how to remove spaces, brackets and " from nsarray

问题

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"
)

this is the output give as show there are spaces, brackets and " how could i remove them ? 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;295‌87,39957;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.

回答1:

Try stringByTrimmingCharactersInSet:

NSCharacterSet *charsToTrim = [NSCharacterSet characterSetWithCharactersInString:@"()  \n\""];
s = [s stringByTrimmingCharactersInSet:charsToTrim];

回答2:

try to use:

s = [s stringByReplacingOccurrencesOfString:@";"
                                     withString:@""];

it separates the numbers for you and you can work with them as i.e. NSInteger values.

NSString *_inputString = @"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";
NSString *_setCommonSeparator = [_inputString stringByReplacingOccurrencesOfString:@";" withString:@","];
NSArray *_separetedNumbers = [_setCommonSeparator componentsSeparatedByString:@","];

for (NSString *_currentNumber in _separetedNumbers) {
    NSInteger _integer = [_currentNumber integerValue];
    NSLog(@"number : %d", _integer);
}
