ios - UIButton text content keeps resetting every second update -


i trying update button test value , have noticed every second update button title text shows test value fraction of second resets button's default value.

it seems bug, wanted see if there simpler explanation. have tried waiting 10 seconds before pushing button seems consistently occurring.

any ideas how make uibutton function expected?

import uikit  class viewcontroller: uiviewcontroller {      var testentry = "its working"     @iboutlet weak var testbutton: uibutton!     @iboutlet weak var testlabel: uilabel!      @ibaction func runtest(sender:         uibutton) {         // button value should equal value of label value, every 2nd button press of test button results in title of button value resetting default value         dispatch_async(dispatch_get_main_queue()) {             self.testlabel.text = "\(self.testentry)"             self.testbutton.titlelabel?.text = "\(self.testentry)"         }     }

here github project.

you shouldn't directly setting text of button title label, should set font directly onto label. text should set calling

func settitle(_ title: string?, forstate state: uicontrolstate)

the text toggles because you're selecting , de-selecting button, switching between of states have different titles.

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...
