Not immediately seeing where to download legacy versions of the iphone SDKs. I can get the latest 3.1.3 release and 3.2 betas off the Apple developer site, but a lot of example code I'm finding online was written for 2.0-2.2 and it is still relevant code, but I can't build them because I don't have the 2.0-2.2 SDK. Thanks! ...
I would like to begin work on an iPhone app that does little more than display a books content for reading. The book content is available online, and is fully open source, but I would like to make the content available locally. With apps that I have worked on previously, namely with iPhone OS 2.X, creating (or finding) an .sql database a...
Hi. I'm trying to create an application in interface builder, and I'm having a problem. What I want is to create a screen with an image, together with a sectionIndexTitlesForTableView bar.

I was wondering how I can use the Amazon Search API in my iPhone app code. I've looked around and can't really find any good usage examples. My idea would be the lookup of a certain, specific Amazon product and the ability to let the user buy that item. Thanks. Any help would be great! Update: I didn't mean ordering. I just mean the ...
Can anyone point me in the right direction on how I would minimize ambient noise while recording someone speaking using the iPhone SDK Core Audio? I'm guessing a band-pass filter that eliminates any frequencies above and below the human vocal range might work. I have no idea how I would implement band filters on audio in the SDK though. ...

I'm having trouble getting components added through the Interface Builder to work on the iPhone. It works perfectly in the simulator, but not on the device. When debugging I found that the events are handled on exit, instead of when i actually press the button. Anyone else run into this issue? edit: after some investigation, it turns ou...
I just started getting into iPhone development. I have been mish-mashing tutorials and material from books in order to get my bearings straight. I come from a PHP and Java background... Objective-C is a bit quirky. But, I learn best by getting my feet wet. Basically, I have these actions. getPhoto is bound to a couple of UIBarButtonItem...

The first time I load the text field and use the keyboard, everything works normally. The second time I use it, the typed text does not show in the text field. However, the t...

Exemple: [self.navigationItem.rightBarButtonItem.accessToMySegmentedControl setEnabled:NO ...]; Cheers mates, Gauthier ...
I see a lot of objective-c code that just #defines local constants it needs, and then proceeds on its merry way. The problem is that, as far as I know, #defines aren't scoped. Many of this is in Apple's own example code. For example, in the TableViewSuite example 5, the drawRect function in TimeZoneView.m contains the following block:...
