Try using `stringByReplacingOccurrencesOfString:` of `NSString` or refer http://stackoverflow.com/questions/713918/replace-multiple-characters-in-a-string-in-objective-c — Akhilrajtr, Dec 17 '14 at 07:58
Double _colon_ would be `::`, presumably you mean the double quote `"`. — paxdiablo, Dec 17 '14 at 08:02

this will do it in swift

var stringwithoutquotes = string1.stringByReplacingOccurrencesOfString("\"", withString: "")
var removebracket1 = stringwithoutquotes.stringByReplacingOccurrencesOfString("[", withString: "")
var removebracket2 = removebracket1.stringByReplacingOccurrencesOfString("]", withString: "")

or you could do the entire thing in one line

var string2 = string.stringByReplacingOccurrencesOfString("\"", withString: "").stringByReplacingOccurrencesOfString("[", withString: "").stringByReplacingOccurrencesOfString("]", withString: "")

Here is another cleaner option in swift

var string = "\"hello[]" // string starts as "hello[]
var badchar: NSCharacterSet = NSCharacterSet(charactersInString: "\"[]")
var cleanedstring: NSString = (string.componentsSeparatedByCharactersInSet(badchar) as NSArray).componentsJoinedByString("")
//cleanedstring prints as "hello"

Swift 3:

let string = "\"hello[]" // string starts as "hello[]
let badchar = CharacterSet(charactersIn: "\"[]")
let cleanedstring = string.components(separatedBy: badchar).joined()
//cleanedstring prints as "hello"

Use following code:

NSCharacterSet *unwantedChars = [NSCharacterSet characterSetWithCharactersInString:@"\"[]"];
NSString *requiredString = [[_finalIDStr componentsSeparatedByCharactersInSet:unwantedChars] componentsJoinedByString: @""];

It's efficient and effective way to remove as many characters from your string in one single line..

A down vote without comment is a coward way of abusing some one. I want to see better solution/answer from the person who is giving down votes.. – Salman Zaidi Dec 17 '14 at 08:07
Just use the above mentioned code and if doesn't work go for other solution. BTW it will work.. – Salman Zaidi Dec 17 '14 at 08:24
It's the best solution here. – rdurand Dec 17 '14 at 09:38

Swift 4 (String Array) I wanted to convert String Array into String text to be placed in TextView:

FROM
["horse","cat","dog"]

TO
horse
cat
dog

var stringArray = ["horse","cat","dog"]

var stringArrayCleaned = stringArray.description.replacingOccurrences(of: "\"", with: "").replacingOccurrences(of: ",", with: "\n").replacingOccurrences(of: "[", with: "").replacingOccurrences(of: "]", with: "").replacingOccurrences(of: " ", with: "")


print(stringArrayCleaned)

Great solution, works like a charm. Thank you – Sipho Koza Jan 25 '22 at 10:57 — Sipho Koza, Jan 25 '22 at 10:57

You can try :

[[[_finalIDStr stringByReplacingOccurrencesOfString:@"\"" withString:@""] stringByReplacingOccurrencesOfString:@"[" withString:@""] stringByReplacingOccurrencesOfString:@"]" withString:@""];

I know this is an old question, but in case someone is still looking for answer.. I achieved this in swift using joined(separator:) see: apple documentation

var stringArray = ["alice","bob","cindy"]
print(stringArray.joined(separator: ","))

// this will print: alice,bob,cindy

NSString *str = ["658681","655917","655904"];
NSCharacterSet *cs = [NSCharacterSet characterSetWithCharactersInString:@"\"[]"];
str = [[string componentsSeparatedByCharactersInSet:cs] componentsJoinedByString:@""];

Not going to work. This will look for the exact string *"[]* and will not find any occurence. – rdurand Dec 17 '14 at 08:01
sorry my bad, fixed in answer. – ugur Dec 17 '14 at 08:03
Better, but your first line is still wrong. It will not create a string. – rdurand Dec 17 '14 at 08:05
But you are clever enough to surround it with `@""` right? – ugur Dec 17 '14 at 08:06
SO doesn't have a build-in compiler. I think anyone can solve such simple errors I have made in answer. Focusing on that is not constructive. – ugur Dec 17 '14 at 09:50
