如何从Swift中的NSData初始化一个字符串 [英] How to initialise a string from NSData in Swift

问题描述

我一直在尝试从Swift中的NSData初始化一个字符串。

I have been trying to initialise a string from NSData in Swift.

在

In the NSString Cocoa Documentation Apple is saying you have to use this:

 init(data data: NSData!,
  encoding encoding: UInt)

但是苹果没有包含任何使用示例或在哪里放置init

however Apple did not include any example for usage or where to put the "init"

我试图将以下代码从obj-c转换为swift

I am trying to convert the following code from obj-c to swift

NSString *string;
string = [[NSString alloc] initWithData: data encoding: NSUTF8StringEncoding];

我一直在尝试许多可能的语法，如下面：

I have been trying a lot of possible syntaxes such as the following (of course it did not work):

var string:NSString!
string = init(data: fooData,encoding: NSUTF8StringEncoding)

推荐答案

这是你应该如何初始化 NSString ：

let datastring = NSString(data: fooData, encoding: NSUTF8StringEncoding)

此文档解释语法。
