大佬教程收集整理的这篇文章主要介绍了ios – NSTextAttachment图像未在NSTextView中显示(但在UITextView中)?,大佬教程大佬觉得挺不错的,现在分享给大家,也给大家做个参考。
NSTextAttachment的图像根本不显示.但是,它似乎仍然设置正确.因为复制NSTextView的内容并将其粘贴回例如TextEdit.app,粘贴的文本正确包含图像.
这是一个重现这个问题的最小游乐场:
import Cocoa let img = NSImage(named: "checked") let textView = NSTextView(frame: NsmakeRect(0,254,64)) let attrstr = NSMutableAttributedString(String: "Test") let attch = NSTextAttachment() attch.image = img attrstr.appendAttributedString(NSAttributedString(attachment: attch)) textView.textStorage!.setAttributedString(attrstr) textView
预期产量:
对于iOS,所以使用UIKit而不是Cocoa,它可以很好地工作:
import UIKit let img = UIImage(named: "checked") let textView = UITextView(frame: CGRectMake(0.0,0.0,200.0,44.0)) let attrstr = NSMutableAttributedString(String: "Test") let attch = NSTextAttachment() attch.image = img attrstr.appendAttributedString(NSAttributedString(attachment: attch)) textView.attributedText = attrstr textView
任何想法都非常欢迎,提前致谢!
var thumbnailImage: NSImage? = // some image var attachmentCell: NSTextAttachmentCell = NSTextAttachmentCell.initImageCell(thumbnailImage!) var attachment: NSTextAttachment = NSTextAttachment() attachment.attachmentCell = attachmentCell var attrString: NSAttributedString = NSAttributedString.attributedStringWithAttachment(attachment) self.textView.textStorage().appendAttributedString(attrString)
