Dear Kia111,
It is possible. What you can do is, insert a radio button group and set the appearance as "checkbox". In this case, you radio button group will appear as if two checkboxes are placed. But, the behavior will be the way you wanted. Checking one radio button (checkbox) will uncheck the other and vice-versa.
In this case, you need to tweak your code based on the binding values set for each radio button in the radio button group. For eg., say if 1 and 2 are the binding values for two radio buttons:
if(chkbox.rawValue == "1")
{
section.presence = "visible";
}
else
{
section.presence = "hidden";
}
Hope this helps.
Thanks,
VJ
