Adding and Removing a Member

Users can be added to groups and removed from groups.

Adding a member

A group owner can add additional members to their group with the addUser() method:

Swift:

// Instantiate a user.
let user2 = KiiUser(uri: "Set the URI of an existing user here")

// Add the user to the group.
group.add(user2)

do {
  // Save the group on the server.
  try group.saveSynchronous()
} catch let error as NSError {
  // Handle the error.
  return
}

// Instantiate a user.
let user2 = KiiUser(uri: "Set the URI of an existing user here")

// Add the user to the group.
group.add(user2)

// Save the group on the server.
group.save { (group : KiiGroup?, error : Error?) -> Void in
  if error != nil {
    // Handle the error.
    return
  }
}

Objective-C:

// Instantiate a user.
KiiUser *user2 = [KiiUser userWithURI:@"Set the URI of an existing user here"];

// Add the user to the group.
[group addUser:user2];

// Save the group on the server.
NSError *error;
[group saveSynchronous:&error];

if (error != nil) {
  // Handle the error.
  return;
}

// Instantiate a user.
KiiUser *user2 = [KiiUser userWithURI:@"Set the URI of an existing user here"];

// Add the user to the group.
[group addUser:user2];

// Save the group on the server.
[group saveWithBlock:^(KiiGroup *group, NSError *error) {
  if (error != nil) {
    // Handle the error.
    return;
  }
}];

Make sure to execute the save(_:) method to reflect the changes.

Removing a member

A group owner can remove existing members from their group with the removeUser() method:

Swift:

// Instantiate a user.
let user2 = KiiUser(uri: "Set the URI of an existing user here")

// Remove the user from the group.
group.remove(user2)

do {
  // Save the group on the server.
  try group.saveSynchronous()
} catch let error as NSError {
  // Handle the error.
  return
}

// Instantiate a user.
let user2 = KiiUser(uri: "Set the URI of an existing user here")

// Remove the user from the group.
group.remove(user2)

// Save the group on the server.
group.save { (group : KiiGroup?, error : Error?) -> Void in
  if error != nil {
    // Handle the error.
    return
  }
}

Objective-C:

// Instantiate a user.
KiiUser *user2 = [KiiUser userWithURI:@"Set the URI of an existing user here"];

// Remove the user from the group.
[group removeUser:user2];

// Save the group on the server.
NSError *error;
[group saveSynchronous:&error];

if (error != nil) {
  // Handle the error.
  return;
}

// Instantiate a user.
KiiUser *user2 = [KiiUser userWithURI:@"Set the URI of an existing user here"];

// Remove the user from the group.
[group removeUser:user2];

// Save the group on the server.
[group saveWithBlock:^(KiiGroup *group, NSError *error) {
  if (error != nil) {
    // Handle the error.
    return;
  }
}];
