I was wondering if someone would be able to help me with a problem I am having at the moment. I a m trying to change the actual font of the UITabBar, I have been able to chance the text colour and the colour when the text is selected. The code i have so far is here:
//Setting tab bar background
UIImage* tabBarBackground = [UIImage imageNamed:#"tabbar.png"];
[[UITabBar appearance] setBackgroundImage:tabBarBackground];
//[[UITabBar appearance] setSelectionIndicatorImage:[UIImage imageNamed:#"selected.png"]];
// Changes Selected Image color
[[UITabBar appearance] setTintColor:[UIColor colorWithRed:33.0/255.0 green:35.0/255.0 blue:38.0/255.0 alpha:1.0]]; //Icon colour
// Changes StateNormal text Color,
[UITabBarItem.appearance setTitleTextAttributes: #{NSForegroundColorAttributeName : [UIColor colorWithRed:214.0/255 green:69.0/255 blue:65.0/255 alpha:1.0]} forState:UIControlStateNormal]; //Colour of text when not seleted
// Changes StateSelected
UIColor *titleHighlightedColor = [UIColor colorWithRed:255.0/255.0 green:255.0/255.0 blue:255.0/255.0 alpha:1.0]; //Colour of text when selected
[UITabBarItem.appearance setTitleTextAttributes: #{NSForegroundColorAttributeName : titleHighlightedColor} forState:UIControlStateSelected];
I was wondering if anyone would know if it is possible to change the font here and if so how i would come across doing so? The code is located in the AppDelegate.m
Thanks in advance,
Harrison
Try adding it to the title text attributes:
[UITabBarItem.appearance setTitleTextAttributes: #{
NSForegroundColorAttributeName : [UIColor colorWithRed:214.0/255 green:69.0/255 blue:65.0/255 alpha:1.0],
NSFontAttributeName : [UIFont systemFontOfSize:20]
} forState:UIControlStateNormal];
You could use
[[UITabBarItem appearance] setTitleTextAttributes:[NSDictionary dictionaryWithObjectsAndKeys:[UIFont fontWithName:#"Arial" size:5.0f], NSFontAttributeName, nil] forState:UIControlStateNormal];

I am new to Objective C, need to change only the text color of a UISegmentedControl to white color, with the tint color is black opacity reduced. However this works on iPhone but on iPad the text color is not coming properly. It takes the tint color for its font also.
Below is the code i have used.
[ segCtrl setTintColor:[ UIColor colorWithRed:0.0/255.0 green:0.0/255.0 blue:0.0/255.0 alpha:0.15 ] ];
[ segCtrl setSelectedSegmentIndex:0 ];
[ segCtrl setTitleTextAttributes:#{NSFontAttributeName:[ UIFont fontWithName:FONTNAME size:13.0 ], NSForegroundColorAttributeName:[UIColor whiteColor ]} forState:UIControlStateNormal ];
How can i fix this. And why the same code differs in both devices.
Below are the images I get from iPhone and iPad
Put below code in viewdidload :
[[UISegmentedControl appearance] setTitleTextAttributes:#{NSForegroundColorAttributeName : [UIColor whiteColor]} forState:UIControlStateNormal];
[[UISegmentedControl appearance] setTitleTextAttributes:#{NSForegroundColorAttributeName : [UIColor whiteColor]} forState:UIControlStateSelected];
Worked for me.
use this code:
UISegmentedControl_Class
into viewDidLoad function.
// color selected text ---> red
[[UISegmentedControl appearance] setTitleTextAttributes:#{ NSForegroundColorAttributeName : [UIColor redColor] } forState:UIControlStateSelected];
// color disabled text ---> blue
[[UISegmentedControl appearance] setTitleTextAttributes:#{ NSForegroundColorAttributeName : [UIColor blueColor] } forState:UIControlStateNormal];
// color tint segmented control ---> Your color
[[UISegmentedControl appearance] setTintColor:[ UIColor colorWithRed:0.0/255.0 green:0.0/255.0 blue:0.0/255.0 alpha:0.15 ]];
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]];

I use the UIAppearance to change attributes of my title in Navigation Bar like so:
[[UINavigationBar appearance] setTitleTextAttributes:#{NSForegroundColorAttributeName : [MM mainTitleColor]}];
But I have not found the way to make text underlined or italic, is there a way to do this without changing the font alltogether?
No. These properties you cant change unless font changing. Because the available keys under the appearance proxy are
UITextAttributeFont
UITextAttributeTextColor
UITextAttributeTextShadowColor
UITextAttributeTextShadowOffset
Change these properties to customize the UINavigationBar
If you looking for font change, then see the below example
[[UINavigationBar appearance] setTitleTextAttributes:#{
UITextAttributeTextColor: TEXT_COLOR,
UITextAttributeTextShadowColor: SHADOW_COLOR,
UITextAttributeTextShadowOffset: [NSValue valueWithUIOffset:UIOffsetMake(0, -1)],
UITextAttributeFont: [UIFont fontWithName:#"Arial-Bold" size:0.0],
}];
Try this one.
You have to customise your navigation controller with adding a imageview.
UIFont *yourFont = [UIFont fontWithName:#"Helvetica-BoldOblique" size:[UIFont systemFontSize]];
if ([[UINavigationBar class]respondsToSelector:#selector(appearance)]) {
[[UINavigationBar appearance] setBackgroundImage:[UIImage imageNamed:#"myimage.png"] forBarMetrics:UIBarMetricsDefault];
}
[[UINavigationBar appearance] setTitleTextAttributes:#{
UITextAttributeTextColor : [UIColor clearColor],
UITextAttributeTextShadowColor : [UIColor blackColor],
UITextAttributeTextShadowOffset : [NSValue valueWithUIOffset:UIOffsetMake(1, 0)],
UITextAttributeFont : yourFont
}];
You can use :
Optima-BoldItalic
TimesNewRomanPS-BoldItalicMT
Baskerville-BoldItalic
HelveticaNeue-BoldItalic
TrebuchetMS-Bold
Helvetica-BoldOblique
You can try below code to make your text italic and bold.
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-BoldItalic" size:21.0], NSFontAttributeName, nil]];
[self setTitle:#"Title text"];
UPDATE ANSWERED. BY ME.
Currently having problems with the text color change of my UISegmentedControl; it needs to change on first load with UIControlStateSelected. Code works, but only conditionally. It works when you visit the page with the segmented control on the navigation bar, hit the back button, and then visit the page again. I'm assuming there's a problem with inheritance here. Let me explain..
The location of the the segmented control lies on top of my navigation bar.
Inheritance of the ViewController which contains the SegmentedControl:
TabBarViewController(managed with AppDelegate)-->navigation Controller-->ViewController(where 'inviteSegBar' lies)
Here's the code within AppDelegate.m:
[[UINavigationBar appearance] setBarTintColor:[UIColor colorWithHexString:#"#669900"]];//this one sets it green.
[[UINavigationBar appearance] setBackgroundColor:[UIColor whiteColor]];
And here's the viewDidLoad: code for the VC which contains 'inviteSegBar', the UISegmentedControl in question:
- (void)viewDidLoad
{
[super viewDidLoad];
//CUSTOM APPEARANCE <below>
self.navigationController.navigationBar.barTintColor = [UIColor whiteColor];
self.navigationController.navigationBar.tintColor = [UIColor colorWithHexString:#"#669900"];
inviteSegBar.tintColor = [UIColor colorWithHexString:#"#333333"];
[[UISegmentedControl appearance] setTitleTextAttributes:#{NSForegroundColorAttributeName : [UIColor colorWithHexString:#"#669900"]} forState:UIControlStateSelected];
}
Like I said the last line works, but only when you re-visit the page. Why is this happening?
PS This is the same issue guys, I had already tried this code before any of the answers were listed.
ANSWER FOUND: Simply move
[[UISegmentedControl appearance] setTitleTextAttributes:#{NSForegroundColorAttributeName : [UIColor colorWithHexString:#"#669900"]} forState:UIControlStateSelected];
to your AppDelegate.m file
Use
UIColor *whitecolor = [UIColor whiteColor];
NSDictionary *attributes = [NSDictionary dictionaryWithObjects:#[whitecolor] forKeys:#[UITextAttributeTextColor]];
[yourSegment setTitleTextAttributes:attributes
forState:UIControlStateNormal];
UIColor *grayColor = [UIColor darkGrayColor];
NSDictionary *attributes = [NSDictionary dictionaryWithObjects:#[grayColor] forKeys:#[UITextAttributeTextColor]];
[yourSegment setTitleTextAttributes:attributes
forState:UIControlStateSelected];
update
UIColor *whitecolor = [UIColor whiteColor];
NSDictionary *attributes = [NSDictionary dictionaryWithObjects:#[whitecolor] forKeys:#[NSForegroundColorAttributeName]];
[yourSegment setTitleTextAttributes:attributes
forState:UIControlStateNormal];
UIColor *grayColor = [UIColor darkGrayColor];
NSDictionary *attributes = [NSDictionary dictionaryWithObjects:#[grayColor] forKeys:#[NSForegroundColorAttributeName]];
[yourSegment setTitleTextAttributes:attributes
forState:UIControlStateSelected];
This code allows you to set some text attributes for label in segmented control:
NSDictionary *attributes = [NSDictionary dictionaryWithObjectsAndKeys:
[UIColor blackColor], UITextAttributeTextColor,
nil];
[_segmentedControl setTitleTextAttributes:attributes forState:UIControlStateSelected];
More allowed attributes in Apple documentation: link
This may help you:
UIAppearance proxy to set title text attributes but preserve tintColor for borders.
[[UISegmentedControl appearance] setTitleTextAttributes:#{
NSForegroundColorAttributeName : [UIColor redColor]
} forState:UIControlStateNormal];
For change UISegmentedControl appearance insert for example into viewDidLoad function this code:
// color selected text ---> red
[[UISegmentedControl appearance] setTitleTextAttributes:#{ NSForegroundColorAttributeName : [UIColor redColor] } forState:UIControlStateSelected];
// color disabled text ---> blue
[[UISegmentedControl appearance] setTitleTextAttributes:#{ NSForegroundColorAttributeName : [UIColor blueColor] } forState:UIControlStateNormal];
// color tint segmented control ---> black
[[UISegmentedControl appearance] setTintColor:[UIColor greenColor]];
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];
