Question

我正在尝试对字符串进行编码（通过HTTP post请求发送）以接受可以在iPhone上键入的所有字符。

以下适用于我在典型英语桌面键盘上尝试的任何角色

let userPassword = "password1"
let encodedPassword = userPassword.stringByAddingPercentEncodingWithAllowedCharacters(NSCharacterSet.alphanumericCharacterSet())

但不识别重音字符，如á，é，í，ó，ú，ü，ñ等等（可以通过按住a，e，i ...在标准iPhone键盘上访问）。是否有NSCharacterSet或简单的扩展名，其中包含标准iPhone键盘上的所有/所有字符？

编辑：这是我正在制作的请求的代码

let username = "joe"
let password = "pássword"
let encodedUsername = username.stringByAddingPercentEncodingWithAllowedCharacters(NSCharacterSet.alphanumericCharacterSet())
let encodedPassword = password.stringByAddingPercentEncodingWithAllowedCharacters(NSCharacterSet.alphanumericCharacterSet())

let request = NSMutableURLRequest(URL: NSURL(string: "https://www.url.com")!)
request.HTTPMethod = "POST"
let postString = "id="+encodedUsername+"&pw="+encodedPassword
request.HTTPBody = postString.dataUsingEncoding(NSUTF8StringEncoding, allowLossyConversion: false)
let task = NSURLSession.sharedSession().dataTaskWithRequest(request) {
        data, response, error in
    ...

只需在接受用户输入时添加此项，这样用户就无法添加任何特殊符号或重音字符，也无需使用允许的字符进行编码： -

#define ACCEPTABLE_CHARACTERS @"ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789_."

- (BOOL)textField:(UITextField *)textField shouldChangeCharactersInRange:(NSRange)range replacementString:(NSString *)string
{
         NSCharacterSet *acceptedInput = [NSCharacterSet characterSetWithCharactersInString:ACCEPTABLE_CHARACTERS];
        if (![[string componentsSeparatedByCharactersInSet:acceptedInput] count] > 1){
            NSLog(@"not allowed");
            return NO;
        }
        else{
            return YES;
        }
}
