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 very new to iOS programming.
I'm trying to set the toolbar background to a custom image.
I'm also using storyboards.
How do I go about that?
Do I edit UIToolbar in the UI Kit framework? Do I need to change something in Storyboard?
Thanks,
You can use UIToolbar's built-in -setBackgroundImage:forToolbarPosition:barMetrics: method:
// portrait
[yourToolbar setBackgroundImage:[UIImage imageNamed:#"YourToolbarBkg-Portrait.png"] forToolbarPosition:UIToolbarPositionAny barMetrics:UIBarMetricsDefault];
// landscape
[yourToolbar setBackgroundImage:[UIImage imageNamed:#"YourToolbarBkg-Landscape.png"] forToolbarPosition:UIToolbarPositionAny barMetrics: UIBarMetricsLandscapePhone];
YourToolbarBkg-Portrait.png will be 320x44 bkg image for portrait mode
YourToolbarBkg-Landscape.png will be 480x32 bkg image for landscape mode.
UIToolbar inherits from UIView. This just worked for me:
[topBar insertSubview:[[[UIImageView alloc] initWithImage:[UIImage imageNamed:BAR_BKG_IMG]] autorelease] atIndex:0];
UPDATED
topBar ------ is the outlet of the UIToolBar u are using
use this code where u are creating ur UIToolBar the class which implements the UIToolbar..
plus tell me y r u using Toolbar whats ur main purpose for it
Instead of editing UIToolBar, why not create a UIView of the same size and skin that however you would like? That would be easier if you are new.
Or if you want to override UIToolbar:
#implementation UIToolbar (CustomImage)
- (void)drawRect:(CGRect)rect {
UIImage *image = [UIImage imageNamed: #"image.png"];
[image drawInRect:CGRectMake(0, 0, self.frame.size.width, self.frame.size.height)];
}
#end
Had a right faff with background images for ToolBars and NavBars. I know setting the background image of a NavBar and ToolBar is generally a doddle. But, when you're presenting modal VC's, for some insane reason, where a NavBar is being added and you DO change the background image, it appears to double in size. Altering the height has strange results.
My issue was where I was using a NavController all over my App, but needed a modal view for one or two aspects of it. Simple enough. However, I needed either a NavBar or ToolBar type header with a Done button to pop the VC off the stack. Again, not an issue. But I needed the NavBar or ToolBar to look the same as everywhere else in my App.
I settled on a ToolBar, seeing as the VC was being presented modally. So, there my ToolBar sat, in typical Apple-blue. Nice, but not how the rest of my App looked, where a blackened image was being used for each NavBar. Using the iOS 5 appearance proxy, I altered the background image of the ToolBar. And this worked. But, unless I had the UIImage in exactly the proportions and size expected by the Tool Bar, I was in a pickle. The image simply did not look right at all. So, I decided to create a UIIMageView, where I could control the content mode, then insert a subview onto the toolBar.
Take a look at my code below.
UIImageView *toolbarImageView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:NAV_BAR_BACKGROUND]];
[toolbarImageView setFrame:[self.IBOToolBar bounds]];
[toolbarImageView setContentMode:UIViewContentModeScaleAspectFill];
[self.IBOToolBar insertSubview:toolbarImageView atIndex:1];
It's a bit of a fluff but I do hope this helps someone alter the image on their ToolBar.
NAV_BAR_BACKGROUND can be defined as follows:
#define NAV_BAR_BACKGROUND #"navBarBlackMattDarkSquare.png"
I am setting global styles in iOS 5 with UIAppearance. Here's an example:
[[UIbarButtonItem appearance]
setTtitletextAttributes:someStyle
forState:UIControlStateNormal
];
It looks good in most cases:
But there are cases where the global style looks ugly, like in a movie player.
For the movie player, I would prefer to have the default blue button. So how would I target only the back button's appearance and not the done button's appearance? I have similar issues with targeting normal table cells and grouped table cells.
You need to use a custom subclass of UINavigationBar. Let's call it MyNavigationBar. Then you can do this:
[[UIBarButtonItem appearanceWhenContainedIn:[MyNavigationBar class], nil]
setTintColor:[UIColor redColor]];
and it will only affect buttons within your navigation bar, not the MPMoviePlayerController's navigation bar.
The problem, of course, is that UINavigationController always uses a basic UINavigationBar... if you create it in code. But if you create it in a nib, you can click on its navigation bar (in the nib's document outline) and change the bar's class in the Identity inspector.
If in your AppDelegate you just replace
[[UINavigationBar appearance] setBackgroundImage:[UIImage imageNamed:#"navback"]
forBarMetrics:UIBarMetricsDefault];
with
[[UINavigationBar appearanceWhenContainedIn:[UINavigationController class], nil]
setBackgroundImage:[UIImage imageNamed:#"navback"] forBarMetrics:UIBarMetricsDefault];
movie player will have proper black bar in full screen mode. Works in iOS 5 and iOS 6
You can actually change the proxy to just target certain view hierarchies. In other words, when the view you want to customize is contained in a certain view, you can modify its appearance differently from the rest. So set your global (white) style first, but then call the following method to customize the appearance for when the button appears in an MPMoviePlayerController or whatever else.
[[UIBarButtonItem appearanceWhenContainedIn:
[MPMoviePlayerController class], nil]
setTitletextAttributes:someStyle
forState:UIControlStateNormal];
Let me know if that helps!
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.
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];
