So I am try to set a background image for a navigation bar in MonoTouch. The image will be the same everywhere. How would i do this?
In the viewdid load: NavBar.SetBackgroundImage(UIImage.FromFile ("btn-title-bar.png"));
doesn't work.
Try
[[UINavigationBar appearance] setBackgroundImage:[UIImage imageNamed:#"btn-title-bar.png"] forBarMetrics:UIBarMetricsDefault];
In c# land that is:
UINavigationBar.Appearance.SetBackgroundImage (UIImage.FromFile ("btn-title-bar.png"), UIBarMetrics.Default);
Try this below code.
UIImage *image = [UIImage imageNamed: #"NavigationBar#2x.png"];
UIImageView *imageView = [[UIImageView alloc] initWithImage: image];
imageView.frame = CGRectMake(0, 0, 320, 44);
[self.navigationController.navigationBar addSubview:imageView];
if you want to put different images on every page then write this method in view did load on every page..
UIImage *image = [UIImage imageNamed: #"logo.png"];
UIImageView *imageView = [[UIImageView alloc] initWithImage: image];
self.navigationItem.titleView = imageView;
and if u want single image on every page then write this code in delegate.m.
[[UINavigationBar appearance] setBackgroundImage:[UIImage imageNamed:#"logo.png"]
forBarMetrics:UIBarMetricsDefault];

Something weird and frustrating is happening with the UINavigationBar on iOS7. I'm trying to add an image like this:
[[UINavigationBar appearance] setBackgroundImage:[UIImage imageNamed:#"Logo_Small.png"] forBarMetrics:UIBarMetricsDefault];
The result is that the lettering of my header -- the Hebrew letters -- repeat all over the navigation bar.
I tried all four options for the UIBarMetrics flag, but with the other three the logo just disappears. I also set the image size to 320x64, as per the documentation. But nothing seems to do the right thing, and I'm on the verge of giving up using a logo and just have a controller.title.
Do the below:
UIImage *gradientImage = [[UIImage imageNamed:#"Logo_Small.png"] resizableImageWithCapInsets:UIEdgeInsetsMake(-4, 300, 10, 300)];// play here
[[UINavigationBar appearance] setBackgroundImage:gradientImage forBarMetrics:UIBarMetricsDefault];
you can do like this
UIImageView *iv = [[UIImageView alloc] initWithFrame:CGRectMake(0,0,320,44)];
iv.image = [UIImage imageNamed:#"Logo_Small.png"];
self.navigationItem.titleView = iv;
Use this,
UIImage *navBarImage64 = [[UIImage imageNamed:#"Logo_Small.png"] resizableImageWithCapInsets:UIEdgeInsetsMake(0, 0, 0, 0)];
[[UINavigationBar appearance] setBackgroundImage:navBarImage64 forBarMetrics:UIBarMetricsDefault];
If above is not working then add imageview in your NavigationBar as below code. it work.
UIImage *image = [UIImage imageNamed: #"NavigationBar#2x.png"];
UIImageView *imageView = [[UIImageView alloc] initWithImage: image];
imageView.frame = CGRectMake(0, 0, 320, 44);
[self.navigationController.navigationBar addSubview:imageView];
You code is actually works. The problem is that you are probably calling it after UINavigationBar was added to screen.
To verify that your code is working you can try to put into AppDelegate's didiFinishedLaunchingWithOptions.
To customize navigation bar with Image use this,
[self.navigationController.navigationBar setBackgroundImage:[UIImage imageNamed:#"ImageName.png"] forBarMetrics:UIBarMetricsDefault];
I am using a UITabBarController in my application (for iPhone 5). When i am trying to set an image on the TabBAr, the image shows a line. I have seen two questions similar to mine, but did not understand the solution.
Here's how I am adding the image:
UIImageView *tabBarView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:#"tab_mypeople.png"]];
tabBarView.frame = CGRectMake(0, -15, 320, 64);
[tabBarController.tabBar addSubview:tabBarView];
The dimensions of my current image is 320X64 pixels.
How to resolve this issue??
write this in appdelegate.m didfinishLanching method
UIImage *tabBackground = [[UIImage imageNamed:#"tab_bg"]
resizableImageWithCapInsets:UIEdgeInsetsMake(0, 0, 0, 0)];
[[UITabBar appearance] setBackgroundImage:tabBackground];
[[UITabBar appearance] setSelectionIndicatorImage:[UIImage imageNamed:#"tab_select_indicator"]];
In iOS 6 and aboove the UITabBar has a shadow image, if you want to disable it you can just call yourTabBar.shadowImage = [UIImage new].
In your case tabBarController.tabBar.shadowImage = [UIImage new]
Yes, it is possible to make it exact size.
Use this code if you are just using a UITabBar inside your view:
Type :1
UITabBar *tabBar = [[UITabBar alloc]initWithFrame:CGRectMake(0, 100, self.view.frame.size.width, 60)];
[self.view addSubview:tabBar];
UIImageView *tabBarView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:#"tabBar.png"]];
tabBar.backgroundImage = tabBarView.image;
Presently my image size is 320 x 5
Type 2:
If you are using a UITabBarController then use it like this
UIImageView *tabBarView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:#"tabBar.png"]];
UITabBarController *tabController = [[UITabBarController alloc]init];
tabController.tabBar.backgroundImage = tabBarView.image;
Here are the screen shot for both.
Hi i used this code to set the background image for my bar button. I put it in "AppDelegate.h"
//-- set bar button image
UIImage *barButtonImage = [[UIImage imageNamed:#"bar-button"] resizableImageWithCapInsets:UIEdgeInsetsMake(0, 6, 0, 6)];
[[UIBarButtonItem appearance] setBackgroundImage:barButtonImage forState:UIControlStateNormal barMetrics:UIBarMetricsDefault];
It worked fine but in my Search Controller I dont want to use it, because it make my "search" button look very ugly. Is there anyway to remove the background image in search controller only ? Plz helpe me. Thanks!
In your SearchController.m try
[[UIBarButtonItem appearance] setBackgroundImage:nil forState:UIControlStateNormal barMetrics:UIBarMetricsDefault];
if you want to remove background image of Search controller
[[searchBar.subviews objectAtIndex:0] removeFromSuperview];
and you can add clear background image to it.
UIImageView *searchImage=[[UIImageView alloc] initWithFrame:CGRectMake(0.0, 0.0, 319.0, 44.0)];
[searchImage setImage:[UIImage imageNamed:#"searchbg.png"]];
[searchBar insertSubview:searchImage atIndex:1];
You can set where you want the customization, for instance in tis snippet I only want it in UINavigationBar.
[[UIBarButtonItem appearanceWhenContainedIn:[UINavigationBar class], nil]setBackgroundImage:barButtonImage forState:UIControlStateNormal barMetrics:UIBarMetricsDefault];
Not checked in xcode but the concept is OK. Here the doc + (instancetype)appearanceWhenContainedIn:(Class )ContainerClass,.... Great guide also here: NSHipster.
As you can see is a variadic arguments API, so you can set more classes
PS: I don't know if it is a wanted effect, but the kind of reflection is due to wrong insets in the image.
[searchBarObject setImage:nil forSearchBarIcon:UISearchBarIconSearch state:UIControlStateNormal];
This work for me.. I hope it will be helpful for you..
Updated full code..
.m file contents in viewDidLoad
//Table initialization..........................................................................
my_table = [[UITableView alloc]initWithFrame:CGRectMake(0, 0, 320, self.view.frame.size.height)];
//SearchBar initialization......................................................................
UISearchBar *search = [UISearchBar new];
[search sizeToFit];
search.delegate = self;
//Make the image in size 20x20................................................................
UIImage *img = [UIImage imageNamed:#"apple.jpg"];
UIGraphicsBeginImageContextWithOptions(CGSizeMake(20, 20), YES, 0);
[img drawInRect:CGRectMake(0, 0, 20, 20)];
UIImage *img2 = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();
//Set the image for the UISearchbarIconSearch...................................................
[search setImage:img2 forSearchBarIcon:UISearchBarIconSearch state:UIControlStateNormal];
search.barStyle = UIBarStyleBlackTranslucent;
[my_table setTableHeaderView:search];
[my_table reloadData];
//SearchDisplay initialization..................................................................
UISearchDisplayController *display = [[UISearchDisplayController alloc]initWithSearchBar:search contentsController:self];
sbc = display; //
display.delegate = self;
display.searchResultsDataSource = self;
display.searchResultsDelegate = self;
my_table.dataSource = self;
my_table.delegate = self;
[self.view addSubview:my_table];
.h file.
#interface ViewController : UIViewController<UITableViewDataSource, UITableViewDelegate, UISearchBarDelegate, UISearchDisplayDelegate>
{
NSArray *table_array;
UITableView *my_table;
UISearchDisplayController *sbc;
NSArray *filtered;
}
#end
This is my code which change the search icon image...
I want to insert an image to the navigation bar.
My code is
UINavigationBar *navBar = self.navigationController.navigationBar;
UIImage *image = [UIImage imageNamed:#"bodyBg.png"];
[navBar setBackgroundImage:image forBarMetrics:UIBarMetricsDefault];
I have attached the screenshot of the current output. Is this because of the large image size?
But my desired output is
First, make your navigation bar image size 1024x44 pixels nad for retina display 2048x88 pixels.
If you have the same image for UINavigationBar on every view controller, put this to AppDelegate in method didFinishLaunchingWithOptions:
[[UINavigationBar appearance] setBackgroundImage:[UIImage imageNamed:#"nav-background.png"] forBarMetrics:UIBarMetricsDefault];
// This will remove shadow in iOS6
if ([[UINavigationBar class] instancesRespondToSelector:#selector(shadowImage)]) {
[[UINavigationBar appearance] setShadowImage:[[[UIImage alloc] init] autorelease]];
}
And also I see you need custom back button, also put this in AppDelegate:
UIImage *backButtonNormal = [UIImage imageNamed:#"nav-back.png"];
[[UIBarButtonItem appearance] setBackButtonBackgroundImage:backButtonNormal forState:UIControlStateNormal barMetrics:UIBarMetricsDefault];
you can set the color of navigation bar same as your image use below code and you can put image name which you want to show in navigation bar
self.navigationController.navigationBar.tintColor = [UIColor colorWithPatternImage:[UIImage imageNamed:#"bodyBg.png"]];
try it out with this code..
if ([navBar respondsToSelector:#selector(setBackgroundImage:forBarMetrics:)])
{
[navBar setBackgroundImage:[UIImage imageNamed:#"Nav.png"] forBarMetrics:UIBarMetricsDefault];
}
else
{
UIImageView *imageView = (UIImageView *)[navBar viewWithTag:1];//any tag
if (imageView == nil)
{
imageView = [[UIImageView alloc] initWithImage:
[UIImage imageNamed:#"Nav.png"]];
[navBar insertSubview:imageView atIndex:0];
[imageView release];
}
}
see my full answer from this link setting-title-for-uinavigation-bar-in-iphone
self.navigationController.navigationBar.tintColor = [UIColor clearColor];
[self.navigationController.navigationBar setBackgroundImage:[UIImage imageNamed:#"navBar"] forBarMetrics:UIBarMetricsDefault];
I hope , it will work for u
Use UINavigationBar's setBackgroundImage: forBarMetrics: method :
[self.navigationController.navigationBar setBackgroundImage:yourImageHere forBarMetrics:UIBarMetricsDefault];
your UIImage should be of appropriate height and width. For example iphone 4 retina size would be 640*88 for portrait.
EDIT : Point here is if UIImage height is bigger say 150 pixel height it will display that much height and our UINavigationBar height is 44 pixel.
check this link for add background image in navigationbar and first you your navigationbar
image size set as navigationbar.
check this link here
i hope this code useful for you.
[myNavbar setBackgroundImage:[UIImage imageNamed: #"UINavigationBarBackground.png"]
forBarMetrics:UIBarMetricsDefault];
and also this link
Try this code it works for me:
UIView* navigationBGView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 320, 44)];
UIImage * targetImage = [UIImage imageNamed:#"Header_top.png"];
UIGraphicsBeginImageContextWithOptions(navigationBGView.frame.size, NO, 0.f);
[targetImage drawInRect:CGRectMake(0.f, 0.f, navigationBGView.frame.size.width, navigationBGView.frame.size.height)];
UIImage * resultImage = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();
navigationBGView.backgroundColor = [UIColor colorWithPatternImage:resultImage];
[self.navigationController.navigationBar addSubview:navigationBGView];
[self.navigationController.navigationBar setTintColor:[UIColor clearColor]];
Currently I'm trying to set a title image for my UINavigationBar, but it's stretching quite wide. I'm using the following code:
CGRect myImageRect = CGRectMake(0.0f, 0.0f, 40.0f, 20.0f);
UIImageView *myImage = [[UIImageView alloc] initWithFrame:myImageRect];
[myImage setImage:[UIImage imageNamed:#"titleImage.png"]];
self.navigationItem.titleView = myImage;
Does anybody have an idea as to why it's stretching so much width wise?
can you try setting the contentMode on either the navigationItem or the UIImageView?
myImage.contentMode = UIViewContentModeAspectFill;
Simply use following code it will set image to center of navigationbar..
UIImage *image = [UIImage imageNamed:#"sclogo.png"];
self.navigationItem.titleView = [[[UIImageView alloc] initWithImage:image] autorelease];
If you want to set image in full navigation bar than you can use follwoing code :-
UINavigationBar *navBar = self.navigationController.navigationBar;
UIImage *image = [UIImage imageNamed:#"youimage"];
[navBar setBackgroundImage:image forBarMetrics:UIBarMetricsDefault];
You are trying to set image in navigation bar title view.
Try this:
imageView.contentMode = UIViewContentModeScaleAspectFit;
