修改UITabBarItem字体颜色

• 修改UITabBarItem下面字体的颜色，如图：

  
  

  [[UITabBarItemappearance]setTitleTextAttributes:[NSDictionarydictionaryWithObjectsAndKeys:[UIColorblackColor],UITextAttributeTextColor,nil]forState:UIControlStateNormal];

  [[UITabBarItemappearance]setTitleTextAttributes: [NSDictionarydictionaryWithObjectsAndKeys:[UIColorredColor],UITextAttributeTextColor,nil]forState:UIControlStateSelected];

  这个时候会报警告'UITextAttributeTextColor' is deprecated in iOS 7. The iOS 7 key is 'NSForegroundColorAttributeName

  然后替换一下就可以了，不过NSForegroundColorAttributeName最底支持到ios6.0

  [[UITabBarItemappearance]setTitleTextAttributes:[NSDictionarydictionaryWithObjectsAndKeys:[UIColorblackColor],NSForegroundColorAttributeName,nil]forState:UIControlStateNormal];

  [[UITabBarItemappearance]setTitleTextAttributes: [NSDictionarydictionaryWithObjectsAndKeys:[UIColorredColor],NSForegroundColorAttributeName,nil]forState:UIControlStateSelected];

  以上是改变字体颜色的，图片颜色无法改变，

  [[UITabBarappearance]setTintColor:[UIColorredColor]];

  但是上面这一句就可以改变并设置点击后的图片和文字颜色了。
