使用 Swift 4 和 Xcode 从包中的 RTF 文件中加载数据的文本视图 [英] Load Text View with data from RTF file in bundle using Swift 4 and Xcode
问题描述
我目前正在阅读文本文件并将该信息加载到文本视图中.我有 100 多个项目,每个项目都有相当多的文本,因此这种方法效果很好.
I am currently reading text files and loading that information into a text view. I have over 100 items and quite a bit of text per item so this method works well.
我的问题是我想让一些文本加粗,但不能使用标准文本文件来做到这一点,所以我想知道如何修改我目前拥有的代码,以便它加载 RTF 文件的内容而不是文本文件,当然在文本视图中正确显示.
My problem is that I would like to make some text bold and can not do that using a standard text file so I am wondering how I can modify the code I currently have so that it loads the contents of a RTF file instead of the text file, and of course displays correctly in the text view.
let myString = String(indexNumber)
let detailFile = "detail" + myString
if let filepath = Bundle.main.path(forResource: detailFile, ofType: "txt") {
do {
let contents = try String(contentsOfFile: filepath)
detailsTextView.text = contents
} catch {
detailsTextView.text = detailFile + " contents could not be loaded"
}
} else {
detailsTextView.text = detailFile + " detail file could not be found"
}
推荐答案
Example from my own test code(RTF文件名为test.rtf",self.tv
是文本视图):
Example from my own test code (the RTF file is called "test.rtf", self.tv
is the text view):
let url = Bundle.main.url(forResource: "test", withExtension: "rtf")!
let opts : [NSAttributedString.DocumentReadingOptionKey : Any] =
[.documentType : NSAttributedString.DocumentType.rtf]
var d : NSDictionary? = nil
let s = try! NSAttributedString(url: url, options: opts, documentAttributes: &d)
self.tv.attributedText = s
