NSMutableArray *indexPathss = [[NSMutableArray alloc] init];
for(int i=0; i<3; i++){

    [photos addObject:s];
    NSIndexPath *indexpath = [NSIndexPath indexPathForRow:i inSection:0];

}

Answer 1

UIButton *moreButton = [[UIButton alloc] initWithFrame:frame];

[moreButton setImage:[UIImage imageNamed:@”button_signin.png”] forState:UIControlStateNormal];

[moreButton addTarget:self action:@selector(showMoreRows) forControlEvents:UIControlEventTouchUpInside];

// Add button to table footer view

self.tableView.tableFooterView = moreButton;

And in method

-(IBAction) showMoreRows {

// Add object in array which is responsible for creating table view and then called

[self.tableView reloadData];

}
