How do I make my UITableView Scroll? - iphone

Question

In the following code, I push a new UITableView when I click on a button. The TableView has 25 rows. I can see the first 9 row and the 10th row got cut off. I can't scroll down to view the rest of the rows. How do I make the TableView scrollable? Thank you.
- (IBAction)showListPicker:(id)sender {
ListPicker *lp = [[ListPicker alloc] initWithStyle:UITableViewStyleGrouped];
[self setTitle:#"Home"];
[[self navigationController] pushViewController:lp animated:YES];
[lp release];
}
The following is the declaration for ListPicker
#import <Foundation/Foundation.h>
#interface ListPicker : UITableViewController
{}
#end
The following is the implementation for ListPIcker
#import "ListPicker.h"
#import "GameStore.h"
#import "List.h"
#import "HomeViewController.h"
#implementation ListPicker

{
return [super initWithStyle:UITableViewStyleGrouped];
}

return [self init];
}

[super dealloc];
}
-(void)viewDidLoad{
[self setTitle:#"Select List"];
[[self navigationController] setNavigationBarHidden:NO];
}

{

}
NSArray *allList = [[GameStore defaultStore] allLists];
List *mylist = [allList objectAtIndex:[indexPath row]];

Answer 1

Try to add:
yourTable.scrollEnabled = YES;
Also, when you create your table programmatically, make sure it is "long enough", i.e.,
CGRect cgRct = CGRectMake(0, 0, 320, 600);
yourTable = [[UITableView alloc] initWithFrame:cgRct style:UITableViewStyleGrouped];

Answer 2

Instead of YES, write true as it accepts only bool values.
yourTable.scrollEnabled = true;

Answer 3

Two common ways to change the boolean state of scrolling in a UITableView:
1) It can be enabled either in the attributes inspector of the UITableView via Storyboard.
2) Or programmatically inside your viewDidLoad() via ViewController.
import UIKit
class ViewController: UIViewController, UITableViewDataSource, UITableViewDelegate {
#IBOutlet var yourTable: UITableView!
override func viewDidLoad() {
super.viewDidLoad()
// assign delegate and datasource
yourTable.delegate = self
yourTable.dataSource = self
//enable UITableView scrolling in Swift 3 and Swift 4.
yourTable.isScrollEnabled = true
}
}
