  • AVD properties for Motorola Flipout?

    - by kefs
    I'm looking to create AVDs to test my apps on, and i'm trying to figure out the correct settings for a square screen such as the new Motorola Flip Out. I don't see a wikipedia article for it, or many specs... On a related note, what about tablets? Actually.. Why aren't there a set of AVD instances with params from popular devices.. or at least a site that lists them for each of the 60+ devices. Thanks in advance :)

  • Core Data and Relationships

    - by alku83
    I have two objects, a Trip and a Place. A Trip represents a journey from one Place to another Place, ie. a Trip needs a fromPlace and a toPlace. So, this is a 1-to-2 relationship, but I need to know which is the "from" and which is the "to". I am not sure how to model this in Core Data. I have created two entities (Trip, Place), and now I want to setup the relationship(s) so I have a fromPlace and a toPlace. Do I need to add an extra field on the Place entity called isFrom, or similar? If this was in a database, I would just have a id column on the Place table, and then two columns in the Trip table - fromPlaceId and toPlaceId. How do I achieve something similar in Core Data?

  • xcode collect2: ld returned 1 exit status - how to resolve?

    - by Remover
    From what I have read this is supposed to be when the linker (not exactly sure how that works) can't find a symbol. the symbol in question is: SCNetworkReachabilityCreateWithAddress as can be seen from the full error message below. the thing is that the correct framework is added to my target. xcode recognises the symbol OK, i.e. there is no error message in the .m file. the .m file is added to the correct target so I'm not at all sure what to do. Any ideas please? "SCNetworkReachabilityCreateWithAddress", referenced from: -[AppWelcomeVC viewDidLoad] in AppWelcomeVC.o ld: symbol(s) not found collect2: ld returned 1 exit status

  • How to save objects using Multi-Threading in Core Data?

    - by Konstantin
    I'm getting some data from the web service and saving it in the core data. This workflow looks like this: get xml feed go over every item in that feed, create a new ManagedObject for every feed item download some big binary data for every item and save it into ManagedObject call [managedObjectContext save:] Now, the problem is of course the performance - everything runs on the main thread. I'd like to re-factor as much as possible to another thread, but I'm not sure where I should start. Is it OK to put everything (1-4) to the separate thread?

  • Does this have to be released?

    - by NextRev
    I've done a lot of research on when it's correct to release things, but it's all confusing to me. I think sometimes the Leaks program is off. Anyway... background is a UIImageView background.image = [UIImage imageNamed:@"greenbackground.png"]; Do I have to release background? I never alloced it and it's not set as a property, so I'm thinking no.

  • How do I push another viewController onto the navigationController from within a tabviewController?

    - by user207788
    Hi, I have a project set up using these two tutorials. http://twilloapp.blogspot.com/2009/03/how-to-embed-navigation-controller.html and the link for the second tutorial is at the bottom of the first. The tutorial is slightly outdated but I managed to get it to work as advertised. Now I want to push a new detailedView onto the NavigationController when a user touches a row in the table view. So I added this to my MyTableViewController.m file. - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { // Navigation logic may go here. Create and push another view controller. SecondViewController *detailViewController = [[SecondViewController alloc] initWithNibName:@"SecondViewController.xib" bundle:nil]; // ... // Pass the selected object to the new view controller. [self.navigationController pushViewController:detailViewController animated:YES]; [detailViewController release]; } Now when I run this project and touch a row in my table view I am getting an error: asm_Terminating_due_to_uncaught_exception IT seems to be having an issue loading the SecondViewController from nib, however I checked the detailViewController and it is not nil. I know I am missing something and it is more than likely something simple. Please help. Thanks, Bruce

  • Issues declaring already existing NSMutableArray in new class

    - by Graeme
    I have a class (DataImporter) which has the code to download an RSS feed. I also have a view and separate class (TableView) which displays the data in a UITableView and starts the parsing process, storing parsed information in an NSMutableArray (items) which is located in the (TableView) subclass. Now I wish to add a UIMapView which displays the items in the (items) NSMutableArray. Herein lies the issue - I need to somehow get the data from the (items) NSMutableArray into the new (mapView) subclass which I'm struggling with - and I preferably don't want to have to create a new class to download the data again for the mapView class when it already is in the applications memory. Is there a way I can transfer the information from the NSMutableArray (items) class to the (mapView) class (i.e. how do I declare the NSMutableArray in the (mapView) class)? Here's a overview of how the system works: App opened Data downloaded (using DataImporter class) when (TableView) viewDidLoad runs Data stored in NSMutableArray accessible by the (TableView) class And from here I need to access and declare the array from a new (mapView) class. Any help greatly appreciated, thanks. Code for viewDidLoad MapKit: Data *data = nil; NSString *ilocation = [data locations]; NSString *ilocation2 = @"New Zealand"; NSString *inewlString; inewlString = [ilocation stringByAppendingString:ilocation2]; NSLog(@"inewlString=%@",inewlString); if(forwardGeocoder == nil) { forwardGeocoder = [[BSForwardGeocoder alloc] initWithDelegate:self]; } // Forward geocode! [forwardGeocoder findLocation: inewlString]; Code for parsing data into original NSMutable Array: - (void)beginParsing { NSLog(@"Parsing has begun"); //self.navigationItem.rightBarButtonItem.enabled = NO; // Allocate the array for song storage, or empty the results of previous parses if (incidents == nil) { NSLog(@"Grabbing array"); self.datas = [NSMutableArray array]; } else { [datas removeAllObjects]; [self.tableView reloadData]; } // Create the parser, set its delegate, and start it. self.parser = [[DataImporter alloc] init]; parser.delegate = self; [parser start]; }

  • iphone core data loop array and save each

    - by Matt Facer
    I have a core data model with two tables (meal and ingredients). I am trying to save ONE meal with MANY ingredients. I have the code below which loops through an array of ingredients. I'm trying to save it, but I cannot redeclare the "entity" below. How do I do it? I've tried releasing it, but that didn't work! Thanks for any help. for (x=0;x<ingredients;x++) { NSEntityDescription *entity = [NSEntityDescription insertNewObjectForEntityForName:@"Ingredient" inManagedObjectContext:managedObjectContext]; entity.name = @"test"; } (this method does work saving ONE record out of the loop.. so that's not the problem)

  • Programatically get own Phone Number in iPhone OS 4.0

    - by sandy
    I am developing an iPhone application for jail broken phones and in this application I would like to fetch user's phone number. I have gone through the entire stackoverflow.com and found some relevant answers but all of them are obsolete and doesn't work with iOS 4.0 anymore. The most famous solution for this problem is NSString *num = [[NSUserDefaults standardUserDefaults] stringForKey:@"SBFormattedPhoneNumber"]; but as I mentioned this solution no more works with iOS 4.0 As my application is intended towards the jail broken phones and not intended the Apple app store so I am not worried about my app rejection, hence any private API will also work for me. Also please let me know if we can fetch IMSI number from SIM using any private APIs of iPhone

  • Rotation of ViewController in TabbarController

    - by hanno
    I have a custom UIViewController in a UITabbarController and want to respond to rotation events. When a rotation occurs, the tabbarcontroller and the viewcontroller get rotated. However, the view in the viewcontroller doesn't get redrawn properly: the layout doesn't autoresize and it is black on parts of the screen. The strange thing is that it works when I go to another tab and the back again to my original viewcontroller. What could possibly be wrong? I checked that didRotateFromInterfaceOrientation:fromInterfaceOrientation is being called. However, the view.frame.size values are still the old ones from before the rotation. That's probably not correct.

  • Objects do not retain the frame that I give then when using CGAffineTransforms with Core Animation

    - by user170030
    Hi, I'm making a game where when a card is touched, it grows so that it is focused, and when you 'let go', it goes back to its original size and place. This seems pretty standard, however, when I add cards and move the hand around to accommodate different numbers of cards, touching the card makes it go to its original place, and not to the new place. This has been stumping me for a while now Any hints would be much appreciated. Thanks !

  • Start one functon after another finished iphone

    - by user295944
    I have a function that updates the gps coordinate lat and long then sends a tweet with the lat and long info attached. I want the function to wait until the lat and long are filled before the tweet goes through but it seems to do both at the same time so the lat and long don't get filled in. How do I make the gps location update first?

  • How to load a NIB inside of a view in another NIB?

    - by Sheehan Alam
    I have two NIB's ParentViewController.xib ChildViewController.xib ParentViewController.xib contains a UIView and a UIViewController. ChildViewController.xib contains a UIButton I want ChildViewController.xib to load in the ParentViewController.xib's UIView I have done the following: Created @property for UIView in ParentViewController Connected File's Owner to UIView in ParentViewController Set UIViewController in ParentViewController's NIB Name property to ChildViewController in Interface Builder Set ChildViewController view property to UIView in ParentViewController I was hoping this would load ChildViewController into my UIView in ParentViewController but no luck. I did get the following warning, which could be the culprit: 'View Controller (Child View)' has both its 'NIB Name' property set and its 'view' outlet connected. This configuration is not supported. I also have added additional code in ParentViewController's viewDidLoad(): - (void)viewDidLoad { [super viewDidLoad]; ChildViewController *childViewController = [[ChildViewController alloc]initWithNibName:@"ChildViewController" bundle:nil]; childViewController.view = self.myView; } Any thoughts on why ChildViewController does not load in the UIView of ParentViewController?

  • iPhone 4.0 Screen Resolution and writing robust code...

    - by Magic Bullet Dave
    Does anyone know what will happen with existing apps when they run on the iPhone 4.0 in terms of the new screen resolution? I am assuming, just like developing for the iPad that there should be no hard coded screen resolutions in your code. I'd also like advice on the best way of writing robust code to work well on any device. For instance, detecting the screen resolution is not enough - on the iPad the screen is physically bigger so you can display more items on it. On the new iPhone the screen is the same physical size but higher resolution, so the likely thing is that you wont want to display more items, just higher resolution versions of them. Any help would be useful, Regards Dave EDIT: I have read the other similar posts, I guess what I really would like to know is what is the recommended way to write code for all App Store devices in a robust way so they a) all work b) make best use of the device.

  • CoreData NSFetchedResultsController Empty Section Display

    - by user280390
    Hello I would like to show a fixed number of sections in a table view with a Fetched Results Controller as the data source. If you image the contacts app where sections organised by the alphabet, it will not have a header for B if there are no contacts in that section, so the section headers you see are A then C. I would like to display a section header in my table (for B), but without any rows. an empty section in effect. Can NSFetchedResultsController do this for me?

  • How would I add code that would update an online "counter" so I know how many times an iPhone app is

    - by Luis Tovar
    So I have searched for this but not finding anything about it and if I missed it sorry about that. What I am trying to do is see how to go about adding some code to my iphone app that will connect to a php script (if connection available) and update a counter so that I can let my clients know that their app is constantly being used? Also, would apple allow that? Or would my app be denied for doing such a thing? Any help would be great! Thanks in advance.

  • Create an UIButton with "push button" appearance?

    - by Krumelur
    I want to create a button with the same look and feel as the "Timer" function in the builtin Clock app, but it really eludes me how to do it. By looking at the source code for UICatalog, it seems to create these buttons you need to create a custom bitmap. Is this true? If so, is there a "standard" bitmap that can be used, to ensure consistent user experience?
