  • iPhone - how to be notified of call completion

    - by ecodan
    Hi- I'm developing an application that needs to take action on completed phone calls, preferably right after the call ends but minimally once per day. I've read up on the new CoreTelphony framework, and it seems I can get call events if my app is active, but I don't see how to launch/wake my app when a call ends if my app is not the foreground app. I also don't see how any of the new pseudo-background "modes" would allow my app to listen for these events in the background. Do any of you know how this might be done? If post-call processing isn't possible, then I'd like to figure out a way to automatically wake my app up once per day, pull all of the call events since the last wakeup, and process them. I know how I might do this with Push or Local notifications, but my understanding is that those require user action to continue; in this case, I just want the processing to happen automatically. Is there a mechanism that would enable this? Thanks, Dan

  • iPhone switching views without first view being reset

    - by user298261
    Heya! I'm making a role-playing game, and I want to have a Map View and a Battle Screen. With the possibility of other screens as well. I thought the best way to achieve this was to use multiple NIB files. When I prototyped this by have one view that creates content, switches to the next view, and then back, the content on the original view was reset. How do I make it so that the first view doesn't reset the data each time it's loaded? Thanks!

  • iPhone SDK - keep data in modal view

    - by swalkner
    Hi all, I've got a modal view loaded the following way: ModalViewController *modalController = [[ModalViewController alloc] initWithNibName:@"ModalViewController" bundle:nil]; searchController.delegate = self; [self.navigationController presentModalViewController:modalController animated:YES]; [modalController release]; When the modal view appears, "viewDidLoad" is called. When I dismiss the modal view via [self.navigationController dismissModalViewControllerAnimated:YES]; the method "viewDidUnload" ISN'T called, but the next time I let the modal view appear, "viewDidLoad" is called again. My problem now is that I'm creating an NSArray in the modal view's "viewDidLoad" - and as I'm fetching the data from the web, I would like to do it only once. But this way, it's fetched every time... Any hints how I could achieve that the data is only fetched once? I would really like to do it in the modal view and not in the parent and provide the array as parameter to the modal view... Thanks!

  • Xcode iphone sdk - Searching in UITableView, different pattern matching

    - by Lorenzo
    Hi everyone, I'm coding a UITableView with a UISearchBar to search between a list of cities (loaded in the uitableview) Here is my code for searhing: - (void) searchTableView { NSString *searchText = searchBar.text; NSMutableArray *searchArray = [[NSMutableArray alloc] init]; for (NSDictionary *dictionary in listOfItems) { NSArray *array = [dictionary objectForKey:@"Cities"]; [searchArray addObjectsFromArray:array]; } for (NSString *sTemp in searchArray) { NSRange titleResultsRange = [sTemp rangeOfString:searchText options:NSCaseInsensitiveSearch]; if (titleResultsRange.length > 0) [copyListOfItems addObject:sTemp]; } [searchArray release]; searchArray = nil;} And with this everything works fine, but i need to do something a bit different. I need to search only between items that match pattern Word* and not * Word *. For example if I search "roma", this need to match just with "Roma" or "Romania" and not with "Castelli di Roma". Is that possible with this searchbar? How can i modify this? Thanks

  • UINavigationController not working under ARC in iPhone

    - by user1811427
    I have creared a new project "Empty Application" template in Xcode 4.3, it is having only two classes AppDelegate.h & .m I cheaked with ARC to use automatic reference count while creating the app. I added two new files "RootViewController" & "NewProjectViewControllers". I implemented code to set navigation controller as follows in AppDelegate - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]]; // Override point for customization after application launch. rootViewController = [[MainViewController alloc] init]; UINavigationController *navigation = [[UINavigationController alloc] initWithRootViewController:rootViewController]; [self.window addSubview:navigation.view]; self.window.backgroundColor = [UIColor whiteColor]; [self.window makeKeyAndVisible]; return YES; } and in hte home view (Root view controller) implemented as follows - (void)viewDidLoad { [super viewDidLoad]; self.title = @"Projects"; UINavigationBar *navigationBar = [self.navigationController navigationBar]; [navigationBar setTintColor: [UIColor colorWithRed:10/255.0f green:21/255.0f blue:51/255.0f alpha:1.0f]]; //To set the customised bar item UIButton *rightBarBtn = [UIButton buttonWithType:UIButtonTypeCustom]; [rightBarBtn setBackgroundImage:[UIImage imageNamed:@"plus_new.png"] forState:UIControlStateNormal]; rightBarBtn.frame=CGRectMake(0.0, 100.0, 30.0, 30.0); [rightBarBtn addTarget:self action:@selector(addProject) forControlEvents:UIControlEventTouchUpInside]; UIBarButtonItem* rightBarItem = [[UIBarButtonItem alloc] initWithCustomView:rightBarBtn]; self.navigationItem.rightBarButtonItem = rightBarItem; // Do any additional setup after loading the view from its nib. } - (void) addProject { NewProjViewController *editProject = [[NewProjViewController alloc] init]; [self.navigationController pushViewController:editProject animated:YES]; NSLog(@"xxxxxxxxxxxxxxx"); } But since i used ARC the navigation may dealoc immediately and it doesn't work, All the actions in method works except push to the next view if i do same thing with out ARC it works fine How to resolve this issue..? Thanks in advance

  • iPhone SDK 3.0 deprecation of UITableViewCell .text

    - by djt9000
    Came across an SDK3.0 deprecation that I am having a bit of trouble tryinig to figure out. If my declaration of @property (nonatomic, retain) UIImage *rowImage; does not work, nor @property (nonatomic, readonly, retain) UIImage *rowImage; and I @synthesize rowImage; Do I need to write my own setter because @synthesize will not properly handle this? cell = [[[UITableViewCell alloc] initWithFrame:CGRectZero reuseIdentifier:RootViewControllerCell] autorelease]; // Dpericated in SDK 3.0 // //cell.text = controller.title; //cell.image = controller.rowImage; // Using what the documentation says to use Error=== cell.textLabel = controller.title; Error=== cell.imageView = controller.rowImage; Error: Object cannot be set - Either readonly property or no setter found. Hope this makes sense, any help would be appreciated.

  • Best way to display a background with a pattern in an iPhone/iPad app

    - by Dr Dork
    Here's an example of the type of background image I'm talking about... Clearly, there's a pattern in it. My question is, if this were an iPad app and the background image was twice the size, would there be any significant benefits to taking advantage of this pattern by tiling the image? Or would it really make no difference in terms of performance and just be easier to load the entire image into a UIImageView? Thanks in advance for all your wisdom!

  • iPhone - Change entity class (NSManagedObject) to make them initializable

    - by ncohen
    Hi everyone, I would like to use my custom NSManagedObject like a normal object (as well as its regular functions). Is it possible to modify the class in order to be able to initialize it like a normal object? [[myManagedObject alloc] init]; Thanks edit: to clarify the question, will it screw everything up if I change the @dynamic with @synthesize in the implementation?

  • iphone dev - how to catch exception 'NSRangeException'

    - by Brian
    In my app I try to scroll a UITableView to the top once after I updated the content of the table. However, under some circumstance, my table is EMPTY. So I got the following exception: Terminating app due to uncaught exception 'NSRangeException', reason: '-[UITableView scrollToRowAtIndexPath:atScrollPosition:animated:]: row (0) beyond bounds (0) for section (0).' how can I catch this exception? I tried NSIndexPath *indexPath = [NSIndexPath indexPathForRow:0 inSection:0]; if (indexPath != nil) { [EventTable scrollToRowAtIndexPath:indexPath atScrollPosition:UITableViewScrollPositionTop animated:YES]; } but it doesn't catch the exception because indexPath is not nil.
