__NSCFNumber return negative value

Question

For some reason i cant set my NSNumber value.

Code is simple:

    obj.objectId = [filteredArr[i] valueForKey:@"idx"];

Where [[filteredArr[i] valueForKey:@"idx"] class] is __NSCFNumber.

It should be a number from 0 to 200.. but it is actually -5764607523034234861

`[[filteredArr[i] valueForKey:@"idx"] integerValue]`? `objectId` is supposed to be a NSNumber, NSInteger, etc. ? — Larme, May 27 '16 at 12:32
NSLog(@"mutArNam %ld", (long)[((CIdNamedObject*)mutArr[0]).objectId integerValue]); still shows -5764607523034234861 — Evgeniy Kleban, May 27 '16 at 12:33
If you log `NSLog(@"Value: %@", [filteredArr[i] valueForKey:@"idx"])`, you have the wrong one? — Larme, May 27 '16 at 12:35
issue is in creating your dict ** 5764607523034234861** Garbage value happens when type mis-match like putting long range value at place of int range — Prashant Tukadiya, May 27 '16 at 12:47

NSNumber and NSString respond to the methods -intValue which returns an int.

NSNumber *myNumber = @([[filteredArr[i] valueForKey:@"idx"]intValue]);

This may help you.
