こんにちは!
Swift3.0になって、これまで使っていたエンコーディングができなくなりました。
Swift3.0では
swift3.0
1str.addingPercentEncoding(withAllowedCharacters:NSCharacterSet.xxx)
なメソッドを使わないといけなくなったのですが、
xxxに何を指定したらいいか、わかりません。
withAllowedCharacters:もあっているかわかりません。
PHPのurl encode関数と同じエンコーディングをしたいです。
アルファベットと数字とピリオド以外の特殊文字と日本語だけを%xxxxxに
したいです。
どうコードを書けばいいでしょうか?
困っています。
助けてください。よろしくお願いします。

自己解決
Swift
1 let encodedString = CFURLCreateStringByAddingPercentEscapes( 2 nil, 3 originalString as CFString!, 4 nil, 5 "!*'();:@&=+$,/?%#[]" as CFString!, 6 CFStringBuiltInEncodings.UTF8.rawValue
が手取り早かったです。Swift3.0でも残っていて良かったー。

以下のサイトに載っていることで解決できると思います。
swift
1if let u: String = "http://www.test.com/あいうえお".addingPercentEncoding(withAllowedCharacters: CharacterSet.urlQueryAllowed) { 2 print(u) 3 //=> http://www.test.com/%E3%81%82%E3%81%84%E3%81%86%E3%81%88%E3%81%8A 4}
定義に飛ぶと以下のように使いえるものも分かると思います。
swift
