より良い方法をお勧めします：

[yourTabBarItem setTitleTextAttributes:[NSDictionary dictionaryWithObjectsAndKeys:
    [UIColor whiteColor], UITextAttributeTextColor, 
    [NSValue valueWithUIOffset:UIOffsetMake(0,0)], UITextAttributeTextShadowOffset, 
    [UIFont fontWithName:@"Helvetica" size:18.0], UITextAttributeFont, nil]
    forState:UIControlStateNormal];

for(UIViewController *tab in  self.tabBarController.viewControllers)

{        
  [tab.tabBarItem setTitleTextAttributes:[NSDictionary dictionaryWithObjectsAndKeys:
  [UIFont fontWithName:@"Helvetica" size:20.0], UITextAttributeFont, nil]
  forState:UIControlStateNormal];
}

Swift 2.0 で

override func viewDidLoad() {
    super.viewDidLoad()

   let appearance = UITabBarItem.appearance()
   let attributes: [String: AnyObject] = [NSFontAttributeName:UIFont(name: "American Typewriter", size: 12)!, NSForegroundColorAttributeName: UIColor.orangeColor()]
   appearance.setTitleTextAttributes(attributes, forState: .Normal)

}

スウィフト 3.0 では

override func viewDidLoad() {
    super.viewDidLoad()

    let appearance = UITabBarItem.appearance()
    let attributes: [String: AnyObject] = [NSFontAttributeName:UIFont(name: "American Typewriter", size: 12)!, NSForegroundColorAttributeName: UIColor.orange]
    appearance.setTitleTextAttributes(attributes, for: .normal)
}

iOS 5.0 以降ではシンプル:

[[UITabBarItem appearance] setTitleTextAttributes:@{UITextAttributeFont:[UIFont boldSystemFontOfSize:15]} forState:UIControlStateNormal];

TabBarIncreaseFonts(self.tabBarController);


void TabBarIncreaseFonts(UITabBarController* customTabBarController)
{

    for(UIView* controlLevelFirst in [customTabBarController.tabBar subviews])
    {

        if(![controlLevelFirst isKindOfClass:NSClassFromString(@"UITabBarButton")])
            continue;

        for(id controlLevelSecond in [controlLevelFirst subviews])
        {
            [controlLevelSecond setBounds: CGRectMake(0, 0, 100, 48)];

            if(![controlLevelSecond isKindOfClass:NSClassFromString(@"UITabBarButtonLabel")])
                 continue;

             [controlLevelSecond setFont: [UIFont boldSystemFontOfSize:20]]; 
             [controlLevelSecond setFrame: CGRectMake(0, 0, 96, 48)];
             [controlLevelSecond setTextAlignment:UITextAlignmentCenter];
        }
    }
}

[これは私自身の参考のためにここに残しておきます。他の有効な回答からの単なるリフです。私にとっては、これはiOS 7の修正であり、これは少し問題を超えています...]

@implementation UITabBarController (Util)

- (void) fixForIos7 {
    if (!IS_IOS7)
        return;
    UIFont *tabBarFont = [UIFont systemFontOfSize:12];
    NSDictionary *titleTextAttributes = [NSDictionary dictionaryWithObjectsAndKeys:
            tabBarFont, UITextAttributeFont, nil];
    for(UIViewController *tab in  self.viewControllers) {
      [tab.tabBarItem setTitleTextAttributes:titleTextAttributes forState:UIControlStateNormal];
    }
}
@end

欠けている方法は

#define IS_IOS7 ( UIDevice.currentDevice.systemVersion.floatValue > 6.9 )

実は方法があります。

    NSMutableArray *tabBarItems = [[[[[self.view subviews] objectAtIndex:1] subviews] mutableCopy] autorelease];

for (int item = 0; item < [tabBarItems count]; item++) {
    for (int subview = 0; subview < [[[tabBarItems objectAtIndex:item] subviews] count]; subview++) {
        for (int item = 0; item < [tabBarItems count]; item++)  {
            for (int subview = 0; subview < [[[tabBarItems objectAtIndex:item] subviews] count]; subview++)  {
                if ([[[[tabBarItems objectAtIndex:item] subviews] objectAtIndex:subview] isKindOfClass:NSClassFromString(@"UITabBarButtonLabel")]) 
                    [[[[tabBarItems objectAtIndex:item] subviews] objectAtIndex:subview] setFont:[UIFont systemFontOfSize:6.0f]];
            }
        }
    }
}

Xcode 13 および Swift 5+

カスタム拡張クラスからタブバー項目のフォント属性を変更できます。

例えば、

拡張ファイル (.swift) を作成し、次のコードを配置します

UIKitのインポート

@IBDesignable
extension UITabBarItem {

@IBInspectable var fontSize : CGFloat{
    set{
        if(newValue > 0){
            let barItemFontAttributes = [NSAttributedString.Key.font : UIFont(name: "Avenir", size: newValue)]
            self.setTitleTextAttributes(barItemFontAttributes as [NSAttributedString.Key : Any], for: .normal)
        }
    }
    get{
        return self.fontSize
    }
}

属性インスペクターからフォントサイズを変更できるようになりました

より良い方法があれば、それについて言及してください！
