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;

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 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]];
I am trying to center a UIImageView in a scroll view. Here is the code I tried with no results.
UIImageView *iv = [[UIImageView alloc] initWithImage:[UIImage imageNamed:kReceiptDetailScrollViewBackgroundCornered]];
[iv setContentMode:UIViewContentModeCenter];
[[self scrollView] insertSubview:iv atIndex:0];
Anybody know what's wrong with this?
You set the image view's content mode to center, which means that the image is not scaled and it can be larger than the image view that displays it.
UIImage *image = [UIImage imageNamed: kReceiptDetailScrollViewBackgroundCornered];
UIImageView *iv = [[UIImageView alloc] initWithImage: image];
iv.contentMode = UIViewContentModeScaleAspectFit;
iv.frame = [self scrollView].bounds;
[[self scrollView] addSubview: iv];
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];
I have the following in my Navigation Controller Load event...
UIImage *image = [UIImage imageNamed:#"Background.jpg"];
CGImageRef cgImg = CGImageCreateWithImageInRect(image.CGImage, CGRectMake(0, 0, 500, 620));
UIImage* part = [UIImage imageWithCGImage:cgImg];
UIImageView* imageView = [[UIImageView alloc] initWithImage:part];
[self.view insertSubview:imageView atIndex:0];
This sets the background image and works fine once I have set the embedded view to have a clear background. My question is how do I alter this image once it is loaded?
The effect I am looking for is that I want to crop a new section of the image when different views are pushed onto the stack.
I know I could load a new image for each table but the desired effect I want is so that when you push to the next view, the table moves from right to left showing the new table, but the background moves right to left only a little bit.
Ended up using NSTimer and this combined
[[self.navigationController.view.subviews objectAtIndex:0] removeFromSuperview];
[self.navigationController.view insertSubview:imageView atIndex:0];
Use tag to different your backgroundView and other views
#deifne BACKGROUNDVIEWTAG 999
if(![self.view subviews] || ((UIView *)[[self.view subviews] objectAtIndex:0]).tag != BACKGROUNDVIEWTAG)
{
UIImage *image = [UIImage imageNamed:#"Background.jpg"];
CGImageRef cgImg = CGImageCreateWithImageInRect(image.CGImage, CGRectMake(0, 0, 500, 620));
UIImage* part = [UIImage imageWithCGImage:cgImg];
UIImageView* imageView = [[UIImageView alloc] initWithImage:part];
imageView.tag = BACKGROUNDVIEWTAG;
[self.view insertSubview:imageView atIndex:0];
}
