Cannot add object to an NSMutableArray array

Question

@interface SimataDetailViewController () 

@property Simata *simata;

@property (nonatomic, copy) NSMutableArray *simataList;

@end

@implementation SimataDetailView         


        

Answer 1

Are you sure you have created an instance of the array before you use it?

self.simataList =[NSMutableArray array];

It could also be your self.simata being nil...

EDIT

You could create the array instance in the default init method:

-(id)init
{
    self = [super init];
    if(self)
    {
        //do your object initialization here
        self.simataList =[NSMutableArray array];
    }
    return self;
}

Answer 2

Most likely self.simataList is nil. Try NSLogging self.simataList itself, rather than its count.
