Hey Namratha  If you re asking about changing the text and enabled disabled state of a UIButton  it can be done pretty easily as follows    myButton setTitle   Normal State Title  forState UIControlStateNormal      To set the title  myButton setEnabled NO      To toggle enabled   disabled   If you have created the buttons in the Interface Builder and want to access them in code  you can take advantage of the fact that they are passed in as an argument to the IBAction calls   -  IBAction  triggerActionWithSender   id  sender    This can be bound to the button and you   ll get the button in the sender argument when the action is triggered  If that   s not enough  because you need to access the buttons somewhere else than in the actions   declare an outlet for the button    property retain  IBOutlet UIButton  someButton    Then it   s possible to bind the button in IB to the controller  the NIB loading code will set the property value when loading the interface

In Swift 3  you can simply change the title of a button by   button setTitle  Title   for   normal    and you disable the button by   button isEnabled   false    normal is the same as UIControlState normal because the type is inferred

If you want to change the title as a response to being tapped you can try this inside the IBAction method of the button in your view controller delegate  This toggles a voice chat on and off  Setting up the voice chat is not covered here   -  IBAction startChat  id sender   UIButton  chatButton    UIButton  sender  if   voiceChat active        UIAlertController  alert    UIAlertController alertControllerWithTitle   Voice Chat                                                                     message   Voice Chat will become live  Please be careful with feedback if your friend is nearby                                                               preferredStyle UIAlertControllerStyleAlert       UIAlertAction  defaultAction    UIAlertAction actionWithTitle   OK  style UIAlertActionStyleDefault                                                           handler   UIAlertAction   action            alert addAction defaultAction        self presentViewController alert animated YES completion nil        voiceChat start       voiceChat active   YES       chatButton setTitle   Stop Chat  forState UIControlStateNormal     else        voiceChat stop       UIAlertController  alert    UIAlertController alertControllerWithTitle   Voice Chat                                                                     message   Voice Chat is closed                                                              preferredStyle UIAlertControllerStyleAlert       UIAlertAction  defaultAction    UIAlertAction actionWithTitle   OK  style UIAlertActionStyleDefault                                                           handler   UIAlertAction   action             alert addAction defaultAction        self presentViewController alert animated YES completion nil       voiceChat active   NO       chatButton setTitle   Chat  forState UIControlStateNormal          voiceChat is specific to voice chat of course  but you can use your ow local boolean property to control the switch
