We have a local html to show in UIWebView. And there, we want to show images that are defined in Asset Catalog.
I know that we can do similar thing if we had the image flat in the main bundle. The code snippet would be like this.
webView.loadHTMLString("<img src='target_image.png'/>", baseURL: NSBundle.mainBundle().bundleURL)
However, I am not sure what I can specify for "target_image.png" if the png file is packaged in asset catalog. (Furthermore, we want to specify pdf to take advantage of vector image support in Xcode 6)
Does anybody have any idea how to achieve this?

WKWebView - This view allows developers to embed web content in your app. You can think of WKWebView as a stripped-down version of Safari. It is responsible to load a URL request and display the web content. WKWebView has the benefit of the Nitro JavaScript engine and offers more features.
You can implement WKWebView in Objective-C, here is simple example to initiate a WKWebView : WKWebViewConfiguration *theConfiguration = [[WKWebViewConfiguration alloc] init]; WKWebView *webView = [[WKWebView alloc] initWithFrame:self. view. frame configuration:theConfiguration]; webView.
First add the web view as a UIWebView outlet in the storyboard / IB. This will give you a property like this: @property (weak, nonatomic) IBOutlet UIWebView *webView; Then just edit your code to change it to a WKWebView.
Since the asset catalog is stored in the bundle as a single file, there's no way to get an URL to a singular asset.
The simplest solution is to NOT use the asset catalog for images you'll show in a web view.
If keeping the images in the asset catalog is essential, your only option is to "unpack" the required asset(s) into distinct files to the documents directory of the application bundle, and then reference those files.
