swift - Error in pageviewcontroller cannot convert [AnyObject] to expected arguments -


i new ios developer , doing pageviewcontroller in take 4 labels , these 4 label while shown on each screen respectively.but getting error while taking in array in code in have shown

var pageviewcontroller:uipageviewcontroller! var label:nsarray! override func viewdidload() {     super.viewdidload()     // additional setup after loading view, typically nib.     self.label = nsarray(objects: "1", "2", "3", "4")      self.pageviewcontroller = self.storyboard?.instantiateviewcontrollerwithidentifier("pageviewcontroller") as! uipageviewcontroller      self.pageviewcontroller.datasource = self      var startvc = self.viewcontrolleratindex(0) contentviewcontroller     var viewcontrollers = nsarray(object: startvc)

self.pageviewcontroller.setviewcontrollers(viewcontrollers [anyobject], direction: .forward, animated: true, completion: nil)

    self.pageviewcontroller.view.frame = cgrectmake(0, 0, self.view.frame.width, self.view.frame.size.height - 50)      self.addchildviewcontroller(self.pageviewcontroller)     self.view.addsubview(self.pageviewcontroller.view)     self.pageviewcontroller.didmovetoparentviewcontroller(self) }

in line getting error of object cannot shown expected arguments

that's because you're passing array of anyobjects uipageviewcontroller's setviewcontrollers(_:direction:animated:completion:) method. expects array of uiviewcontrollers. change piece of code this:

var startvc = self.viewcontrolleratindex(0) contentviewcontroller self.pageviewcontroller.setviewcontrollers([startvc], direction: .forward, animated: true, completion: nil)

also shouldn't use nsarrays in swift. use standard swift arrays instead.

c# - Check Keyboard Input Winforms -

i wondering if instead of doing this protected override void onkeydown(keyeventargs e) { if (e.keycode == keys.a) console.writeline("the key down."); } i set bool method , this: if(keydown(keys.a)) // whatever here i've been sitting here ages trying figure out how it. can't wrap head around it. in case wondering, plan call bool inside different method, check input. since want perform action after pressing key, using keydown event enough. but in cases suppose want check if specific key down in middle of process, can use getkeystate method way: [dllimport("user32.dll", charset = charset.auto, exactspelling = true)] public static extern short getkeystate(int keycode); public const int key_pressed = 0x8000; public static bool iskeydown(keys key) { return convert.toboolean(getkeystate((int)key) & key_pressed); } you should know, each time check key state using example iskeydown(keys.a) method returns true if ke...
