How to add a right button to a UINavigationController?

Question

I am trying to add a refresh button to the top bar of a navigation controller with no success.

Here is the header:

@interface PropertyViewController

UIView *view = [[UIView alloc]initWithFrame:CGRectMake(0, 0, 110, 50)];
view.backgroundColor = [UIColor clearColor];

UIButton *settingsButton =  [UIButton buttonWithType:UIButtonTypeCustom];
[settingsButton setImage:[UIImage imageNamed:@"settings_icon_png.png"] forState:UIControlStateNormal];
[settingsButton addTarget:self action:@selector(logOutClicked) forControlEvents:UIControlEventTouchUpInside];
[settingsButton setFrame:CGRectMake(40,5,32,32)];
[view addSubview:settingsButton];

UIButton *filterButton =  [UIButton buttonWithType:UIButtonTypeCustom];
[filterButton setImage:[UIImage imageNamed:@"filter.png"] forState:UIControlStateNormal];
[filterButton addTarget:self action:@selector(openActionSheet) forControlEvents:UIControlEventTouchUpInside];
[filterButton setFrame:CGRectMake(80,5,32,32)];
[view addSubview:filterButton];



self.navigationItem.rightBarButtonItem = [[UIBarButtonItem alloc] initWithCustomView:view];
