Question

有人可以帮我用Swift 2将rtf文本加载到UITextView中吗？我得到的答案已经过时了。该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，我所能做的就是将所有rtf文本复制并粘贴到占位符框中。这适用于模拟器中的iPhone，但是当我在iPad模拟器或iPhone 6 Plus中尝试时，出现这种情况时会出现双垂直滚动条。它看起来很乱。

我现在也有一个相同文件的真实纯文本，所以我们也可以试试。

Swift 3

def function_1():
    yield "start_function_2"
    counter = 0
    while True:
       counter += 1
       print counter


def function_2():
    second_counter = 0
    while True:
       second_counter += 1
       print second_counter

def main():
    return render_template("index.html")

@app.route("/start_functions", methods=["POST"])
def start_functions():
    data = request.data
    if request.method == "POST":
        for i in function_1(data):
           if (i == "start_function_2"):
              function_2()

if __name__ == "__main__":
    app.run(dhost="0.0.0.0", port=port)

if let rtfPath = NSBundle.mainBundle().URLForResource("description_ar", withExtension: "rtf") 
{
    let attributedStringWithRtf = NSAttributedString(fileURL: rtfPath, options: [NSDocumentTypeDocumentAttribute:NSRTFTextDocumentType], documentAttributes: nil, error: nil)
    self.textView.attributedText = attributedStringWithRtf
}

您可以在Swift 2中使用以下代码阅读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。 RTF文件也包含有关文本的格式信息。这是你在阅读内容后看到的不必要的东西。

在Mac TextEdit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），然后另存为txt。

加载文字文件

    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
        }
}
