在iOS框架中找不到纹理图集

Question

在我试图将我的资产(雪碧表)放入iOS框架之前，每件事情都很正常。我在使用Swift 3.0

为了减轻我的Xcode项目，我决定把我的资产:由TexturePacker生产的雪碧片放在一个框架中。当它们包括在主要项目中时，作为内部资源来源，一切都很好。但是当我把我的地图集放在一个框架里时，代码编译的很好，没有错误，这个应用程序在物理设备(一个iPad)上运行的很好，但是我有一个红十字会而不是我的精灵。我从控制台获得以下错误消息：

2016-11-02 15:35:02.166测试难题310:42458纹理地图集“统计”找不到。2016-11-02 15:35:02.392测试难题310:42458纹理地图集'Puzzle0‘找不到。2016-11-02 15:35:02.393测试难题310:42458纹理地图集'Puzzle1‘找不到。

等(直至41岁)

我已经将public关键字放在了我的类和所有从主项目调用的函数之前。举个例子..。

public class Statiques {

}

在我的主要应用程序中，我用以下代码调用框架：

import Foundation
import SpriteKit
import AVFoundation
import Framework_Dancing


class GameScene1: GameScene {

// not useful code for this problem is missing here...

let sheet = Statiques()

let sprite_dancing1 = SKPuzzleAnim(texture: sheet.Dancing1())
let sprite_dancing2 = SKPuzzleAnim(texture: sheet.Dancing2())

我的框架是130 MB，让我认为它中包含了正确的资产，我没有从编译器那里得到错误，我缺少了什么？一旦我把资产放到主项目中，没有了框架，一切就都好了。

所有的地图集都是由TexturePacker制作的。

下面是我的Xcode项目的屏幕副本和框架中的代码：

谢谢你的帮忙,

Answer 1

以下是我从TexturePacker的创建者那里得到的答复：

据我所知，SKTextureAtlas构造函数总是在主应用程序中搜索它的地图集文件，即使它是在框架代码中调用的。我不知道这是一个bug还是一个特性，你必须问一下苹果。对不起，但我不能帮你解决这个问题:-/问好，Joachim

Answer 2

我相信您会发现错误，因为您正在寻找主项目中的资产，而不是框架项目中的资产。

例如，如果要显示存储在框架中的UIImage，则必须编写以下代码

let image = UIImage(named: "SomeImage", in: Bundle(identifier: "FrameworkBundleID"), compatibleWith: nil)

你可以在这里读到更多关于这个的内容。

问题是SKNode/SKSpriteNode等没有类似的初始化器，所以我不确定它是否会工作。

希望这能有所帮助
