ios image retina-display
I have set of images with @2x counterparts, but @2x arent the exact size they should be. The 2x are smaller than they should be. Width or height is smaller by 1px or 2px.Images are sliced UI which is tightly fitted.Is there something to worry about? Can this cause problems on retina like unexpected spaces?

Since including non-retina images is such a time sink, I thought I should ask… What are some pros and cons of not having non-retina images in your apps? Is the downsizing the Apple does inferior to the usual downsizing that Photoshop does?

graphics antialiasing retina-display
Conceptual question, just out of curiosity:What is less taxing on the graphics processor: Anti-aliasing (2x? 4x? Higher?) on a typical desktop machine (around 120-150dpi) or to drive a hi-density (>300dpi) screen without anti-aliasing? This question could pertain to both desktop systems and embedded (smartphones). I’m interested to see the responses!

iphone xcode ios-simulator retina-display
I have an iPhone Xcode project that currently only contains images for retina display (twice the size as normal and with a @2x.png suffix). When I run the app on the iPhone Simulator (non retina) the images are still being displayed. Does this mean I don’t need to worry about including two sets of images: retina and non-retina?This all seems a bit odd. I would assume that no images would appear on a non retina device if there are no non-@2x files included.Note: I have not tested my app on a non

I’m having difficulty dynamically drawing a reflection of a UIImage at Retina resolution (2x scale). Apple’s sample code for drawing reflections was never updated to take advantage of the higher resolution. Is there an easy solution?

ios cocoa-touch interface-builder retina-display
How can I in a right way work with pixel dimensions in Interface Builder? E.g i have an image mockup where all dimensions and sizes in pixels : “this button has margin from the left – 30 pixels e.g. and this textfield is 100 pixels long and so on”.So if I develop for Retina i need to set margin 60 pt or not? And in IB there are only Retina 3.5 and Retina 4 and there is no non-Retina. So what is a right way to handle retina and non retina screens in IB?How to correctly set dimensions for UI eleme

I have two button images, say “myButton.png” and “[email protected]” in my app’s bundle resources. At run time, I load the image using [NSImage imageNamed:@”myButton”] and need to split it into three slices and create three NSImages to use in NSDrawThreePartImage() function.The problem is that each slice NSImage needs to be multi-resolution, so that the system could pick the right resolution dynamically, as it would automatically do with the original whole image.How do you create the automatic mul

Given a Cocoa application which runs on Mac OS X 10.7 and later:What is the best way to check, at runtime, if your app is currently running on a Mac with at least one retina display attached?If checking for this sort of thing is just really wrong-headed, I fully welcome a well-reasoned explanation of why (and I will up-vote such answers if they are good).But I’d still like to know :).It seems likely you could just do a check specifically for the new Mac Book Pro “Retina” hardware (the only Mac w

background cocos2d retina-display shared-cache
I’ve a background in my app, but clicking on a button should change it and use a different one.I cannot add all of them in the sharedTextureCache because each one has a size of >16MB in the cache, and I’ve 30 different backgrounds.What’s the best way for switching the background without a loading time? I don’t want the user to wait when clicking that button.Thanks

iphone objective-c ios memory-management retina-display
I am developing a game for a company. Right now we are coming across a problem. Our game is made for the iphone and ipad. We have both regular images and @2x images. Our game works perfectly fine on iphone 3gs and all the ipad versions. But our game crashes on iphone 4 and 4s. Is it crashing because its retina? I know all the images are 4x. We are now wondering what kind of ways it can crash. Can anyone help me out here?EDIT:our game uses UIKit, cocos2d and uses OpenGL

javascript ipad uiwebview opacity retina-display
I’m developing a web application which is basically loading a UIWebView with locally stored HTML and JS files.There is a single HTML page with multiple <div> elements which correspond to different content and are shown/hidden by changing class using .addClass() and .removeClass() jQuery methods.This works fine in iPad 2 but crashes with memory warning on iPad 3.On investigation I found that changing the opacity property is triggering the crash.Shown below are the two classes that I’m using

iphone retina-display iphone-5
I have a doubt about iphone 5 resolution, seems that xcode 4.5 has added a new view size type name “retina 4 full screen” (it’s on attributes inspector). If I try to use this resolution to a view and run it on the iphone 5.1 simulator, it crashes.so, is there a way to develop to iphone 5 having support to iphone 4 or before?the console message says: * Terminating app due to uncaught exception ‘NSInternalInconsistencyException’, reason: ‘The NIB data is invalid.

I’m planing to create a blog and I’m thinking about how to serve images in the best possible quality without affecting loading times for mobile devices too much.My content column is aprox. 768 display points wide and I’m posting screenshots using a retina Macbook so the images will be at least 1500px wide. Other Retina/HIDPI users should see the version best for them. Is there a recommended best practice for this case? I’m talking only about content images (<img />); no CSS backgrounds. A
