UITextField의 시작 부분에 공간을 만듭니다.

UITextField의 시작 부분에 다음과 같이 약간의 공간을 남기고 싶습니다. UITextField에 왼쪽 여백 추가

그러나 Swift로 어떻게 해야하는지 모르겠습니다.

이것은 내가 지금 사용하고있는 것입니다 :

스위프트 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)
    }
}

스위프트 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)
    }
}

스위프트 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)
    }
}

다른 패딩을 설정하지는 않지만 조정할 수는 있습니다. 이 클래스는 텍스트 필드에서 rightView 및 leftView를 처리하지 않습니다. 올바르게 처리하려면 (objc의 예와 같이 rightView 만 필요했습니다)

- (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;
}

확장을 사용하는 경우 UITextField를 서브 클래 싱 할 필요가 없으며 앱의 모든 UITextField에서 새 기능을 사용할 수 있습니다.

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
    }
}

응용 프로그램의 어느 곳에서나 텍스트 필드의 패딩을 설정해야 할 때 간단히 다음을 수행하십시오.

    textField.setLeftPaddingPoints(10)
    textField.setRightPaddingPoints(10)

Swift 확장을 사용하면 서브 클래 싱없이 UITextField에 기능이 직접 추가됩니다.

도움이 되었기를 바랍니다!

X, Y, Z는 원하는 값입니다

textField.layer.sublayerTransform = CATransform3DMakeTranslation(x, y, z)

leftView/ rightView로 설정하면 이러한 마진을 얻을 수 있습니다.UITextField .

스위프트 4 업데이트

// 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

방금 추가 / 배치 UIView 텍스트 필드의 왼쪽과 오른쪽을 했습니다. 이제보기 후에 타이핑이 시작됩니다.

감사

이것이 도움이 되었기를 바랍니다 ...

스위프트 4, Xcode 9

나는 좋아한다 Pheepster의 답변을 하지만 VC 코드 또는 하위 클래스를 요구하지 않고 확장 프로그램에서 모두 수행하는 방법은 ?

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     
        }
    }
}

에서 스위프트 4.2 엑스 코드 (10)

처음에 내 텍스트 필드는 다음과 같습니다.

왼쪽에 패딩을 추가하면 내 텍스트 필드는 ...

//Code for left padding 
textFieldName.leftView = UIView(frame: CGRect(x: 0, y: 0, width: 10, height: textFieldName.frame.height))
textFieldName.leftViewMode = .always

이와 같이 오른쪽도 만들 수 있습니다. (textFieldName.rightViewMode = .always)

SharedInstance 유형 코드를 원하면 (모든웨어를 한 번 작성하십시오) 아래 코드를 참조하십시오.

//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() {

    }
}

이제이 함수를 이렇게 호출하십시오.

//This single line is enough
SharedClass.sharedInstance.textFieldLeftPadding(textFieldName:yourTF)

간단한 신속한 3 솔루션-viewDidLoad에 코드 추가 :

let indentView = UIView(frame: CGRect(x: 0, y: 0, width: 10, height: 20))
textField.leftView = indentView
textField.leftViewMode = .always

엄청나게 긴 코드 필요 없음

내 확장 Swift 5를 사용하여 테스트했습니다.

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
    }
}
}

사용하는 방법

// equal padding
yourTextField.addPadding(padding: .equalSpacing(10)) 

// padding right 
yourTextField.addPadding(padding: .right(10))

// padding left
yourTextField.addPadding(padding: .left(10)) 

Swift 5에서 UITextField의 패딩 뷰를 만들려면

func txtPaddingVw(txt:UITextField) {
    let paddingView = UIView(frame: CGRect(x: 0, y: 0, width: 5, height: 5))
    txt.leftViewMode = .always
    txt.leftView = paddingView
}

UITextField를 서브 클래 싱하는 것이 좋습니다. 놀이터를 열고 다음 코드를 추가하십시오.

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()

다음은 Swift 4.2로 업데이트 된 Haagenti의 답변입니다 .

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)
    }

}

편집 : 지우기 버튼 계정.

필요한 패딩 공간으로 UIView를 만들고 textfield.leftView 멤버에 추가하고 textfield.leftViewMode 멤버를 UITextFieldViewMode.Always로 설정하십시오.

// 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

이 코드를 당신의 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

그것은 나를 위해 작동합니다 :)

이 한 줄의 코드로 나를 구했습니다.

Xamarin.iOS의 경우 :

textField.Layer.SublayerTransform = CATransform3D.MakeTranslation(5, 0, 0);

스위프트

textField.layer.sublayerTransform = CATransform3DMakeTranslation(5, 0, 0);

Swift 3의 ScareCrow 답변

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)
}

Swift 3에서는 생성자에 설정된 들여 쓰기와 함께 사용자 정의 UITextField를 사용할 수 있습니다. 컨트롤러에서 추가 선언이 필요하지 않습니다.

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 
        }
}

쉬운 방법 : UITextField를 확장 하여이 작업을 수행하십시오.

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
       }
   }

}

그런 다음이 방법으로 패딩을 모든 가장자리에 설정할 수 있습니다.

textField.setPadding(left: 5, right: 5)

IBDesignable클래스와 IBInspectable속성을 사용하여 Xcode 스토리 보드를 통해 패딩을 설정하고 재사용 가능하게 유지 하는 것을 선호합니다 . 또한 Swift 4에서 작동하도록 코드를 업데이트했습니다.

    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))
    }
}

Swift 5에서 UITextField 확장

@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
