I want to make a search field in my app, and I was wondering if it is possible to make it invisible to begin with and then make it appear with the click of a button, like with the magnifying glass in the video below.
I have tried making the width of a UITextField 0 to begin with and then make a button make the width larger, but I am doing something wrong, and I can not figure out what. Maybe you could make an example in a blank project and show/link the code?
I hope you can help :)

Function for expand the SearchTextField
func setTextField(setExpand:Bool = false){
self.txtfldSearch.delegate = self
self.txtfldSearch.borderStyle = UITextField.BorderStyle.none
self.txtfldSearch.translatesAutoresizingMaskIntoConstraints = true
let bottomLine = CALayer()
bottomLine.backgroundColor = UIColor.red.cgColor
UIView.animate(withDuration: 0.5) {
if setExpand{
self.txtfldSearch.frame = CGRect(x:
self.viewContainer.frame.origin.x + 8, y:
self.txtfldSearch.frame.origin.y, width:
(self.btnSearch.frame.origin.x -
(self.viewContainer.frame.origin.x + 16)),
height: self.txtfldSearch.frame.size.height)
bottomLine.frame = CGRect(x: 0.0, y:
self.txtfldSearch.frame.size.height-2, width:
self.txtfldSearch.frame.size.width, height: 2.0)
}
else{
self.txtfldSearch.frame = CGRect(x:
self.btnSearch.frame.origin.x - 8,
y: self.txtfldSearch.frame.origin.y, width: 0,
height:self.txtfldSearch.frame.size.height)
bottomLine.frame = CGRect(x: 0.0, y:
self.txtfldSearch.frame.size.height-2, width:
self.txtfldSearch.frame.size.width, height: 2.0)
}
}
self.txtfldSearch.layer.addSublayer(bottomLine)
}
Use of Code For Expanding pass true and other case pass false
self.setTextField(setExpand: true)

UIView.animate(withDuration: 0.3, delay: 0, options: .curveEaseInOut, animations: {
//change view width
}) { (completed) in
//you can use completion or you can delete I am using it like that
self.searchTextview.becomeFirstResponder()
}
I am using this for my view. You can change for your need. Change constraints or width with animation
