From bca85101cd25385a8e534c1ba7fff6b30e426b51 Mon Sep 17 00:00:00 2001 From: Albert Martin Date: Wed, 20 Feb 2019 22:54:42 -0800 Subject: [PATCH] fix: prevent exception when imageName is null (#20120) Summary: When an image source is parsed via `RCTImageFromLocalAssetURL` there seem to be certain situations in which `imageName` is empty from `RCTBundlePathForURL`. Any call to `UIImage imageNamed` with a an empty parameter will throw an exception: ``` CUICatalog: Invalid asset name supplied: '(null)' ``` In my case, the asset URL was pointing to an image in the application sandbox rather than the `NSBundle`. In this case `UIImage imageNamed` was throwing before the call to `NSData dataWithContentsOfURL` below could correctly resolve the image. This change simply skips the call to `UIImage imageNamed` if no `imageName` value is set.
