我已经定制了TabBar这样的外观

UIImage *tabBackground = [[UIImage imageNamed:@"tab-bar-bg.png"] resizableImageWithCapInsets:UIEdgeInsetsMake(0, 0, 0, 0)];
[[UITabBar appearance] setBackgroundImage:tabBackground];
[[UITabBar appearance] setSelectionIndicatorImage: [UIImage imageNamed:@"activetab.png"]];

如何定义自定义字体以及选定和未选定的文本颜色？

谢谢,
