I am new to iOS development, I facing a strange problem. In viewDidLoad
I had written a code like this
self.navigationController.navigationBar.backgroundColor= [UIColor colorWithRed:189.0/255.0 green:105.0/255 blue:105.0/255 alpha:1.0];
this is working fine and changed the navigation bar background color, the problem is in the top of the navigation bar there is white bar showing (that has Carrier, Battery, time), I want that background color also changed... so I tried the below code
[[UINavigationBar appearance] setBackgroundColor:[UIColor colorWithRed:189.0/255.0 green:105.0/255 blue:105.0/255 alpha:1.0]];
But nothing changed, it is showing same white background color, I would like to know whats the mistake I am doing
Try this,
[[UINavigationBar appearance] setBarTintColor:[UIColor yellowColor]];
or
self.navigationController.navigationBar.barTintColor = [UIColor blueColor];
self.navigationController.navigationBar.tintColor = [UIColor whiteColor];
self.navigationController.navigationBar.translucent = NO;
and
[self.navigationController.navigationBar setBarStyle:UIStatusBarStyleLightContent];
You should use the barTintColor property in order to change the navigation bar background color and also the status bar background color.
[[UINavigationBar appearance] setBarTintColor:[UIColor colorWithRed:189.0/255.0 green:105.0/255 blue:105.0/255 alpha:1.0]];
My app has:
[[UIView appearance] setTintColor:[UIColor whiteColor]];
And here is what I have when on:
and off:
I need to make UISwitch border visible like in Settings.app:
Your [[UIView appearance] setTintColor:[UIColor whiteColor]]; is interfering with the tint color of your switch. The command to set the tint color is self.mySwitch.tintColor = [UIColor grayColor]; which sets the color used to tint the outline of the switch when it is turned off.
Will you please try adding this line to your AppDelegate's didFinishLaunchingWithOptions
[[UISwitch appearance] setTintColor:[UIColor grayColor]];
This should apply the chosen Tint color on all your UISwitch controls.
Rather than using the appearance proxies you can also use:
[self.mySwitch setThumbTintColor:[UIColor blueColor]];
[self.mySwitch setOnTintColor:[UIColor redColor]];
ie. Use setOnTintColor for the background/border color.
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.
Is there any way I can set the background of the Navigation Bar of the UINavigationController to a solid color?
I know I can change the Tint color, but that still leaves me with the gradient/glass effect.
Any way I can get rid of that, and just have a plain old solid color?
The following code also results in solid color of navigation bar:
[[UINavigationBar appearance] setBackgroundImage:[[UIImage alloc] init] forBarMetrics:UIBarMetricsDefault];
[[UINavigationBar appearance] setBackgroundColor:[UIColor redColor]];
I think you have to subclass UINavigationBar and override -(void)drawRect:(CGRect)rect:
UIColor *colorFlat = /* any UIColor*/
CGContextRef context = UIGraphicsGetCurrentContext();
CGContextSetFillColorWithColor(context, [colorFlat CGColor]);
CGContextFillRect(context, rect);
I used to override drawRect method and fill color; but after iOS7 upgrade it causes some problems on UINavigationBar. If you write your own drawrect method, even if you call [super drawRect], it changes the bar's dimension and you end up with a navigationBar with 44 pixels height. The status bar is left empty.
To get a solid colored navigationBar, I used an image as background image (any small solid colored image will do since you are stretching it) and added this lines inside the initWithFrame method of the UINavigationBar subclass:
[self setBackgroundColor:[UIColor clearColor]]
[[UINavigationBar appearance] setBackgroundImage:[[UIImage imageNamed:#"bgimage.png"] resizableImageWithCapInsets:UIEdgeInsetsMake(5, 5, 5, 5) resizingMode:UIImageResizingModeStretch] forBarMetrics:UIBarMetricsDefault];
The following code worked for me:
[self.navigationController.navigationBar setBackgroundImage:[UIImage new] forBarMetrics:UIBarMetricsDefault];
[self.navigationController.navigationBar setBarTintColor:[UIColor greenColor]];
self.navigationController.navigationBar.translucent = NO;
[self.navigationController.navigationBar setShadowImage:[UIImage new]];
Create a CustomUIViewController that extends UIViewController and override viewDidLoad to something like this:
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view from its nib.
self.view.backgroundColor = [UIColor colorWithRed: 0.0 green: 0.0 blue: 1.0 alpha: 1.0];
}
After that, use your CustomUIViewController in your controllers.
