如何在iOS的cocoapod库中使用图像资产目录 [英] How to use images asset catalog in cocoapod library for iOS

问题描述

我有一个cocoapod库，其中包含2种格式的资产：

I have a cocoapod library which contains assets in 2 formats:

• a .storyboard


• XCode资产目录.xcassets（带图像）

我的 podspec 文件包含资源包的定义：

my podspec file contains the definition for the resource bundle:

s.resource_bundle = {'SparkSetup' => ['Resources/**/*.{xcassets,storyboard}']}

我有一个pod项目中的单独目标通过使用这些文件+该包的plist文件来创建资源包。

and I have a separate target in the pod project to create a resource bundle by using those files + a plist file for that bundle.

当我在应用程序项目中使用pod时 - 我可以看到故事板/ xcassets文件位于pod目标中，我可以轻松访问和运行故事板，但故事板中引用的图像（到.xcassets文件）在运行时找不到（但在IB中正确显示） ）。

thing is that when I use the pod in an app project - I can see the storyboard/xcassets files being in the pod target and I can access and run the storyboard easily but the images referenced in the storyboard (to the .xcassets file) are not found in run-time (but displayed correctly in IB).

我得到的错误是：

Could not load the "spinner" image referenced from a nib in the bundle with identifier "(null)"

我确实看到了产品目录中的捆绑文件。
要在故事板中实现风险投资，我使用：

I do see a bundle file in the products directory. To instanciate VCs in the storyboard I use:

+(NSBundle *)getResourcesBundle
{
    NSBundle *bundle = [NSBundle bundleWithURL:[[NSBundle mainBundle] URLForResource:@"SparkSetup" withExtension:@"bundle"]];
    return bundle;
}


+(UIStoryboard *)getSetupStoryboard
{
    UIStoryboard *setupStoryboard = [UIStoryboard storyboardWithName:@"setup" bundle:[SparkSetupMainController getResourcesBundle]];
    return setupStoryboard;
}

这似乎很适合查找故事板，但不适合查找图片同一捆绑中的.xcassets。

which seems to work well for finding the storyboard, but not for finding images in the .xcassets in the same bundle.

我做错了什么？如何从这个故事板/代码中引用图像，并能够将此UI pod集成到任何应用程序中？

What am I doing wrong? how can I reference images from this storyboard/from code and be able to integrate this UI pod into any app?

谢谢！

推荐答案

至少从Cocoapods版本1.0.1开始，支持图像资产目录。

At least as of version 1.0.1 of Cocoapods, image asset catalogs are supported.

在我的Swift中代码，我用过：

In my Swift code, I used:

public static var GoogleIcon:UIImage {
    let bundle = NSBundle(forClass: self)
    Log.msg("bundle: \(bundle)")
    return UIImage(named: "GoogleIcon", inBundle: bundle,compatibleWithTraitCollection: nil)!
}

在我的pod规范中，我使用了：

In my pod spec, I used:

s.resources = "SMCoreLib/Assets/*.xcassets"

当我使用模拟器构建时，.car文件 显示在框架中：

When I build using the simulator, the .car file does show up in the Framework:

cd /Users/<snip>/SMCoreLib.framework 
ls
Assets.car  Info.plist  SMCoreLib
