I'm trying to add icon in textfield. This is how my UI looks now with code below
Im expecting my UI should look similar to this image
// creating view (holderView) to hold icon image(image) and add view to textField (txtEmail)
let holderView = UIView(frame: CGRect(x:0, y:0, width: 40, height: 40))
let imageView = UIImageView(frame: CGRect(x: 0, y: 0, width: 20, height: 20))
let image = UIImage(named: "ic_lock_48pt")
imageView.image = image
holderView.backgroundColor = UIColor.lightGray
holderView.addSubview(imageView)
imageView.center = CGPoint(x: holderView.frame.size.width / 2, y: holderView.frame.size.height / 2)
txtEmail.leftView = holderView
( If im doing long process to fix this please let me know )
so I wanted to add constraints programatically to fix and below is the code
holderView.translatesAutoresizingMaskIntoConstraints = false
let leadingConstraint = NSLayoutConstraint(item: holderView, attribute: .leading, relatedBy: .equal, toItem: emailView, attribute: .leading, multiplier: 1, constant: 0)
let trailingConstraint = NSLayoutConstraint(item: holderView, attribute: .trailing, relatedBy: .equal, toItem: emailView, attribute: .trailing, multiplier: 0.12, constant: 0)
let topConstraint = NSLayoutConstraint(item: holderView, attribute: .top, relatedBy: .equal, toItem: emailView, attribute: .top, multiplier: 1, constant: 0)
let bottomConstraint = NSLayoutConstraint(item: holderView, attribute: .bottom, relatedBy: .equal, toItem: emailView, attribute: .bottom, multiplier: 1, constant: 0)
//I have txtEmail in another view (emailView) //Error while running any of two lines of code below
emailView.addConstraints([leadingConstraint, trailingConstraint, topConstraint, bottomConstraint]) //or
txtEmail.addConstraints([leadingConstraint, trailingConstraint, topConstraint, bottomConstraint])
Kindly suugest me how to fix this
Try his code:
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
textfield.leftViewMode = UITextFieldViewMode.always
let imageView = UIImageView(frame: CGRect(x: -1, y: 0, width: 30, height: 40))
let image = UIImage(named: "q.png")
imageView.backgroundColor = UIColor(white: 0.7, alpha: 0.6)
imageView.image = image
textfield.leftView = imageView
textfield.layer.borderColor = UIColor(white: 0.7, alpha: 0.6).cgColor
textfield.layer.borderWidth = 2
imageView.layer.borderColor = UIColor(white: 0.7, alpha: 0.6).cgColor
imageView.layer.borderWidth = 2
textfield.layer.cornerRadius = 5
textfield.layer.masksToBounds = true
}
Note: You have to create an icon image similar to below image to achieve the effect.Its all about creating an icon and place it in a right position.hope this helps..
