我在获取NSTextAttachment图像以在OS X应用程序的NSTextView中工作时遇到问题.
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 我正在使用XCode 7.两个游乐场都可以下载here. 任何想法都非常欢迎,提前致谢! 解决方法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) (编辑:李大同) 【声明】本站内容均来自网络,其相关言论仅代表作者个人观点,不代表本站立场。若无意侵犯到您的权利,请及时与联系站长删除相关内容! |
