Hide keyboard when scroll UITableView

Question

In my app i want hide keyboard when i start scrolling UITableView. I search about this in internet, and most answer is subclassing UITableView (http://stackoverflow.com/questions/3499810/tapping-a-uiscrollview-to-hide-the-keyboard).

I made subclass but it's dont work.

#import <UIKit/UIKit.h>

@protocol MyUITableViewDelegate <NSObject>
@optional
- (void)myUITableViewTouchesBegan;
@end

@interface MyUITableView : UITableView <UITableViewDelegate, UIScrollViewDelegate> {
    id<MyUITableViewDelegate> delegate;
}
@end

.m file

#import "MyUITableView.h"

@implementation MyUITableView

- (void)scrollViewDidScroll:(UIScrollView *)scrollView{
    NSLog(@"delegate scrollView"); //this is dont'work
    [super scrollViewDidScroll:scrollView];
}

- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {
    NSLog(@"delegate myUITableViewTouchesBegan"); // work only here
    [delegate myUITableViewTouchesBegan];
    [super touchesBegan:touches withEvent:event];

}

- (void)dealloc {
...

I use this class like this. But delegate function myUITableViewTouchesBegan don't work in ViewController

.h

#import <UIKit/UIKit.h>
#import "MyUITableView.h"

@interface FirstViewController : UIViewController <UITableViewDelegate, UISearchBarDelegate, MyUITableViewDelegate> {
    MyUITableView *myTableView;
    UISearchBar *searchBar; 
}

@property(nonatomic,retain) IBOutlet MyUITableView *myTableView;
...

.m

- (void) myUITableViewTouchesBegan{
    NSLog(@"myUITableViewTouchesBegan");
    [searchBar resignFirstResponder];
}

I have some troubles with this implemenation:
1) myUITableViewTouchesBegan dont work in ViewController
2) NSLog from MyUITableView.m - NSLog(@"delegate myUITableViewTouchesBegan"); work only when i touch table. How made it's work also when i start scrolling?
I try override scrollViewDidScroll but comiler said that MyUITableVIew may be don't respond on this string [super scrollViewDidScroll:scrollView];

Here is the cleanest way to achieve this in iOS 7.0 and above:

tableView.keyboardDismissMode = UIScrollViewKeyboardDismissModeOnDrag;

Or to dismiss interactively when touching:

tableView.keyboardDismissMode = UIScrollViewKeyboardDismissModeInteractive;

Or in Swift:

tableView.keyboardDismissMode = .onDrag

To dismiss interactively:

tableView.keyboardDismissMode = .interactive
