I am working on an app that will have images showing golf course holes. I want the images to fill the iPhone screens, but how do I differentiate between iPhone4 and iPhone5 so the image work with both screens? I don't really want them to be squished up to fit onto a 4, or stretched to fit to a 5. I'd rather provide both size images and somehow have the phone use whichever's appropriate. thanks!

iPhone 4 = 640 x 960, iPhone 5 = 640 x 1136. If you want to achieve this without stretching an option you may want to have a look at is doing all of your artwork to fit the iPhone 5, make your artwork so that the 176 pixels on the bottom of you iPhone 5 artwork don't look odd when they are missing off the bottom of the iPhone 4 screen. (I.e. not having crucial text or logos in that area, otherwise they will be missing off the bottom of the iPhone 4 screen). Photoshop: "Save for Web and Devices" Option is the one to choose, then set the correct resolution. :) not got Photoshop? Check out http://www.splashup.com -Nick

yep, thanks. I thought of that, but would have preferred not to do it that way. I guess it's the easiest!

If you were to do it purely in Xcode then obviously you could just have two different sets of artwork... someone may have a work around to code in but it will be laborious. If apple were to have made the iPhone 5 like 816 x 1136 that would have been nice of them.

Create two versions of your images, one sized for iPhone 4 and one for iPhone 5. Name the iPhone 5 version with an extension of "[email protected]" and iOS will pull the correct image automatically. For instance: 320x480 = "background.jpg" 640x960 - "[email protected]" 640x1136 = "[email protected]"

It's not laborious in code actually. Just get the size of the screen and display the proper image using either an if/else statement or a switch/case

Or what MGOBlue said :)

This doesn't work for me... I've just uploaded a file called "home.png" in BT CP and I've made another called "[email protected]" and popped then both into the xcode project... nothing happens.

You can get the device's height and width like this: int Width = appDelegate.rootApp.rootDevice.deviceWidth; int Height = appDelegate.rootApp.rootDevice.deviceHeight; (assuming you have initialized the appDelegate in your method before declaring the above variables.) For distinguishing between iPhone 4 & 5, all you'll need is the height. Are you trying to add the picture to a plugin already in use, or a new screen/plugin you're working on?

A new one ... :)

Good. Then you should be able to do something like this: //replace "BT_appDelegate" with the name of your appDelegate file BT_appDelegate *appDelegate = (BT_appDelegate *)[[UIApplication sharedApplication] delegate]; //get device height int Height = appDelegate.rootApp.rootDevice.deviceHeight; //define image name in a string variable NSString *theImage = @"home.png"; if (Height > 480) { //we are an iPhone5 theImage = @"[email protected]"; } //set the image someImageView.image = [UIImage imageNamed:theImage];
