Hi, I'm looking to create an interface where the user can navigate through large volumes of images. Each image has a thumbnail of 128x128 that I wish to display and will be kind of similar to coverflow in operation. I have this all working in principle but am becoming stuck when navigating through content at speed. The interface begins ...

However, using this code: Event *lists = (Event *)[eventList objectAtIndex:indexPath.row]; accessStatement = "select * from DatabaseName"; [self findEvents]; // Code that b...
My app has a SQLite database that users can read only. I, the developer, would like to add entries to the database from time to time and make the enlarged database available as a file on a Web server. I'd like the users to be able to "check for updates". My question is, once a user checks and finds that an updated DB file exists, how ca...
I have designed a view with a toolbar that appears modally in Interface Builder. I have a UIBarButtonItem that is on the left hand side, which I would like to appear on the right hand side of the toolbar. How can I do this in IB, or via code? ...
Hi there, I wonder if it is possible to build iphone-wireless' stumbler app with Apple XCode or it is necessary to use alternative arm-apple-darwin environment to build it. thanks ...
The UIAlertViewDelegate protocol defines two methods, alertView:clickedButtonAtIndex: and alertView:didDismissWithButtonIndex:, which seem to me to be identical in usefulness. Why is there a clickedButtonAtIndex and a didDismissButtonWithIndex when they both do the same thing? I realize there is also a willDismissButtonWithIndex that ...
This may not be a programming question, but I don't know where to ask for this and it's still related. We all know that the checkbox and drop-down menu is a UI paradigm brought in from HTML or web interface. I'm not asking for code implementations here. A google search had produced many results. Although if anyone is willing to share ...
hi Guys, I would like to increase the height of a UIImageView with every animation frame using Core Animation. Is there any way to do this? I have done this using an NSTimer. I set the UIImageView contentMode to scalingMode and then with each tick of the timer i was incrementing the height. Is there a cleaner, high level way of doing t...
I used core data to do this: NSManagedObjectContext *m = [self managedObjectContext]; Foo *f = (Foo *)[NSEntityDescription insertNewObjectForEntityForName:@"Foo" inManagedObjectContext:m]; f.created_at = [NSDate date]; [m insertObject:f]; NSError *error; [m save:&error]; Where ...
Maybe it's just the fact that I've been using http://nodejs.org/ lately, but the lack of closures in Objective-C (iphone) has been really hard to work around. For example, I'm creating service classes. Each service class can have several methods, each of which makes a different URL request. I can use the delegate pattern, but that mean...
I tried everything to debug this one but I can't get to the bottom of it. This code lives in a subclass of NSOperation which is processed from a queue: (borders is an ivar NSArray containing 5 UIimage objects) NSMutableArray *images = [[NSMutableArray alloc] init]; for (unsigned i = 0; i < 5; i++) { CGSize size = CG...
Hi everybody, I'm trying to create a new contact and add it to the AddressBook but when I get to the ABAddressSave line of code I get EXC_BAD_ACCESS. I cannot see what am I doing wrong, I enabled NSZombie to check if this is a memory related error but it didn't spot any. Can anybody tell me what is wrong with this code? Thank you in adva...
I want to change an image on a view, from a popup dialog of 4-6 icons (imagine like changing your image on a messenger application). The way I implement this modal popup is by creating a new view at IB, with opacity on the background, and then I load this as a subview: IconsViewController *iconsViewController = [[IconsViewController...
There is information that is only available after drawRect that I need to access when loading a UIView. Is there any way to do a "pre-draw" or offscreen in order to get this information earlier? ...
Hi! I made a toolbar with two buttons on it. I then created two outlets in my class controller. Then I hooked the the controller to the buttons and selected the outlets. Finally I rewritten the class files (that added: IBOutlet id next; IBOutlet id previous; to my .h file). So now, everything looks okay. But then I try somewhere in...
I started my iPhone application as a navigation-based app which has served me well until now. In the nib for my TableViewController, I see the TableView (with its example values of California cities) but I'm able to drop any other UI elements on it (for example an UILabel). I can add a UIWindow which gives me a separate window to add st...
This has been annoying me for a while in several XCode projects. I really don't like to have compiler warnings when I build. When I build my current project, I get the following warning from a bunch of XIB files: /.../CaseInformationView.xib:3:0 UIScrollView's 'Bounce Zoom' option will be ignored on iPhone OS versions prior to 2.1. ...
Hi guys, I have a core data-based app that manages records of auto dealerships. Each record stores the dealer's address, which is broken into addressLine1, addressLine2, city, state, and zip components, each stored as a string in the data store. I would like to present a list of cities with dealerships to the user, so I'm trying to fi...
