asset-catalog

问题 I've created an iOS framework that contains a single SwiftUI View . I've then added an Asset Catalog with a single image. Trying to access that image from the SwiftUI view doesn't do anything - I see a blank image. Image("MyImage") The Xcode Preview doesn't show anything, nor does the view show anything for a test target I wrote that uses the framework. So the question is - how do I bundle images with a framework that uses SwiftUI? Is this not supported? The only way I could get this to work

问题 Does any one know how to add GIF image files to an Asset Catalog in XCode5? 回答1: Go to your Images.xcassets folder and create a folder named MyGifAnimation.xcassets, then put your MyGifAnimation@2x.gif and MyGifAnimation.gif files in it. After that, create a Contents.json file. Open that with your favorite text editor and write the following in it: { "images": [{ "idiom": "universal", "scale": "1x", "filename": "MyGifAnimation.gif" }, { "idiom": "universal", "scale": "2x", "filename":

问题 At WWDC 2017 Session 201 What's New in Cocoa Touch, around the 33:50 mark, it is stated that "By incorporating [icons] in Asset Catalogs, we're now able to have them participate in the app thinning, which will significantly lower your app's footprint. So, this is a really exciting thing to adopt, and it will be adopted by default in new projects in iOS 11. You can opt into it in existing projects by adding a key to your Info.plist." What is the key you need to add in your Info.plist to enable

问题 So according to this, you have to use imageNamed for loading images now in iOS. Unfortunately, CPTImage's constructors requires paths for loading images So something like this: [CPTImage imageForPNGFile:[[NSBundle mainBundle] pathForResource:@"plotsymbol" ofType:@"png"]] These -pathForResource calls now fail because of asset catalogs. So.. has anyone been able to do this? Did I miss something? 回答1: The CPTImage class will include an imageNamed method in a future release. It is available now

问题 In xcode 7 these is no retina 4 option, according to this, apple removed it on purpose. I did edit Contents.json to get it back but the effect is not the same! I remember in XCode6/pre-iOS9 iPhone 6 will used retina 4 picture so I only need to set one fullscreen 2x picture for iPhone 4/4s, one fullscreen Retina 4 for iPhone 5/5s and 6. I think using Retina4 for iPhone 6 really makes sense while 2x doesn't! Because 1334/750 is about 1.778, which is close to 1136/640 = 1.775 while 960/640 = 1.5

问题 I have a use case that seems to fall into the cracks between asset catalogs and size classes. My Universal app needs a full screen background image that is different in Landscape and Portrait orientations, and Landscape is only supported for the iPad & iPhone 6. Since I can't add landscape images to the asset catalog for a new image set, my current solution looks like this (supports iOS 7 & 8): // permit landscape mode only for iPads & iPhone 6 (would prefer to use size classes, but...?)

问题 I'm attempting to programmatically create an SKSpriteNode and give it a texture that is in my Assets.xcassets folder. I figured this would be a basic procedure, but I seem to be having a lot of troubles. For a reference, here is my asset catalog with the ground asset I'm trying to set to a SKSpriteNode : Here's the code to make the sprite node: sprite.texture = SKTexture(image: UIImage(named: spriteName)!) sprite.anchorPoint = CGPoint(x: 0, y: 1) sprite.position = CGPoint(x: 0, y: 0)

问题 I attributed to my .mp4 video the "tokyo" tag for example, and set it as installed during the app installation. Now before I was using a Path to get it from my resources, now it's different because it's located on the Asset Catalog. After found documentations, I tried something like : NSBundleResourceRequest(tags: ["tokyo"]).beginAccessingResourcesWithCompletionHandler { (error) -> Void in let tokyoVideo = NSDataAsset(name: "tokyo") So I can do : tokyoVideo.data to access NSData but I'm using

问题 It seems like a really easy thing to do, and in theory it looks very straight forward: create the Asset Catalog add an Image Set and name it "imageName" (without .png) add the images done or at least that's what i read pretty much everywhere, but I still can't get it to work.
