I'd like to set different colors for a UITabBarItem's title text and image in the unselected state.
For the selected state, I can accomplish this like so:
[[UITabBar appearance] setTintColor:[UIColor purpleColor]]; // image color
[[UITabBarItem appearance] setTitleTextAttributes:#{ NSForegroundColorAttributeName: [UIColor orangeColor] } forState:UIControlStateSelected]; // text color
For the unselected state, I'm attempting the following:
[[UITabBar appearance] setUnselectedItemTintColor:[UIColor blueColor]]; // image color
[[UITabBarItem appearance] setTitleTextAttributes:#{ NSForegroundColorAttributeName: [UIColor redColor] } forState:UIControlStateNormal]; // text color
But for some reason, the unselectedItemTintColor setting overrides whatever I try and set for the titleTextAttributes – so in the snippet above, both the text and image would appear blue.
I've also tried changing the titleTextAttributes directly on the UITabBarItem after I've created it (instead of using appearance), but again this seems to have no effect.
How can I achieve different unselected colors? Is it possible?
I managed to solve this shortly after posting. It turns out that while setting the unselectedItemTintColor using UIAppearance overrides the titleTextAttributes for the item, everything works correctly if you set the unselectedItemTintColor directly on the tab bar itself.
So instead of
[[UITabBar appearance] setUnselectedItemTintColor:[UIColor blueColor]];
just do
[self.myTabBarInstance setUnselectedItemTintColor:[UIColor blueColor]];
I am trying to change the color of the navigation bars in my app with UIAppearance.
But only when I use a system color, it works:
UINavigationBar *navigationBarAppearance = [UINavigationBar appearance];
[navigationBarAppearance setBarTintColor:[[UIColor alloc] initWithRed:220.0f green:47.0f blue:40.0f alpha:100.0f]]; // does not work
[navigationBarAppearance setBarTintColor:[UIColor colorWithRed:220.0f green:47.0f blue:40.0f alpha:100.0f]]; // does not work
[navigationBarAppearance setBarTintColor:[UIColor redColor]]; // works
Any suggestions?
The method
colorWithRed:green:blue:alpha:
accept four value between 0.0 and 1.0. So if you have the components from 0.0 to 255.0 you need to normalize with a division by 255.0f.
[UIColor alloc] initWithRed:220.0f/255.0f green:47.0f/255.0f blue:40.0f/255.0f alpha:100.0f/255.0f]
I think you are doing wrong with custom color method, its like this
[[UINavigationBar appearance] setBarTintColor:[UIColor colorWithRed:127.0f/255.0f green:127.0f/255.0f blue:127.0f/255.0f alpha:1.0f]];
Hi I am trying to change the tint color of a newly created navigation bar but i am having difficulty getting the tint color to change and have tried various ways of implementing tintColor. Here is how I am creating it.
UINavigationBar *navBar = [[UINavigationBar alloc]initWithFrame:CGRectMake(0, 0, 320, 64)];
[navBar setTintColor:[UIColor redColor]];
[settingsView addSubview:navBar];
Do I need to approach it differently or redraw it?
Can you try this,
[navBar setBarStyle:UIBarStyleBlackOpaque];
[navBar setTintColor:[UIColor redColor]];
iOS 7 Has a method called setBarTintColor which works perfectly
Worked perfectly for me!
[self.homeNavigationBar setBarTintColor:[UIColor whiteColor]];
Try this:
[[UINavigationBar appearance] setBarTintColor:[UIcolor redcolor]];
use this code
UIColor *appcolor=[UIColor colorWithRed:63.0/255.0 green:148.0/255.0 blue:246.0/255.0 alpha:1.0];
[[UINavigationBar appearance] setBarTintColor:[UIColor appcolor]];
IOS 7 UISegmentControl set tint color not working.
How am I going to solve it?
Here is my code for adding:
UISegmentedControl *segmentControl = [[UISegmentedControl alloc] initWithItems:[NSMutableArray arrayWithObjects:#"YES",#"NO", nil]];
[segmentControl setTintColor:[UIColor orangeColor]];
but the color only appear at border, i want it to color whole background.
As I referred from the Library,
#property(nonatomic) UISegmentedControlStyle segmentedControlStyle NS_DEPRECATED_IOS(2_0, 7_0, "The segmentedControlStyle property no longer has any effect");*
The UISegmentedControl relates to the tint color of the UINavigationBar.
If you change the color, the tint color of the UISegmentedControl will change accordingly.
[[UINavigationBar appearance] setTintColor:[UIColor blackColor]];
I think you may want:
[segmentControl setBackgroundColor:[UIColor orangeColor]];
I want to change the color of the navigation bar color, but I'm not sure whether or not I should change the tint or the background. I know iOS 7 is going for a more flat design (even recommending removing gradients), but I am having trouble deciphering the two. Even if I set a background color, it doesn't do anything.
In this image, the background is set to green, but the bar is still blue:
The behavior of tintColor for bars has changed on iOS 7.0. It no longer affects the bar's background and behaves as described for the tintColor property added to UIView.
To tint the bar's background, please use -barTintColor.
navController.navigationBar.barTintColor = [UIColor navigationColor];
If you want to have a solid color for your navigation bar in iOS 6 similar to iOS 7 use this:
[[UINavigationBar appearance] setBackgroundImage:[[UIImage alloc] init] forBarMetrics:UIBarMetricsDefault];
[[UINavigationBar appearance] setBackgroundColor:[UIColor greenColor]];
in iOS 7 use the barTintColor like this:
navigationController.navigationBar.barTintColor = [UIColor greenColor];
or
[[UINavigationBar appearance] setBarTintColor:[UIColor greenColor]];
// In ios 7 :-
[self.navigationController.navigationBar setBarTintColor:[UIColor yellowColor]];
// In ios 6 :-
[self.navigationController.navigationBar setTintColor:[UIColor yellowColor]];
The background color property is ignored on a UINavigationBar, so if you want to adjust the look and feel you either have to use the tintColor or call some of the other methods listed under "Customizing the Bar Appearance" of the UINavigationBar class reference (like setBackgroundImage:forBarMetrics:).
Be aware that the tintColor property works differently in iOS 7, so if you want a consistent look between iOS 7 and prior version using a background image might be your best bet. It's also worth mentioning that you can't configure the background image in the Storyboard, you'll have to create an IBOutlet to your UINavigationBar and change it in viewDidLoad or some other appropriate place.
One more thing, if you want to change the navigation bg color in UIPopover you need to set barStyle to UIBarStyleBlack
if([UINavigationBar instancesRespondToSelector:#selector(barTintColor)]){ //iOS7
navigationController.navigationBar.barStyle = UIBarStyleBlack;
navigationController.navigationBar.barTintColor = [UIColor redColor];
}
Here is how to set it correctly for both iOS 6 and 7.
+ (void)fixNavBarColor:(UINavigationBar*)bar {
if (iosVersion >= 7) {
bar.barTintColor = [UIColor redColor];
bar.translucent = NO;
}else {
bar.tintColor = [UIColor redColor];
bar.opaque = YES;
}
}
The complete code with version checking.
if (NSFoundationVersionNumber > NSFoundationVersionNumber_iOS_6_1) {
// do stuff for iOS 7 and newer
[self.navigationController.navigationBar setBarTintColor:[UIColor yellowColor]];
}
else {
// do stuff for older versions than iOS 7
[self.navigationController.navigationBar setTintColor:[UIColor yellowColor]];
}
You can check iOS Version and simply set the tint color of Navigation bar.
if (SYSTEM_VERSION_LESS_THAN(#"7.0")) {
self.navigationController.navigationBar.tintColor = [UIColor colorWithRed:0.9529 green:0.4392 blue:0.3333 alpha:1.0];
}else{
self.navigationController.navigationBar.barTintColor = [UIColor colorWithRed:0.9529 green:0.4392 blue:0.3333 alpha:1.0];
self.navigationItem.leftBarButtonItem.tintColor = [UIColor whiteColor];
[[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleLightContent];
}
Based on posted answered, this worked for me:
/* check for iOS 6 or 7 */
if ([[self navigationController].navigationBar respondsToSelector:#selector(setBarTintColor:)]) {
[[self navigationController].navigationBar setBarTintColor:[UIColor whiteColor]];
} else {
/* Set background and foreground */
[[self navigationController].navigationBar setTintColor:[UIColor whiteColor]];
[self navigationController].navigationBar.titleTextAttributes = [[NSDictionary alloc] initWithObjectsAndKeys:[UIColor blackColor],UITextAttributeTextColor,nil];
}
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]];
Insert the below code in didFinishLaunchingWithOptions() in AppDelegate.m
[[UINavigationBar appearance] setBarTintColor:[UIColor
colorWithRed:26.0/255.0 green:184.0/255.0 blue:110.0/255.0 alpha:1.0]];
I'm using following code (in C#) to change the color of the NavigationBar:
NavigationController.NavigationBar.SetBackgroundImage (new UIImage (), UIBarMetrics.Default);
NavigationController.NavigationBar.SetBackgroundImage (new UIImage (), UIBarMetrics.LandscapePhone);
NavigationController.NavigationBar.BackgroundColor = UIColor.Green;
The trick is that you need to get rid of the default background image and then the color will appear.
If you want to change a color of a navigation bar, use barTintColor property of it. In addition, if you set any color to tintColor of it, that affects to the navigation bar's item like a button.
FYI, you want to keep iOS 6 style bar, make a background image looks like previous style and set it.
For more detail, you can get more information from the following link:
https://developer.apple.com/library/ios/documentation/userexperience/conceptual/TransitionGuide/AppearanceCustomization.html
In iOS7, if your navigation controller is contained in tab bar, splitview or some other container, then for globally changing navigationbar appearance use following method ::
[[UINavigationBar appearanceWhenContainedIn:[UITabBarController class],nil] setBarTintColor:[UIColor blueColor]];
Try the code below in the - (void)viewDidLoad of your ViewController.m
[[[self navigationController] navigationBar] setTintColor:[UIColor yellowColor]];
this did work for me in iOS 6.. Try it..
I'm not sure about changing the tint vs the background color but this is how you change the tint color of the Navigation Bar:
Try this code..
[navigationController.navigationBar setTintColor:[UIColor redColor]; //Red as an example.
