled my developer tools, created a new project from scratch, added the frameworks again and nothing seems to work.
    I though it might me something with my frameworks. But then I downloaded a bunch of the samples with table views and navigation controllers, and they all work fine. All my other applications work fine too, except this one.
    I have spent all morning, and all afternoon yesterday trying to find out whats wrong, but im not an Xcode or Cocoa expert and I was hoping I could find some help.
    The project can be downloaded for anyone to test with.
    Please! any help I get would be gladly appreciated.
    Thanks in Advance,
    Felipe.

    Ok I downloaded it, ran it on the simulator and everything was fine. Put it on my device and i got an EXCBADACCESS when I clicked the done button as you described.
    EXCBADACCESS means something is getting released before you're trying to access it again. I opened the debug console to see this. Then I opened the debugger to find out exactly what the issue is. In my stack the last custom method that was called is [RootViewController addTeamNamed:] This makes me believe the array is being released.
    Now I take your addTeamNamed method and pepper it with log statements:
    - (void)addTeamNamed:(NSString *)teamName
    NSLog( @"A" );
    [teams addObject:teamName];
    NSLog( @"B" );
    NSIndexPath *indexPath;
    indexPath = [NSIndexPath indexPathForRow:[teams indexOfObject:teamName] inSection:0];
    NSLog( @"C" );
    [[self tableView] insertRowsAtIndexPaths:[NSArray arrayWithObjects:indexPath] withRowAnimation:NO];
    NSLog( @"D" );
    The console output of which is: "A B C". Ok, no D, so that means the error is the in the insertRows... method.

  • How can I earn money with my iPhone application?

    Basically, Navizon adds to the basic location services of your iPhone. Your handset can determine your location using a combination of cell towers, Wi-Fi, and GPS, but using the included Maps application, you have no way of knowing which is active at any given time. Navizon displays your position (on Yahoo!, rather than Google Maps), but it also displays a little badge to let you know which method is being used to determine where you are. That way I know, for example, why the map was showing me as located three blocks North of where I actually am. The answer? My phone was only using cell tower data to find me. You can also take advantage of built-in buddy features to locate friends or family, if they’re using Navizon’s service. You can also configure alerts by logging on to the website to receive notifications by email or web when your buddies enter into specific areas you designate. The most interesting feature of the app, one that I hinted at earlier, is how you can receive cash rewards for using it. In order to continue to build out their extensive database of cell and Wi-Fi towers, Navizon is offering a rewards system similar to air miles, but without the free flights. Instead, compensation is based on accumulating enough points. Also, in this case, it’s actually the number of towers, not the number of miles you’re being rewarded for. For first-time finds, you get 15 points for every cell tower mapped, and 3 for every Wi-Fi access point. If they’ve already been found before, you get 2 for every cell tower and 1 for every access point. Once you’ve accumulated 10,000, Navizon will wire $10 to your bank account.
    No, you can’t retire on that kind of money, but if you’re already using your phone to log trails or track your pals, it pays more than the competition, at least. You can get the Lite version [iTunes] in the App Store for free, while the full version [iTunes] costs $9.99. 10,000 points and it pays for itself!

  • Question about update to iphone application database

    Is it possible to preserve and update an iphone application's database when i release an update for the application with a more updated database?

    My biggest problem to date has happened today after trying to update the Restaurant Nutrition Application. It completely crashed my iphone, and after trying to do a soft reset, NOTHING. I was able to connect to iTunes by pressing the home botton while connecting to iTunes to do a complete system restore. Everything went fine, till I tried to download some of the applications that had not been synced with iTunes with the exception of Restaurant Nutrition App. since this was the App. that crashed it in the first place. But strangely enough, when I just tried to download a simple game that I loved, (Cannon challenge), Restaurant Nutrition popped up on the screen by itself as if it was trying to download without me even requesting to do so.
    This application now has a way of attaching itself even after a system restore when you DON'T WANT IT ANYMORE!! Someone really needs to look into this. It has wasted an entire day of total frustration with my iphone, for NOW, having to do the same thing a second time. ***!? I hope come Sept. 7th, that Apple can restore customer confidence, because each time my iphone 3g crashes, which has happened several times in the past, but never to this degree, I really am beginning to hate this new iphone 3G. I can't rely on it being stable enough when I might actually have to use it......for an emergency phone call, etc.
    PLEASE update soooner!

    How do I get the weather application that is the same as the iphone application on my ipad mini?
    I don't want any other applications from the app store, I just want the regular weather app that comes with the iphones and other products.

    Apple hasn't made that particular App available for the iPad.

  • Where do I see what iPhone applications I've purchased  ?

    Well the subject says it all, Where do I see what iPhone applications I've purchased ?
    I recently restored my iPhone and now I have to download all my apps again.
    And from what I understand there is no way to see in iTunes if you've already payed for the app because it will still appear like you're buying it again until you press the buy button and when it says that you have already purchased it and wont have to do it again.
    And since many apps looks the same in icon and name I don't want to accidental purchase an app that I haven't already purchased..
    So, where do I see all my purchases?
    Thanks

    I recently restored my iPhone and now I have to download all my apps again.
    They should all be in your iTunes Library on your computer if you've been syncing and backing up your Apps regularly.
    Didn't you transfer any Apps downloaded on your iPhone to your PC before restoring it?
    So, where do I see all my purchases?
    Either in the email Receipts you got from Apple, everytime you downloaded an App, or in your iTunes Store account from within iTunes itself.
    Choose *Store > View my Account...* then click *Purchase History*
