IOS 7 Navigation Bar text and arrow color

问题:

I want to set background for Navigation Bar to be black and all colors inside it to be white.

So, I used this code :

[[UINavigationBar appearance] setTitleTextAttributes:      [NSDictionary dictionaryWithObjectsAndKeys:       [UIColor whiteColor],       NSForegroundColorAttributeName,       [UIColor whiteColor],       NSForegroundColorAttributeName,       [NSValue valueWithUIOffset:UIOffsetMake(0, -1)],       NSForegroundColorAttributeName,       [UIFont fontWithName:@"Arial-Bold" size:0.0],       NSFontAttributeName,       nil]]; 

But back button text color, arrow and bar button have still default blue color.
How to change those colors like on image below?

Behavior from some of the properties of UINavigationBar has changed from iOS 7. You can see in the image shown below :

Apple Documentation for barTintColor says :

This color is made translucent by default unless you set the translucent property to NO.

Sample Code :

self.navigationController.navigationBar.barTintColor = [UIColor blackColor]; self.navigationController.navigationBar.tintColor = [UIColor whiteColor]; [self.navigationController.navigationBar   setTitleTextAttributes:@{NSForegroundColorAttributeName : [UIColor whiteColor]}]; self.navigationController.navigationBar.translucent = NO;

This one took me about half a day to figure out but this is what worked for me. Inside the rootViewController that initializes the navigationController, I put this code inside my viewDidAppear method:

//set bar color [self.navigationController.navigationBar setBarTintColor:[UIColor colorWithRed:85.0/255.0 green:143.0/255.0 blue:220.0/255.0 alpha:1.0]]; //optional, i don't want my bar to be translucent [self.navigationController.navigationBar setTranslucent:NO]; //set title and title color [self.navigationItem setTitle:@"Title"]; [self.navigationController.navigationBar setTitleTextAttributes:[NSDictionary dictionaryWithObject:[UIColor whiteColor] forKey:UITextAttributeTextColor]]; //set back button color [[UIBarButtonItem appearanceWhenContainedIn:[UINavigationBar class], nil] setTitleTextAttributes:[NSDictionary dictionaryWithObjectsAndKeys:[UIColor whiteColor], UITextAttributeTextColor,nil] forState:UIControlStateNormal]; //set back button arrow color [self.navigationController.navigationBar setTintColor:[UIColor whiteColor]];

Swift3, ios 10

To globally assign the color, in AppDelegate didFinishLaunchingWithOptions:

let textAttributes = [NSForegroundColorAttributeName:UIColor.white] UINavigationBar.appearance().titleTextAttributes = textAttributes 

Swift 4, iOS 11

let textAttributes = [NSAttributedStringKey.foregroundColor:UIColor.white] UINavigationBar.appearance().titleTextAttributes = textAttributes

Vin's answer worked great for me. Here is the same solution for C# developers using Xamarin.iOS/MonoTouch:

var navigationBar = NavigationController.NavigationBar; //or another reference navigationBar.BarTintColor = UIColor.Blue; navigationBar.TintColor = UIColor.White; navigationBar.SetTitleTextAttributes(new UITextAttributes() { TextColor = UIColor.White }); navigationBar.Translucent = false; 

回答5:

[[UINavigationBar appearance] setTitleTextAttributes:@{NSForegroundColorAttributeName : [UIColor whiteColor]}]; 

回答6:

Swift / iOS8

let textAttributes = NSMutableDictionary(capacity:1) textAttributes.setObject(UIColor.whiteColor(), forKey: NSForegroundColorAttributeName) navigationController?.navigationBar.titleTextAttributes = textAttributes 

回答7:

To change color of UINavigationBar title the correct way use this code:

[self.navigationController.navigationBar setTitleTextAttributes:[NSDictionary dictionaryWithObject:[UIColor whiteColor] forKey:UITextAttributeTextColor]]; 

UITextAttributeTextColor is deprecated in lastest ios 7 version. Use NSForegroundColorAttributeName instead.

回答8:

If you're looking to change the title text size and the text color you have to change the NSDictionary titleTextAttributes, for 2 of its objects:

    self.navigationController.navigationBar.titleTextAttributes = [NSDictionary dictionaryWithObjectsAndKeys:[UIFont fontWithName:@"Arial" size:13.0],NSFontAttributeName,                                                                   [UIColor whiteColor], NSForegroundColorAttributeName,                                                                    nil];

I think previous answers are correct , this is another way of doing the same thing. I am sharing it here with others just in case if it becomes useful for someone. This is how you can change the text/title color for the navbar in ios7:

UIColor *red = [UIColor colorWithRed:254.0f/255.0f green:0.0f/255.0f blue:0.0f/255.0f alpha:1.0]; NSMutableDictionary *navBarTextAttributes = [NSMutableDictionary dictionaryWithCapacity:1]; [navBarTextAttributes setObject:red forKey:NSForegroundColorAttributeName ]; self.navigationController.navigationBar.titleTextAttributes = navBarTextAttributes; 

回答10:

It seems that Accessibility controls in the iOS Settings override pretty much everything you try to do color-wise to the navigation bar buttons. Make sure you have all the settings to the default positions (set increase contrast, bold text, button shapes, etc to off) otherwise you won't see anything change. Once I did it, all the color change code started working as expected. You might not need to turn them all off, but I didn't pursue it further.
