数组有额外的符号，而不是我添加的，使用 Objective C 修剪 iPhone 应用程序中的数组

发布于 2024-12-01 06:29:24 字数 599 浏览 1 评论 0原文

在我的 iPhone 应用程序中，我将字符串值添加到数组中，第一个 strSelectedDir 值将是 xxx-jan16-2011-10.30AM 稍后其值将是 xxx-feb16-2011-02.30PM ,,我使用以下代码将这 2 个值添加到数组 arrDownloadedDirNames 中，

 [arrDownloadedDirNames addObject:strSelectedDir];

但在输出数组中一些新行符号(\n ) 和像 \ "" 这样的符号如下所示，

(
    "(\n    \"xxx-jan16-2011-10.30AM\"\n)",
    "xxx-feb16-2011-02.30PM"
)

but i want array should be like this with no extra symbols other than which are in the input string 

(
    xxx-jan16-2011-10.30AM ,
    xxx-feb16-2011-02.30PM
)

我该怎么做，为什么要添加额外的符号？我怎样才能删除那些请任何人帮助我，提前致谢

我猜你的字符串来自 Parse 或者其他什么，对吗？
您看到的额外符号称为转义序列：

\n = linebreake
\" = "

你可以很容易地替换这个角色。

NSMutabeString *yourNewString = [NSMutabelString stringWithFormat:@"%@",[arrDownloadDirNames objectAtIndex:i]
[yourNewString replaceOccurrencesOfString:@"\n    \""  withString:@""  options:NSLiteralSearch range:NSMakeRange(0, [yourNewString length])];
[yourNewString replaceOccurrencesOfString:@"\"\n"  withString:@""  options:NSLiteralSearch range:NSMakeRange(0, [yourNewString length])];

干杯

I guess your String is from a Parse or something right?
The extra symbols you see are called Escape Sequences:

\n = linebreake
\" = "

You can replace this Charakters pretty easy.

NSMutabeString *yourNewString = [NSMutabelString stringWithFormat:@"%@",[arrDownloadDirNames objectAtIndex:i]
[yourNewString replaceOccurrencesOfString:@"\n    \""  withString:@""  options:NSLiteralSearch range:NSMakeRange(0, [yourNewString length])];
[yourNewString replaceOccurrencesOfString:@"\"\n"  withString:@""  options:NSLiteralSearch range:NSMakeRange(0, [yourNewString length])];
