ios - 安全区域的根 View Controller 偏移量问题

出现根视图控制器时，该视图似乎与安全区域冲突

但是当我更改选项卡并再次回到该选项卡时，似乎一切正常

编辑:

class Switcher {

static func updateRootVC(){

    let status = UserDefaults.standard.object(forKey: "Accesstoken")
    let userID = UserDefaults.standard.object(forKey: "UserId")
    let userName = UserDefaults.standard.object(forKey: "UserName")
    let userImage = UserDefaults.standard.object(forKey: "UserImage")

    if let currentUser = userID {
        requestManager.instance.userID = currentUser as! Int
    }
    if let currentStatus = status {
        requestManager.instance.getToken = currentStatus as? String
    }
    if let Name = userName {
        Api.Params.inputUserName = (Name as? String)!
    }
    if let Image = userImage {
        Api.Params.inputUserImage = (Image as? String)!
    }


    var rootVC : UIViewController?

    if(status != nil){
        rootVC = UIStoryboard(name: "Tabbar", bundle: Bundle.main).instantiateViewController(withIdentifier: "Tabbar") as! UITabBarController
    } else {
        rootVC = UIStoryboard(name: "Main", bundle: Bundle.main).instantiateViewController(withIdentifier: "welcome") as! UINavigationController
    }

    rootVC!.view.insetsLayoutMarginsFromSafeArea = true


    let appDelegate = UIApplication.shared.delegate as! AppDelegate
    appDelegate.window?.rootViewController = rootVC
    appDelegate.window?.makeKeyAndVisible()

}}

用户个人资料与搜索项的顶部相同。

最佳答案

尝试使用insetsLayoutMarginsFromSafeArea属性从safeArea指定视图插图布局:

rootVC.view.insetsLayoutMarginsFromSafeArea = true
