I'm trying to implement an IOS component inside the Components folder, and noticed the different types of file names:

  • Text.js
  • Image.ios.js
  • SpinnerIOS.ios.js
  • StatusBarIOS.js

What's the idea behind these different names?

.ios.js is a file that's only visible in iOS, we also have .android.js.

This is a way to provide the same module and have a different implementation. Base components such as Image and Text will have the exact same behavior, but call different native implementations, platform specific components such as SpinnerIOS and StatusBarIOS will be a ugly red version, that cannot be used in production but make the app at least run so you can start doing the conversion.

JSONKit usage here may cause serious crash hard to debug(I found the …
bcfb4b4 
…crash on simulator, on device I got nothing but app freezed)!

My app has an old version of JSONKit which is still using MRC. I think JSONKit is not needed if system version is available. Kicking out of JSONKit will make react native stronger.
