[英]Change Width of UITextfield Input
有没有办法更改我的UITextield的输入大小,使其不与我的“ vergessen”按钮重叠?
Textfield是一个简单的TextfieldView,宽度为315。我添加了“ Vergessen?”。 以编程方式按下下面的代码。
func createForgetButton () {
let button = UIButton(type: .system)
button.setTitle("Vergessen?", for: .normal)
button.addTarget(self, action: #selector(self.vergessenTapped(_:)), for: .touchUpInside)
button.titleLabel?.font = UIFont(name: "Avenir Next", size: 19.0)
passwordTextField.rightView = button
passwordTextField.rightViewMode = .unlessEditing
}
使用以下自定义类的字段。 然后,更新IB或代码中的.rightPadding
字段,以匹配右侧按钮的宽度。
/**

@IBDesignable public class CustomTextField: UITextField {
/// the left padding
@IBInspectable public var leftPadding: CGFloat = 0 { didSet { self.setNeedsLayout() } }
/// the right padding
@IBInspectable public var rightPadding: CGFloat = 0 { didSet { self.setNeedsLayout() } }
/// Text rectangle
///
/// - Parameter bounds: the bounds
/// - Returns: the rectangle
override public func textRect(forBounds bounds: CGRect) -> CGRect {
let originalRect: CGRect = super.editingRect(forBounds: bounds)
return CGRect(x: originalRect.origin.x + leftPadding, y: originalRect.origin.y, width: originalRect.size.width - leftPadding - rightPadding, height: originalRect.size.height)
}
/// Editing rectangle
///
/// - Parameter bounds: the bounds
/// - Returns: the rectangle
override public func editingRect(forBounds bounds: CGRect) -> CGRect {
let originalRect: CGRect = super.editingRect(forBounds: bounds)
return CGRect(x: originalRect.origin.x + leftPadding, y: originalRect.origin.y, width: originalRect.size.width - leftPadding - rightPadding, height: originalRect.size.height)
}
}
