iOS App 仿小红书刘海 Logo 实现，效果如下：
关键代码：
class AppDelegate: UIResponder, UIApplicationDelegate {
var window: UIWindow?
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
// Override point for customization after application launch.
self.window = UIWindow(frame: UIScreen.main.bounds)
self.window?.rootViewController = ViewController()
self.window?.backgroundColor = UIColor.white
self.window?.makeKeyAndVisible()
// 添加 Logo
if (UIDevice.isiPhoneXSeries) {
let labelSize: CGSize = CGSize(width: 50, height: 20)
let label: UILabel = UILabel(frame:
CGRect(
x: (UIScreen.main.bounds.size.width - labelSize.width) / 2,
y: 5,
width: labelSize.width,
height: labelSize.height
)
)
label.text = "小红书"
label.textAlignment = .center
label.font = UIFont.pingFangSCBoldItalic(ofSize: 12)
label.backgroundColor = UIColor(hexRGB: 0xf03b3f)
label.textColor = UIColor(hexRGB: 0xfffffd)
label.layer.cornerRadius = labelSize.height / 2
label.clipsToBounds = true
label.tag = 2333
self.window?.addSubview(label)
self.window?.bringSubviewToFront(label)
}
return true
}
func applicationWillResignActive(_ application: UIApplication) {
// 隐藏 Logo
if let label = self.window?.viewWithTag(2333) {
label.isHidden = true
}
}
func applicationDidBecomeActive(_ application: UIApplication) {
// 显示 logo
if let label = self.window?.viewWithTag(2333) {
label.isHidden = false
}
}
}
