ios - IBOutlet for image button not correctly referencing button after recreating outlet -


i have custom button image. have iboutlet reference in viewcontroller.swift file.

the button working hooked wrong outlet. removed of outlets , actions button , similar buttons , remade them. @ point stopped working.

i first tried change image button code: 

star1backbuttonreference.setimage(uiimage(named: "starfull_48dp.png"), forstate:

this didn't anything. after thinking problem code changing image decided check few things.

so tried hide button this:

star1backbuttonreference.hidden = true

this did not either think there problem iboutlet reference star1backbuttonreference , found instance change/hide image , reference.

the reference this:

@iboutlet var star1backbuttonreference: uibutton!

i checked referencing outlet on storyboard , correct (one side viewcontroller other side star1backbuttonreference).

there must mistake have done in connecting outlet or deleting old one.

if deleting referencing outlet must remove it's reference connection inspector.

so, once delete outlet button , select button storyboard , click on connection inspector , press x outlets under referencing outlets in connection inspector.

so, have deleted iboutlet code , close it's connection also.

now ctrl + drag button relevant viewcontroller opened in assistant editor , popup appear, make sure outlet selected beside connection , set it's name whatever want , press connect. that's it. try newly connected outlet.

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...
