无法将图像作为 NSTextAttachment 添加到 UITextField
Cant add image as NSTextAttachment to UITextField
我正在尝试将图像添加为 NSTextAttachment
到 UITextField
,但我得到的只是 ,
自定义代码 UITextField
:
let myAttachment = NSTextAttachment()
myAttachment.image = myImage
myAttachment.bounds = CGRect(origin: .zero, size: myImage.size)
let myImageString = NSAttributedString(attachment: myAttachment)
let updatedText = NSMutableAttributedString()
updatedText.append(myImageString)
let myTextString = NSAttributedString(string: ", " + (self.text ?? ""))
updatedText.append(myTextString)
self.attributedText = updatedText
你是对的,NSTextAttachment
没有出现在 UITextField
中,我不确定这是一个错误还是 UITextField
的设计,我会提交雷达并更新此处回复:
同时,如果您可以将 UI 元素更改为 UILabel
和 UITextView
,则以下工作文件:
let attachment = NSTextAttachment()
attachment.image = myImage
attachment.bounds = CGRect(origin: .zero, size: myImage.size)
let attributedStr = NSMutableAttributedString(string: self.text ?? "")
attributedStr.insert(NSAttributedString(attachment: attachment), at: 0)
UITextField
不允许 NSTextAttachment
但 UILabel
允许 NSTextAttachment
。
例如:
let attachment = NSTextAttachment()
let imageTest = UIImage(named:"user.png")
attachment.image = imageTest
let myString = NSMutableAttributedString(string: "My text ")
let myStringWithImage = NSMutableAttributedString(attributedString: NSAttributedString(attachment: attachment))
myStringWithImage.append(myString)
myTextField.attributedText = myStringWithImage
myLabel.attributedText = myStringWithImage
这个苹果中没有答案thread。根据我的想法,我们可以在文本字段中输入表情符号,但不能在文本附件中输入。在文本字段中,我们为用户提供了输入文本的灵活性。
可以使用UITextField
的leftView
来显示图片。
