This is driving me crazy, I can not figure out what that black line is behind my search bar.
My view hierarchy is a UINavigationController -> UITableViewController with a SearchDisplayController, and I customize the appearance of the search bar with the following code:
[[UISearchBar appearance] setImage:[ApplicationStyle searchBarIconImage] forSearchBarIcon:UISearchBarIconSearch state:UIControlStateNormal];
[[UISearchBar appearance] setBackgroundImage:[ApplicationStyle searchBarImage]];
[[UISearchBar appearance] setSearchFieldBackgroundImage:[ApplicationStyle searchBarFieldImage] forState:UIControlStateNormal];
The image I am using for the background is 640px x 88px and it is not transparent by any means. Any ideas what this could be?
Set the search bar's clipsToBounds property to YES.
Relevant SO questions:
Is it possible to change the border color of a UISearchDisplayController's search bar?

I'm trying to handle the rotation of a UINavigationBar with UINavigationItem (i'm not using the UINavigationController), i have successfully made so that the height and width show according, but that does not seems to be correct, as the UINavigationBar still acts as being in portrait mode (big title and button), also when i set a custom background for both metrics, it seems to only show the portrait background metric, ignoring completely the landscape one.
[[UINavigationBar appearance] setBackgroundImage:[UIImage imageNamed:#"modal-top-landscape"] forBarMetrics:UIBarMetricsLandscapePhone];
[[UINavigationBar appearance] setBackgroundImage:[UIImage imageNamed:#"modal-top"] forBarMetrics:UIBarMetricsDefault];
Is there a way to tell the UINavigationBar that is rotated and should show the text and buttons accordingly?
I attach some screenshots:
One workaround for this is to use a UINavigationController, and use a CGRectOffset to remove the margin that leaves the status bar... add the Controller to the parent controller (also the view).
I'm using a custom Navigation Bar appearance in my app with this code in the App Delegate's application:didFinishLaunchingWithOptions: method:
[[UINavigationBar appearance] setBackgroundImage:[UIImage imageNamed:#"navBar.png"] forBarMetrics:UIBarMetricsDefault];
[[UINavigationBar appearance] setBackgroundColor:[UIColor clearColor]];
However, this appearance breaks when I present an ABPeoplePickerNavigationController (to allow selection of a contact to populate the To: field for a new email), because the system uses an extra tall UINavigationBar when this view is showing due to the prompt property on UINavigationItem being set by the system ("Choose a contact to mail").
The fix is to add this code:
[[UINavigationBar appearanceWhenContainedIn:[ABPeoplePickerNavigationController class], nil] setBackgroundImage:nil forBarMetrics:UIBarMetricsDefault];
[[UINavigationBar appearanceWhenContainedIn:[ABPeoplePickerNavigationController class], nil] setBarStyle:UIBarStyleBlack];
Which looks like this:
However, this little hack doesn't work when you tap the Groups button from the initial view. It still looks broken due to the extra tall Navigation Bar:
Any ideas what the controller name is for that view (so I can apply the same exclusion as above), or another way to fix this?
I'm just hitting this now.. any luck resolving? I'm thinking to try interating through the ABPeoplepickerNavigationControllers view controllers and applying appearanceWhenContainedIn method...
I've been fighting with this as well, but think I've pieced together a solution.
The group selection view is some other (unknown to me, likely private) class, so we can't specify an exception style through an appearance-proxy-when-contained-in approach, as you've done for the ABPeoplePickerNavigationController. Instead, we should try and resolve the original issue, which is the custom background image not rendering properly when the prompt is shown and the navigation bar is tall.
The solution here (iOS5 UINavigationBar background image issues when prompt is shown) suggests using a resizable background image for the navigation bar.
That almost worked for me, but the background image I was using included the shadow for underneath the navigation bar and that wasn't resizing correctly when the prompt was shown. Instead, I had to use a resizable background image without a shadow and then specify the shadow image separately.
UINavigationBar* navigationBar = [UINavigationBar appearance];
[navigationBar setBackgroundImage:[[UIImage imageNamed:#"TopBarBackgroundNoShadow"] resizableImageWithCapInsets:UIEdgeInsetsMake(3, 0, 3, 0)]
forBarMetrics:UIBarMetricsDefault];
[navigationBar setShadowImage:[UIImage imageNamed:#"TopBarShadowResize"]];
Using this approach removed the need for any exception styling and looked good in both the ABPeoplePickerNavigationController and the group selection view, as well as at standard height.
I'm trying to set the tintColor of a UIBarButtonItem in method that gets called when my program starts. I set up all my views using storyboards. I then customize the appearance of the views using the new iOS5 guidelines for using appearance proxies. I've customized the background of the navigation bar by doing the following:
- (void)customizeAppearance
{
UIImage *leatherTexture = [[UIImage imageNamed:#"BrownLeather#2x.png"] resizableImageWithCapInsets:UIEdgeInsetsMake(0, 0, 0, 0)];
[[UINavigationBar appearance] setBackgroundImage:leatherTexture
forBarMetrics:UIBarMetricsDefault];
[[UINavigationBar appearance] setBackgroundImage:leatherTexture
forBarMetrics:UIBarMetricsLandscapePhone];
[[UIBarButtonItem appearance] setTintColor:[UIColor clearColor]];
}
I was hoping that by setting the UIBarButtonItem tintColor to clear would allow me to easily use the default button styles while having a custom background texture. However, setting the tintColor to clear just turns the button black as opposed to being transparent or clear. Any ideas what I'm doing wrong? Is there a way to create a clear button without having to use custom images for the buttons? See the image below:
You can't do this way (because IMO the default background of UIBarButtonItem is black. and new tint color is over-layered on it).
However you can customize your UIBarButtonItem with using UIButton (with background) as customView in UIBarButtonItem.
Or if you are targeting iOS 5 only you can use brown tint color (which will be flat and will not show background image)
Just found out that in Xcode 4.5 you can just drag a UIButton into the UIBarButton in the Storyboard. The UIButton is then fully customizable.
How to add colour to the navigation bar ? I need to implement this for iOS 4 and above.
I want a colour similar to the one in the screenshot:
In the example you posted, It looks more like a backround image because of the slight lighting effect. (It's brighter in the middle, it you look closely. In IB, I have the nav bar set to Black Transparent with the following Background Image. (320 x 44px)
h file.
IBOutlet UINavigationBar *navBar;
m file "viewDidLoad" function:
navBar.backgroundColor = [UIColor colorWithPatternImage:[UIImage imageNamed:#"nav"]];
In iOS < 5 you can set tint color of individual navigation bar directly, e.g.:
// self is a UIViewController
[self.navigationController.navigationBar setTintColor:[UIColor purpleColor]];
Once you don't need compatibility with iOS 4.x you can use appearance proxy for UINavigationBar. This would work for all navigation bars in the application:
[[UINavigationBar appearance] setTintColor:[UIColor purpleColor]];
I have some items that change the UINavigationBar color when the detail pages are accessed. My issue is getting back to the default UINavigationBar color. What color is it? It is not blue or gray for sure.
Also when going "back", where is the best place to put this color change? Unload does not seem to work for this. On the table view controller, Placing the color change at the end of the "didSelectRowAtIndexPath" changes it prematurely.
What is the default UINavigationBar color?
Where should I place the change when the user is leaving the detail view?
I think you can just set the navigation bar color to nil and it will revert to its default.
Color : [[UINavigationBar appearance] setBarTintColor:[UIColor blackColor]];
Image : [[UINavigationBar appearance] setBackgroundImage:[UIImage imageNamed:#"navigationBar_320X44.png"] forBarMetrics:UIBarMetricsDefault];
