当另一个viewController隐藏状态栏时，UINavigationBar在状态栏下移动

Question

问题很简单，个人资料viewController在状态栏下方有一个NavigationBar 我将另一个viewController推到当前的viewController之上。 这个新的viewController会隐藏状态栏。

当我返回个人资料navigationBar时，viewWillAppear已经向上移动了状态栏高度的大小。

我尝试在我的public static ExecuteMultipleRequest MultipleRequest { get; set; } private const int BatchSize = 250; public static long LastBatchTime { get; set; } private static void Batch(IOrganizationService service, OrganizationRequest request) { if (MultipleRequest.Requests.Count == BatchSize) { ExecuteBatch(service); } MultipleRequest.Requests.Add(request); } private static void ExecuteBatch(IOrganizationService service) { if (!MultipleRequest.Requests.Any()) { return; } Log("Executing Batch size {0}. Last Batch was executed in {1}",MultipleRequest.Requests.Count, LastBatchTime); var watch = new System.Diagnostics.Stopwatch(); watch.Start(); var response = (ExecuteMultipleResponse)service.Execute(MultipleRequest); watch.Stop(); LastBatchTime = watch.ElapsedMilliseconds; Log("Completed Executing Batch in " + watch.ElapsedMilliseconds); WriteLogsToConsole(); var errors = new List<string>(); // Display the results returned in the responses. foreach (var responseItem in response.Responses) { // A valid response. if (responseItem.Fault != null) { errors.Add(string.Format( "Error: Execute Multiple Response Fault. Error Code: {0} Message {1} Trace Text: {2} Error Keys: {3} Error Values: {4} ", responseItem.Fault.ErrorCode, responseItem.Fault.Message, responseItem.Fault.TraceText, responseItem.Fault.ErrorDetails.Keys, responseItem.Fault.ErrorDetails.Values)); } } MultipleRequest.Requests.Clear(); if (errors.Any()) { throw new Exception(string.Join(Environment.NewLine, errors)); } } 中强制进行布局刷新，但它不起作用。

有什么想法吗？

Answer 1

使用以下代码，

override func viewWillDisappear(animated: Bool) {
    navigationController?.setNavigationBarHidden(navigationController?.navigationBarHidden == false, animated: false)
}

希望它有用

Answer 2

在显示的viewcontroller中实现viewDidDisappear并在进入profileview控制器之前再次显示状态栏。

  override func viewWillDisappear(animated: Bool) {


    UIApplication.sharedApplication().setStatusBarHidden(false, withAnimation: UIStatusBarAnimation.Fade)
}

Answer 3

在应用中的plist文件隐藏状态栏中添加代码：

<key>UIViewControllerBasedStatusBarAppearance</key>
<false/>
