iOS语音书写功能（语音转文本）

Demo下载地址

最近在项目开发中，需要将语音识别转换成文本的功能。研究了下科大讯飞，附上Demo分享给大家。

研发前先得做一些准备。

1、注册科大讯飞开发者帐号（http://www.xfyun.cn）

2、下载开发平台（iOS、或Android，或其他）所需要的SDK（SDK包含：说明文档、SDK即iflyMSC.framework、Demo）

3、项目中添加SDK（添加时，先将SDK复制粘贴到项目文件，再通过addframe的方法添加到项目引用），及相关联的framework

添加方法：TARGETS-Build Phases-Link Binary With Libraries-"+"-Choose frameworks and libraries to add-add other，或选择对应的framework-add

4、使用时要添加对应的头文件

特别说明：

1、使用SDK关联的APPID存在于下载的Demo中，如果SDK有替换的话APPID应该跟着一起替换。

2、添加其他framework：

libz.tbd

libc++.tbd

CoreGraphics.framework

QuartzCore.framework

AddressBook.framework

CoreLocation.framework

UIKit.framework

AudioToolbox.framework

Foundation.framework

SystemConfiguration.framework

AVFoundation.framework

CoreTelephoney.framework

3、Bitcode属性设置为NO（TARGETS-Build Settings-Build Options-Enable Bitcode-NO）

4、在使用前，务必在AppDelegate的方法中"

- (BOOL)application:(UIApplication*)application didFinishLaunchingWithOptions:(NSDictionary*)launchOptions {}"进行初始化操作。

5、需要有网络的情况下才能使用。

如图

下载的科大讯飞SDK文件

Demo中的APPID

添加SDK，及添加关联framework

设置Bitcode属性为 NO
