Unrecognized selector sent to instance
Can anyone tell me what is going on in this error code? Man apple is cryptic. I have just made a call via ObjectiveResource to data I know is fine.
-[NSDecimalNumber allKeys]: unrecognized selector sent to instance 0x5c671f0

As others pointed NSDecimalNumber
does not respond to allKeys
selector and that causes a crash.
That may happen because the instance of NSDictionary, the intended message responder was prematurely deallocated for some reason (lack of retain?) and its address in memory got occupied by NSDecimalNumber
instance that gets that wrong message.
So to fix that problem try locating the line that message and check if everything is ok with memory management in that code.
You calling allKeys method on NSDecimalNumber
,and NSDecimalNumber
can,t use this method thats why you having a crash.
allKeys method call with NSDictionary
or NSMutableDictionary
.
so type where
after getting this log you get line number at there you need to edit the code.
NSDecimalNumber does not support the method allKeys.
