我发现了罗伯托发布的选项。buratti是最快的解决方案,这里是Swift:
let leftView = UIView(frame: CGRect(x: 0, y: 0, width: 10, height: textField.frame.size.height))
leftView.backgroundColor = textField.backgroundColor
textField.leftView = leftView
textField.leftViewMode = UITextField.ViewMode.always

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)
}
}
斯威夫特 3+
import UIKit
class TextField: UITextField {
let inset: CGFloat = 10
// placeholder position
override func textRect(forBounds: CGRect) -> CGRect {
return forBounds.insetBy(dx: self.inset , dy: self.inset)
}
// text position
override func editingRect(forBounds: CGRect) -> CGRect {
return forBounds.insetBy(dx: self.inset , dy: self.inset)
}
override func placeholderRect(forBounds: CGRect) -> CGRect {
return forBounds.insetBy(dx: self.inset, dy: self.inset)
}
}
Swift 4.2版本:
import UIKit
class InsetTextField: UITextField {
let inset: CGFloat = 10
override func textRect(forBounds bounds: CGRect) -> CGRect {
return bounds.insetBy(dx: inset, dy: inset)
}
override func editingRect(forBounds bounds: CGRect) -> CGRect {
return bounds.insetBy(dx: inset, dy: inset)
}
override func placeholderRect(forBounds bounds: CGRect) -> CGRect {
return bounds.insetBy(dx: inset, dy: inset)
}
}

let leftView = UIView(frame: CGRect(x: 0, y: 0, width: 10, height: textField.frame.size.height))
leftView.backgroundColor = textField.backgroundColor
textField.leftView = leftView
textField.leftViewMode = UITextField.ViewMode.always
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。
你可以通过使文本字段成为UITextField的子类并覆盖-textRectForBounds:方法来调整文本在文本字段中的位置。
