问题:如何增加 UITextField 中插入符/光标的高度
到目前为止我尝试了什么:
我这样做了,问题解决了。
class BPTextField: UITextField {
override func caretRect(for position: UITextPosition) -> CGRect {
//CGRect rect = [super caretRectForPosition:position];
var rect = super.caretRect(for: position)
let h = self.frame.height - 5
let y_ = (self.frame.height - h)/2
rect.origin.y = y_
rect.size.height = h;
return rect;
}
}
但是,当我更改键盘语言(从英语-印度语到日语-假名语)并键入单个字符时,插入符号/光标在 TextField 中移到上侧。
请帮帮我

编辑
我正在使用 YYText
库,我正在将此 BPTextField
作为 NSAttributedStringAttachment
YYLabel
中
这里是 NSAttributedString,
let main = NSMutableAttributedString(string: text_)
main.yy_color = .darkGray
main.yy_font = questionFont
main.yy_lineSpacing = 5.0
main.yy_lineBreakMode = .byWordWrapping
//附件
let attachment = NSMutableAttributedString.yy_attachmentString(withContent: self.tf, contentMode: UIView.ContentMode.center, attachmentSize: self.tf.frame.size, alignTo: questionFont, alignment: YYTextVerticalAlignment.bottom)
attachment.yy_baselineOffset = -5.0
root.append(attachment)
//BP文本字段
self.tf = BPTextField(frame: CGRect(origin: CGPoint.init(x: 0, y: 13), size: CGSize(width: tfWidth.width + 7.5, height: tfWidth.height + 13.0)))
self.tf.borderStyle = UITextField.BorderStyle.none
self.tf.tag = 0
self.tf.font = questionFont
self.tf.autocorrectionType = UITextAutocorrectionType.no
self.tf.textColor = .darkGray
self.tf.setRoundedCorners(corners: UIRectCorner.allCorners, withRadius: 4.0)
// self.tf.setLeftPaddingPoints(5.0)
// self.tf.setRightPaddingPoints(0.0)
self.tf.backgroundColor = #colorLiteral(red: 0.9058823529, green: 0.9529411765, blue: 1, alpha: 1)
self.tf.tintColor = #colorLiteral(red: 0.2196078431, green: 0.6156862745, blue: 1, alpha: 1)
self.tf.returnKeyType = .done
self.tf.delegate = self
最佳答案
你可以如下计算origin y
,
override func caretRect(for position: UITextPosition) -> CGRect {
var rect = super.caretRect(for: position)
let size = CGSize(width: rect.size.width, height: self.frame.height - 5)
// Calculating center y
let y = rect.origin.y - (size.height - rect.size.height)/2
rect = CGRect(origin: CGPoint(x: rect.origin.x, y: y), size: size)
return rect
}
