• UISearchBar is flickering in UINavigationBar with Large Titles

  I'm creating a UINavigationController-based app and want to do it in iOS 12 style: with large titles and the Search Bar displayed inside the Navigation Bar.

  Unfortunately, I have this problem that the Search Bar will briefly disappear as soon as the animation to the next (or previous) View Controller starts. Once the animation is finished, the Search Bar is visible again. One has to look closely to see it, but if you use the swipe gesture to go back you can see the effect very good.

  UISearchBar disappeares when animation between View Controller starts

  In order to reproduce the issue outside of my full app I created a simple little app with a UINavigationController as initial View Controller and a plain View Controller (with just a "Next" Button) as Root View Controller in there. Large Titles are set to Automatic in the Navigation Item, and on the Navigation Bar "Prefers Large Titles" is set to True. In viewDidLoad in the view controller I assign an instance of UISearchBar() to the Navigation Item as simple as this:

  class ViewController: UIViewController {
      override func viewDidLoad() {
          super.viewDidLoad()
  
          let searchController = UISearchController(searchResultsController: nil)
          navigationItem.searchController = searchController
      }
  }
  

  The "Next" button has a "Show" seague to its surrounding View Controller, so I will be able to push the same View Controller over and over again for testing.

  What I want is the same behavior as in the iOS 12 Files App: There, the Search Bar remains static within the Navigation Bar even when navigation happens.

  I already spent some good time searching for a solution but could not really find something.

• Missing required modules after installing new cocoapod

  I have a project that's using several custom frameworks. These custom frameworks have some pods as dependencies like Alamofire, SwiftKeychainWrapper, etc., so I have these installed in my main project.

  Everything works just fine until I try to install a new pod ('RealmSwift') that a new custom framework has a dependency on. After I install it I get this error:

  diff: /Podfile.lock: No such file or directory
  diff: /Manifest.lock: No such file or directory
  error: The sandbox is not in sync with the Podfile.lock. Run 'pod install' or update your CocoaPods installation.

  I'm able to resolve this by adding two USER_DEFINED build settings for PODS_PODFILE_DIR_PATH and PODS_ROOT (but why did running pod install change this?)

  Then when I try to build, all my custom frameworks that have pods as dependencies give this error when trying to import:

  Example:
  Missing required modules: 'Alamofire', 'SwitfKeychainWrapper', etc.

  Why can't Xcode see these modules? They're exactly where they were before.

  I've tried everything to resolve this. Cleaning, deleting derived data, deintegrating my pods and reinstalling all of them, editing the import paths and header search paths, nothing seems to work.

  I'd be so grateful for any help!
• When I swipe the tableview, how do I put these items on it?

  This is the Actual design that I want to make in my tableview swipe.

  
• SocketIO freezes IOS app when reconnection

  I've noticed that whenever I restart the NodeJS SocketIO server with (CTRL+C) 5-6 times, my iOS Chat Application freezes.

  Not instantly, but when I hit the back button, or the keyboard has to show up.

  ---

  I'm sure that it is because of the (CTRL+C) way of restarting the server.

  Maybe I'm handling the reconnection in a bad way. :/

  • Server Side: When connecting, first I check if socket.id has not yet been registered
  • Then I check if userID is already associated to a socket, if so, disconnect the previous sockets.

  And maybe that causes the problem.

  Server Code:

  var app = require('express')(); // app
  var server = require('http').Server(app); // on http create server
  var io = require('socket.io')(server);
  var socketioJwt = require("socketio-jwt"); // JWT for authentication
  
  var mysql = require('mysql');
  var pool = mysql.createPool({
      connectionLimit: 100,

      if (targetSocket == null && socket.decoded_token.userId != null) {
  
          var userId = socket.decoded_token.userId;
  
          // Disconnect older clients who are associated with differen socket.id but same userId

• Swift performance on optional UI elements

  Setting up a UILabel in Swift I can do the following

  @IBOutlet var wLabel: UILabel!
  

  or

  @IBOutlet var wLabel: UILabel?
  

  Setting the text I can either do

  wLabel.text = "..."
  

  or, for the latter do

  wLabel?.text = "..." // with a question mark for the optional
  

  Keeping them optional will help for the case when they are unexpectedly nil as it will just skip this call then and go ahead with the code. Having them declared with the ! would crash the app if the label was nil.

  Now why would you not make everything optional? The only reason I could think of would be for better performance. Should I stay away from having them optional if my app has a lot of UI elements so them being optional would mean a disadvantage regarding performance? I wasn't able to find any information on this anyhere.
• Swift 4 WebkitView URL change not doing its job

  I am having the following situation.

  I am using a WebkitView to display some session information. In most places it's generated when the ViewController comes to life, but I have one particular view in which I have to reload it on user interactions with buttons that change to next or previous month.

  I have the following code:

  // This is my connection to the storyboard element
  @IBOutlet weak var areaNotasMes: WKWebView!
  

  After that I have a function that does the URL handling:

  func actualizarUrlNotasMes(fechaNueva: Date) {
      let formateadorAdicional = DateFormatter()
      formateadorAdicional.dateFormat = "yyyyMM"
  
      let url = URL(string: "https://myurl/\(formateadorAdicional.string(from: fechaNueva))")
  
      areaNotasMes.load(URLRequest(url: url!))
  }
  

  And I have a button event that uses the function with the next YEAR_MONTH combination like this:

  @IBAction func mesSigPressed(_ sender: UIButton) {
      // Some more code to get the fechaActual variable
      actualizarUrlNotasMes(fechaNueva: fechaActual)
      // Some more code
  }
  

  So, basically what's happening is that it loads the first time I open the ViewController, but when I click on the button to change to the next month, the date gets changed, correctly generated and passed to the function. It generates the correct URL, but when the areaNotasMes.load(...) function runs, nothing refreshes on the WebKitView. I tried adding areaNotasMes.reload(), but it also did nothing. Do I have to like destroy and recreate the WebKitView each time I change the URL? Or am I not handling the URL change correctly?

  Also, the console pops up some of these messages from time to time, not always:

  [BoringSSL] nw_protocol_boringssl_get_output_frames(1301) [C5.1:2][0x7fea2d201de0] get output frames failed, state 8196

  Any good frameworks out there that help in the process of posting pictures to your photography page in your portfolio website?

• Building a Framework that allows to import multiple files and parse them

  What I want to do: As part of a project, I need to build a framework that allows the user to import files (say a bunch of Python scripts or some JSON files) and parses them. The parsed results are mapped to a data model (at the moment I decided on a tree structure where the nodes correspond to the parsed lines in a file).

  Requirements: The framework should allow different parsers to be compatible with it i.e., the user can 'fit' different parsers as and when required.

  I was thinking of Java to build this but I am open to other suggestions.

  Now, I know this might sound too broad but I would like to get an idea about an outline I should follow to implement this. I have never implemented a framework before and some guidance as to where to start and how to go about it would be very helpful.
• Can I upload same applications into App store?

  I could not find such a rule, but I want to be sure.

  I need to publish it this way, because different versions work with different servers, in one app it cannot be done according to the system requirements.

• Datepicker period calculating

  I am having this problem for about two years now. I want to use (3) datetimepickers to find the period from two dates whether it is behind or ahead using local time (US). Not going international settings for this way to much based on TZ. Based on the initial period from first two dates, i the use a third date-time to find an offset of the initial Date-time period.

  (1) I dont want to use ABS not what i was looking for based on search results on line and here.

  (2) Time will differ from years to the minute that needs to be displayed on all datetimepickers.

  Documentation from Oracle, Joda, JAVA have been downloaded I do believe my question is different from multiple searches.

  [Oracle:

  public static Period between(LocalDate startDateInclusive, LocalDate endDateExclusive)

  Obtains a Period consisting of the number of years, months, and days between two dates. The start date is included, but the end date is not. The period is calculated by removing complete months, then calculating the remaining number of days, adjusting to ensure that both have the same sign. The number of months is then split into years and months based on a 12 month year. A month is considered if the end day-of-month is greater than or equal to the start day-of-month. For example, from 2010-01-15 to 2011-03-18 is one year, two months and three days.

  The result of this method can be a negative period if the end is before the start. The negative sign will be the same in each of year, month and day.

  Parameters: startDateInclusive - the start date, inclusive, not null endDateExclusive - the end date, exclusive, not null Returns: the period between this date and the end date, not null]

  [Joda:

  DateTime(int year, int monthOfYear, int dayOfMonth, int hourOfDay, int minuteOfHour) Constructs an instance from datetime field values using ISOChronology in the default time zone.]

  I still would like to include the months as well
