更改照片库按钮的颜色

Question

我想更改 "Cancel" 按钮的颜色以及从照片库中选择图像时显示的其他按钮的颜色。我怎样才能做到这一点？

var imagePicker = UIImagePickerController()
imagePicker.delegate = sender as? protocol<UIImagePickerControllerDelegate, UINavigationControllerDelegate>
imagePicker.sourceType = UIImagePickerControllerSourceType.PhotoLibrary
imagePicker.allowsEditing = true
sender.navigationController?.presentViewController(imagePicker, animated: true, completion: nil)

Answer 1

Objective - C

在您的 AppDelegate.m

中添加以下代码

[[UINavigationBar appearance] setTintColor:[UIColor whiteColor]];

Swift

在AppDelegate.swift中，在application(_:didFinishLaunchingWithOptions:)中我输入了以下内容：

UINavigationBar.appearance().tintColor = UIColor.whiteColor()

如果您想更改导航栏的文本颜色，请使用以下代码：

UINavigationBar.appearance().titleTextAttributes = [NSForegroundColorAttributeName : UIColor.whiteColor()]
