有人能帮我把rtf文本加载到Swift 2的UITextView中吗?我得到的答案已经过时了。这些文本是关于如何玩我在应用程序中编写的游戏的说明。到目前为止,我所能做的就是把所有rtf文本复制并粘贴到占位符框中。这在模拟器中适用于iPhone。但在iPad模拟器或iPhone 6 Plus中尝试时,当我这样做时,会出现双垂直滚动条。看起来很乱。
我现在也有一个真实的的纯文本相同的文件,所以我们可以尝试。

                self.textView.attributedText = attributedStringWithRtf

您可以在Swift 2中使用以下代码读取rtf文件。

加载RTF文件

let path = NSBundle.mainBundle().pathForResource("sample-rtf", ofType: "rtf")

    let contents: NSString
    do {
        contents = try NSString(contentsOfFile: path!, encoding: NSUTF8StringEncoding)
    } catch _ {
        contents = ""
    }

    let array : NSArray = contents.componentsSeparatedByString("\n");

    self.textView.text  = (array.objectAtIndex(0) as! String);

    //self.textView.text  = contents as String

尝试使用纯文本(txt)文件而不是rtf文件。RTF文件也包含文本的格式信息。这是你在阅读内容后看到的不必要的东西。
在Mac文本编辑中打开rtf文件,然后按Cmd+Shift+T(这会将其转换为纯文本并删除所有格式),然后保存为txt。

加载文本文件

let path = NSBundle.mainBundle().pathForResource("sample-text", ofType: "txt")

    let contents: NSString
    do {
        contents = try NSString(contentsOfFile: path!, encoding: NSUTF8StringEncoding)
    } catch _ {
        contents = ""
    }

     self.textView.text  = contents as String

Swift 3代码:

if let rtfPath = Bundle.main.url(forResource: "description_ar", withExtension: "rtf") {
    do {
        let attributedStringWithRtf:NSAttributedString = try NSAttributedString(url: rtfPath, options: [NSDocumentTypeDocumentAttribute:NSRTFTextDocumentType], documentAttributes: nil)
            self.textView.attributedText = attributedStringWithRtf
        } catch {
            print("We got an error \(error)") //or handle how you want
        }
}
