Question

I have implemented the following code to assign NSMutableArray to a property –

NSMutableArray * anArray = [responseDictionary valueForKeyPath:@"tags"];
    NSLog(@"The array length is=%d",[anArray count]);
    for (NSString *s in anArray) {

        NSLog(@"you are %@", s);

    }
    [self setActiveTagArray:anArray];

It prints out the string values fine. But in the setter function, if I place a breakpoint I see that it shows there are two objects but they are “Out of Scope”. What does this mean? What am I doing wrong? My getter also does not fetch any values. The property functions –

-(void)setActiveTagArray:(NSMutableArray *)tags
{
   activeTagArray = [[NSMutableArray alloc] init];
   activeTagArray = tags;
   //NSLog(@"%@",[activeTagArray count]);
}

-(NSMutableArray *)getActiveTagArray
{
   return activeTagArray;
}

Answer 1

Is activeTagArray a class variable as well as a property. Consider using _activeTagArray as the class variable name. And then in the .m file just use @synthesize activeTagArray = _activeTagArray;, and for get the second two methods completely.

Response to comment:

You said “I have implemented the following code to assign NSMutableArray to a property”. I took this to mean you have “@property (nonatomic, retain) NSMutableArray *activeTagArray;” in your .h file. If this is the case then you would access it thru otherObject'sNameForYourClassHere.activeTagArray.

@synthesize create accessors & mutators for you.
