Using native images in Cordova

Question

I want to use custom images for tab bar icons, as set in this line using this extension: https://github.com/squerb/cordova-ios-tab-bar (imageName is passed through the extension from the javascript):

item = [[UITabBarItem alloc] initWithTitle:title image:[UIImage imageNamed: imageName] tag:tag];

I'm struggling to work out where I need to put the image in my Cordova project so that it's accessible by the native code. If indeed that's possible.

I've tried this:

item = [[UITabBarItem alloc] initWithTitle:title image:[UIImage imageNamed:@"www/assets/failed.png"] tag:tag];

But that results in this error:

第二种形式，引用了xcode项目目录中可见的路径，在cordova的情况下，“ www / images / whatever.png”应该可以正常工作，只是出于某种原因在开始工作之前只需要给它一些提示即可。
