I was wondering if anyone knows where I can find documentation or a tutorial on how to make a vertical tab bar for iOS like in 1Password or 2do. I figure that these aren't "real" tab bars, but I'd really like to use that functionality and I'm at a loss on how to accomplish it. Thanks in advance for any help! ...

Since the iPhone 4 came out, Apple has put forward the @2x filename technique to easily implement higher resolution pictures. That's great, but how about dynamic image downloading? Indeed, in my application I would like to avoid image scaling and unnecessary big downloads as much as possible, which could negatively impact the performanc...

Hey Guys, I am trying to use the ASIHTTPRequest libraries to simulate a form post and gather the resulting cookies; however, when I am running the post, I get an error. I have traced through the request and narrowed it down to a NSPOSIXErrorDomain error. The site I am trying to connect too is an HTTPS: site and this error makes me th...
One of my testers have ran into an issue where a UITextView would not fully render a line that is only partially displayed initially. This is on iOS 4.0.1 on an iPhone 4. In the following screenshot, the last line is Xxx TTY zzz. Only the top of the line is rendered initially, but when my tester scrolls up to see the full line, it stays...
Hey, I want to learn "Core Animation" for the iOS not for the Mac. Two books exist: PragProg: Core Animation AW: Core Animation Simplified Have you read one of them (or both)? do you have a recommendation? Thanks. ...
Assume I want to program a Star Field animation. Not by using OpenGL but by drawing directly to the screen buffer or to off-screen buffers that can be placed on screen. That Star Field demo running on the TRS-80 is of course just an example. Think video decoding or full-screen animations as other possibilities where rates of 20+ frames ...
I am trying to upgrade an older iPhone project to adopt background audio streaming, however the "Required background modes" key is not showing up in the Info.plist drop-down menu. I have set the base SDK to 4.0. Is there another project setting that governs which Info.plist keys are available? Kind regards, Rob ...
I wrote an app compiled against ios 3 that would easily allocate up to 100 mb of memory for image processing purposes. However, when that same app was compiled against the ios 4 sdk, I found that it crashed when many apps were open in the background. When I kill the background apps, the application then runs fine. I reduced the memory us...
Hello, I currently use a custom UIWindow to display a custom alert view to make it look Apple style. When I remove it, it doesn't fade automatically, sk I decided to use a UIView animation and change the alpha to 0 then remove it but that still didn't do the trick. Would you guys know what to do? ...

As far as I can tell, technically MKPolyline and MKPolygon should not be functional/available when running on an iPad or any other device prior to iOS4. Nevertheless, when I installed 3.2.2, on the device, and updated my build tools with the latest (non-beta) iOS 4.2 SDK, they both work just fine, along with their associated views. Wha...
I've been at this for hours now, and don't even know how to debug this error.

Still beavering away, slowly sorting out how things work. Today I've been looking at persistent stores and managed objects. I think I understand the basics of it all, but I've noticed something odd. When I save my managed object context and open up the resulting sqlite file in an editor, there are three tables there I don't expect. They'...
