Sketch a bit in Swift I find that I do not know which is the control to make the following type of model 
so far I have
My question would be how to imitate the image above
Add as you told me a view of 1 height but the view is far below
it is the first of all the one that the bottom is like in white
but the line appears at the bottom
Apart from this I get the color of the edittext some way to remove it?
It is simple to add a subview to act as a line. Here is a guide example:
Swift 4
let lineView = UIView(frame: CGRect(x: 0, y: 100, width: 320, height: 1.0))
lineView.layer.borderWidth = 1.0
lineView.layer.borderColor = UIColor.black.cgColor
self.view.addSubview(lineView)
Objective C
UIView * lineview = [[UIView alloc] initWithFrame:CGRectMake(0, 100,320,1)];
lineview.layer.borderColor = [UIColor blackColor].CGColor;
lineview.layer.borderWidth = 1.0;
[self.view addSubview:lineview];
Or you can check this link to add CALayer or draw a view
how to draw a line programmatically from a view controller? (Info in English).
Use this UIView extension
public enum UIButtonBorderSide {
case Top, Bottom, Left, Right, All
}
extension UIView {
public func addBorder(side: UIButtonBorderSide, color: UIColor, width: CGFloat) {
let border = CALayer()
border.name = "border"
border.backgroundColor = color.cgColor
switch side {
case .Top:
border.frame = CGRect(x: 0, y: 0, width: frame.size.width, height: width)
self.layer.addSublayer(border)
case .Bottom:
border.frame = CGRect(x: 0, y: self.frame.size.height - width, width: self.frame.size.width, height: width)
self.layer.addSublayer(border)
case .Left:
border.frame = CGRect(x: 0, y: 0, width: width, height: self.frame.size.height)
self.layer.addSublayer(border)
case .Right:
border.frame = CGRect(x: self.frame.size.width - width, y: 0, width: width, height: self.frame.size.height)
self.layer.addSublayer(border)
case .All:
let topBorder = CALayer()
let bottomBorder = CALayer()
let rightBorder = CALayer()
let leftBorder = CALayer()
topBorder.frame = CGRect(x: 0, y: 0, width: frame.size.width, height: width)
topBorder.backgroundColor = color.cgColor
bottomBorder.frame = CGRect(x: 0, y: self.frame.size.height - width, width: self.frame.size.width, height: width)
bottomBorder.backgroundColor = color.cgColor
leftBorder.frame = CGRect(x: 0, y: 0, width: width, height: self.frame.size.height)
leftBorder.backgroundColor = color.cgColor
rightBorder.frame = CGRect(x: self.frame.size.width - width, y: 0, width: width, height: self.frame.size.height)
rightBorder.backgroundColor = color.cgColor
self.layer.addSublayer(topBorder)
self.layer.addSublayer(bottomBorder)
self.layer.addSublayer(leftBorder)
self.layer.addSublayer(rightBorder)
}
}
}
And you use it this way
miTextField.addBorder(side: .Bottom, color: UIColor.blue, width: 2.0)
