Question

我想通过.txt文档并在NSStrings中存储文本块。我的问题是这个文档包含换行符，我不知道如何摆脱它们。如果我可以将每个单词放入有序的NSArray然后只是通过该数组并从中获取信息，那将是很好的。我会这样的：

// txt file
This is just a test.
End of the text file.

---

// NSArray and NSStrings
NSArray *wholeDocument =@"This","is","just","a","test","Foo","bar.", "End", "of", "the","text","file.";
NSString *beginDocument =@"This is just a test";
NSString *endDocument =@"End of the text file.";

Answer 1

试试这个：

NSString *str = [NSString stringWithContentsOfFile:@"file.txt"];
NSArray *arr = [str componentsSeparatedByCharactersInSet:[NSCharacterSet whitespaceAndNewlineCharacterSet]];

此处，arr将包含由空格或换行符分隔的所有单词。
