tabbaritemのフォントサイズの変更

タブのフォントサイズを変更することはできますか？

私は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];
}

IN Swift 2.0

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)

}

Swift 3.0

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)
}

[更新] @ cancer86のiOS 7.0以降のバージョンのいい答え：

[[UITabBarItem appearance] setTitleTextAttributes:[NSDictionary dictionaryWithObjectsAndKeys:
                                                   [UIColor whiteColor], NSForegroundColorAttributeName,
                                                   [UIFont fontWithName:@"Helvetica" size:tabFontSize],
                                                   NSFontAttributeName,
                                                   nil] forState:UIControlStateNormal];

[[UITabBarItem appearance] setTitleTextAttributes:[NSDictionary dictionaryWithObjectsAndKeys:
                                                   [UIColor redColor], NSForegroundColorAttributeName,
                                                   [UIFont fontWithName:@"Helvetica" size:tabFontSize], NSFontAttributeName,
                                                   nil] forState:UIControlStateSelected];

主な変更は、UITextAttributeTextColorとUITextAttributeFontの両方が非推奨であることです。

すべてのタブに適用するには（@ToolmakerSteveに指摘してくれてありがとう）

for(UIViewController *tab in  self.tabBarController.viewControllers)
{        
    [tab.tabBarItem setTitleTextAttributes: ...];
}

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];
        }
    }
}

IN Swift 4

 override func viewDidLoad() {
        super.viewDidLoad()
        let appearance = UITabBarItem.appearance()
        let attributes: [NSAttributedString.Key: AnyObject] = [NSAttributedString.Key(rawValue: NSAttributedString.Key.font.rawValue):UIFont(name: "American Typewriter", size: 12)!, NSAttributedString.Key(rawValue: NSAttributedString.Key.foregroundColor.rawValue): UIColor.orange]
        appearance.setTitleTextAttributes(attributes, for: .normal)

    }

[ここに私の参照用に残しますが、他の実用的な答えのほんの一部です。 memにとっては、これはiOS 7の修正であり、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

不足しているメソッドは

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

これはSwiftであると思いますが、タブバーの色とテキスト属性を明確に制御できます。

class MyTabBarController: UITabBarController {

  override func viewDidLoad() {
    super.viewDidLoad()
    tabBar.barTintColor = UIColor.green

    UITabBarItem.appearance().setTitleTextAttributes(
        [NSAttributedString.Key.font:UIFont.boldSystemFont(ofSize: 18), 
           NSAttributedString.Key.foregroundColor: UIColor.orange], for: .normal)
...

実際には方法があります。

    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]];
            }
        }
    }
}
