在iphone应用程序中修剪objective c中的NSstring时出现问题

我有一个类似“qytwyqteqe”的字符串，我只想要qytwyqteqe，不想要符号“”

我试着用下面的代码来修剪这个字符串，但是它的给出错误，任何人都可以帮我，请提前修改

   [[strTrimmedDownloadedDirNames replaceOccurrencesOfString:@"""  withString:@"" options:NSLiteralSearch range:NSMakeRange(0, [strTrimmedDownloadedDirNames length])];

its giving error for this one @""" 
error:  missing terminating ""

编辑：

实际上我有一个这样的数组

arrConvertedDirNames:(
    "(\n    \"(\\n    \\\"Sudha-feb16-2011-02.30PM\\\"\\n)\"",
    "\n    \"Tharanga-jan16-2011-10.30AM\"\n)\n"
)

我做了以下替换来删除转义序列

NSMutableString *strTrimmedDownloadedDirNames = [NSMutableString stringWithFormat:@"%@",[arrDownloadedDirNames objectAtIndex:0]];

     [strTrimmedDownloadedDirNames replaceOccurrencesOfString:@"\\\""  withString:@"" options:NSLiteralSearch range:NSMakeRange(0, [strTrimmedDownloadedDirNames length])];

    [strTrimmedDownloadedDirNames replaceOccurrencesOfString:@"\n"  withString:@"" options:NSLiteralSearch range:NSMakeRange(0, [strTrimmedDownloadedDirNames length])];

    [strTrimmedDownloadedDirNames replaceOccurrencesOfString:@"\n    \""  withString:@""  options:NSLiteralSearch range:NSMakeRange(0, [strTrimmedDownloadedDirNames length])];

    [strTrimmedDownloadedDirNames replaceOccurrencesOfString:@"\"\n"  withString:@""  options:NSLiteralSearch range:NSMakeRange(0, [strTrimmedDownloadedDirNames length])];

     [strTrimmedDownloadedDirNames replaceOccurrencesOfString:@"\\n"  withString:@""  options:NSLiteralSearch range:NSMakeRange(0, [strTrimmedDownloadedDirNames length])];

    [strTrimmedDownloadedDirNames replaceOccurrencesOfString:@")"  withString:@""  options:NSLiteralSearch range:NSMakeRange(0, [strTrimmedDownloadedDirNames length])];

    [strTrimmedDownloadedDirNames replaceOccurrencesOfString:@"("  withString:@"" options:NSLiteralSearch range:NSMakeRange(0, [strTrimmedDownloadedDirNames length])];

    [strTrimmedDownloadedDirNames replaceOccurrencesOfString:@")\" "  withString:@"" options:NSLiteralSearch range:NSMakeRange(0, [strTrimmedDownloadedDirNames length])];


     [strTrimmedDownloadedDirNames replaceOccurrencesOfString:@"\""  withString:@"" options:NSLiteralSearch range:NSMakeRange(0, [strTrimmedDownloadedDirNames length])];


    [strTrimmedDownloadedDirNames replaceOccurrencesOfString:@" "  withString:@"" options:NSLiteralSearch range:NSMakeRange(0, [strTrimmedDownloadedDirNames length])];

    [strTrimmedDownloadedDirNames replaceOccurrencesOfString:@"\""  withString:@" " options:NSLiteralSearch range:NSMakeRange(0, [strTrimmedDownloadedDirNames length])];
now am getting this array
arrConvertedDirNames:(
    "Sudha-feb16-2011-02.30PM",
    "Tharanga-jan16-2011-10.30AM"
)

但是这个数组应该是这样的

arrConvertedDirNames:(
    Sudha-feb16-2011-02.30PM ,
    Tharanga-jan16-2011-10.30AM
)

怎样做才能使数组如此，请任何人帮我转义一下你需要的

“

，意思是：

此：

replaceCurrencesofString:@“

---

应该是：

replaceCurrencesofString:@“\”

您需要转义

“

，意思是：

此：

replaceCurrencesofString:@“

应该是：

replaceCurrencesofString:@“\”

be小心地返回一个新字符串，该字符串由从给定字符集中包含的接收方字符的两端删除而成

be小心地返回一个新字符串，该字符串通过从给定字符集中包含的接收方字符的两端删除而生成。

“\”应用作“转义字符”。“\”应用作“转义字符”。

NSCharacterSet *charterSet = [NSCharacterSet characterSetWithCharactersInString:@"""];
stringWithoutCurrentSymbol = [stringWithAnySimbols stringByTrimmingCharactersInSet:charterSet];
