ipod-touch

I've reproduced this on two separate iPod touch devices running iOS 6. iPhone does not seem to be affected, neither is iPad. I'm using a sprite file for images in my web application. I am now trying to provide retina support, so I have created a separate retina sprite file which is twice the dimensions of the low quality one. It seems like neither Chrome nor Safari like to display this. I'm doing the following: .img { background: url(xx-retina.png) no-resize top left; height: xx; width: xx; display: block } And in the body: <div class='img'/> The type of tag doesn't matter. The background

We have an offline Safari application with UI designed for vertical use (pixel perfect). We would like the UI to stay vertical no matter what how the user rotates the ipod / iphone. Is it possible with offline Safari application? This question is exactly the same as Can I prevent mobile safari from auto-rotating the screen on ipod touch or iphone? . Yet - the referenced question has no definite answer and has been prematurely accepted. I'm not aware of any way to prevent the rotation if it needs to run in Safari rather than a native app with an embedded UIWebView. While you can't prevent the

Is this the proper way to detect which device a user is running? NSString *currentModel = [[UIDevice currentDevice] model]; if ([currentModel isEqualToString:@"iPhone"]) { // The user is running on iPhone so allow Call, Camera, etc. } else { // The user is running on a different device (iPod / iPad / iPhone Simulator) disallow Call. } It is not a general solution but Apple in many cases provides API calls to check wether specific feature is supported or not. Examples could be: +isSourceTypeAvailable: and +availableMediaTypesForSourceType: in UIImagePickerController allowing you to check if

I'm looking for a way to differentiate at runtime between devices equipped with the new ARM processor (such as iPhone 3GS and some iPods 3G) and devices equipped with the old ARM processors. I know I can use uname() to determine the device model, but as only some of the iPod touches 3G received a boost in their ARM processor, this isn't enough. Therefore, I'm looking for one of these: A way of detecting processor model - I suppose there's none. A way of determining whether ARM neon instructions are supported - from this I could derive an answer. A way of determining the devices total storage

Could someone please tell me how to make an image appear when the user taps the screen and make it appear at the position of the tap. Thanks in advance, Tate UIView is a subclass of UIResponder , which has the following methods that might help: -touchesBegan:withEvent: , -touchesEnded:withEvent: , -touchesCancelled:withEvent: and -touchesMoved:withEvent: . The first parameter of each of those is an NSSet of UITouch objects. UITouch has a -locationInView: instance method which should yield the position of the tap in your view. joemama8933 You could create an initial star and just move it every
