如何在VS2017 for Mac的Xamarin iOS中按Target选择对应xcassets

Got it, let’s walk through how to set this up—this is totally doable, just a bit different from Xcode’s workflow. Here’s how to replicate that target-specific asset behavior for your Xamarin.iOS project:

Step 1: Create Separate XCAssets Catalogs #

• Right-click your Xamarin.iOS project > Add > New File
• Pick iOS > Asset Catalog from the template list, name it something like CustomerAImages.xcassets (repeat this for every customer/target you need)
• Add your unique images to each catalog—feel free to use identical image names across catalogs since they’ll be tied to different targets

Step 2: Assign Target Membership to Each XCAssets #

This is the critical step that mirrors Xcode’s target selection:

• In the Solution Explorer, select one of your xcassets catalogs
• Open the Properties Pad (if it’s hidden, go to View > Pad > Properties)
• First, confirm the Build Action dropdown is set to BundleResource—this ensures the assets get bundled with the app
• Expand the Target Membership section (it might be collapsed by default)
• Uncheck all target boxes except the one this catalog belongs to. For example, CustomerAImages.xcassets should only have the CustomerATarget box checked, and same logic applies to other catalogs.

Step 3: Use Images as Normal #

• Reference images in your code just like you usually would (e.g., UIImage.FromBundle("Logo"))
• When you build a specific target, only the xcassets catalog marked for that target will be included in the app bundle—so the correct image loads automatically.

Quick Troubleshooting Tips #

• If images don’t show up, double-check the Target Membership settings—this is the most common misstep
• Ensure every xcassets has a build action of BundleResource (not None or any other option)
• Clean and rebuild your solution after adjusting target membership to make sure old assets are cleared from the bundle
