我做到了:

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

当然记得导入QuartzCore并将框架添加到您的项目中。

 class TextField: UITextField {

    let inset: CGFloat = 8

    // placeholder position
    override func textRect(forBounds bounds: CGRect) -> CGRect {
        return bounds.insetBy(dx: inset, dy: inset)
    }

    // text position
    override func editingRect(forBounds bounds: CGRect) -> CGRect {
        return bounds.insetBy(dx: inset, dy: inset)
    }
}

我在IB中做了这个，我在textView后面创建了一个UIView，它有点长。与textField背景颜色设置为清除。

下面是一个全面的Swift答案，包括一个leftView(自定义图标)和一个自定义清除按钮，两者都设置在界面生成器中，具有可定制的insets。

import UIKit

@IBDesignable
class InsetTextField: UITextField {
@IBInspectable var leftInset:CGFloat = 0
@IBInspectable var rightInset:CGFloat = 0
@IBInspectable var icon:UIImage? { didSet {
    let imageView = UIImageView(frame: CGRect(x: 0, y: 0, width: 16, height: 16))
    imageView.image = icon
    self.leftView = imageView
    self.leftViewMode = .Always
} }

@IBInspectable var clearButton:UIImage? { didSet {
    let button = UIButton(type: .Custom)
    button.setImage(clearButton, forState: .Normal)
    button.addTarget(self, action: "clear", forControlEvents: UIControlEvents.TouchUpInside)
    button.frame = CGRect(x: 0, y: 0, width: 18, height: 18)
    self.rightView = button
    self.rightViewMode = .WhileEditing
} }

func clear() {
    self.text = ""
}

override func leftViewRectForBounds(bounds: CGRect) -> CGRect {
    var height:CGFloat = 0
    var width:CGFloat = 0
    if let leftView = self.leftView {
        height = leftView.bounds.height
        width = leftView.bounds.width
    }

    return CGRect(x: leftInset, y: bounds.height/2 - height/2, width: width, height: height)
}

override func rightViewRectForBounds(bounds: CGRect) -> CGRect {
    var height:CGFloat = 0
    var width:CGFloat = 0
    if let rightView = self.rightView {
        height = rightView.bounds.height
        width = rightView.bounds.width
    }

    return CGRect(x: bounds.width - width - rightInset, y: bounds.height/2 - height/2, width: width, height: height)
}

}

我想我可以提供一个快速解决方案

import UIKit

class TextField: UITextField {
    let inset: CGFloat = 10

    // placeholder position
    override func textRectForBounds(bounds: CGRect) -> CGRect {
        return CGRectInset(bounds , inset , inset)
    }

    // text position
    override func editingRectForBounds(bounds: CGRect) -> CGRect {
        return CGRectInset(bounds , inset , inset)
    }

    override func placeholderRectForBounds(bounds: CGRect) -> CGRect {
        return CGRectInset(bounds, inset, inset) 
    }
}
