Wikitude

isOlderThaniOSVersion:]: unrecognized selector

Hello,

 

I am trying to "import" a WikitudeStudioiOSAppTemplate in my application framework and get the following error:

 

ARchitect: ARchitect Build: dcc01bf

...

: unrecognized selector sent to instance 0x1567ba20

the original WikitudeStudioiOSAppTemplate runs nicely in the same development environment. 

Is there someting I should have set?

Hi,
Looks like the -ObjC linker flag is missing. Thats why some class categories are not loaded correctly.
You can change the linker flag settings in your Xcode project, simply search for 'OTHER_LDFLAGS' and add '-ObjC'. You can also have a look at the original template project.

Hello,

I have got same error while running application in iPad Mini.

Wikitude SDK: ARchitect Build: b2af9d1

2014-05-31 16:28:51.417 SocialParseAR -: unrecognized selector sent to instance 0x16d648a0

2014-05-31 16:28:51.434 SocialParseAR *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-: unrecognized selector sent to instance 0x16d648a0'

 

Please response me, I have did same trick which mention above. But not work with me. 

Please suggest.

As I mentionned, the -ObjC linker flag fixed the NSCFString isOlderThaniOSVersion error, so I can't really add suggestion. I was on iPhone.

Yep, missing ObjC linker flag. Category methods are not loaded.

Best regards
