从 Swift 中的字符串中删除“\”（反斜杠）

Question

I have the following code:

let refreshedToken = FIRInstanceID.instanceID().token()

var encriptat3: String = "ope=sql&para=UPDATE xw_usuarios SET IDFIREBASE = '" + refreshedToken! + "' where USUARIO = '" + self.usuari + "'"
encriptat3 = encriptat3.stringByReplacingOccurrencesOfString("\\", withString: "", options: NSStringCompareOptions.LiteralSearch, range: nil)

And the final value of my string is :

"ope=sql&para=UPDATE xw_usuarios SET IDFIREBASE = \'XXXXXXX\' where USUARIO = \'99997\'"

And my ask is : How I can remove the "\" from my ending value and build my url correctly?

Currently I'm using Swift 2.3. Thanks.

Answer 1

swift 3

let string1 = "ios\\programmer"
let string2 = string1.replacingOccurrences(of: "\\", with: "")
print("string2 --%@",string2);

Answer 2

let aString = "ope=sql&para=UPDATE xw_usuarios SET IDFIREBASE = \'XXXXXXX\' where USUARIO = \'99997\'"
let newString = aString.replacingOccurrences(of: "\\", with: "")

EDIT:

Which version of Xcode are you using? Did you import Fondation?

let aString = "ope=sql&para=UPDATE xw_usuarios SET IDFIREBASE = \'XXXXXXX\' where USUARIO = \'99997\'"

let newString = (string as NSString).stringByReplacingOccurrencesOfString("\\", withString: "")

Answer 3

var val = your string

val = val.replacingOccurrences(of: "your replace string here(like \,)", with: "")
