How can I transit to another viewController in a customised tableViewController?

I am customising the table view cell by a subclass of uitableviewcell. So, how can I transit from this view controller to another when the cell is touched? Thanks.

It seems that doing the implementation in tableview: didSelectRowAtIndexPath: doesn't work. Here is my code:

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath{
    SecondViewController *anotherViewController = [[SecondViewController alloc] init];
    [[self navigationController] pushViewController:anotherViewController animated:YES];
}

This is what I got when I press the row in the table view: enter image description here

And this is the code in myCell.m (my customised cell):

- (id)initWithStyle:(UITableViewCellStyle)style reuseIdentifier:(NSString *)reuseIdentifier
{
self = [super initWithStyle:style reuseIdentifier:reuseIdentifier];
if (self) {

    self.mainLabel = [[UILabel alloc] initWithFrame:CGRectMake(5, 5, 180, 30)];
    self.mainLabel.font = [UIFont systemFontOfSize:14.0];
    [self.contentView addSubview:self.mainLabel];

    self.mainButton = [UIButton buttonWithType:UIButtonTypeSystem];
    self.mainButton.frame = CGRectMake(190, 5, 100, 30);
    [self.mainButton addTarget:self action:@selector(logButton:) forControlEvents:UIControlEventTouchUpInside];
    [self.contentView addSubview:self.mainButton];

}
return self;
}

- (void)logButton:(UIButton *)sender{
   NSLog(@"index path: %ld", (long)sender.tag);
}

- (void)setSelected:(BOOL)selected animated:(BOOL)animated
{
   [super setSelected:selected animated:animated];

 }

My guess: Your didSelect method gets called but your SecondViewController is nil. Give your new controller an identifier in your storyboard and do 

SecondViewController *controller = [self.storyboard instantiateViewControllerWithIdentifier:@"Second"];

Otherwise your controller is just empty, because it's not connected to the storyboard. In fact, only the storyboard knows that your custom class exists, not the other way round.

If you don't use storyboard, init your SecondViewController with initWithNibName:bundle: instead... and put that new init method in your old one.. so init calls initWithNibName:bundle: internally. This way no one has to know the name of your xib file and the code is much shorter.

if use want to transit on the touch event of any uicontrols then you need to add selector methods and add code for transition there or you can transit from uitableView delegate method didSelectRowAtIndexPath:

This is the delegate method of tableView and will called automatically when you tap a cell. 

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath{
}
