Question

let username = "operator"
let password = "pass"
let loginString = NSString(format: "%@:%@", username, password)
let loginData: NSData = loginString.dataUsingEncoding(NSUTF8StringEncoding)!
let base64LoginString = loginData.base64EncodedStringWithOptions(NSDataBase64EncodingOptions.fromMask(0))

// create the request
let url = NSURL(string: "myurl")
let request = NSMutableURLRequest(URL: url)
request.HTTPMethod = "GET"
request.setValue("Basic \(base64LoginString)", forHTTPHeaderField: "Authorization")

上面的代码在Xcode 6.1之前运行良好，但现在我在base64LoginString常量上出错了。

/Users/Joel/Project/MapViewController.swift:31:74: 'NSDataBase64EncodingOptions.Type' does not have a member named 'fromMask'

我对Swift相对较新，并且还想就如何解决此类问题提出一些建议，而不必发布到StackOverflow。

Answer 1

当前版本的Swift中不再存在fromMask()构造函数。要指定＆＃34;无选项＆＃34;，请使用

let base64LoginString = loginData.base64EncodedStringWithOptions(NSDataBase64EncodingOptions(0))

或只是

let base64LoginString = loginData.base64EncodedStringWithOptions(nil)

对于 Swift 2 （比较https://stackoverflow.com/a/32499968/1187415）：

let base64LoginString = loginData.base64EncodedStringWithOptions([])

Swift 3：

let base64LoginString = loginData.base64EncodedString()

Swift - base64EncodingStringWithOptions无效Xcode 6.1
