设置tabbar背景为透明，我按照网上的设置backgroundcolor没有达到我的效果
于是设置图片：
继承类UITabBarController的viewDidLoad() 中
self.tabBar.backgroundImage = imageWithColor(color: UIColor(red: 0, green: 0, blue: 0, alpha: 0.2))
在底下写这个方法
func imageWithColor(color: UIColor) -> UIImage? {
let rect = CGRect(x: 0.0, y: 0.0, width: 1.0, height: 1.0)
UIGraphicsBeginImageContext(rect.size)
let context = UIGraphicsGetCurrentContext()
context?.setFillColor(color.cgColor)
context?.fill(rect)
let image = UIGraphicsGetImageFromCurrentImageContext()
UIGraphicsEndImageContext()
return image
}
自定义文字选择和未选中颜色：
自定义的UITabBarController 的viewDidLoad() 中
UITabBarItem.appearance().setTitleTextAttributes([NSAttributedString.Key.foregroundColor: UIColor(red: 156/255.0, green: 179/255.0, blue: 184/255.0, alpha: 1.0)], for: .normal)
UITabBarItem.appearance().setTitleTextAttributes([NSAttributedString.Key.foregroundColor: UIColor.white], for: .selected)
设置图片原本的颜色
自定义的UITabBarController
override func awakeFromNib() {
self.tabBar.items?.forEach({ (it) in
it.image = it.image?.withRenderingMode(.alwaysOriginal)
it.selectedImage = it.selectedImage?.withRenderingMode(.alwaysOriginal)
})
}
