UINavigationBar BarButtonItem with Plain Style

i got the following code:

- (id)init {
  if (self = [super init]) {
      self.title = @"please wait";
      UIBarButtonItem *favorite = [[UIBarButtonItem alloc] initWithImage:[UIImage imageNamed:@"star.png"] style:UIBarButtonItemStylePlain target:self action:@selector(buttonFavoriteClicked:)];
      self.navigationItem.rightBarButtonItem = favorite;
  }

  return self;
}

but my button looks still like a Button with UIBarButtonItemStyleBordered alt text

is there a way to set a button with plain style at this position?

Why not try UI7Kit? Works well for me, easy to use.

Although Frank is right, this code should be in viewDidLoad, the issue here is what BarButtons look like. If you want it to look different, you need to use a different type of UIView. You can add a UIButton to a UIToolbar just fine.

-(void)viewDidLoad {
  [super viewDidLoad];
  self.title = @"please wait";
  self.navigationItem.rightBarButtonItem = [[[UIButton alloc] init] autorelease];
}

Edit:

Sorry, you wanted a plain UIBarButtonItem. I don't believe you can do this with a UINavigationBar. You could try adding a UserInteractionEnabled UILabel as the rightBarButtonItem, I'm not sure if it will work or not.

Seems this isn't currently possible.

It's weird but it works. Say "No" to images/outlets! You shouldn't even set the UIBarButtonItemStylePlain property. The trick is to place button into UIToolBar with some special attributes:

UINavigationItem *item = [[UINavigationItem alloc] initWithTitle:@"Cool plain bar"];
UIToolbar *tools = [[UIToolbar alloc]
                    initWithFrame:CGRectMake(0.0f, 0.0f, 44.0f, 44.01f)];
tools.clipsToBounds = NO;
tools.barStyle = -1; // clear background
NSMutableArray *buttons = [[NSMutableArray alloc] initWithCapacity:1];
UIBarButtonItem *bi = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemRefresh target:self action:@selector(refreshTableView)];
[buttons addObject:bi];
[tools setItems:buttons animated:NO];
UIBarButtonItem *rightButtons = [[UIBarButtonItem alloc] initWithCustomView:tools];

item.rightBarButtonItem = rightButtons;
item.hidesBackButton = YES;
[myCoolNavigationBar pushNavigationItem:item animated:NO];

Try this, 

UIBarButtonItem *barBtn = [[UIBarButtonItem alloc]initWithImage:[UIImage imageNamed:@"more.png"] style:UIBarButtonItemStylePlain target:self action:@selector(didPressButton)];

Or do this in code without IB:

// add setting button to nav bar
UIImage* settingsGearImg = [UIImage imageNamed:@"settings_gear.png"];
CGRect frameimg = CGRectMake(0, 0, settingsGearImg.size.width, settingsGearImg.size.height);
UIButton *settingsButton = [[UIButton alloc] initWithFrame:frameimg];
[settingsButton setBackgroundImage:settingsGearImg forState:UIControlStateNormal];
[settingsButton addTarget:self action:@selector(settingsButtonAction) forControlEvents:UIControlEventTouchUpInside];
[settingsButton setShowsTouchWhenHighlighted:YES];
UIBarButtonItem *settingButtonItem =[[UIBarButtonItem alloc] initWithCustomView:settingsButton];
self.navigationItem.leftBarButtonItem = settingButtonItem;

Results in:

    UIImage *img = [UIImage imageNamed:@"white_star.png"];

      CGSize itemSize = CGSizeMake(20, 20);
      UIGraphicsBeginImageContext(itemSize);
      CGRect imageRect = CGRectMake(0.0, 0.0, itemSize.width, itemSize.height);
      [img drawInRect:imageRect];
      img = UIGraphicsGetImageFromCurrentImageContext();
      UIGraphicsEndImageContext();


  UIBarButtonItem *barButton = [[UIBarButtonItem alloc ] initWithImage:img style:UIBarButtonSystemItemAdd target:self action:@selector(favoriteButtonClicked)];
  barButton.style = UIBarButtonItemStyleBordered;

Create a UIButton in interface builder, make it look like exactly what you want. Create an outlet for in in your .h:

IBOutlet UIButton * _myButton;

Then set it as your right bar button item using a custom view, which will eliminate the border:

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

This works because UIButton is a subclass of UIView.

Try this instead:

- (id)init {
  if (self = [super init]) {
      self.title = @"please wait";

      UIButton *button = [[UIButton alloc] initWithFrame:CGRectMake(0, 0, 25, 25)];
      [button setImage:[UIImage imageNamed:@"star.png"] forState:UIControlStateNormal];
      [button addTarget:self action:@selector(buttonFavoriteClicked) forControlEvents:UIControlEventTouchUpInside];
      UIBarButtonItem *favorite = [[UIBarButtonItem alloc] initWithCustomView:button];
      [button release];

      self.navigationItem.rightBarButtonItem = favorite;
  }

  return self;
}

Hope it helps.
