Am I using my data source array correctly?

When I want to make some quick tests for my UITableViewControllers, I usually create an NSArray that holds some dummy data. I would like to know if I'm doing anything wrong here:

First in MasterViewController.h:

#import <UIKit/UIKit.h>

@class DetailViewController;

@interface MasterViewController : UITableViewController

@property (nonatomic, retain) NSArray *dataSourceArray;

@end

and then in MasterViewController.m:

#import "MasterViewController.h"

@implementation MasterViewController

@synthesize dataSourceArray = _dataSourceArray;

- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
    self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
    if (self) {
        self.title = NSLocalizedString(@"Master", @"Master");
        _dataSourceArray = [[NSArray alloc] initWithObjects:@"obj 1", @"obj 2", @"obj 3", nil];
    }
    return self;
}

- (void)dealloc
{
    [_dataSourceArray release];
    [super dealloc];
}

So, the real question, as long as I'm not assigning _dataSourceArray to something else, I'm safe in terms of memory management here, right?
