UINavigationBar BarButtonItem with Plain Style - iphone

Question

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

Answer 1

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.

Answer 2

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.

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:
When using this icon image (it's white on a white background so isn't visible here - link is: http://i.stack.imgur.com/lk5SB.png):

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];

Answer 5

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.
sbwoodside has a solution.

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

Answer 7

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;

Answer 8

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