  • 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?

  • 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

    - by alecnash
    Guys I am a little bit stuck here. So here it goes. I am using json to get latitude and longitude for a map project. I use these values to add some pins on the map. I also created a detail view for the pins. Here comes the tricky part. I want to load some images from my db to the detail view but I don't know how to tell the pins appart so the right image goes to the right pin. Thanks in advance

  • iPhone - Image overlay MapKit framework?

    - by Peter
    I can see with iOS4 you can now tile an image on google maps (Been looking at the TileMap example from apple). This is great as this is what I want to do, but from what I can see I need to know the GEO reference of the image so I can raster the images with the appropriate zoom levels, etc. What I have is an artist image, which is a map of a specific area and I want to overlay this image on google maps. Am I missing something here, but can this be done with a none standard map and having different zoom levels? The main reason why I need to use google maps is because of the GPS functionality, so the user will know where they currently are on the map.

  • iPhone crashing when presenting modal view controller

    - by Michael Waterfall
    I'm trying to display a modal view straight after another view has been presented modally (the second is a loading view that appears). - (void)viewDidAppear:(BOOL)animated { [super viewDidAppear:animated]; // Show load LoadViewController *loader = [[LoadViewController alloc] init]; [self presentModalViewController: loader animated:NO]; [loader release]; } But when I do this I get a "Program received signal: "EXC_BAD_ACCESS"." error. The stack trace is: 0 0x30b43234 in -[UIWindowController transitionViewDidComplete:fromView:toView:] 1 0x3095828e in -[UITransitionView notifyDidCompleteTransition:] 2 0x3091af0d in -[UIViewAnimationState sendDelegateAnimationDidStop:finished:] 3 0x3091ad7c in -[UIViewAnimationState animationDidStop:finished:] 4 0x0051e331 in run_animation_callbacks 5 0x0051e109 in CA::timer_callback 6 0x302454a0 in CFRunLoopRunSpecific 7 0x30244628 in CFRunLoopRunInMode 8 0x32044c31 in GSEventRunModal 9 0x32044cf6 in GSEventRun 10 0x309021ee in UIApplicationMain 11 0x00002154 in main at main.m:14 Any ideas? I'm totally stumped! The loading view is empty so there's definitely nothing going on in there that's causing the error. Is it something to do with launching 2 views modally in the same event loop or something? Thanks, Mike Edit: Very strange... I have modified it slightly so that the loading view is shown after a tiny delay, and this works fine! So it appears to be something within the same event loop! - (void)viewDidAppear:(BOOL)animated { [super viewDidAppear:animated]; // Show load [self performSelector:@selector(doit) withObject:nil afterDelay:0.1]; } - (void)doit { [self presentModalViewController:loader animated:YES]; }

  • Enable/disable zoom on iPhone safari with Javascript?

    - by msqr
    I have 1 page which has 2 DIV elements which is shown/hidden based on user click on action buttons with javascript, I would like to toggle scaling on action button click. I tried with below javascript and it is changing viewport meta but getting no effect. Any suggestions? Blockquote var ViewPortAllowZoom = 'width=device-width;'; var ViewPortNoZoom = 'width=device-width; initial-scale=1.0; maximum-scale=1.0; minimum-scale=1.0; user-scalable=no;'; function AllowZoom(flag) { if (flag == true) { $('meta[name*=viewport]').attr('content', ViewPortAllowZoom); } else { $('meta[name*=viewport]').attr('content', ViewPortNoZoom); } }

  • 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!

  • Three20 Library Cannot find its own headers Xcode iPhone

    - by DieLaughing
    import "Three20/Three20.h" Fails. Go download it and build a sample app. If that works, then make a new app from the templates provided, then watch as it fails spectacularly to find the right HEADER_SEARCH_PATH. 1) I've gone to the info page for the TARGET and not the PROJECT (Well, I tried both) and tried a bunch of different paths for the HEADER_SEARCH_PATH field. 2) I've tried dragging and dropping the dependent files from the finder and COPYING or just referencing both fails. (RANT: WTF?! Really? I wish public code libraries saved me time ONCE in my life.)

  • iPhone: Cocos2d how to make a sequence

    - by Johannes Jensen
    I have two logos, which I want to come in after each other. I'd like to use CCFadeIn and CCFadeOut. I have Logo1, and then I want it to CCFadeIn, then I want it to stay for 2 seconds, then make it fade out using CCFadeOut, and then make Logo2 CCFadeIn for 1 second, stay for 2 seconds and then go away during 1 second with CCFadeOut. How I would make this I'm not completely sure. I can't seem to find a way to make a CCAction fire a method (let's say -finishedFadingInLogo1:), so I don't know how to do this. Any ideas?

  • noob iPhone "count" frustrations!?!?!

    - by codemonkey
    Okay, I know I must be doing something incredibly stupid here. Here's the sample code (which, when executed within a viewDidLoad block silently crashes... no error output to debug console). NSMutableArray *bs = [NSMutableArray arrayWithCapacity:10]; [bs addObject:[NSNumber numberWithInteger: 2]]; NSLog(@"%@", [bs count]); [bs release]; What am I missing? Oh... and in case anyone is wondering, this code is just me trying to figure out why I can't get the count of an NSMutableArray that actually matters somewhere else in the program.

  • UITableView cell appearance update not working - iPhone

    - by Jack Nutkins
    I have this piece of code which I'm using to set the alpha and accessibility of one of my tables cells dependent on a value stored in user defaults: - (void) viewDidAppear:(BOOL)animated{ [self reloadTableData]; } - (void) reloadTableData { if ([[userDefaults objectForKey:@"canDeleteReceipts"] isEqualToString:@"0"]) { NSIndexPath *path = [NSIndexPath indexPathForRow:0 inSection:8]; UITableViewCell *cell = [self.tableView cellForRowAtIndexPath:path]; cell.contentView.alpha = 0.2; cell.userInteractionEnabled = NO; } else { NSIndexPath *path = [NSIndexPath indexPathForRow:0 inSection:8]; UITableViewCell *cell = [self.tableView cellForRowAtIndexPath:path]; cell.contentView.alpha = 1; cell.userInteractionEnabled = YES; } if ([[userDefaults objectForKey:@"canDeleteMileages"] isEqualToString:@"0"]) { NSIndexPath *path = [NSIndexPath indexPathForRow:1 inSection:8]; UITableViewCell *cell = [self.tableView cellForRowAtIndexPath:path]; cell.contentView.alpha = 0.2; cell.userInteractionEnabled = NO; } else { NSIndexPath *path = [NSIndexPath indexPathForRow:1 inSection:8]; UITableViewCell *cell = [self.tableView cellForRowAtIndexPath:path]; cell.contentView.alpha = 1; cell.userInteractionEnabled = YES; } if ([[userDefaults objectForKey:@"canDeleteAll"] isEqualToString:@"0"]) { NSIndexPath *path = [NSIndexPath indexPathForRow:2 inSection:8]; UITableViewCell *cell = [self.tableView cellForRowAtIndexPath:path]; cell.contentView.alpha = 0.2; cell.userInteractionEnabled = NO; NSLog(@"In Here"); } else { NSIndexPath *path = [NSIndexPath indexPathForRow:2 inSection:8]; UITableViewCell *cell = [self.tableView cellForRowAtIndexPath:path]; cell.contentView.alpha = 1; cell.userInteractionEnabled = YES; } } The value stored in userDefaults is '0' so the cell in section 8 row 2 should be greyed out and disabled, however this doesn't happen and the cell is still selectable with an alpha of 1... The log statement 'In Here' is called so it seems to be executing the right code, but that code doesn't seem to be doing anything. Can anyone explain what I've done wrong? Thanks, Jack

  • iphone app hangs in AppDelegate (?)

    - by d_CFO
    No nib/IB, so I've inserted "myAppDelegate" in main and deleted the reference to main.xib in info.plist. Debug continues nicely through all five tab controllers; they seem to have gotten properly loaded into the nav controller. In fact, control passes out of the last "}" in applicationDidFinishLaunching. But there was no (visible) response back at [window addSubview:[tabBarController view]]; and [window makeKeyAndVisible]; statements, much less to the loadView within the first tab (program execution never gets there). The last line is, UIApplication _performInitializationWithURL:sourceBundleID:]. I missed a step? I executed a step improperly?

  • reloading a table view with an Iphone app

    - by ajaywillis
    I am using a table view controller that makes a call to a web service and then parses the XML and display it in the table view. The problem is that the first time that I load it the XML apparently is not finished parsing before the view is shown. How can I reload the view after the XML is done parsing?

  • 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.

  • 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
