-(BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldReceiveTouch:(UITouch *)touch {
    //Touch gestures below top bar should not make the page turn.
    //EDITED Check for only Tap here instead.
    if ([gestureRecognizer isKindOfClass:[UITapGestureRecognizer class]]) {
        CGPoint touchPoint = [touch locationInView:self.view];

        NSUserDefaults * userDefaults = [NSUserDefaults standardUserDefaults];
        bool pageFlag = [userDefaults boolForKey:@"pageDirectionRTLFlag"];
        NSLog(@"pageFlag tapbtnRight %d", pageFlag);

        if(self.interfaceOrientation==UIInterfaceOrientationPortrait||self.interfaceOrientation==UIInterfaceOrientationPortraitUpsideDown) {
  NSString *imgURL = [NSString stringWithFormat:@"document.elementFromPoint(%f, %f).src", touchPoint.x, touchPoint.y];
            NSString *urlToSave = [webView stringByEvaluatingJavaScriptFromString:imgURL];
            NSLog(@"urlToSave :%@",urlToSave);

Check this out.

-(BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldReceiveTouch:(UITouch *)touch {
NSLog(@"TAPPED");
//Touch gestures below top bar should not make the page turn.
//EDITED Check for only Tap here instead.
if ([gestureRecognizer isKindOfClass:[UITapGestureRecognizer class]]) {
    CGPoint touchPoint = [touch locationInView:self.view];

    NSUserDefaults * userDefaults = [NSUserDefaults standardUserDefaults];
    bool pageFlag = [userDefaults boolForKey:@"pageDirectionRTLFlag"];
    NSLog(@"pageFlag tapbtnRight %d", pageFlag);

    if(self.interfaceOrientation==UIInterfaceOrientationPortrait||self.interfaceOrientation==UIInterfaceOrientationPortraitUpsideDown) {
        NSString *imgURL = [NSString stringWithFormat:@"document.elementFromPoint(%f, %f).src", touchPoint.x, touchPoint.y];
        NSString *urlToSave = [webV stringByEvaluatingJavaScriptFromString:imgURL];
        NSLog(@"urlToSave :%@",urlToSave);
        NSURL * imageURL = [NSURL URLWithString:urlToSave];
        NSData * imageData = [NSData dataWithContentsOfURL:imageURL];
        UIImage * image = [UIImage imageWithData:imageData];
        imgView.image = image;//imgView is the reference of UIImageView
    }
  }
return YES;
}
