[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]];

If you see this error: 'UITextAttributeTextShadowOffset' is deprecated: first deprecated in iOS 7.0 - Use NSShadowAttributeName with an NSShadow instance as the value.,try this.
如果您看到此错误：'UITextAttributeTextShadowOffset' is deprecated: first deprecated in iOS 7.0 - Use NSShadowAttributeName with an NSShadow instance as the value.，请尝试此操作。
NSShadow *shadow = [[NSShadow alloc] init];
shadow.shadowColor = [UIColor grayColor];
shadow.shadowOffset = CGSizeMake(0.0, 0.5);
NSDictionary *attribute = [NSDictionary dictionaryWithObjectsAndKeys:
[UIFont fontWithName:@"AmericanTypewriter" size:10.0f], NSFontAttributeName,
[UIColor blackColor], NSForegroundColorAttributeName,
shadow,NSShadowAttributeName,nil];
[[UITabBarItem appearance] setTitleTextAttributes:attribute forState:UIControlStateNormal];

Sorry, I dont think there's a way to do this. If you're desperate, you'll need to write your own tab bar.
抱歉，我认为没有办法做到这一点。如果您感到绝望，则需要编写自己的标签栏。

Sadly, this isn't possible currently on iOS unless you build your own custom tab bar, which isn't very difficult with storyboarding on iOS5.
遗憾的是，这在 iOS 上目前是不可能的，除非您构建自己的自定义标签栏，这对于 iOS5 上的故事板来说并不是很困难。

Not possible ,create custome tab bar subclassing UITabbar
不可能，创建自定义标签栏子类化 UITabbar
