替换数组中的字符串

Question

    NSArray *ArtistNames = [RawData componentsMatchedByRegex:regEx1]; 
    NSCharacterSet *doNotWant = [NSCharacterSet characterSetWithCharactersInString:@"'"];
    ArtistNames = [[ArtistNames componentsSeparatedByCharactersInSet: doNotWant] componentsJoinedByString: @"'"];

那是我的代码,基本上我不能使用它,因为ArtistNames是一个数组而不是字符串,我将如何通过这个？

我想你是以错误的顺序调用你的方法.尝试将其分成多个语句.

// The separator should be some string of characters guaranteed to not be in any of the strings in the array.
#define SEPARATOR @"---***---"

NSArray *artistNames = [RawData componentsMatchedByRegex:regEx1]; 
NSString *doNotWant = @"'"
NSString *combinedNames = [artistNames componentsJoinedByString:SEPARATOR];
combinedNames = [combinedNames stringByReplacingOccurrencesOfString:doNotWant withString:@""];
artistNames = [combinedNames componentsSeparatedByString:SEPARATOR];
