显然该文件不在可写位置，因此我在documents目录中创建了该文件。
var paths = NSSearchPathForDirectoriesInDomains(.DocumentDirectory, .UserDomainMask, true)[0] as String
var path = paths.stringByAppendingPathComponent("data.plist")
var fileManager = NSFileManager.defaultManager()
if (!(fileManager.fileExistsAtPath(path)))
{
var bundle : NSString = NSBundle.mainBundle().pathForResource("data", ofType: "plist")
fileManager.copyItemAtPath(bundle, toPath: path, error:nil)
}
data.setObject(object, forKey: "object")
data.writeToFile(path, atomically: true)
然后，必须从文档目录中读取它。
var paths = NSSearchPathForDirectoriesInDomains(.DocumentDirectory, .UserDomainMask, true)[0] as String
var path = paths.stringByAppendingPathComponent("data.plist")
let save = NSDictionary(contentsOfFile: path)
