Get string value from select UISegmentedControl segment

Question

I've created a SignUp page (ViewController) and on gender selection I'm using a UISegmentedControl for "male", "female", "indifferent". But how can I get the value from the UISegmentedControl and put in a dictionary? I'm using a custom Dictionary<String, String> = [:] for signup but the UISegmentedControl is not a string (obviously) and I get the error:

Cannot assign value of type 'UISegmentedControl' to type 'String'

How can I convert the result of UISegmentedControl to receive those values?

Answer 1

You get the segmentedControl in your code, but not it's selectedSegmentIndex property. Then after receiving the selectedSegmentIndex, you should get the title for that index from control. Update your code with following:

if let gender = self.generoSegmentControl {

Either change it to:

let genderIndex = self.generoSegmentControl.selectedSegmentIndex
if let gender = self.generoSegmentControl.titleForSegment(at: genderIndex) {

}

OR change the way you update dictionary:

let index = gender.selectedSegmentIndex
if let segmentTitle = gender.titleForSegment(at: index) {
    user["nome"] = name
    user["email"] =  email
    user["nascimento"] =  birthday
    user["instagram"] =  instagramuser
    user["genero"] = segmentTitle
}
