I'm not sure that the Objective-C++ namespace/module proposal wouldn't address the most common issues without the hassle but I fear to get true independence where you can avoid conflicts he is definitely right about having to modify the selector dispatch mechanism and class loader. If dots were valid identifiers then you could go the C# route and just resolve all the references at compile time and turn all selector and class name strings into their fully-qualified equivalents.

For me its solved by closing the project, opening a particular project I know seems to trigger it coming good. compiling it, re-opening the fritzed one and then it works again.

Is there a way to have apple remove bad reviews? Apparently, Anderson Cooper mentioned an app with a similar name to one of mine on his show today, and people are buying mine, then giving it a one star review because it doesn't do whatever the heck the app he showed / talked about on his show did. Anyone have any experience with that sort of thing?

You're mostly hosed - bad reviews don't go away. Can you edit the description and surround it by stars and say "WE ARE NOT {FGSFDS}" or something? Releasing a new version can sweep the ratings under the rug slightly as well as give you the opportunity to clarify in the description that you aren't the app that they're getting confused about.

hosed. Edit your description and update notes to point out that you are a different app and ask people to stop giving you 1-star reviews. Or pull your app from the store for a few days. Edit: also write the Anderson Cooper show. It is just slightly possible that a producer might feel sorry for you and they might make a correction. Unlikely but might as well ask.

Or pull your app from the store for a few days. Hooray. Since my app is old, my screenshots are 320x480, which is no longer acceptable, so I can't edit my description quick....  The good news is, if only a small percentage of people ask for refunds, I made a lot of money today.

Have a quick question about something that I can not get past. I've looked all over for similar questions but none of them have helped. I posted on stack overflow but haven't gotten an answer yet. I'm sending the stringByEvaluatingJavaScriptFromString to my webview while it contains a pdf document, but I'm receiving no returned result when I ask it for the "scrollY" or "document.title". It just returns 0 or nil. I've tried doing a simple javascript function like "2+3" and that gives me the correct answer. I have the UIWebView set up as an outlet to my viewController and it loads my PDF properly. code:code:http://stackoverflow.com/questions/9829947/stringbyevaluatingjavascriptfromstring-on-uiwebview-not-working

If a PDF is loaded, there's no DOM, so I don't know why you'd expect to get an answer from document.title. Where's the title tag? As for window.scrollY, I'm not at all surprised that it doesn't work, but maybe it should. Best I can say is file a radar.

I suppose you want to save the scrollY so you can restore it later when reopening the app/pdf? If you're only ever displaying PDFs, maybe an NSImageView or an IKImageView (they can both show PDFs as far as I know (the latter can for sure)) will suit your needs better, you can wrap that in an NSScrollbar and get at the position pretty easily.

I'm using the position to build a table of contents, as well as other popover information that requires the page number of the PDF. I'll try your recommendation of the (NS/IK)ImageView with the NSScrollbar and report back. Thanks for the quick responses!

Stupid question, but why does the debugger sometimes just go to the main() function for a simple array out of bounds exception? Isn't it supposed to land on the line of code with the error?

It stopped doing that at some point after Xcode 4.0. You can add an exception breakpoint for all exceptions to get it to stop before the stack unwinds.

To elaborate, the exception isn't caught between where it's thrown and the end of main(), so that's why it shows there if you don't have a symbolic breakpoint on Obj-C exceptions.

Pro tip: set the objc exception breakpoint action to po $eax and you'll usually get the handy-dandy exception message right there in the debugger window when it breaks. I'd give my left arm for Visual Studio's debugger in Xcode.

I'm pretty sure the first Cocoa book I read even told me to set that breakpoint (back in the Tiger or Jagwyre days). I've done it ever since.

I'm trying to do some green screen work on a video. I know Apple did some stuff at WWDCC with a sample app Chromakey, but they haven't posted the source. Is there any info out there on how they do it?

Is there any info out there on how they do it? Understand that doing quality greenscreen work can be very involved and complicated. There's a reason the quality keyer plugins for VFX software are usually expensive. With that said, if all all you need is a really basic chroma key, the basic algorithm is probably on Wikipedia. Also look up the color difference method. Is it possible to do something like this using Quartz composer? I've never used it, but maybe give that a look too.

I'm having an utter headfuck of a problem right now. I have an app that uses this library: https://github.com/mochidev/MDSpreadView to do a spreadsheet view (Based on a table pulled off an external DB. I've built it into a library (With -ObjC and -all_load) because it dont do ARC and the rest of the app does. In the simulator it works fine. In debug mode on the ipad it works fine But in an ad-hoc build, it promptly shits itself telling me it doesnt know what setDataSource is, even though its right there in the loving code.  Any idea what could possibly cause this? Its a bit embarassing having this sent back with a "FAIL DUDE" from the client because I was stupid and assumed if it worked in debug it'll work in ad-hoc

When you compile for ad-hoc/release/archive over debug its going to use much more aggressive compilation optimizations. You probably have some reference somewhere that is getting released too early. Try going over stuff you are sending into your blocks maybe you are missing some __block calls. Or something similar. Or something totally different.

Does anybody know anybody reliable who can port an iPhonei/iPad app to Android? It's a children's game I'm working on and the client wants an estimate to port to Android devices. The handful of Android devs I know haven't replied to repeated emails & phone calls requesting a quote. It's a common problem, I understand, not exclusive to the Android community.

But most of the design decisions and architectural requirements have already been worked out. Even though you have to rewrite pretty much everything, it's still significantly faster.

Has anyone tried iOS development on Windows? I searched Google and found mostly outdated links on various options, none of which were particularly satisfactory. The tricky part is I'll be writing an app that integrates with the built-in camera so I need to be able to do that in an emulator to test. Linux is also acceptable since I can just dual-boot into it.

You'll need to find a gcc/llvm toolchain that will poo poo out apropriate binaries, along with the various libraries, then you need a jailbroken phone to run it since you cant sign it on a pc. You pretty much *cant* do it anything for the app store or non jail broken phones though. Also I'm not sure if IOS 5.1 has been jailbroken yet.

It would be an app distributed in the App Store so it would need to be signed. Guess it's not really doable without buying a Mac? Hm. Disappointing.

You also won't find any emulator that simulates camera usage, only a real device will do that. Same with accelerometer and vibrate and anything else a phone does and the computer can't do.
