UITextAttributeTextColor的问题

objc中使用UITextAttributeTextColor

    [[UITabBarItem appearance] setTitleTextAttributes:[NSDictionary dictionaryWithObjectsAndKeys:navigationBarColor,UITextAttributeTextColor, nil] forState:UIControlStateSelected];

swift中使用NSForegroundColorAttributeName

   UITabBarItem.appearance().setTitleTextAttributes([NSForegroundColorAttributeName:navigationBarColor], forState: UIControlState.Selected)

Wrong:’UITextAttributeTextColor‘ is unavailable: Use NSForegroundColorAttributeName            

UITabBarItem.appearance().setTitleTextAttributes([UITextAttributeTextColor:navigationBarColor], forState: UIControlState.Selected)

objc

NSDictionary dic = [NSDictionary dictionaryWithObjectsAndKeys:navigationBarColor,UITextAttributeTextColor, nil] 

equals

NSDictionary dic = [UITextAttributeTextColor:navigationBarColor]
