Changing the background color of Tab Bar
提问by MrDank
I am trying to get desired color rendered in the background of Tab Bar however I am facing problems. These are the things that I tried :-
我正在尝试在 Tab Bar 的背景中呈现所需的颜色，但是我遇到了问题。这些是我尝试过的事情：-
Changing the background color of tab bar object from storyboard. The color rendered is always lighter than the desired color.
Programmatically changing the color of the tab bar using the following code inside
viewDidLoad()methodself.tabBar.translucent = false self.tabBar.backgroundColor = UIColor(hexString: "323B61")It doesn't change the color. Instead , the color rendered is white.
从故事板更改标签栏对象的背景颜色。渲染的颜色总是比所需的颜色浅。
使用以下代码内
viewDidLoad()方法以编程方式更改选项卡栏的颜色self.tabBar.translucent = false self.tabBar.backgroundColor = UIColor(hexString: "323B61")它不会改变颜色。相反，呈现的颜色是白色。
