I tried doing it like described in How to change Navigation Bar color in iOS 7? but unfortunatley it does not seem to work for me.
The color only changes to a light version. Since a screenshot describes it better than a thousand words here you go:
use this code work for me
[[UINavigationBar appearance]setBarTintColor:[UIColor colorWithRed:95/255.f green:154/255.f blue:201/255.f alpha:1]];
using storyboard
novice iOS developer and I am trying to figure out why my Navigation bar height wont change after I programmatically change it. I have done the following things:
I added this piece of code to the AppDelegate.m in the didFinishLaunchingWithOptions method
[[UINavigationBar appearance] setFrame:CGRectMake(0, 0, 320, 200)];
I was told that this would create a much larger navigation bar but it doesn't seem to be doing so.
I have also added the following code in a specific view controller (FirstViewController.m) to change the font family, text color, etc.
-(void)awakeFromNib {
[[UINavigationBar appearance] setBarTintColor:[UIColor colorWithRed:(72/255.0) green:(167/255.0) blue:(192/255.0) alpha:1]];
[self.navigationController.navigationBar setTitleTextAttributes:
[NSDictionary dictionaryWithObjectsAndKeys:
[UIFont fontWithName:#"CaviarDreams" size:28], NSFontAttributeName,
[UIColor whiteColor], NSForegroundColorAttributeName, nil]];}
Am I doing something wrong here?
Any help would be great!!
You can change the height of a navigation bar if it is your navigation bar - if it's just a free-standing interface object.
But if you're using a UINavigationController, the height of the navigation bar is really not up to you. The UINavigationController does the layout of views, and you can't really change what it does. That is part of the price of using this built-in structure, if you see what I mean.
As for your other attempts, you are probably doing them at the wrong time. For example, in awakeFromNib it makes no sense to talk about self.navigationController.navigationBar as it is probably nil anyway at that time (you can easily check with logging). That is why it is better to use the appearance proxy. But then you are doing that too late; you have to use the appearance proxy in application:didFinishLaunching...:, because it affects only future instances of that type.
Basically as a newbie you need to learn what Cocoa lets you do and what it doesn't, and when are the right moments in the process to do those things. It's a big framework. You're in bed with a gorilla; you need to know when the gorilla wants to turn over and let it turn over, or you'll just get squashed. You'll get better at this as you become more accustomed to it.
I am trying to customize the appearance of the navigationBar title in my ios application. This is the code I currently have:
NSMutableDictionary *navigationTitleAttributes = [NSMutableDictionary dictionary];
[navigationTitleAttributes setValue:[UIColor whiteColor] forKey:UITextAttributeTextColor];
[navigationTitleAttributes setValue:[UIColor clearColor] forKey:UITextAttributeTextShadowColor];
[navigationTitleAttributes setValue:[NSValue valueWithUIOffset:UIOffsetMake(0.0, 0.0)] forKey:UITextAttributeTextShadowOffset];
[navigationTitleAttributes setValue:[UIFont fontWithName:#"Calibri" size:30] forKey:UITextAttributeFont];
[[UINavigationBar appearance] setTitleTextAttributes:navigationTitleAttributes];
[[UINavigationBar appearance] setTitleVerticalPositionAdjustment:-8 forBarMetrics:UIBarMetricsDefault];
The code yields the following effect:
It works great but my title gets cut off from the bottom.
I've seen solutions to this problem that use a custom UIView (such as this one: UINavigationbar title is cut off when using titleTextAttributes). However, that particular solution requires that the titleView property of the navigation bar be updated for each screen.
I was wondering if there was a simple solution that would cascade through my entire application.
Thanks
Th simple solution is to not use such a large font size. If you set the size to zero then the text should be auto-sized as appropriate.
Otherwise, using a custom view is the correct solution. You can subclass the navigation controller or navigation bar in order to ensure that all of the views have the label styled in the same way.
If you're using a custom font, you may be having the same problem I was. I found a few answers on this post to be quite helpful. I changed my descender values in my .otf font file to prevent my font from being cut off on the bottom. It was especially prevalent in iOS 7.
Custom installed font not displayed correctly in UILabel
I am customizing the UITabBar. I used my custom image in UITabBarItem. The problem is whether there is a gradient/gloss on the item. I checked Apple's app Store didn't had any of this glossy effect on its UITabBarItem. How can i remove gradient from UITabBarItem?
You just need to put clear image as `yourImage', it may help you
[[UITabBar appearance] setSelectionIndicatorImage:[UIImage {yourImage}]]
Edit
i just googled it and found lot of similar questions. You can also try below code of lines
[[UITabBar appearance] setShadowImage:[UIImage imageNamed:#"Tappbarimage.png"]];
You'll have to provide the images yourself to the UITabBarItem with using this tabbarMethod setFinishedSelectedImage:withFinishedUnselectedImage:.
There's no other way to affect the processing it does to the images besides changing the color of the gradient with UITabBar's selectedImageTintColor appearance property.
I need to change the selection color of UITabBar from default blue to red. How do we do this.
Update September 2017:
It's been two years since I've written this answer and since it's receiving upvotes regularly, I should say this is probably the worst possible answer to this question, it's error prone, likely to break because of iOS updates, hard to debug, etc., so please don't do the things I've written and apply better solutions such as subclassing UITabBar or UITabBarController. Thanks.
You can do this by setting a "tintColor" attribute (Key Path) for you UITabBar.
Select the UITabBar in the document outline. (NOT the Controller with the yellow icon.)
Select Identity Inspector in the Utilities area.
Click the + in "User Defined Runtime Attributes."
Add a "tintColor" Key Path of type "Color" and the color you want.
This should do it. You can check it against the screenshot below.
More on this:
There's a "Tint" attribute in Identity Inspector of UITabBar which I believed would do the exact same thing but apparently, it does nothing. It's default value is the exact default fill color when a UITabBarItem is selected, so my guess is it would be fixed in the stable release Xcode 7. Fingers crossed.
In IOS5, UITabBar has a selectedImageTintColor property which does what you need.
In iOS 7 it's simply the tintColor. One way to accomplish this could be to subclass UITabBarViewController, set the custom class in the storyboard, and in your viewDidLoad method of the subclassed tabBarVC add this:
[[self tabBar] setTintColor:[UIColor redColor]];
To achieve above result perform following steps.
Step 1: Add your desired images in Assets.xcassets, and make sure they Render As: Default
Step 2: Select your UITabBar object and set Image Tint color, this color will be selected tab color
Step 3: Select UITabBar object and add Key Path: unselectedItemTintColor, Type: Color, Value: Choose color for unselected item in User Defined Runtime Attributes.
All done.
It is extremely easy
Create a custom class of UITabBarController and in -(void)viewDidLoad method add this line:
[[self tabBar] setSelectedImageTintColor:[UIColor greenColor]];
Because UITextAttributeTextColor is deprecated in iOS 7, you should use:
[UITabBarItem.appearance setTitleTextAttributes:#{NSForegroundColorAttributeName : [UIColor greenColor]} forState:UIControlStateNormal];
[UITabBarItem.appearance setTitleTextAttributes:#{NSForegroundColorAttributeName : [UIColor purpleColor]} forState:UIControlStateSelected];
Starting from iOS 8 it's as simple as:
UITabBar.appearance().tintColor = UIColor.redColor()
Simply change the following property in Interface Builder for the TabBar
Obviously in my case its White.
The SDK does not make this easy, but it is technically possible. Apple apparently believes this to be part of their vision of a consistent look and feel.
UITabBar is a subclass of UIView. You can always subclass and implement your own -drawRect:
This is not a trivial task, however, you have to essentially re-implement the class from scratch or you risk some weird side-effects.
Swift 5 Programatically
It is pretty easy in Swift 5.
In your TabBarController write this:
tintColor = UIColor.red
That's it
I've been searching for a way to set the selected text color of a UITabBarItem and have found a dead simple method, using the UIAppearance protocol.
[UITabBarItem.appearance setTitleTextAttributes:#{
UITextAttributeTextColor : [UIColor greenColor] } forState:UIControlStateNormal];
[UITabBarItem.appearance setTitleTextAttributes:#{
UITextAttributeTextColor : [UIColor purpleColor] } forState:UIControlStateSelected];
Please excuse the awful colors!
iOS 5.0 fixes this issue but the solution is under NDA. Look up UITabBar in your documentation for an EASY way to do what you want to do.
I found the easiest solution -
Select Tab Bar in Tab Bar Controller
Set Image Tint color
Set Tint Color
