问题 The website I'm working on can be seen here. If you check out the 'About' or 'Contact' section on iPad 3 or iPhone 4 the background looks all crazy pixelated.

问题 So some iPad in the future is probably going to have Retina Display. And Apple is most likely going to stick to the @2x paradigm. I've been expecting this for awhile and so I already have @2x artwork for iPad in my apps; some are already in the app store. My question is this: Will I need to recompile and/or resubmit apps to use said artwork when this mythical iPad is released for it to take advantage of these files? Or is this something baked into the OS itself and it should just

问题 In Cocoa application I've got 16x16 and 32x32 @2x version of an image: . When the image is displayed in NSImageView Mac OS X always picks higher-resolution version (i.e. downscales the @2x image on non-retina displays instead of using the 1:1 version). (IB on the left = good, running app on the right = downscaled mess) Of course I've got both images added to the project (as image.png and image@2x.png ). If I delete the @2x image from app bundle then OS X will display the lower-resolution

问题 The way UIImageView autorotates some images and not others (or autorotates images at all) completely baffles me and I can't find the settings to turn off this autorotate behavior.

These

问题 I want my app to run on Retina devices only. How do i disable supporting non-Retina iPhone? Is that possible? 回答1: As the screen size is same for iPhone 3G, 3Gs, 4, 4S; You won't be able to find out which one is retina display among them (AFAIK).

问题 I have got a GLKView, where I try to draw a couple of cubes and I create textures from a view and map them onto the cubes. However, when I start the app on a retina device, the textures are correctly sized but they look terrible. I have tried to set the contentScaleFactor of the GLKView to the scale of the main screen - to no avail. I have also tried to multiply the the buffers dimensions by the scale, which resulted in textures that looked crisp, but were only 1/4 of the original size...
