In this way:
$('#btn').click(function(){
if($( '#mycheckbox' ).prop( "checked" ) == true){
alert('desmarcado')
$( '#mycheckbox' ).prop( "checked" , false)
} else {
alert('marcado')
$( '#mycheckbox' ).prop( "checked" , true)
}
})
See the example working on here link

HTML:
<ul class="chk-container">
<li><input type="checkbox" id="selecctall"/> Selecionar todos</li>
<li><input class="checkbox1" type="checkbox" name="check[]" value="item1">Item #01</li>
<li><input class="checkbox1" type="checkbox" name="check[]" value="item2">Item #02</li>
<li><input class="checkbox1" type="checkbox" name="check[]" value="item3">Item #03</li>
</ul>
JS:
$(document).ready(function() {
$('#selecctall').click(function(event) {
if(this.checked) {
$('.checkbox1').each(function() {
this.checked = true;
});
}else{
$('.checkbox1').each(function() {
this.checked = false;
});
}
});
});
