bigLabel.font =[UIFont boldSystemFontOfSize:21.0f];

[self.navigationItem setTitleView:bigLabel];

Answer 1

Use the following code :

UITapGestureRecognizer* tapRecon = [[UITapGestureRecognizer alloc]
              initWithTarget:self action:@selector(navigationBarTap:)];
    tapRecon.numberOfTapsRequired = 1;
    [navController.navigationBar addGestureRecognizer:tapRecon];

Answer 2

you need to set

bigLabel.userInteractionEnabled = YES;

because by default UILabel instances userInteractionEnabled is NO

Answer 3

Try setting a frame to it like so:

UIView *iv = [[UIView alloc] initWithFrame:CGRectMake(0,0,32,32)];
[iv setBackgroundColor:[UIColor whiteColor]];
self.navigationItem.titleView = iv;

Answer 4

 UITapGestureRecognizer * tapGesture = [[UITapGestureRecognizer alloc]
                                            initWithTarget:self
                                            action:@selector(hideKeyBoard)];

    tapGesture.cancelsTouchesInView = NO;
    [self.navigationController.view addGestureRecognizer:tapGesture];


-(void)hideKeyBoard
{
    [self.view endEditing:YES];
}
