What's the 'good' use for extracting the resources for somebody else's app? I'm sure there is one.. I'm just missing it.
@chrismaddern I like using full res icons in my mock ups. Crunch makes it easier to pull out an app icon in various sizes and with different mask shapes.
Super useful during a design/mocking session. You can poke around an .ipa file for graphic assets — but why? This app'll take care of it for you.
I have to agree with @chrismaddern here. This seems (mostly) like a tool to grab someone else's work and use it without having to create it yourself. And while imitation may be the sincerest form of flattery, copying (or stealing) isn't. Over the weekend someone on my twitter feed found a facebook programmer that had copied the Jelly website entirely and edited for his own website. But he left a lot of the Jelly assets and pages (including the blog!) on his site. Sometimes I do want to look under the hood of someone else's project in a "how'd they do that" sort of way, but straight out taking someone else's assets for your own project doesn't seem right.
@chrismaddern @GoLocalApps You can learn from other apps by looking how they are built and Crunch makes it easy to extract the assets. If someone wants to steal the assets, he could do it even if Crunch didn't exist, it's really not a big deal to extract an ipa file. You can extend this to other tools like: looking at a web page source using Safari, using a hex editor, class-dumping an executable… I make apps for a living and spend a lot of time to design them. I certainly don't like piracy and resource stealing. Crunch warns you that you shouldn't share or copy images from someone else: And Crunch is much more: it makes icons, it's a Quick Look plugin, it has an icon composer. Note: I'm the developer of Crunch.
@chrismaddern @GoLocalApps @benoitsan exactly. As I said above, I like to use hi-res image assets in mockups, tweets, or elsewhere. If more app makers made it easier to grab their logo or app icon from their site, I'd just use that — but most don't. In fact, I used Crunch to extract a Product Hunt icon from their mobile app for an Alfred Workflow I made because @rrhoover hasn't shared any branding assets on this site (at least that I could find).
@chrismessina FYI, we have a .zip of assets available via our FAQ, downloadable here.
@chrismaddern @benoitsan To be clear, I wasn't accusing anyone of using it to steal assets, just seemed that Crunch was just making it easier for people to do it. And we all know there are plenty of people making a living stealing and cloning apps and I don't like making their lives any easier.
like ResEdit for iOS? :) #retro
