Loaded the nib but didn't get a UITableView

I have been following this tutorial on YouTube (part 1 and part 2).

I have completed both videos and have hooked up the view controller with the parent view controller using this code:

- (IBAction)searchButtonClicked:(id)sender {
    NSLog(@"It works.");

    SearchViewController *searchViewControl = [self.storyboard instantiateViewControllerWithIdentifier:@"SearchControllerNav"];

    [self presentViewController:searchViewControl animated:YES completion:nil];

}

This code indeed works since this is the same format that I use for my other modal view controllers, so i know that's not the problem.

Anyway, when I tap on the search button in the view controller, it should pop up the SearchViewController. However, the app crashes instead and it gives me this error message:

Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: '-[UITableViewController loadView] loaded the "jp7-vt-IdA-view-Jer-xW-qlD" nib but didn't get a UITableView.'

I am using Storyboards for this app.

Is there something that I'm missing? Thank you in advance.

A side question: I'm also getting a warning, saying Comparison between pointer and integer ('BOOL *' (aka 'signed char *') and 'int') whenever isFiltered == YES is shown. Is there anyway to fix it?

Here is the code for SearchViewController:

SearchController.h

#import <UIKit/UIKit.h>

@interface SearchViewController : UITableViewController <UITableViewDelegate, UITableViewDataSource, UISearchBarDelegate> {

}
- (IBAction)cancelButtonTapped:(id)sender;

@property (weak, nonatomic) IBOutlet UISearchBar *mySearchBar;
@property (weak, nonatomic) IBOutlet UITableView *myTableView;

@property (nonatomic, strong) NSMutableArray *itemsInCloudApp;
@property (nonatomic, strong) NSMutableArray *filteredList;
@property BOOL *isFiltered;


@end

SearchViewController.m

#import "SearchViewController.h"

@interface SearchViewController ()

@end

@implementation SearchViewController

@synthesize mySearchBar, myTableView, itemsInCloudApp, filteredList, isFiltered;

- (void)viewDidLoad
{
    [super viewDidLoad];

    // Set title.
    UILabel *titleLabel = [[UILabel alloc] initWithFrame:CGRectZero];
    titleLabel.text = @"Search";
    titleLabel.adjustsFontSizeToFitWidth = YES;
    titleLabel.clipsToBounds = YES;
    titleLabel.numberOfLines = 1;
    titleLabel.font = [UIFont fontWithName:@"Avenir-Medium" size:18];
    titleLabel.textColor = [UIColor blackColor];
    titleLabel.autoresizingMask = UIViewAutoresizingFlexibleHeight;
    titleLabel.textAlignment = NSTextAlignmentCenter;
    [titleLabel sizeToFit];

    self.navigationItem.titleView = titleLabel;

    // Alloc and init list.
    itemsInCloudApp = [[NSMutableArray alloc]initWithObjects:@"http://www.apple.com/", @"http://www.trijstudios.com/", @"http://www.google.com/", @"http://www.squarespace.com/", @"http://www.youtube.com/", nil];
}

#pragma mark - Table view data source

- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
    // Return the number of sections.
    return 1;
}

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
    // Return the number of rows in the section.
    if (isFiltered == YES) {
        return [filteredList count];
    } else {
    return [itemsInCloudApp count];
    }
}

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    static NSString *CellIdentifier = @"Cell";
    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath];

    // Configure the cell...

    if (isFiltered == YES) {
        cell.textLabel.text = [filteredList objectAtIndex:indexPath.row];
        cell.detailTextLabel.text = [filteredList objectAtIndex:indexPath.row];;
    } else {
        cell.textLabel.text = [itemsInCloudApp objectAtIndex:indexPath.row];
        cell.detailTextLabel.text = [itemsInCloudApp objectAtIndex:indexPath.row];
    }

    return cell;
}

-(void)searchBar:(UISearchBar *)searchBar textDidChange:(NSString *)searchText {
    if (searchText.length == 0) {
        // Set bollean flag
        isFiltered = NO;
    } else {
        // Set boolean flag
        isFiltered = YES;

        // Alloc and init our fliteredData
        filteredList = [[NSMutableArray alloc] init];

        // Fast enumeration
        for (NSString *name in itemsInCloudApp) {
            NSRange nameRange = [name rangeOfString:searchText options:NSCaseInsensitiveSearch];

            if (nameRange.location != NSNotFound) {
                [filteredList addObject:name];
            }
        }
    }
    // Reload tableView
    [myTableView reloadData];

}

-(void)searchBarSearchButtonClicked:(UISearchBar *)searchBar {
    [mySearchBar resignFirstResponder];
}

- (IBAction)cancelButtonTapped:(id)sender {

    [self dismissViewControllerAnimated:YES completion:nil];

}
@end

NOTE: There are a few edits that I made to fit my needs.

have you tried changing your @interface SearchViewController : UITableViewController to @interface SearchViewController : UIViewController

I strongly suspect that either you have not attached your UITableview as View in XIB or your class should be derived UIViewController instead of UITableviewController class..
