I am giving the same background color for both Navigation bar and Status bar for ios 6 using my below code. But i don't know why i am getting 1 pixel of separator line as i have mentioned in my attached screenshot. Can you please help me how can i remove this line?
here is my code for App Delegate:
//For changing status bar background color
self.window.backgroundColor = [UIColor colorWithRed:(51/255.0) green:(51/255.0) blue:(51/255.0) alpha:1.0]];
[[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleLightContent];
[[UIApplication sharedApplication] setStatusBarHidden:NO withAnimation:UIStatusBarAnimationNone];
//For changing navigation bar background color
[[UINavigationBar appearance] setBackgroundColor:[UIColor colorWithRed:(51/255.0) green:(51/255.0) blue:(51/255.0) alpha:1.0]];
[[UINavigationBar appearance] setTintColor:[UIColor colorWithRed:(51/255.0) green:(51/255.0) blue:(51/255.0) alpha:1.0]];
[[UINavigationBar appearance] setBackgroundImage:[[UIImage alloc] init] forBarMetrics:UIBarMetricsDefault];
[[UINavigationBar appearance] setShadowImage:[[UIImage alloc] init]];
Thanks in advance.

I have updated my Xcode into 13, later on words in my old project navigation and tab bars colours was changed to transparent.
My Code is
[[UINavigationBar appearance] setBarTintColor:[UIColor AppThemeColour]];
[[UINavigationBar appearance] setTintColor:[UIColor whiteColor]];
[[UINavigationBar appearance] setTranslucent:NO];
[[UINavigationBar appearance] setShadowImage:[[UIImage alloc] init]];
I tried to add background colour but title and images of the navigationBar not appering.
self.navigationController.navigationBar.backgroundColor = [UIColor bOneAppThemeColor];
[[UINavigationBar appearance] setBarTintColor:[UIColor AppThemeColour]];
[[UINavigationBar appearance] setTintColor:[UIColor whiteColor]];
[[UINavigationBar appearance] setTranslucent:NO];
[[UINavigationBar appearance] setShadowImage:[[UIImage alloc] init]];
I have studied this below link but i'm unable to implement it in Objective C

Almost everything you're doing is wrong (and has been wrong for several years). You need to use UINavigationBarAppearance (and UITabBarAppearance) and apply them to both the bar's standardAppearance and its scrollEdgeAppearance. Set the appearance's background color, not its tint color. And do not touch the translucent property ever.
In this simple example, we make all navigation bars adopt your theme color. Modify to suit your needs and desires:
if (#available(iOS 13.0, *)) {
UINavigationBarAppearance* appear = [UINavigationBarAppearance new];
appear.backgroundColor = [UIColor AppThemeColor];
id proxy = [UINavigationBar appearance];
[proxy setStandardAppearance: appear];
[proxy setScrollEdgeAppearance: appear];
} else {
// Fallback on earlier versions
}
In my view controller I can set my bar button item like this
[self.navigationItem.backBarButtonItem setTintColor:[UIColor whiteColor]];
But what I want to achieve is to set it in my app delegate so that all my bar button items on all view controllers are white something similar to doing this
[[UINavigationBar appearance] setTintColor:[UIColor whiteColor]];
I can get it to work on text but I want to change it for images
Sample Image,
Edited:
How I set my image
You can use the same strategy to change the UINavigationBar barTintColor and titleTextAttributes:
[[UINavigationBar appearance] setTintColor:[UIColor whiteColor]]; // this will change the back button tint
[[UINavigationBar appearance] setBarTintColor:[UIColor redColor]];
[[UITabBarItem appearance] setTitleTextAttributes:#{ NSForegroundColorAttributeName : [UIColor whiteColor]
forState:UIControlStateSelected];
Edited:
UIImage *selectedImage = [[UIImage imageNamed:#"selectedImage"] imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal];
// Make in Appdelegate.h
#property(nonatomic)UIColor* appDelColor;
AppDelegate *appDelegate = (AppDelegate *)[[UIApplication sharedApplication] delegate];
// set AppDelegate Color
appDelegate.appDelColor= [UIColor redColor];
//get AppDelegate Color
UIColor *appDELColor=appDelegate.appDelColor;
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
[UINavigationBar appearance].tintColor = [UIColor whiteColor];
return YES;
}
May this will help you.. :)
In my iOS application, I am using the DocumentInteractionController to preview the .csv document.
self.documentController = [UIDocumentInteractionController interactionControllerWithURL:fileLocation];
[self.documentController setDelegate:self];
[self.documentController presentPreviewAnimated:YES];
However, I am finding that the navigation bar is completely transparent. The back button is white, so it is not visible due to the white background.
Note that I have styled the navigation bar in the AppDelegate:
[[UINavigationBar appearance] setBarTintColor:[UIColor colorWithRed:0/255.0f green:138/255.0f blue:188/255.0f alpha:1.0f]];
[[UINavigationBar appearance] setTintColor:[UIColor whiteColor]];
[[UINavigationBar appearance] setTitleTextAttributes:#{NSFontAttributeName:[UIFont fontWithName:#"DINPro-Bold" size:17]}];
[[UINavigationBar appearance] setBackgroundImage:[[UIImage alloc] init] forBarPosition:UIBarPositionAny barMetrics:UIBarMetricsDefault];
[[UINavigationBar appearance] setShadowImage:[UIImage imageNamed:#"shadow"]];
[[UITabBar appearance] setSelectedImageTintColor:[UIColor whiteColor]];
[[UITabBar appearance] setTintColor:[UIColor whiteColor]];
[[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleLightContent animated:NO];
Essentially, my question is how can I make the appearance of the navigation bar in the DocumentInteractionController View Controller consistent with the appearance of the navigation bar throughout the entire app (or at least visible!).
This line puts a transparent (or rather void) background image to your UINavigationBar. Why is that?
[[UINavigationBar appearance] setBackgroundImage:[[UIImage alloc] init] forBarPosition:UIBarPositionAny barMetrics:UIBarMetricsDefault];
Just remove the line and everything works well.
If you want to set a shadow image, then you should think about using appearanceWhenContainedIn: instead of appearance so it won't spread to unhandled controllers.
As for the Status Bar Style, the simplest way would be to pass self.navigationController as the presenter, instead of self:
- (UIViewController *) documentInteractionControllerViewControllerForPreview: (UIDocumentInteractionController *) controller {
return self.navigationController;
}
Hope this will help,
I'm doing some changes to the Navigationbar with appearance in appdelegate.
This is my method:
-(void) setAppearance{
NSMutableDictionary *titleBarAttributes = [NSMutableDictionary dictionaryWithDictionary: [[UINavigationBar appearance] titleTextAttributes]];
[titleBarAttributes setValue:[UIFont fontWithName:#"AvantGarde-ExtraLight" size:18] forKey:NSFontAttributeName];
[titleBarAttributes setValue:[UIColor whiteColor] forKey:NSForegroundColorAttributeName];
[[UINavigationBar appearance] setTitleTextAttributes:titleBarAttributes];
[[UINavigationBar appearance] setBarTintColor:[UIColor colorWithRed:6.0/256.0 green:57.0/256.0 blue:84.0/256.0 alpha:1.0]];
[[UINavigationBar appearance] setTintColor:[UIColor whiteColor]];
int borderSize = 3;
UIImageView *navBorder = [[UIImageView alloc] initWithFrame:CGRectMake(0,
41,
320,
borderSize)];
navBorder.image = [UIImage imageNamed:#"energy_line"];
navBorder.tag = 999;
[[UINavigationBar appearance] addSubview:navBorder];
[[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleLightContent];
}
I have a method in my appdelegate that sets the window to my first viewController, when i call this method, my navBorder is removed from the navigationbar. I don't understand why this happens, there is no code that changes anything in my navigationbar in the viewcontroller.
- (void)rootView
{
[self.window setRootViewController:initialViewController];
}
I answered pretty much the same question here: https://stackoverflow.com/a/26414437/538491
But here is a summary:
Calling [[UINavigationBar appearance] returns an appearance proxy for the receiver class. The addSubview: method is not tagged as UI_APPEARANCE_SELECTOR. One major downside to UIAppearance's proxy approach is that it's difficult to know which selectors are compatible.
You should get a hold of the navigation bar and add the image there by calling this method: [self.navigationController.navigationBar addSubview:navBorder] or you should subclass UINavigationBar which gives you more flexibility.
I am using MFMailComposeViewController.I can't add navigationBar background image to MFMailComposeViewController on ios7.My Code working ios7 before .But doesn't work on ios7.How can I add navigationbar background image to MFMailComposeViewController on ios7?
MFMailComposeViewController *mailCompose = [[MFMailComposeViewController alloc] init];
mailCompose.mailComposeDelegate = self;
[mailCompose setSubject:#"SubjectName"];
[mailCompose setMessageBody:shareBodyString isHTML:NO];
if ([self respondsToSelector:#selector(presentViewController:animated:completion:)])
{
[self presentViewController:mailCompose animated:YES completion:nil];
}
else {
[self presentModalViewController:mailCompose animated:YES];
}
[mailCompose.topViewController.navigationController.navigationBar setBackgroundImage:[UIImage imageNamed:#"navigationbar-background.png"] forBarMetrics:UIBarMetricsDefault]; // working before ios7
Use the Appearance Proxy. Following code will target the whole application :
UINavigationBar *navBar = [UINavigationBar appearance];
[navBar setBackgroundImage:[UIImage imageNamed:#"navigationbar-background.png"] forBarMetrics:UIBarMetricsDefault];
If you prefer to target only in MFMailComposeViewController change the first line with this :
navBar = [UINavigationBar appearanceWhenContainedIn:[MFMailComposeViewController class], nil];
If you already customised navigation bar and also want it to apply MFMailComposeViewController, It only allows to do it with UIAppearance proxy. For iOS 7.1.1, i replaced navigation bar background but couldn't change status bar background. Also it greyed out bar button items on subsequent calls. Therefore I stop customising and tried to turn back to default navigation bar style before creating MFMailComposeViewController
[[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleDefault];
[[UINavigationBar appearance] setBarStyle:UIBarStyleDefault];
[[UINavigationBar appearance] setTintColor:nil];
[[UINavigationBar appearance] setTitleTextAttributes:[NSDictionary dictionaryWithObjectsAndKeys:[UIColor blackColor],NSForegroundColorAttributeName,[UIFont fontWithName:#"Helvetica-Bold" size:18.0], NSFontAttributeName, nil]];
MFMailComposeViewController *mailComposer =[[MFMailComposeViewController alloc] init];
