I know how to change navigation bat tint colour in iOS 6:
[UINavigationBar appearance].tintColor = [UIColor colorWithRed:129/255.0 green:200/255.0 blue:244/255.0 alpha:1.0];
I'm adding this code in APPDelegate page.
Now I want to do this in iOS 7 but above code is not working.
I searched on net. I got a solution. By adding below function to every page I can change navigation color.
self.navigationController.navigationBar.barTintColor = [UIColor colorWithRed:129/255.0 green:200/255.0 blue:244/255.0 alpha:1.0];
But I need a function which can add to APPDelegate function.
Please help me to overcome this issue.
Why not to use setBarTintColor for appearance proxy, you can do this:
if (floor(NSFoundationVersionNumber) <= NSFoundationVersionNumber_iOS_6_1)
{
[[UINavigationBar appearance] setTintColor: [UIColor colorWithRed:129/255.0 green:200/255.0 blue:244/255.0 alpha:1.0]];
}
else
{
[[UINavigationBar appearance] setBarTintColor: [UIColor colorWithRed:129/255.0 green:200/255.0 blue:244/255.0 alpha:1.0]];
}
you can add bellow code in appdelegate.m
if your app is navigation based
// for background color
[nav.navigationBar setBarTintColor:[UIColor blueColor]];
// for change navigation title and button color
[[UINavigationBar appearance] setTitleTextAttributes:[NSDictionary dictionaryWithObjectsAndKeys:[UIColor whiteColor], NSForegroundColorAttributeName, [UIFont fontWithName:#"FontNAme" size:20], NSFontAttributeName, nil]];
[[UINavigationBar appearance] setTintColor:[UIColor whiteColor]];
Using respondsToSelector for version checking may be better.
if ([self.navigationBar respondsToSelector:#selector(setBarTintColor:)]) {
[self.navigationBar setBarTintColor: [UIColor colorWithRed:129/255.0 green:200/255.0 blue:244/255.0 alpha:1.0]];
} else {
[self.navigationBar setTintColor: [UIColor colorWithRed:129/255.0 green:200/255.0 blue:244/255.0 alpha:1.0]];
}
In Swift, for me, I wanted to change tint color for the Cancel and Send buttons, when the e-mail pops up. And it worked great.
(UIBarButtonItem.appearanceWhenContainedInInstancesOfClasses([UINavigationBar.self])).tintColor = UIColor.whiteColor()
Try [self.navigationController.navigationBar setTranslucent:NO];

In our app we're setting the navigationbar and toolbar color with the following code. With iOS 8.x this is working fine. Recently I have tested the app with iOS 7.x and the colors aren't shown. The bars are transparent and the text has white color (so this worked...)
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
// Override point for customization after application launch.
[[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleLightContent];
[[UINavigationBar appearance] setBarTintColor:[UIColor colorWithRed:255.0/255.0 green:167.0/255.0 blue:0.0/255.0 alpha:1.0]];
[[UINavigationBar appearance] setTintColor:[UIColor whiteColor]];
[[UIToolbar appearance] setBarTintColor:[UIColor colorWithRed:255.0/255.0 green:167.0/255.0 blue:0.0/255.0 alpha:1.0]];
[[UIToolbar appearance] setTintColor:[UIColor whiteColor]];
[[UINavigationBar appearance] setTitleTextAttributes:
[NSDictionary dictionaryWithObjectsAndKeys:
[UIColor whiteColor], NSForegroundColorAttributeName,
[UIColor clearColor], UITextAttributeTextShadowColor,
[NSValue valueWithUIOffset:UIOffsetMake(0, -1)], UITextAttributeTextShadowOffset,
[UIFont boldSystemFontOfSize:19.0], NSFontAttributeName,
nil]];
I hope somebody could explain me how to solve this. Setting the bars background color is no solution to me because i would use transparency.
The solution to this issue is to set the color-values manually in the popping-up ViewController again for iOS 7.
self.navigationController.toolbar.barStyle = UIBarStyleBlackTranslucent;
[self.navigationController.toolbar setTintColor:[UIColor whiteColor]];
[self.navigationController.toolbar setBarTintColor:[UIColor colorWithRed:255.0/255.0 green:167.0/255.0 blue:0.0/255.0 alpha:1.0]];
self.navigationController.navigationBar.barStyle = UIBarStyleBlackTranslucent;
[self.navigationController.navigationBar setTintColor:[UIColor whiteColor]];
[self.navigationController.navigationBar setBarTintColor:[UIColor colorWithRed:255.0/255.0 green:167.0/255.0 blue:0.0/255.0 alpha:1.0]];
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.

I have succesfully change the navbar button with this:
[[UINavigationBar appearance] setBarTintColor:[UIColor colorWithRed:26.0/255 green:132.0/255 blue:182.0/255 alpha:.5]];
What about if I want to change the color of the title (from black) or the color of the button?
This is what I have in my App Delegate in a method specially for changing appearances.
// set button tint colour to white
[[UINavigationBar appearance] setTintColor:[UIColor whiteColor]];
// set the bar tint colour to purplish
[[UINavigationBar appearance] setBarTintColor:[UIColor colorWithRed:.2 green:.458823529 blue:.592156863 alpha:1.0]];
// set title text label colour to white
[[UINavigationBar appearance] setTitleTextAttributes:#{NSForegroundColorAttributeName : [UIColor whiteColor]}];
For navigation bar title color in iOS7 you should use the setTitleTextAttributes of UINavigationBar appearance
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]];

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];
}

[[UINavigationBar appearance] setBarTintColor:[UIColor whiteColor]];
// Uncomment to change the color of back button
[[UINavigationBar appearance] setTintColor:[UIColor whiteColor]];

// Uncomment to change the back indicator image

[[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);
[[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:#"ArialMT" size:18.0], NSFontAttributeName, nil]];
CGFloat verticalOffset = -4;
[[UINavigationBar appearance] setTitleVerticalPositionAdjustment:verticalOffset forBarMetrics:UIBarMetricsDefault];
}
In iOS 7 try:
[self.navigationController.navigationBar setTranslucent:NO];
I have created a tabbar programmatically.
Can we change color of title of the tabbar item?
Default is white, and i m trying to make it black.
something like
tabbaritem.text.textcolor=[UIcolor Blackcolor];
Thanks
In iOS5 you use the appearance proxy to change the title color:
For a specific tabbar item:
[[UITabBarItem appearance] setTitleTextAttributes:[NSDictionary dictionaryWithObjectsAndKeys:
[UIFont fontWithName:#"AmericanTypewriter" size:20.0f], UITextAttributeFont,
[UIColor yellowColor], UITextAttributeTextColor,
[UIColor redColor], UITextAttributeTextShadowColor,
[NSValue valueWithUIOffset:UIOffsetMake(0.0f, 1.0f)], UITextAttributeTextShadowOffset,
nil] forState:UIControlStateNormal];
Or replace self.tabBarItem with [UITabBarItem appearance] to change all your tabbar items.
If you want to change them all , I suggest you place the code on appdelegate didFinishLaunchingWithOptions:
Just something else ...
To set your standard appearance in iOS 5:
In your AppDelegate.m do:
[[UITabBar appearance] setTintColor:myColor]; //or whatever you want to change
Saves you a lot of work.
Maybe this updated code helps someone:
[UITabBarItem.appearance setTitleTextAttributes:#{
NSForegroundColorAttributeName : [UIColor lightGrayColor] } forState:UIControlStateNormal];
[UITabBarItem.appearance setTitleTextAttributes:#{
NSForegroundColorAttributeName : [UIColor whiteColor] } forState:UIControlStateSelected];
