iphone-sdk-3.0

Does anyone have a snippet that uses the AudioToolBox framework that can be used to play a short sound? I would be grateful if you shared it with me and the rest of the community. Everywhere else I have looked doesn't seem to be too clear with their code. Thanks! Here is an easy example using the AVAudioPlayer: -(void)PlayClick { NSURL* musicFile = [NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:@"click" ofType:@"caf"]]; AVAudioPlayer *click = [[AVAudioPlayer alloc] initWithContentsOfURL:musicFile error:nil]; [click play]; [click release]; } This assumes a file called "click.caf"

I have a UISearchDisplayController setup with a UITableViewController which is nested inside a UINavigationController . When a selection of a cell is made, UITableView's didSelectRowAtIndexPath method is triggered, which pushes a new view to the parent navigation controller. This new view should have the navigation bar hidden on entry. [[self navigationController] setNavigationBarHidden:YES animated:NO]; I use this line in the didSelectRowAtIndexPath method to hide the navigation bar. This works fine when a row is selected not using the search controller, but is overridden when selecting a

I have a website which sells a product to the user (downloadable). I am creating an iPhone app and want to be able to sell some of the products using the 3.0's in-app purchase. Now the documentation mentions that anything you want to sell has to be uploaded to iTunes Connect and approved by Apple. But I want to be able to keep adding products to be sold by my app on a daily basis. I have a web service to get the list of products from the website. Is it possible to include in-app purchase to let user buy this stuff from within the app but without having to add them to iTunes Connect? As I

This morning I ran into a crash in an iPhone app I am working on and while I fixed the bug, I'm curious about syntactic reason it was a problem. Here is my code reduced to simple elements. I am populating items in a TableView using an NSArray for the items. The NSArray is a property: @interface FooViewController : UITableViewController { NSArray *stuff; } @property (nonatomic, retain) NSArray *stuff; And in my implementation file: @synthesize stuff; - (void)viewDidLoad { NSArray *arr = [[NSArray alloc] initWithObjects:@"", @"Item 1", @"Item 2", @"Lorem", @"Ipsum", nil]; self.stuff = arr; [arr

I have an object, I make some changes to it, but I don't want to save them, I want the 'old' values. I've tried with: [managedObjectContext rollback]; [managedObjectContext redo]; [managedObjectContext reset]; and none of them seems to work ... NSLog(@"current: %@",ingredient.name); // ===> bread [ingredient setName:@"test new data"]; NSLog(@"new: %@",ingredient.name); // ===> test new data [managedObjectContext rollback]; [managedObjectContext redo]; [managedObjectContext reset]; NSLog(@"current: %@",ingredient.name); // ===> test new data // I want again ===> bread Should I refetch the

I know barely nothing about JSON and I need to send a request to a server and read the data coming from it, using the iPhone only. I have tried to use the jason-framework to do that, but after readin the documentations I was not able to figure out how to construct the object and send it on the request. So I decided to adapted another code I saw here on SO. The Object I need is this: { "code" : xxx } Here I have a problem. This xxx is a NSData, so I suspect that I have to convert this data to a string, then use this string to build an object and send this on the request. the server response is
