我需要使用Helvetica Neue Light字体。以下是我创建控制器的方式:
let picker: UIImagePickerController = UIImagePickerController()
picker.delegate = self
picker.allowsEditing = false
picker.navigationBar.tintColor = UIColor.whiteColor()
picker.sourceType = .PhotoLibrary
picker.navigationController?.navigationBar.tintColor = UIColor.blueColor()
self.presentViewController(picker, animated: true, completion: { _ in })
picker.navigationBar.titleTextAttributes
了吗? - Yunus Eren Güzel
