how do you change you navbar placeholder text color? also is there a light blue color for these messages?
[[UINavigationBar appearance] setBackgroundImage:[[UIImage alloc] init] forBarMetrics:UIBarMetricsDefault];
[[UINavigationBar appearance] setBackgroundColor:[UIColor redColor]];
Think this will work.
- (void)viewDidLoad
{
[super viewDidLoad];
//I am using UIColor BlueColor for an example but you can use whatever color you like
self.navigationController.navigationBar.titleTextAttributes = #{NSForegroundColorAttributeName: [UIColor blueColor]};
//change the title here to whatever you like
self.title = #"Home";
}

How to change the background color of navigationbar in iOS6 and iOS7 both?i want to know when to use setBarTintColor: method and when to use backgroundColor to change the background color of navigationbar.
Please tell me the difference between these two methods.
And a way to change the background color of navigationbar in both ios6 and ios7.
Thanks!!
self.navigationBar.barTintColor = [UIColor blueColor];
self.navigationBar.tintColor = [UIColor whiteColor];
self.navigationBar.translucent = NO;
// barTintColor sets the background color
// tintColor sets the buttons color
in ios6
[[UINavigationBar appearance] setBackgroundColor:[UIColor redColor]];
in ios7
navigationController.navigationBar.barTintColor = [UIColor greenColor];
or
[UINavigationBar appearance] setBarTintColor:[UIColor greenColor]];
try this...i have refered this link it supports for both iOS6 and iOS7
// Uncomment to change the background color of navigation bar
[[UINavigationBar appearance] setBarTintColor:UIColorFromRGB(0x067AB5)];
// Uncomment to change the color of back button
[[UINavigationBar appearance] setTintColor:[UIColor whiteColor]];
// Uncomment to assign a custom backgroung image
[[UINavigationBar appearance] setBackgroundImage:[UIImage imageNamed:#"nav_bg_ios7.png"] forBarMetrics:UIBarMetricsDefault];
// Uncomment to change the back indicator image
[[UINavigationBar appearance] setBackIndicatorImage:[UIImage imageNamed:#"back_btn.png"]];
[[UINavigationBar appearance] setBackIndicatorTransitionMaskImage:[UIImage imageNamed:#"back_btn.png"]];
// Uncomment to change the font style of the title
NSShadow *shadow = [[NSShadow alloc] init];
shadow.shadowColor = [UIColor colorWithRed:0.0 green:0.0 blue:0.0 alpha:0.8];
shadow.shadowOffset = CGSizeMake(0, 1);
[[UINavigationBar appearance] setTitleTextAttributes: [NSDictionary dictionaryWithObjectsAndKeys:
[UIColor colorWithRed:245.0/255.0 green:245.0/255.0 blue:245.0/255.0 alpha:1.0], NSForegroundColorAttributeName,
shadow, NSShadowAttributeName,
[UIFont fontWithName:#"HelveticaNeue-CondensedBlack" size:21.0], NSFontAttributeName, nil]];
you can use
NSArray *ver = [[UIDevice currentDevice].systemVersion componentsSeparatedByString:#"."];
if ([[ver objectAtIndex:0] intValue] >= 7) {
// iOS 7.0 or later
self.navigationController.navigationBar.barTintColor = [UIColor redColor];
self.navigationController.navigationBar.translucent = NO;
}else {
// iOS 6.1 or earlier
self.navigationController.navigationBar.tintColor = [UIColor redColor];
}
or
if (floor(NSFoundationVersionNumber) <= NSFoundationVersionNumber_iOS_6_1) {
// iOS 6.1 or earlier
self.navigationController.navigationBar.tintColor = [UIColor redColor];
} else {
// iOS 7.0 or later
self.navigationController.navigationBar.barTintColor = [UIColor redColor];
self.navigationController.navigationBar.translucent = NO;
}
}
barTintColor = Applies to the navigation bar background. This one is only available for iOS 7. For iOS 6, you can use the tintColor.
tintColor = Applies to the navigation items and bar button items.
Developer Reference
The navigationBar.barTintColor in my app is always black, and there is no way I can change it. I checked all classes and I never set it to black, but I do set it to UIColor clearColor. Still, the bar is black. Any suggestions?
Edit:I found out that the problem is with my [UIColor clearColor], when I change it to any other color it changes the color like it should, but clearColor makes it appear black.
Have a look there
Try modifying the Style and Translucent attributes on the navigation bar (top right in image).
If you are having problems modifying the status bar color, try adding this to your .plist (line below).
<key>UIViewControllerBasedStatusBarAppearance</key>
<false/>
Finally, here's some code you may want.
// Status bar color
[[UIApplication sharedApplication] setStatusBarStyle:yourStyle];
// Navigation bars color
[UINavigationBar appearance].barStyle = yourStyle;
[UINavigationBar appearance].barTintColor = [UIColor yourColor];
// Navigation bars items color
[UINavigationBar appearance].tintColor = [UIColor yourColor];
If its IOS7 try the code below
[[UINavigationBar appearance]setBarTintColor: [<Specify the UIColor you want>];
In IOS6 try this
[[UINavigationBar appearance] setTintColor: [<Specify the UIColor you want>];
Edit:
I think you have given
self.navigationController.navigationBar.barTintColor = [UIColor clearColor];
This will give black color. If you want any specific tint color, it must be specifed after clearing
self.navigationController.navigationBar.barTintColor = [UIColor clearColor];
self.navigationController.navigationBar.barTintColor = [UIColor <specify your color>];
if([[[UIDevice currentDevice] systemVersion] floatValue] < 7.0)
{
[[UINavigationBar appearance] setBackgroundImage:[UIImage imageNamed:#"nav_bg.png"] forBarMetrics:UIBarMetricsDefault];
[[UINavigationBar appearance] setTitleTextAttributes:
#{
UITextAttributeTextColor: [UIColor whiteColor],UITextAttributeTextShadowColor: [UIColor clearColor],UITextAttributeTextShadowOffset: [NSValue valueWithUIOffset:UIOffsetMake(0.0f, 1.0f)],UITextAttributeFont: [UIFont fontWithName:#"ArialMT" size:18.0f]
}];
CGFloat verticalOffset = -4;
[[UINavigationBar appearance] setTitleVerticalPositionAdjustment:verticalOffset forBarMetrics:UIBarMetricsDefault];
}
else
{
[[UINavigationBar appearance] setBarTintColor:[UIColor whiteColor]];
// Uncomment to change the color of back button
[[UINavigationBar appearance] setTintColor:[UIColor whiteColor]];
// Uncomment to assign a custom backgroung image
[[UINavigationBar appearance] setBackgroundImage:[UIImage imageNamed:#"nav_bg_ios7.png"] forBarMetrics:UIBarMetricsDefault];
// Uncomment to change the back indicator image
[[UINavigationBar appearance] setBackIndicatorImage:[UIImage imageNamed:#""]];
[[UINavigationBar appearance] setBackIndicatorTransitionMaskImage:[UIImage imageNamed:#""]];
// Uncomment to change the font style of the title
NSShadow *shadow = [[NSShadow alloc] init];
shadow.shadowColor = [UIColor colorWithRed:0.0 green:0.0 blue:0.0 alpha:0.8];
shadow.shadowOffset = CGSizeMake(0, 1);

In iOS 7 try:
[self.navigationController.navigationBar setTranslucent:NO];
I'm trying to change the background color of the MFMailComposeViewController in iOS7 but I cannot make it work.
I'm using the following snipped:
MFMailComposeViewController *picker = [[MFMailComposeViewController alloc] init];
picker.mailComposeDelegate = self;
if([picker.navigationBar respondsToSelector:#selector(barTintColor)]) {
// iOS7
picker.navigationBar.barTintColor = READER_NAVIGATION_BAR_BACKGROUND_COLOR;
// Set back button arrow color
[picker.navigationBar setTintColor:READER_NAVIGATION_BAR_BACK_BUTTON_ARROW_COLOR];
// Set Navigation Bar Title Color
[picker.navigationBar setTitleTextAttributes:[NSDictionary dictionaryWithObject:READER_NAVIGATION_BAR_TITLE_NORMAL_FONT_COLOR forKey:UITextAttributeTextColor]];
// Set back button color
[[UIBarButtonItem appearanceWhenContainedIn:[UINavigationBar class], nil] setTitleTextAttributes:[NSDictionary dictionaryWithObjectsAndKeys:READER_NAVIGATION_BAR_BUTTONS_FONT_COLOR, UITextAttributeTextColor,nil] forState:UIControlStateNormal];
}
Does anybody knows how to change the bakcground color of the MFMailComposeViewController in iOS7?
The trick here is to call 'appearance methods' such as
[UINavigationBar appearance].barTintColor = [UIColor whiteColor];
[UINavigationBar appearance].tintColor = [UIColor redColor];
BEFORE calling to
[[MFMailComposeViewController alloc] init];
This way the color scheme will be applied to the mail composer.
It may be returned back to defaults in mailComposeController:didFinishWithResult:
try this. worked for me.
MFMailComposeViewController* myailViewController = [[MFMailComposeViewController alloc] init];
// set other attributes of mailcomposer here.
myMailViewController.mailComposeDelegate = self;
[myMailViewController.navigationBar setTintColor:[UIColor whiteColor]];
[self presentViewController:myMmailViewController animated:YES completion:nil];
Swift 3 solution:
extension MFMailComposeViewController {
override open func viewDidAppear(_ animated: Bool) {
super.viewDidAppear(animated)
UIApplication.shared.statusBarStyle = UIStatusBarStyle.lightContent
}
open override func viewDidLoad() {
super.viewDidLoad()
navigationBar.isTranslucent = false
navigationBar.isOpaque = false
navigationBar.barTintColor = UIColor.white
navigationBar.tintColor = UIColor.white
}
}
For iOS8:
NSDictionary *navbarTitleTextAttributes = [NSDictionary dictionaryWithObjectsAndKeys:
[UIColor whiteColor],UITextAttributeTextColor,
[UIColor blackColor], UITextAttributeTextShadowColor,
[NSValue valueWithUIOffset:UIOffsetMake(-1, 0)], UITextAttributeTextShadowOffset, nil];
[[UINavigationBar appearance] setTitleTextAttributes:navbarTitleTextAttributes];
Or
navigationController.navigationBar.titleTextAttributes = [NSDictionary dictionaryWithObject:[UIColor yellowColor] forKey:UITextAttributeTextColor];
try this but one thing BarTintColor available only iOS7
[[UINavigationBar appearance] setBarTintColor:[UIColor redColor]];
This color is made translucent by default unless you set the translucent property to NO.
or try this link it will more helpful you
Changing MFMailComposeViewController's toolbar color
Try the following code
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
[[UINavigationBar appearance] setBarTintColor:[UIColor blackColor]];
[[UINavigationBar appearance] setBackgroundColor:[UIColor blackColor]];
// Your usual code follows here ......
#SoftDesigner's answer:
As of iOS 9:
[UINavigationBar appearance].tintColor = yourFavoriteColor;
does not work on the MFMailComposeViewController.
The rest of the answer works (I used it), but as far as I can tell you're stuck with Apple's colors for the nav bar buttons.
Hope this saves someone else some angst.
First present the MFMailComposeViewController then change its tintColor
[self presentViewController:emailDialog animated:TRUE completion:nil];
[[UINavigationBar appearance] setBackgroundImage:nil
forBarPosition:UIBarPositionTopAttached
barMetrics:UIBarMetricsDefault];
I had a problem that prevented me from setting the background colour. Turns out I had some other code elsewhere setting the background image to [UIImage new].
The following code fixed it:
[[UINavigationBar appearance] setBackgroundImage:nil forBarMetrics:UIBarMetricsDefault];
[[UINavigationBar appearance] setShadowImage:nil];
I am trying to change the look of the UINavigationBar in my iOS7 app. I am doing the following:
- (void)viewDidLoad
{
[super viewDidLoad];
m_sNumberToCall = #"";
UIBarButtonItem * btn = [[UIBarButtonItem alloc] initWithImage:[UIImage imageNamed:#"IconHome.png"] style:UIBarButtonItemStyleBordered target:self action:#selector(btHomeTouched:)];
self.navigationItem.leftBarButtonItem = btn;
self.navigationController.navigationBar.translucent = YES;
[[UINavigationBar appearance] setBackgroundImage:[UIImage imageNamed:#"TVCNavBack.png"] forBarMetrics:UIBarMetricsDefault];
NSShadow * shadow = [[NSShadow alloc] init];
shadow.shadowColor = [UIColor colorWithRed:0.0 green:0.0 blue:0.0 alpha:0.8];
shadow.shadowOffset = CGSizeMake(0, 1);
[[UINavigationBar appearance] setTitleTextAttributes: [NSDictionary dictionaryWithObjectsAndKeys:
[UIColor colorWithRed:245.0/255.0 green:245.0/255.0 blue:245.0/255.0 alpha:1.0],
NSForegroundColorAttributeName,
shadow,
NSShadowAttributeName,
[UIFont fontWithName:#"Helvetica-Bold" size:21.0],
NSFontAttributeName,
nil]];
}
But, the first time I present the UITableViewController it is the standard iOS7 nav bar, then I press home and present it again and it is my new look.
Any ideas why it does not work the first time?
Don't change the appearance but the navigation bar directly. The appearance affects only the future instances but not the already created ones.
Change:
[[UINavigationBar appearance] setBackgroundImage:[UIImage imageNamed:#"TVCNavBack.png"] forBarMetrics:UIBarMetricsDefault];
to:
[self.navigationController.navigationBar setBackgroundImage:[UIImage imageNamed:#"TVCNavBack.png"] forBarMetrics:UIBarMetricsDefault];
The answer before only helps you with the background image but not with the title text attributes.
You don't need to change your code but all you have to do is move it to
applicationDidFinishLaunchingWithOptions
in your AppDelegate.m file.
When i add background image to uinavigationbar it hides my title on uinavigationbar,
Here is my code,
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
...
...
[[UINavigationBar appearance] setBackgroundImage:[UIImage imageNamed: #"BarBg.png"] forBarMetrics:UIBarMetricsDefault];
}
Code in Class:
int height = self.navigationController.navigationBar.frame.size.height;
int width = self.navigationController.navigationBar.frame.size.width;
UILabel *navLabel = [[UILabel alloc] initWithFrame:CGRectMake(0, 0, width, height)];
navLabel.text=#"Categories";
navLabel.backgroundColor = [UIColor clearColor];
navLabel.textColor = [UIColor whiteColor];
navLabel.font = [UIFont boldSystemFontOfSize:17];
navLabel.textAlignment = NSTextAlignmentCenter;
self.navigationItem.titleView = navLabel;
After writing this code i am unable to see title on navigation bar, title is behind navigationBar image.
Please help, Thanks in advance..
instead of set label as a titleView of UINavigationBar add that UILabel as a Subview of NavigationBar like bellow...
[self.navigationController.navigationBar addSubview:navLabel];
[self.navigationController.navigationBar bringSubviewToFront:navLabel];
If you're looking only to customize your navigationBar title, I recommend using the appearance instead of adding a label to your navbar.
[[UINavigationBar appearance] setTitleTextAttributes:#{
UITextAttributeFont: [UIFont fontWithName:yourFontName size:fontSize],
UITextAttributeTextColor :[UIColor whiteColor],
}];
