I got this image that I want to use in my navigation controller:
I'm setting it like this(following advice from this question):
UINavigationBar *theBar = self.navigationController.navigationBar;
if ( [theBar respondsToSelector:#selector(setBackgroundImage:forBarMetrics:)] ) {
UIImage *image = [UIImage imageNamed:#"cabecalho.jpg"];
[theBar setBackgroundImage:image forBarMetrics:UIBarMetricsDefault];
}
But when I run my app, I get this:
What do I do so my image can fit the navigation controller?
Thank you.
Try with following code
[self.navigationBar setBackgroundColor:[UIColor colorWithPatternImage:[UIImage imageNamed:#"myImage.png"]]];
Refer How to add background image on iphone Navigation bar? this question that may be helpful for you.
I found the solution following the example of this question.
When I create my UINavigationController, I do this:
UINavigationController *nav = [[UINavigationController alloc] initWithRootViewController:viewLista];
if ([nav.navigationBar respondsToSelector:#selector(setBackgroundImage:forBarMetrics:)] ) {
UIImage *image = [UIImage imageNamed:#"cabecalho.png"];
[nav.navigationBar setBackgroundImage:image forBarMetrics:UIBarMetricsDefault];
}
I have set a custom navigationbar in my appdelegate. You can see the code over here.
UIImage *image = [UIImage imageNamed:#"navbar.png"];
[[UINavigationBar appearance] setBackgroundImage:image forBarMetrics:UIBarMetricsDefault];
But now I'm working with the eventkit framework. What I want is when I go to eventdetails, that I get the standard navbar layout.So without the image.
EKEventViewController *vc = [[EKEventViewController alloc] init];
[vc.navigationController.navigationBar setBackgroundImage:nil forBarMetrics:UIBarMetricsDefault];
vc.event = [dataSource eventAtIndexPath:indexPath];
vc.allowsEditing = YES;
[calendar.navigationController pushViewController:vc animated:YES];
I've tried the following but it is not working.
Any help?
you can do one thing, take the screenshot of one viewController with default navigation bar , just crop only navigation bar area i.e. make image of 320 x 44 size.
when you want again your by default navigation bar , that time use this cropped image as background of navigation bar ,add following code
UIImage *image = [UIImage imageNamed:#"defaultNavbar.png"];
[[UINavigationBar appearance] setBackgroundImage:image forBarMetrics:UIBarMetricsDefault];
again when you navigate to another viewController having custom Navimage then again draw nav image by help of your custom image code i.e.
UIImage *image = [UIImage imageNamed:#"navbar.png"];
[[UINavigationBar appearance] setBackgroundImage:image forBarMetrics:UIBarMetricsDefault];
I am using UITabBarController and want to add image to it, a whole image to tab bar, not to any tab item. Is it possible, can anyone guide.
Thanks in advance.
Try this. May be it help
UIImage *tabBackground = [[UIImage imageNamed:#"Your Image"]
resizableImageWithCapInsets:UIEdgeInsetsMake(0, 0, 0, 0)];
// Set background for all UITabBars
[[UITabBar appearance] setBackgroundImage:tabBackground];
// Set background for only this UITabBar
[[tabBarController tabBar] setBackgroundImage:tabBackground];
If you are using iOS 5 or greater you can use setBackgroundImage:
UITabBar *yourtabBar = [yourtabController tabBar];
[yourtabBar setBackgroundImage:[UIImage imageNamed:#"tabbar.jpg"]];
How can I change the background image of UIToolbar? I have been able to do this for navigation bar, but not UIToolbar. I do not want to change tintColor. I would like to change the whole image.
Thanks for your help.
From Can I give a UIToolBar a custom background in my iPhone app?
Overriding the drawRect function and creating an implementation of the UIToolbar does the trick :)
#implementation UIToolbar (CustomImage)
- (void)drawRect:(CGRect)rect {
UIImage *image = [UIImage imageNamed: #"nm010400.png"];
[image drawInRect:CGRectMake(0, 0, self.frame.size.width, self.frame.size.height)];
}
#end
You could use the following code:
[myToolbar insertSubview:[[[UIImageView alloc] initWithImage:[UIImage imageNamed:#"toolbar_40.png"]] autorelease] atIndex:0];
Fixed for Simulator 4.3.
since iOS5 you can use the Appearance API:
[[UIToolbar appearance] setBackgroundImage:[UIImage imageNamed:#"someImage"] forToolbarPosition:UIToolbarPositionAny barMetrics:UIBarMetricsDefault];
I'd like an image to take up all of a navigation bar. This is the navigation that comes with a navigation based app. It appears on the RootViewController with the accompanying UITableView. I've seen some examples of how this might work.
Set navigation bar title:
UIImage *image = [UIImage imageNamed:#"TableviewCellLightBlue.png"];
UIImageView *imageView = [[UIImageView alloc] initWithImage:image];
[self.navigationController.navigationBar.topItem setTitleView:imageView];
The problem there is it only covers the title rather than the entire navigation bar.
There is also this thread: http://discussions.apple.com/message.jspa?messageID=9254241#9254241. Towards the end, the solution looks to use a tab bar, which I'm not using. It is that complicated to set a navigation bar background? Is there some other simpler technique?
I'd like to have a background for the navigation and still be able to use title text.
In your case, this solution found in another answer would work well.
With the "CustomImage" category added to UINavigationBar,
you can then just call:
UINavigationBar *navBar = self.navigationController.navigationBar;
UIImage *image = [UIImage imageNamed:#"yourNavBarBackground.png"];
[navBar setBackgroundImage:image];
This code should go in the method
- (void)viewWillAppear:(BOOL)animated
of the view controller where you want to have the custom image.
And, in that case you should better call:
[navBar clearBackgroundImage]; // Clear any previously added background image
before setBackgroundImage (otherwise it will be added multiple times...)
its changed for ios6, to make it work in ios 6 use:
UINavigationBar *navBar = self.navigationController.navigationBar;
UIImage *image = [UIImage imageNamed:#"image.png"];
[navBar setBackgroundImage:image forBarMetrics:UIBarMetricsDefault];
UIImage *image = [UIImage imageNamed:#"YourImage.png"];
UIImageView *imageView = [[UIImageView alloc] initWithImage:image];
[self.navigationController.navigationBar addSubview:imageView];
There is actually a much easier way to add a background image to any UIView class or subclass. It requires no class categorization or extension (subclassing), and you can do this on an "as needed" basis. For example, to add a background image to a view controller's navigation bar, do the following:
self.navigationController.navigationBar.layer.contents = (id)[UIImage
imageNamed:#"background.png"].CGImage;
You'll need to remember to add the Quartz Core framework to your project and add #import <QuartzCore/QuartzCore.h> wherever you need to do this. This is a much cleaner, simpler way to alter the drawing layer of anything that inherits from UIView. Of course, if you want to accomplish a similar effect for all navigation bars or tab bars, then subclassing makes sense.
UIImage *logo = [UIImage imageNamed:#"my_logo"];
UIImageView *logoView = [[UIImageView alloc]initWithImage:logo];
logoView.frame = CGRectMake(0, 0, 320, 37);
UINavigationController *searchNavCtrl = [[UINavigationController alloc] initWithRootViewController:searchViewController];
searchNavCtrl.navigationBar.barStyle = UIBarStyleBlack;
//searchNavCtrl.navigationItem.titleView = logoView;
//[searchNavCtrl.navigationController.navigationBar.topItem setTitleView:logoView];
[searchNavCtrl.navigationBar addSubview:logoView];
[logoView release];
Just add this line .
[self.navigationController.navigationBar setBackgroundImage:[UIImage imageNamed:#"NavBar.png"] forBarMetrics:UIBarMetricsDefault];
Bam! One line and done.
I used cmp's solution and added some logic to remove it as I only wanted a custom background image on home screen within on view appear.
HomeViewController.m
UIImage *image = [UIImage imageNamed:#"HomeTitleBG.png"];
UIImageView *imageView = [[UIImageView alloc] initWithImage:image];
imageView.tag = 10;
UIImageView *testImgView = (UIImageView *)[self.navigationController.navigationBar viewWithTag:10];
if ( testImgView != nil )
{
NSLog(#"%s yes there is a bg image so remove it then add it so it doesn't double it", __FUNCTION__);
[testImgView removeFromSuperview];
} else {
NSLog(#"%s no there isn't a bg image so add it ", __FUNCTION__);
}
[self.navigationController.navigationBar addSubview:imageView];
[imageView release];
I also tried to use the suggested clearBackgroundImage method but couldn't get it to work so I gave the image a tag and then removed it in the other viewcontrollers on view will appear.
OtherViewController.m
UIImageView *testImgView = (UIImageView *)[self.navigationController.navigationBar viewWithTag:10];
if ( testImgView != nil )
{
NSLog(#"%s yes there is a bg image so remove it", __FUNCTION__);
[testImgView removeFromSuperview];
}
`
just go the view controller and paste in super viewdidload
and replace your image in mainlogo and then set the navigation title in set your image logo
- (void)viewDidLoad
{
[super viewDidLoad];
//set your image frame
UIImageView *image=[[UIImageView alloc]initWithFrame:CGRectMake(0,0,70,45)] ;
//set your image logo replace to the main-logo
[image setImage:[UIImage imageNamed:#"main-logo"]];
[self.navigationController.navigationBar.topItem setTitleView:image];
}
