I've been trying for days to determine why I get EXC_BAD_ACCESS when I try to access a managedObject property from within an accessor of another property?
this code in main.m
[[self note] setValue:@"HELLO WORLD" forKey:@"category"];
NSNumber *tmpVal = [NSNumber numberWithBool:![[[self note] valueForKey:@"isEncrypted"] boolValue]]; // if I type po [self note] I see the note description
[[self note] setValue:tmpVal forKey:@"isEncrypted"]; // if I type po [self note] after this I get EXEC_BAD_ACCESS
The if statement in the accessor is causing the problem:
- (NSString *)category {
NSString * tmpValue;
[self willAccessValueForKey:@"category"];
tmpValue = [self primitiveCategory];
[self didAccessValueForKey:@"category"];
if ([[self valueForKey:@"isEncrypted"] boolValue]) { // THIS IS CAUSING THE PROBLEM
// code to decrypt tmpValue
}
return tmpValue;
}
When I replace: if ([[self valueForKey:@"isEncrypted"] boolValue]) with if (1 == 2 ) or if (1 == 1 ) it works
FYI: in my .h file @property (nonatomic, retain) NSNumber * isEncrypted; and @dynamic isEncrypted; in .m_______________________________________________
