NSMutableArray insertion in objective-C

Question

I am using the following code to add NSNumber to a NSMutableArray

in header file:

NSNumber *timeInSeconds;
NSMutableArray *time;

in code:

int total=6;
timeInSeconds=[NSNumber numberWithInt:total];
[time addObject:timeInSeconds];

However, while debugging, I noticed that if I do

print (int) [time count]

I get an output of 0... Not sure why this is happening...can anyone kindly help me?

Thanks.

I don't see where you allocated time . At some point you need to call

time = [[NSMutableArray alloc] init];

or some other allocation and initialization method.
