问题描述

我正在开发一个小应用程序，我想将默认的全局色调颜色从蓝色更改为橙​​色.我已经在Objective-C中看到了许多方法来执行此操作，但是我似乎无法使用Swift使其正常工作.我怎样才能做到这一点?预先感谢！

I'm developing a little app and I would like to change the default global tint color from blue to orange. I've seen many ways to do it in Objective-C but I can't seem to get it to work using swift. How could I achieve this? Thanks in advance!

推荐答案

此答案最后一次针对Swift 5.2和iOS 13.5 SDK进行了修订.

您可以在窗口上设置 tintColor .由于色调颜色会向下级联到所有子视图(除非明确覆盖)，因此将其设置在窗口上将有效地使其在该窗口内变为全局.

You can set the tintColor on your window. Because tint color cascades down to all subviews (unless explicitly overridden), setting it on a window will effectively make it global inside that window.

将以下行添加到您的 application(_:didFinishLaunchingWithOptions:) 或<在使窗口键可见之前，先创建一个href ="https://developer.apple.com/documentation/uikit/uiscenedelegate/3197914-scene" rel ="nofollow noreferrer"> scene(_:willConnectTo:options:) :

Add the following line to your application(_:didFinishLaunchingWithOptions:) or scene(_:willConnectTo:options:) just before making the window key and visible:

window.tintColor = .systemOrange /* or .orange on iOS < 13 */

您还可以通过更改Global Tint属性在情节提要中进行设置:

You can also set in in the storyboard by changing the Global Tint property:
