如何删除空格、括号和“来自 nsarray [英] how to remove spaces, brackets and " from nsarray

问题描述

我有一个数组，我试图从 nsarray 中删除访问空格、方括号和 " 以使用 componentsSeparatedByString:@";"

I have an array where i am trying to remove the access spaces, brackets and " from the nsarray in order to use componentsSeparatedByString:@";"

NSArray *paths = [dic valueForKey:@"PATH"];

    for(NSString *s in paths)
    {
        NSLog(@"String: %@", s);
    }

String: (
"29858,39812;29856,39812;29800,39819;29668,39843;29650,39847;29613,39855;29613,39855;29613,39856;29605,39857;29603,39867;29603,39867;29599,39892;29596,39909;29587,39957;29571,40018;29563,40038;29560,40043"
)

这是输出给出的显示有空格，括号和我怎么能删除它们?由于这一行是该数组中的一个字符串 "29858,39812;29856,39812;29800,39819;29668,39843;29650,39847;29613,39855;29613,5,396;39639857;29603,39867;29603,39867;29599,39892;29596,39909;295‌ 87,39957;29571,40018;29563,40038;29563,40038;29563, 4行内的字符串代码为componentsSeparatedByString:@";" 它不能溢出所有有空格括号和里面.

As this line is juz a string inside that array "29858,39812;29856,39812;29800,39819;29668,39843;29650,39847;29613,39855;29613,‌​39855;29613,39856;29605,39857;29603,39867;29603,39867;29599,39892;29596,39909;295‌​87,39957;29571,40018;29563,40038;29560,40043" this line is a string inside the path array and i try using componentsSeparatedByString:@";" it could not be spilt all there are spaces brackets and " inside.
