修改UITabBarItem字型顏色

修改UITabBarItem下面字型的顏色，如圖：

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

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

這個時候會報警告'UITextAttributeTextColor' is deprecated in iOS 7. The iOS 7 key is 'NSForegroundColorAttributeName

然後替換一下就可以了，不過NSForegroundColorAttributeName最底支援到ios6.0

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

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

以上是改變字型顏色的，圖片顏色無法改變，

[[UITabBarappearance]setTintColor:[UIColorredColor]];
