UIBarButtonItem appearance iOS5 font - iphone

I am using a little chunk of code like below to change the text attributes of my nav bar title app wide and it works great.
[[UINavigationBar appearance] setTitleTextAttributes:
[NSDictionary dictionaryWithObjectsAndKeys:
[UIColor whiteColor], UITextAttributeTextColor,
[UIColor grayColor], UITextAttributeTextShadowColor,
[NSValue valueWithUIOffset:UIOffsetMake(0, -1)], UITextAttributeTextShadowOffset,
[UIFont fontWithName:#"Cochin-BoldItalic" size:0.0], UITextAttributeFont,
nil]];
But I want to be able to just as easily do this for UIBarButtonItem text as well but I can't figure it out as it doesn't share the same or similar methods it appears.
Edit
Tried this code, not making any changes to text:
[[UIBarItem appearance] setTitleTextAttributes:
[NSDictionary dictionaryWithObjectsAndKeys:
[UIColor whiteColor], UITextAttributeTextColor,
[UIColor grayColor], UITextAttributeTextShadowColor,
[NSValue valueWithUIOffset:UIOffsetMake(0, -1)], UITextAttributeTextShadowOffset,
[UIFont fontWithName:#"Cochin-BoldItalic" size:12.0], UITextAttributeFont,
nil]
forState:UIControlStateNormal];


You want to use the - (void)setTitleTextAttributes:(NSDictionary *)attributes forState:(UIControlState)state method of UIBarItem (UIBarButtonItem inherits from UIBarItem).
Check out the docs for more details: http://developer.apple.com/library/ios/#documentation/uikit/reference/UIBarItem_Class/Reference/Reference.html#//apple_ref/occ/cl/UIBarItem
Try this:
//Suppose you have initialized barButton elsewhere`
[barButton setTitleTextAttributes:
[NSDictionary dictionaryWithObjectsAndKeys:
[UIColor whiteColor], UITextAttributeTextColor,
[UIColor grayColor], UITextAttributeTextShadowColor,
[NSValue valueWithUIOffset:UIOffsetMake(0, -1)], UITextAttributeTextShadowOffset,
[UIFont fontWithName:#"Cochin-BoldItalic" size:12.0], UITextAttributeFont,
nil]
forState:UIControlStateNormal];


This seems to work on iOS 7.1:
[[UIBarButtonItem appearance] setTitleTextAttributes:#{NSForegroundColorAttributeName:[UIColor whiteColor],
NSFontAttributeName:[UIFont fontWithName:#"Resamitz" size:16.0]}
forState:UIControlStateNormal];

Backbarbuttonitem letterpress effect

How can I recreate the letterpress-like effect applied to the backbarbuttonitem in the notes app in ios 7? I tried the following:
NSShadow *textShadow = [[NSShadow alloc] init];
textShadow.shadowOffset = CGSizeMake(0.0, -1.0);
textShadow.shadowColor = [UIColor blackColor];
NSAttributedString *attributedTitle = [[NSAttributedString alloc] initWithString:#"Back" attributes:#{NSForegroundColorAttributeName : [UIColor orangeColor], NSShadowAttributeName : textShadow}];
self.navigationItem.backBarButtonItem = [[UIBarButtonItem alloc] initWithTitle:attributedTitle style:UIBarButtonItemStylePlain target:nil action:nil];
But it says I can't use NSAttributedString in place of an NSString.

For iOS 5 and above, you can use the UIAppearance functionality to change the Text Color, Font, Tint Color etc of multiple UI Components like UITabBar, UIBarButton, etc.
for UIBarButtonItem, check the below two options.
Option1: For ANY UIBarButtonItem:
NSDictionary *aButtonAttribute = [NSDictionary dictionaryWithObjectsAndKeys:
[UIColor darkGrayColor], UITextAttributeTextColor,
[UIColor whiteColor], UITextAttributeTextShadowColor,
[NSValue valueWithUIOffset:UIOffsetMake(0, 1)], UITextAttributeTextShadowOffset, nil];
[[UIBarButtonItem appearance] setTitleTextAttributes:aButtonAttribute forState:UIControlStateNormal];
Option 2: For UIBarButtonItem of a UINavigationBar ONLY:
NSDictionary *aButtonAttribute = [NSDictionary dictionaryWithObjectsAndKeys:
[UIColor darkGrayColor], UITextAttributeTextColor,
[UIColor whiteColor], UITextAttributeTextShadowColor,
[NSValue valueWithUIOffset:UIOffsetMake(0, 1)], UITextAttributeTextShadowOffset, nil];
[[UIBarButtonItem appearanceWhenContainedIn:[UINavigationBar class], nil] setTitleTextAttributes:aButtonAttribute forState: UIControlStateNormal];
NOTE: You can add these lines (either of the 2 options) in the .m file of AppDelegate..

How to customise UITabBar text label?

does anybody know how to use the Appearance proxy object
[[UITabBar appearance] set....];
to customise the color,font and shadow for the selected/unselected label of an UITabBar?
thanks a lot.

By accessing the tab-bar item object of the UITabBar for each UIViewController
This only works for iOS5.0 or later.
if ([self.tabBarItem respondsToSelector:#selector(setTitleTextAttributes:)]) {
NSLog(#"*** Support method(iOS 5): setTitleTextAttributes:");
[self.tabBarItem setTitleTextAttributes:[NSDictionary dictionaryWithObjectsAndKeys:
[UIFont fontWithName:#"AmericanTypewriter" size:20.0f], UITextAttributeFont,
[UIColor blackColor], UITextAttributeTextColor,
[UIColor grayColor], UITextAttributeTextShadowColor,
[NSValue valueWithUIOffset:UIOffsetMake(0.0f, 1.0f)], UITextAttributeTextShadowOffset,
nil]];
}

UITabBarItem appearance -setTitleTextAttributes keeps logging "state = 1 is interpreted as UIControlStateHighlighted"?

In my AppDelegate implementation file I use these lines of code to set custom fonts and colors of tabBarItems:
[[UITabBarItem appearance] setTitleTextAttributes:
[NSDictionary dictionaryWithObjectsAndKeys:
[UIColor grayColor], UITextAttributeTextColor,
[UIFont fontWithName:#"Arial" size:0.0], UITextAttributeFont,
nil] forState:UIControlStateNormal];
[[UITabBarItem appearance] setTitleTextAttributes:
[NSDictionary dictionaryWithObjectsAndKeys:
[UIColor whiteColor], UITextAttributeTextColor,
[UIFont fontWithName:#"Arial" size:0.0], UITextAttributeFont,
nil] forState:UIControlStateHighlighted];
For some (unknown) reason the following messages get logged, one for each tabBarItem:
button text attributes only respected for UIControlStateNormal, UIControlStateHighlighted and UIControlStateDisabled. state = 1 is interpreted as UIControlStateHighlighted.
Couldn't find anything using the standard search engines, so I seek your help. What am I doing wrong and how to fix this?
Thank you in advance for any suggestions.

Just change the "UIControlStateHighlighted" to "UIControlStateSelected". Hope this helps!

I had the same issue because I was using:
[[UIBarButtonItem appearance] setTitleTextAttributes:
[NSDictionary dictionaryWithObjectsAndKeys:
[UIColor whiteColor], UITextAttributeTextColor, nil] forState:UIControlStateSelected];
I changed it to:
[[UIBarButtonItem appearance] setTitleTextAttributes:
[NSDictionary dictionaryWithObjectsAndKeys:
[UIColor whiteColor], UITextAttributeTextColor, nil] forState:UIControlStateHighlighted];
…and the problem went away. Hope this helps!

Change UILabel Text inside UISegmentedControll according to its status

Is there any way to use UIAppearance to change the text color of a selected segment in UISegmented Controller and let other segments have same Color ?

NSDictionary *attributesDictionary = [NSDictionary dictionaryWithObjectsAndKeys:
[UIColor colorWithRed:220.0/255.0 green:104.0/255.0 blue:1.0/255.0 alpha:1.0], UITextAttributeTextColor,
[UIColor colorWithRed:1.0 green:1.0 blue:1.0 alpha:1.0], UITextAttributeTextShadowColor,
[NSValue valueWithUIOffset:UIOffsetMake(0, 1)], UITextAttributeTextShadowOffset,
[UIFont systemFontOfSize:14], UITextAttributeFont,
nil];
[[UISegmentedControl appearance] setTitleTextAttributes:attributesDictionary forState:UIControlStateSelected];

//iOS 4.whatever and below

}
[[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleBlackOpaque animated:NO];
}

UITabBar can either take an image and use its alpha channel (opacity) to build the selected/unselected images or take two processed images to use as is.
You'll have to provide the images yourself to the UITabBarItem with 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.
