Create space at the beginning of a UITextField
IosSwiftCocoa TouchUitextfieldIos Problem Overview
I want to leave a bit of space at the beginning of a UITextField, just like here: https://stackoverflow.com/questions/5674655/uitextfield-align-left-margin
But I don't know how to do that with Swift.

This is what I am using right now:
Swift 4.2
class TextField: UITextField {
let padding = UIEdgeInsets(top: 0, left: 5, bottom: 0, right: 5)
override open func textRect(forBounds bounds: CGRect) -> CGRect {
return bounds.inset(by: padding)
}
override open func placeholderRect(forBounds bounds: CGRect) -> CGRect {
return bounds.inset(by: padding)
}
override open func editingRect(forBounds bounds: CGRect) -> CGRect {
return bounds.inset(by: padding)
}
}
Swift 4
class TextField: UITextField {
let padding = UIEdgeInsets(top: 0, left: 5, bottom: 0, right: 5)
override open func textRect(forBounds bounds: CGRect) -> CGRect {
return UIEdgeInsetsInsetRect(bounds, padding)
}
override open func placeholderRect(forBounds bounds: CGRect) -> CGRect {
return UIEdgeInsetsInsetRect(bounds, padding)
}
override open func editingRect(forBounds bounds: CGRect) -> CGRect {
return UIEdgeInsetsInsetRect(bounds, padding)
}
}
Swift 3:
class TextField: UITextField {
let padding = UIEdgeInsets(top: 0, left: 5, bottom: 0, right: 5)
override func textRect(forBounds bounds: CGRect) -> CGRect {
return UIEdgeInsetsInsetRect(bounds, padding)
}
override func placeholderRect(forBounds bounds: CGRect) -> CGRect {
return UIEdgeInsetsInsetRect(bounds, padding)
}
override func editingRect(forBounds bounds: CGRect) -> CGRect {
return UIEdgeInsetsInsetRect(bounds, padding)
}
}
I never set a other padding but you can tweak. This class doesn't take care of the rightView and leftView on the textfield. If you want that to be handle correctly you can use something like (example in objc and I only needed the rightView:
- (CGRect)textRectForBounds:(CGRect)bounds {
CGRect paddedRect = UIEdgeInsetsInsetRect(bounds, self.insets);
if (self.rightViewMode == UITextFieldViewModeAlways || self.rightViewMode == UITextFieldViewModeUnlessEditing) {
return [self adjustRectWithWidthRightView:paddedRect];
}
return paddedRect;
}
- (CGRect)placeholderRectForBounds:(CGRect)bounds {
CGRect paddedRect = UIEdgeInsetsInsetRect(bounds, self.insets);
if (self.rightViewMode == UITextFieldViewModeAlways || self.rightViewMode == UITextFieldViewModeUnlessEditing) {
return [self adjustRectWithWidthRightView:paddedRect];
}
return paddedRect;
}
- (CGRect)editingRectForBounds:(CGRect)bounds {
CGRect paddedRect = UIEdgeInsetsInsetRect(bounds, self.insets);
if (self.rightViewMode == UITextFieldViewModeAlways || self.rightViewMode == UITextFieldViewModeWhileEditing) {
return [self adjustRectWithWidthRightView:paddedRect];
}
return paddedRect;
}
- (CGRect)adjustRectWithWidthRightView:(CGRect)bounds {
CGRect paddedRect = bounds;
paddedRect.size.width -= CGRectGetWidth(self.rightView.frame);
return paddedRect;
}
Solution 2 - Ios
If you use an extension, there is no need to subclass UITextField and the new functionality will be made available to any UITextField in your app:
extension UITextField {
func setLeftPaddingPoints(_ amount:CGFloat){
let paddingView = UIView(frame: CGRect(x: 0, y: 0, width: amount, height: self.frame.size.height))
self.leftView = paddingView
self.leftViewMode = .always
}
func setRightPaddingPoints(_ amount:CGFloat) {
let paddingView = UIView(frame: CGRect(x: 0, y: 0, width: amount, height: self.frame.size.height))
self.rightView = paddingView
self.rightViewMode = .always
}
}
When I need to set the padding of a text field anywhere in my application, I simply do the following:
textField.setLeftPaddingPoints(10)
textField.setRightPaddingPoints(10)
Using Swift extensions, the functionality is added to the UITextField directly without subclassing.
Hope this helps!

X, Y , Z are your desired values
textField.layer.sublayerTransform = CATransform3DMakeTranslation(x, y, z)
Solution 4 - Ios
Such margin can be achieved by setting leftView / rightView to UITextField.
Updated For Swift 4
// Create a padding view for padding on left
textField.leftView = UIView(frame: CGRect(x: 0, y: 0, width: 15, height: textField.frame.height))
textField.leftViewMode = .always
// Create a padding view for padding on right
textField.rightView = UIView(frame: CGRect(x: 0, y: 0, width: 15, height: textField.frame.height))
textField.rightViewMode = .always
I just added/placed an UIView to left and right side of the textfield. So now the typing will start after the view.
Thanks
Hope this helped...

Swift 4, Xcode 9
I like Pheepster's answer, but how about we do it all from the extension, without requiring VC code or any subclassing:
import UIKit
@IBDesignable
extension UITextField {
@IBInspectable var paddingLeftCustom: CGFloat {
get {
return leftView!.frame.size.width
}
set {
let paddingView = UIView(frame: CGRect(x: 0, y: 0, width: newValue, height: frame.size.height))
leftView = paddingView
leftViewMode = .always
}
}
@IBInspectable var paddingRightCustom: CGFloat {
get {
return rightView!.frame.size.width
}
set {
let paddingView = UIView(frame: CGRect(x: 0, y: 0, width: newValue, height: frame.size.height))
rightView = paddingView
rightViewMode = .always
}
}
}
Solution 6 - Ios
Use my extension Swift 5 tested:
extension UITextField {
enum PaddingSpace {
case left(CGFloat)
case right(CGFloat)
case equalSpacing(CGFloat)
}
func addPadding(padding: PaddingSpace) {
self.leftViewMode = .always
self.layer.masksToBounds = true
switch padding {
case .left(let spacing):
let leftPaddingView = UIView(frame: CGRect(x: 0, y: 0, width: spacing, height: self.frame.height))
self.leftView = leftPaddingView
self.leftViewMode = .always
case .right(let spacing):
let rightPaddingView = UIView(frame: CGRect(x: 0, y: 0, width: spacing, height: self.frame.height))
self.rightView = rightPaddingView
self.rightViewMode = .always
case .equalSpacing(let spacing):
let equalPaddingView = UIView(frame: CGRect(x: 0, y: 0, width: spacing, height: self.frame.height))
// left
self.leftView = equalPaddingView
self.leftViewMode = .always
// right
self.rightView = equalPaddingView
self.rightViewMode = .always
}
}
}
How to use
// equal padding
yourTextField.addPadding(padding: .equalSpacing(10))
// padding right
yourTextField.addPadding(padding: .right(10))
// padding left
yourTextField.addPadding(padding: .left(10))
Solution 7 - Ios
in Swift 4.2 and Xcode 10
Initially my text field is like this.
After adding padding in left side my text field is...
//Code for left padding
textFieldName.leftView = UIView(frame: CGRect(x: 0, y: 0, width: 10, height: textFieldName.frame.height))
textFieldName.leftViewMode = .always
Like this we can create right side also.(textFieldName.rightViewMode = .always)
If you want SharedInstance type code(Write once use every ware) see the below code.
//This is my shared class
import UIKit
class SharedClass: NSObject {
static let sharedInstance = SharedClass()
//This is my padding function.
func textFieldLeftPadding(textFieldName: UITextField) {
// Create a padding view
textFieldName.leftView = UIView(frame: CGRect(x: 0, y: 0, width: 3, height: textFieldName.frame.height))
textFieldName.leftViewMode = .always//For left side padding
textFieldName.rightViewMode = .always//For right side padding
}
private override init() {
}
}
Now call this function like this.
//This single line is enough
SharedClass.sharedInstance.textFieldLeftPadding(textFieldName:yourTF)

Simple swift 3 solution - add code to viewDidLoad:
let indentView = UIView(frame: CGRect(x: 0, y: 0, width: 10, height: 20))
textField.leftView = indentView
textField.leftViewMode = .always
No need for ridiculously long code

Here is Haagenti's answer updated to Swift 4.2:
class PaddedTextField: UITextField {
func getPadding(plusExtraFor clearButtonMode: ViewMode) -> UIEdgeInsets {
var padding = UIEdgeInsets(top: 11, left: 16, bottom: 11, right: 16)
// Add additional padding on the right side when showing the clear button
if self.clearButtonMode == .always || self.clearButtonMode == clearButtonMode {
padding.right = 28
}
return padding
}
override open func textRect(forBounds bounds: CGRect) -> CGRect {
let padding = getPadding(plusExtraFor: .unlessEditing)
return bounds.inset(by: padding)
}
override open func placeholderRect(forBounds bounds: CGRect) -> CGRect {
let padding = getPadding(plusExtraFor: .unlessEditing)
return bounds.inset(by: padding)
}
override open func editingRect(forBounds bounds: CGRect) -> CGRect {
let padding = getPadding(plusExtraFor: .whileEditing)
return bounds.inset(by: padding)
}
}

Edit: Account for clear button.

This one line of code saved me:
For Xamarin.iOS:
textField.Layer.SublayerTransform = CATransform3D.MakeTranslation(5, 0, 0);
For Swift:
textField.layer.sublayerTransform = CATransform3DMakeTranslation(5, 0, 0);

Subclassing UITextField is the way to go. Open a playground and add the following code:
class MyTextField : UITextField {
var leftTextMargin : CGFloat = 0.0
override func textRectForBounds(bounds: CGRect) -> CGRect {
var newBounds = bounds
newBounds.origin.x += leftTextMargin
return newBounds
}
override func editingRectForBounds(bounds: CGRect) -> CGRect {
var newBounds = bounds
newBounds.origin.x += leftTextMargin
return newBounds
}
}
let tf = MyTextField(frame: CGRect(x: 0, y: 0, width: 100, height: 44))
tf.text = "HELLO"
tf.leftTextMargin = 25
tf.setNeedsLayout()
tf.layoutIfNeeded()
Solution 13 - Ios
Create UIView with required padding space and add it to textfield.leftView member and set textfield.leftViewMode member to UITextFieldViewMode.Always
// For example if you have textfield named title
@IBOutlet weak var title: UITextField!
// Create UIView
let paddingView : UIView = UIView(frame: CGRectMake(0, 0, 5, 20))
//Change your required space instaed of 5.
title.leftView = paddingView
title.leftViewMode = UITextFieldViewMode.Always

Easy way: to do this by extending UITextField
extension UITextField {
func setPadding(left: CGFloat? = nil, right: CGFloat? = nil){
if let left = left {
let paddingView = UIView(frame: CGRect(x: 0, y: 0, width: left, height: self.frame.size.height))
self.leftView = paddingView
self.leftViewMode = .always
}
if let right = right {
let paddingView = UIView(frame: CGRect(x: 0, y: 0, width: right, height: self.frame.size.height))
self.rightView = paddingView
self.rightViewMode = .always
}
}
}
Then you can set padding to any edge this way:
textField.setPadding(left: 5, right: 5)
Solution 15 - Ios
Put this code in your viewDidLoad():
textField.delegate = self
let paddingView = UIView(frame: CGRect(x: 0, y: 0, width: 20, height: self.textField.frame.height))
textField.leftView = paddingView
textField.leftViewMode = UITextFieldViewMode.always
It works for me :)

In Swift 3. You may use custom UITextField with indent that is set in its constructor. Don't need for extra declaration in a controller.
class CustomTextField : UITextField {
private let indentView = UIView(frame: CGRect(x: 0, y:0, width: 10, height: 10))
required init?(coder aDecoder: NSCoder) {
super.init(coder: aDecoder)
self.leftView = indentView
self.leftViewMode = .always
}
}

I prefer to use IBDesignable class and IBInspectable properties to allow me to set the padding via Xcode storyboards and keep it reusable. I've also updated the code to work in Swift 4.
import Foundation
import UIKit
@IBDesignable
class PaddableTextField: UITextField {
var padding = UIEdgeInsets(top: 0.0, left: 0.0, bottom: 0.0, right: 0.0)
@IBInspectable var left: CGFloat = 0 {
didSet {
adjustPadding()
}
}
@IBInspectable var right: CGFloat = 0 {
didSet {
adjustPadding()
}
}
@IBInspectable var top: CGFloat = 0 {
didSet {
adjustPadding()
}
}
@IBInspectable var bottom: CGFloat = 0 {
didSet {
adjustPadding()
}
}
func adjustPadding() {
padding = UIEdgeInsets(top: top, left: left, bottom: bottom, right: right)
}
override func prepareForInterfaceBuilder() {
super.prepareForInterfaceBuilder()
}
override func textRect(forBounds bounds: CGRect) -> CGRect {
return bounds.inset(by: UIEdgeInsets(top: top, left: left, bottom: bottom, right: right))
}
override func placeholderRect(forBounds bounds: CGRect) -> CGRect {
return bounds.inset(by: UIEdgeInsets(top: top, left: left, bottom: bottom, right: right))
}
override func editingRect(forBounds bounds: CGRect) -> CGRect {
return bounds.inset(by: UIEdgeInsets(top: top, left: left, bottom: bottom, right: right))
}
}

In most cases you can regard this as a technicality but all the examples don't get the difference between frame and bounds right. When referencing the view's height in a subview, use bounds – otherwise you may run into trouble once some transform is applied to the parent.
See the updated code below (based on Pheepster's answer).
extension UITextField {
func setLeftPadding(_ amount: CGFloat = 10) {
let paddingView = UIView(frame: CGRect(x: 0, y: 0, width: amount, height: self.bounds.size.height))
self.leftView = paddingView
self.leftViewMode = .always
}
func setRightPadding(_ amount: CGFloat = 10) {
let paddingView = UIView(frame: CGRect(x: 0, y: 0, width: amount, height: self.bounds.size.height))
self.rightView = paddingView
self.rightViewMode = .always
}
}
