c# - Add/remove EventHandler for UIBarButtonItem -

-

one can define eventhandler in constructor:

uibarbuttonitem logoutbutton = new uibarbuttonitem (uibarbuttonsystemitem.stop, logoutbuttoneventhandler);  private void logoutbuttoneventhandler(object sender, eventargs args){     console.writeline("logout"); }

is possible remove eventhandler afterwards? perhaps not using eventhandler @ , instead use action/target properties of uibarbuttonitem? don't find examples. anonymous methods used time.

how do that?

instantiate object , set handler:

var logoutbutton = new uibarbuttonitem (uibarbuttonsystemitem.stop) logoutbutton.clicked += logoutbuttoneventhandler;

to remove afterwards use -= syntax:

 logoutbutton.clicked -= logoutbuttoneventhandler;

just beware of commom pitfalls when because may cause memory leaks.

javascript - Handling constructor related functions while testing with mocha and sinon -

i testing application in declare specific variable within constructor , assign return of function imported class. how code looks like: var someclass; function constructor() { this.someclasshandler = null; } constructor.prototype.newsomeclass = function() { someclass = require('./someclass.js'); return new someclass(); } constructor.prototype.getfunction = function() { this.someclasshandler = this.newsomeclass(); } constructor.prototype.callsomefunction = function() { this.someclasshandler.somefunction(); } when try test code whether function 'somefunction' imported class 'someclass' called within method'callsomefunction' receive failed test responses variable 'someclasshandler' still equals null (which makes sense not call method 'getfunction' assigns class variable). i use mocha , sinon tests, bit helpless whether mock or stub class in order assign variable 'this.someclasshandler' correctly. the m...
