I have a UITableView with custom table view cell.
That cell has a custom delete button. Button action is within the cell class.
I can't reload the table from cell class after deleted row from db. If I try to get table view from cell.superview or cell.superview.superview, the app crashes. 
This is cell implementation
@implementation pixSavedTableViewCell
- (IBAction)deleteBusiness:(id)sender {
    NSLog(@"DELETING BUSINESS cell");
    self.hidden=YES;
    pixDBManager *dbConnection = [[pixDBManager alloc]init];
    dbConnection.businessName = self.nameLable.text;
    [dbConnection deleteBusiness];
    //[(UITableView *)self.superview.superview reloadData];
}
@end
This will delete data from
-(void)deleteBusiness
{
    NSLog(@"DELETING BUSINESS");
    char *error;
    if(sqlite3_open([dbPathString UTF8String], &businessDB)==SQLITE_OK){
        NSString *deleteStatement = [NSString stringWithFormat:@"DELETE FROM SAVEDBUSINESS      WHERE 'NAME'='%@'",_businessName];
        const char *delete_stmt = [deleteStatement UTF8String];
        NSLog(@"%s",delete_stmt);
        if (sqlite3_exec(businessDB, delete_stmt, NULL, NULL, &error)==SQLITE_OK) {
            NSLog(@"Business Deleted");
        }
        else{
            NSLog(@"Cant Delete Data");
        }
        sqlite3_close(businessDB);
    }
    else{
        NSLog(@"Cant Open Data Base");
    }
}
This is my view controller implementation
@implementation pixSavedViewController
{
    NSMutableArray *businessArray;
}
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
    self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
    if (self) {
        // Custom initialization
    }
    return self;
}
- (void)viewDidLoad
{
    [super viewDidLoad];
    pixDBManager *dbConnection = [[pixDBManager alloc]init];
    businessArray = [[NSMutableArray alloc]init];
    [dbConnection createOrOpenDB];
    businessArray = [dbConnection getSavedBusiness];
    // Do any additional setup after loading the view.
}
- (void)didReceiveMemoryWarning
{
    [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
    return businessArray.count;
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath      *)indexPath
{
    static NSString *customcellidentifier = @"CustomCell3";
    pixSavedTableViewCell *cell = (pixSavedTableViewCell *)[tableView   dequeueReusableCellWithIdentifier:customcellidentifier];
    if (cell == nil) {
        NSArray *nib = [[NSBundle mainBundle] loadNibNamed:@"Savedcell" owner:self options:nil];
        cell = [nib objectAtIndex:0];
    }
    pixBusinessDetails *details = [[pixBusinessDetails alloc]init];
    details = [businessArray objectAtIndex:indexPath.row];
    cell.nameLable.text = details.name;
    cell.addressLable.text = details.address;
    cell.descriptionLable.text = details.description;
    cell.scoreLable.text = details.score;
    cell.votesLable.text = details.votes;
    NSLog(@"Business Detail %@\n %@\n %@\n %@\n %@\n %@\n",details.name, details.address,details.description,details.score,details.votes,details.imageId);
    return cell;
}
- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{     
    return 130;
}
