Error parsing Default.NUI

[subaMmackowski]

am getting a bad access EXC_BAD_ACCESS on line 17 in NUIDefinition.h

this line @Property (strong) NSString *variable;

This only happens when I try to init NUI like this: [NUISettings initWithStylesheet:@"Blue.NUI"];

it work fines this way: [NUIAppearance init];

I didn't use CocoaPods and I can't use CocoaPods due to the nature of my project. I did not have any trouble adding NUIParse to the project.

Thanks for the report. Could you post a stacktrace and the line it is crashing on (please provide a couple lines above and below for context)? I am thinking it may very well be possible you didn't install the proper version of NUIParse.

[subaMmackowski]

I install https://github.com/tombenner/NUIParse

I added it as a subproject as instructed by the NUI read me.

The call starts with:

Any insights or help?

[Stunner]

You mentioned that it crashes within CPShiftReduceParser but there is no such class in NUIParse. Something seems fishy here. Are you sure your project doesn't have CoreParse included in it? It should be using only NUIParse to avoid any such conflicts/erroneous behavior.

[Stunner]

Also, is your project using ARC? If it isn't, this may be a source of contention as the EXC_BAD_ACCESS is caused when an object is overreleased.

[subaMmackowski]

NUIParse project doesn't compile if its set to use ARC.

I updated my original post.

Here is the call stack again.

[subaMmackowski]

Is the manual install method correct? I mean this step.

"Add NUIParse as a subproject, set its iOSNUIParse target as a dependency of your target, and add libNUIParse.a to your linked libraries."

When I do that I get linking errors because there are duplicate symbols.

[subaMmackowski]

I just made NUIParse a subproject and a target dependency.

[subaMmackowski]

Anyways I cannot get it to parse one of the style sheets provide in the project.

[Stunner]

Would it be possible for you to create a sample project with this exact issue that you could provide to me? I would then happily investigate and attempt to fix this issue. It's hard otherwise (unless you are willing to fix it of course).

Not sure about manual setup instructions as I have never done it before. Both active maintainers (including me) use CocoaPods and are not privy to the specifics of manual installation (which was written long ago). I'd have to dig a bit into a project with problems to understand the cause/attempt a fix.

[subaMmackowski]

Ok, I will set up a sample project when I get the chance. Thanks for the
reply..

I am really swamped at work and maybe a while before I can get your a
project.
