在iOS中读取文本文件 [英] Reading in a text file in iOS

问题描述

如何将文本文件读入textView?我有许多不同的文本文件，用户选择显示哪个文本文件，因此这就是为什么我不仅仅在其中有文件名的原因.我真的很困惑为什么这行不通.我在Apple Developer网站上有关从文件读取到字符串的部分中找到了它.

How do I read in a text file into a textView? I have many different text files and the user selects which one is displayed, so that is why I don't just have a file name in there. I'm really confused about why this doesn't work. I found it right on the Apple Developer site in the section about reading from files to strings.

NSString *path = [[NSBundle mainBundle] pathForResource:@"%@" ofType:@"txt"];
textFile = [[NSString alloc] initWithContentsofFile:path];
textView.text = textFile;

推荐答案

-pathForResource:ofType:不接受格式字符串.将 @％@" 替换为包含文件基本名称(即，文件名减去.txt扩展名)的字符串.

-pathForResource:ofType: doesn't accept a format string; replace the @"%@" with a string containing the base name of the file (i.e. the filename minus the .txt extention).

第二行和第三行也有不匹配的地方:您可能是说:

You've also got a mismatch on the second and third lines: you probably meant:

textView.text = textFile;
