目标C URL与垂直管道/栏

Question

我试图在URL中有垂直管道

输入字符串:http://testURL.com/Control?command=dispatch|HOME|ABC:用户名

-(NSString *)getURLEncodedString:(NSString *)stringvalue{
NSMutableString *output = [NSMutableString string];
const unsigned char *source = (const unsigned char *)[stringvalue UTF8String];
int sourceLen = strlen((const char *)source);
for (int i = 0; i < sourceLen; ++i) {
    const unsigned char thisChar = source[i];
    if (thisChar == ':' || thisChar == '/' || thisChar == '?' || thisChar == '=' || thisChar == '|' || thisChar == '.' || thisChar == '-' || thisChar == '_' || thisChar == '~' ||
               (thisChar >= 'a' && thisChar <= 'z') ||
               (thisChar >= 'A' && thisChar <= 'Z') ||
               (thisChar >= '0' && thisChar <= '9')) {
        [output appendFormat:@"%c", thisChar];
    } else {
        [output appendFormat:@"%%%02X", thisChar];
    }
}
return output;
}

调用上述方法后输出字符串:http://testURL.com/Control?command=dispatch|HOME|ABC:User%20Name

现在，如果我将上面的编码字符串传递给[[NSURL URLWithString:encodedString];

我得到域名=NSURLErrorDomain Code=-1000 "坏URL" UserInfo=0xae9d760 {NSUnderlyingError=0xaec8ed0 "坏URL"， NSLocalizedDescription=坏URL}

有关于这个的输入吗?我希望URL看起来像encodedString.

谢谢!

我真的看不到手动编码/转义字符串的理由…无论如何，这将工作得很好:

NSString *urlString = @"http://testURL.com/Control?command=dispatch|HOME|ABC:User Name";
NSURL *url = [NSURL URLWithString:[urlString stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]];

输出:

http://testURL.com/Control?command=dispatch%7CHOME%7CABC:User%20Name

似乎NSURL不喜欢竖条毕竟，你没有在你的方法中编码，从而得到一个bad URL代码。
