居中的 UITextField 文本在编辑时意外移动

Question

我在 UICollectionView 单元格中有一个居中的 UITextField，但文本在编辑时奇怪地向右移动。是什么导致了问题？

let textLabel: UITextField = {
        let label = UITextField()
        label.textAlignment = .center
        label.adjustsFontSizeToFitWidth = true
        label.minimumFontSize = 12
        return label
    }()

addSubview(textLabel)
textLabel.leadingAnchor.constraint(equalTo: self.leadingAnchor, constant: 15).isActive = true
textLabel.bottomAnchor.constraint(equalTo: self.bottomAnchor).isActive = true
textLabel.topAnchor.constraint(equalTo: self.topAnchor).isActive = true
textLabel.trailingAnchor.constraint(equalTo: self.trailingAnchor, constant: -15).isActive = true

这是问题的屏幕截图：

更新：原来 UITextfield 的高度太大了，我降低了它的高度，现在一切正常。感谢您的帮助！

textLabel.leadingAnchor.constraint(equalTo: self.leadingAnchor, constant: 15).isActive = true
textLabel.heightAnchor.constraint(equalToConstant: 50).isActive = true
textLabel.centerYAnchor.constraint(equalTo: self.centerYAnchor).isActive = true
textLabel.trailingAnchor.constraint(equalTo: self.trailingAnchor, constant: -15).isActive = true
