I have a UISearchBar with a dark background color so I was trying to change the place holder text color of UISearchBar (which will be gray by default) but I didn't find a way to set it. So I thought of getting some help :) please suggest me how this can be achieved thanks in advance :)
Note: At the time I wrote this answer I was working on iOS 7 & this workaround worked on iOS 8 as well. It may not work on iOS 9.
Ok it's been two days since I posted this question. Though I din't get the answer I got a workaround for this problem.
Note : I am using storyboard for my application & I have subclassed the UISearchBar and this workaround working like a gem for me.
First and foremost add an appearance proxy to UILabel when its contained in the UISearch bar class like this :
[[UILabel appearanceWhenContainedIn:[UISearchBar class], nil] setTextColor:[UIColor whiteColor]];//change the color to whichever color needed
Then the most important thing is If you're using storyboard you must and should write some text in the placeholder field of the attribute inspector like this
If you forget to write something in the placeholder field, definitely this trick will not work when you run the application and the placeholder text will look in usual gray color.
Once you're done with writing some text in placeholder field, set the place holder text in your UISearchBar sub class like this :
self.placeholder = #"My Placeholder text";
Now run the application !!! You'll get the place holder text in the color which you have set in appdelegate:) Hope this helps someone :)
Here is the solution
[searchBar setValue:[UIColor blueColor] forKeyPath:#"_searchField.textColor"];
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 trying to use UIAppearance to get a uniform color theme in my iOS app. For example I try to set the text color of all UILabel objects as follows:
[[UILabel appearance] setTextColor:[UIColor colorWithRed:0.7 green:0.07 blue:0.12 alpha:1]];
This works fine for all objects statically defined in my storyboard/XIBs. However, sometimes I need to dynamically create a UILabel in a view. In these cases, the UIAppearance is not used. Instead the default text color (black) is used instead.
Has anyone run into this issue/ found a way around it other than resorting to the old "set every element manually" approach?
Seems that not all the classes support UIAppearance and UILabel is not one of those.
Check this question for more info:
UIAppearance not taking effect on UILabels created programatically
Here's a list of classes that support UIAppearance:

I'm loving being able to use an appearance proxy in my iOS5 app to customise the NavigationController UI elements system-wide, however:
I have a lot of nested tables in my app, of which I'd love to be able to change the font across all table cells. They are mainly statically created. I've put some cell generation inside of a class, being read from an array, but the main issue lies with a large contents section I've tabled in Interface Builder. IB doesn't seem to have the option for mass-font setting.
I was wondering if anyone could help me find a way to set all the UITableCell fonts in one go?
Perhaps something like:
[[UILabel appearance] setFont:[UIFont fontWithName:#"Times" size:17.00];
You can use appearanceWhenContainedIn: to narrow down which UIViews you'd like to set the appearance for.
In your example, try:
[[UILabel appearanceWhenContainedIn:[UITableViewCell class], nil]
setFont:[UIFont fontWithName:#"Times" size:17.00]];
Actually, no. It is not valid to use UIAppearance to style a UILabel. See my self-answered question here. It kinda works, but it's not valid, for the reasons outlined over there.
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
