Hi. I have a button with an image set through interface builder. The original image is SearchImage.png and the high rez version is [email protected]. I'm absolutely sure that no typos were made, and the higher resolution image is indeed exactly twice the size (ie twice as tall, twice as wide) as the lower resolution image, yet the offi...
So far I haven't been able to find the specifications for the iPhone screenshots we'll submit along with our application. (It's universal, so I'm also taking iPad screenshots.) Can they / should they be of iPhone 4 resolution (640x960 instead of 320x480)? ...
I would like to build an app for the iPhone which uses Skype service with more features. Now I know that Fring made Skype calls available on the iPhone, so it must be feasible. The question is, how to build it in a way that it'll work as same as Skype app or Fring. In this blog post, that guy offers using "SoonR Talk", but The caveat...
So supposedly in the iOS 4 SDK you can edit and write to the user's iTunes library. I can successfully load an AVAsset from my iPhone/iPod library, but as a quick test I'm trying to just overwrite the same file right away using AVAssetExportSession but it's always returning the status "4" which I THINK is AVAssetExportSessionStatusFailed...
I thought I read/saw/heard something saying that apps built for iPhone 4's Retina Display would automatically run at 640x960 when installed on an iPad. However, can't find any documentation on that specific feature, and my app still runs at 320x480 when installed on an iPad. Is there a step I've missed to make this happen? Or did I jus...

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...

I have a chart drawn with CoreGraphics. This chart can be scrolled horizontally and it's drawn as we scroll it. The problem is that on 3G/3GS the speed and performance of the scroll is good but on iPhone 4 is slower than expected. I suppose this is a issue related to the higher resolution of the iPhone 4. Is that correct? How can I i...
I want to do an iPhone 4 only app that uses the iAd AdBannerView. When I add this it has a fixed size of 320x50. How does this work with the higher resolution? Can someone explain how the higher resolution of the iPhone4 vs the previous devices work in relation to UIView's in xib files. Do I create the UIView with the higher resolution ...

hi, I am actually doing some daily checks of the app assuming the app will be closed and opened daily. It works fine for 3.1 devices.

For our iPhone app, we are using 50 x 50 user image (from facebook). It works fine for iPhone 3G and 3GS but not for iPhone 4 due to its high resolution display. For iPhone 4 we tried to send 100 x 100 (variable height) image but it is not working for obvious reasons. Any thought? ...
I am creating a lot of webviews that must be compatible with both the iPhone 4 retina display and pre-iPhone 4 devices. It's a pain in the ass to export multiple files for each image. Is there a script or utility to automate this process? ...
Am I missing something about the @2x graphics on the iPhone 4? I'm running the 4.0.2 SDK in the iPhone Simulator, but UIScreen has a scale of 1.0, isn't it supposed to be 2.0 and load high res images automatically? here's what's I'm testing: NSLog(@"system version: %@", [[UIDevice currentDevice] systemVersion]); NSLog(@"scale factor...
This has been asked multiple times here, but without a solid and understandable answer. This is a web-app, not a native-app. I'm using: <link rel="apple-touch-startup-image" href="images/startup.png" /> to display the startup image. It loads fine if the image's resolution is 320x460. I tried using the retina's resolution which is 640...
