替换“ “，字符在NSString中具有“\” （创建Unix路径） [英] Replace " " character in an NSString with "\ " (to create a Unix path)

问题描述

使用下列方法无效：

- (NSString *)stringByReplacingOccurrencesOfString:(NSString *)target withString:(NSString *)replacement

通过不工作我的意思是不做任何替换。它返回相同的精确字符串。

By doesn't work I mean does not do any replacement what so ever. It returns the same exact string.

有一个方便的方法吗？类似于：

Is there a convenience method to do this? Similar to:

- (NSString *)stringByReplacingPercentEscapesUsingEncoding:(NSStringEncoding)encoding

我的代码（只有一行）：

My code (just one line):

NSString *escapedPath = [pathToBeConverted stringByReplacingOccurrencesOfString:@" " 
                                                                     withString:@"\ "];

此外，我的编译器警告。这可能与这有很大关系：

Also, my compiler warning. Which likely has much to do with this:

warning: unknown escape sequence: '\040'

推荐答案

您应该使用 @\\ / code>而不是 @\。在C \ 是转义字符。您需要使用另一个 \ 转义它。

You should use @"\\ " instead of @"\ ". In C \ is the escape character. You need to escape it with another \.
