ios - Can I change (unsigned) to (NSUInteger) or will it create problems? -


i jr software developer, can change (unsigned) (nsuinteger) or create problems later?

- (unsigned)retaincount {     return uint_max;  //denotes object cannot released }

warning said

mkstoremanager.m:88:1: conflicting return type in implementation of 'retaincount': 'nsuinteger' (aka 'unsigned long') vs 'unsigned int'

i found previous definition

- (nsuinteger)retaincount objc_arc_unavailable;

your method must return nsuinteger because how retaincount method defined in nsobject.

the error being caused value trying return. instead of returning uint_max, should return nsuintegermax.

the underlying type nsuinteger changes depending on whether building 32 or 64 bit. accordingly, value of nsuintegermax changes match type.

- (nsuinteger)retaincount {     return nsuintegermax;  //denotes object cannot released }
