xcode - UIDeviceRGBColor isEqualToString:]: unrecognized selector -

-

can tell me about? have table , inside tablecell have pickerview , textfields in other cells. when i'm scrolling table , down 8-10 times app crashes , gives me error:

* terminating app due uncaught exception 'nsinvalidargumentexception', reason: '-[uidevicergbcolor isequaltostring:]: unrecognized selector sent instance 0x5834850'

short answer: trying call -isequaltostring: on instance of uidevicergbcolor, doesn't respond it.

long answer: you're either asking wrong object @ point, or quite possibly trying access object has been released, who's pointer has not been set nil. when happens you'll straight crash memory in new location isn't proper object. new object takes place. best way find out turn on zombies.

this overview of how use zombies: http://iosdevelopertips.com/debugging/tracking-down-exc_bad_access-errors-with-nszombieenabled.html

you may start seeing messages saying "-[nscfstring isequaltostring:] message sent deallocated instance". if memory management problem , need double check retains & releases. if don't message calling wrong method , getting wrong object back.
