Im working on SpaceViking project from Ray Wenderlich's Cocos2D Book and the project has worked fine so far. Near the end we are told to add Chipmunk files to the Xcode project and compile & run to test everything is fine without adding any new code yet.
As soon as I do that I get many Parse Issue errors coming from NSZone, NSObject and NSObjCRuntime which I don't get otherwise.
Can anyone help me out on this one? It should be an error on some of the added files. How do I find which one and where the error is being generated so I can fix it?
I would check and make sure the added files are 'typed' correctly by Xcode. Make sure they are set to Objective-C, C++ or C (whatever is appropriate in this case). I used to get tons of errors when importing C files that were mistakenly recognized as Objective-C by Xcode. Just changing the file type would solve most of the compile errors. Just and idea.

I absolutely can not understand how it works. I started with a simple one: created framework using "Cocoa Touch Framework" template and add some code to source files. Then using cocoapods I installed some pods to this framework-project. All looks good (maybe not so good actually) and build fine. After that there was an attempt to connect my framework to other xcode project. I did this as follows: just took my test.framework file from Product folder and transferred to another project. At first everything was not bad. The import was successful and I can use my framework-code in another project. But when I run it I have error: dyld: Library not loaded: Reason: image not found. I tried all of the answers to this problem, but nothing helped me.
After that, it was decided to try to connect my framework to other project. This time I got a completely different behavior: namely, I was able to connect the framework, but I could not access the code inside it. I'm completely confused, because I did not change anything. I just did the same with another project.
Please help me. What am I doing wrong?
A related questions:
Can I connect the framework just moving test.framework file into
another project?
For some reason, I should use the approach described above, is there a chance in the theory of success or all that I have done before is not correct?
I tried it a lot with the same result you get , until I posted the problem in Apple forums and they respond with Nested frameworks are not supported in IOS
So, I found myself craving a framework to replicate iOS 6 folders animation. Luckily I found one called JWFolders, which is pretty neat and useful, but my problem is the following:
I am doing my program in Swift, in Xcode 6.3, I imported the header file to the bridging thingy in the swift compiler settings, and as long as I don't try to use anything from that framework, it doesn't complain, but as soon as I try to use it and compile I get the errors shown in the image below.
(even with a simple declaration like this)
var folder = JWFolders()
So, If anyone was wondering, I got it working. I contacted the developer and asked for help, and he nicely told me I was forgetting to add the source code files ".m" to the source compiling files.
After that it worked.
I followed the instructions that came with the framework at the github repository. But I got an error when I tried to compile all stemming from the NSValue+JNWAdditions files. The example project that comes with the code is meant to run in Mac OS X and not iOS. What am I missing here when trying to use this framework for an iOS app? For giggles I removed the aforementioned files and was able to compile but got a runtime error, I guess not surprising. I'm fairly new to this stuff and just want to play with animation and springs :(

Help!
Ah. Got it. For any fellow newbs out there: I had to import UIKit into the header file of NSValue+JNWAdditions.h. This got rid of all the "Expected a type" errors! Makes sense to me now and I have no idea why this took me so long to figure out.
Womp womp
I am fairly new to iOS programming and I'm trying to make an iOS 5.1 app that communicates with a server to receive information from a database. I got the server returning the needed information from the database by following this tutorial:
http://www.raywenderlich.com/2941/how-to-write-a-simple-phpmysql-web-service-for-an-ios-app
But then I tried to follow a the other half of the tutorial by the same guy:
http://www.raywenderlich.com/2965/how-to-write-an-ios-app-that-uses-a-web-service
In this one we use JSON, ASIHTTPRequest and MBProgressHUD, but I get a lot of errors when I run this because ASIHTTPRequest is no longer supported in iOS 5.1.
Can anyone point me in the right direction here? I you can show me another tutorial that works for iOS 5.1 that would be great. I have looked but I can't find any.
Thanks
ASIHTTPRequest is most likely returning errors in your iOS 5.1 app because you're using ARC. ASIHTTPRequest wasn't written in ARC, which is why it's throwing tons of errors. But there's an easy workaround:
In Xcode 4's groups and files pane, select your project file at the top of the list.
Select your target towards the left hand panel.
You should now see a list of all the implementation (.m) files referenced and compiled throughout the course of the program.
Double click the implementation files for ASIHTTPRequest and add the following linker flag: -fno-objc-arc. This linker flag acts as a crossbridge between the old non-ARC files and your ARC-based project.
Although there may be residual warnings left, this trick should remove all other error messages associated with ASIHTTPRequest.
When I followed that same tutorial I got a lot of errors. and the build kept failing until I reliased it was because libz.1.2.3.dylib wasnt there. If you go to Build Phases, remove that from the list and add libz.1.2.5.dylib all mine worked first and I got the app working fully :)
I am facing what seems to be a pretty wide spread issue : when I activate code coverage in Xcode (4.2.1) with Lion it shows the following error :
Detected an attempt to call a symbol in system libraries that is not present on the iPhone:
fopen$UNIX2003 called from function llvm_gcda_start_file
I followed the workaround described here and added a file to my test target with a mapping for the fopen function but it won't work for me. With the new C file, I get a lot of Parse and Semantic issues, as if it was completly messing the compilator up.
Is there a specific config/compiler option I am missing ? How exactly should I add the new file ?
Actually the problem was fixed when I renamed the .c file in a .m file... I don't know if it could be an issue linked to ARC for instance.
