iOS SimulatorでiOS8を動かすとEUC-JPエンコードのバイト列をNSStringにするときにエラーとなる

Last updated at Posted at 2014-09-26

Summary

タイトルの通りなんですがEUC-JPエンコードのバイト列をNSStringにするときに以下のエラーが発生します。
iOS SimulatorをiOS7で動かすと正しく読み込めます。(Xcode6.0, Xcode6.1で確認)

Error Domain=NSCocoaErrorDomain Code=261 "The operation couldn’t be completed. (Cocoa error 261.)" UserInfo=0x7fdfe2657ef0 {NSFilePath=/Users/tetsuo/Library/Developer/CoreSimulator/Devices/766F5633-A7C6-45AE-AADF-A2182FA157EF/data/Containers/Bundle/Application/7DC78A9D-4BA7-44D2-9852-AC6A099014FE/TestApp3.app/eucdata.txt, NSStringEncoding=3}

Description

Xcodeでプロジェクトを適当につくって、以下のようなコードを書いて検証しました。
(Swiftで書くのは初めてなので、慣れないな...)

    @IBAction func actionHoge(sender: UIButton) {
        if let dataPath = NSBundle.mainBundle().pathForResource("eucdata", ofType: "txt") {
            var error : NSError?
            let str = NSString(contentsOfFile: dataPath, encoding: NSJapaneseEUCStringEncoding, error: &error)
            
            if let e = error {
                NSLog("%@", e)
            } else {
                NSLog("str: %@", str)
            }
        }
    }

ちょっと試した感じだと回避方法が見つからなかったので、Appleにお願いだな...
