1. 去到訊飛開放平臺建立應用並新增服務
2. 下載SDK，下載時需要選上專案的，必須選上相應的專案，不能用專案1下載的SDK和專案2的app ID結合使用（估計是訊飛綁定了，所以步驟1和步驟2也不能顛倒）
3. 拷貝下載的SDK中的iflyMSC.framework到桌面，然後拖到工程去

4. 選擇剛剛拖進的iflyMSC.framework，show in finder,然後按照下圖操作，雙擊右邊部分，會彈出一個大框，把iflyMSC.framework所在的資料夾拖到大框裡。
   

5. 新增類庫，如下圖
   

6. 在AppDelegate.m匯入標頭檔案iflyMSC/IFlyMSC.h 並新增一下程式碼

- (BOOL
 
)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {


    //訊飛
    NSString *initString = [[NSString alloc] initWithFormat:@"appid=%@",@"你的app ID"];
    [IFlySpeechUtility createUtility:initString];


    return YES;
}

/*
 訊飛
 */
 1. (BOOL)application:(UIApplication
 
 *)application openURL:(NSURL *)url sourceApplication:(NSString *)sourceApplication annotation:(id)annotation{
    [[IFlySpeechUtility getUtility] handleOpenURL:url];
    return YES;
}

-(UIInterfaceOrientationMask)application:(UIApplication *)application supportedInterfaceOrientationsForWindow:(UIWindow
 
 *)window
{
    return UIInterfaceOrientationMaskPortrait;
}

7.在下載的SDK裡面找到下圖的幾個檔案，並拖到工程

8.在你需要用到的控制器裡面匯入標頭檔案，並設定代理IFlySpeechRecognizerDelegate

#import "iflyMSC/IFlySpeechRecognizerDelegate.h"
#import "iflyMSC/IFlySpeechRecognizer.h"
#import "iflyMSC/IFlyMSC.h"
#import "IATConfig.h"
#import "ISRDataHelper.h"

9.宣告例項IFlySpeechRecognizer *_iFlySpeechRecognizer;在語音設別按鈕新增以下程式碼

if(_iFlySpeechRecognizer == nil)
    {
        [self initRecognizer];
    }
    [_iFlySpeechRecognizer cancel];

    //設定音訊來源為麥克風
    [_iFlySpeechRecognizer setParameter:IFLY_AUDIO_SOURCE_MIC forKey:@"audio_source"];
    //設定聽寫結果格式為json
    [_iFlySpeechRecognizer setParameter:@"json" forKey:[IFlySpeechConstant RESULT_TYPE]];
    [_iFlySpeechRecognizer setDelegate:self];

    BOOL ret = [_iFlySpeechRecognizer startListening];

    if (ret) {
        NSLog(@"start");
    }else{
        NSLog(@"error");
    }

10.其中initRecognizer方法如下

-(void)initRecognizer
{
    //單例模式，無UI的例項
    if (_iFlySpeechRecognizer == nil) {
        _iFlySpeechRecognizer = [IFlySpeechRecognizer sharedInstance];

        [_iFlySpeechRecognizer setParameter:@"" forKey:[IFlySpeechConstant PARAMS]];

        //設定聽寫模式
        [_iFlySpeechRecognizer setParameter:@"iat" forKey:[IFlySpeechConstant IFLY_DOMAIN]];
    }
    _iFlySpeechRecognizer.delegate = self;

    if (_iFlySpeechRecognizer != nil) {
        IATConfig *instance = [IATConfig sharedInstance];

        //設定最長錄音時間
        [_iFlySpeechRecognizer setParameter:instance.speechTimeout forKey:[IFlySpeechConstant SPEECH_TIMEOUT]];
        //設定後端點
        [_iFlySpeechRecognizer setParameter:instance.vadEos forKey:[IFlySpeechConstant VAD_EOS]];
        //設定前端點
        [_iFlySpeechRecognizer setParameter:instance.vadBos forKey:[IFlySpeechConstant VAD_BOS]];
        //網路等待時間
        [_iFlySpeechRecognizer setParameter:@"20000" forKey:[IFlySpeechConstant NET_TIMEOUT]];

        //設定取樣率，推薦使用16K
        [_iFlySpeechRecognizer setParameter:instance.sampleRate forKey:[IFlySpeechConstant SAMPLE_RATE]];

        if ([instance.language isEqualToString:[IATConfig chinese]]) {
            //設定語言
            [_iFlySpeechRecognizer setParameter:instance.language forKey:[IFlySpeechConstant LANGUAGE]];
            //設定方言
            [_iFlySpeechRecognizer setParameter:instance.accent forKey:[IFlySpeechConstant ACCENT]];
        }else if ([instance.language isEqualToString:[IATConfig english]]) {
            [_iFlySpeechRecognizer setParameter:instance.language forKey:[IFlySpeechConstant LANGUAGE]];
        }
        //0無標點返回
        [_iFlySpeechRecognizer setParameter:@"0" forKey:[IFlySpeechConstant ASR_PTT]];

    }
}

11.代理方法

- (void) onResults:(NSArray *) results isLast:(BOOL)isLast
{
    NSMutableString *resultString = [[NSMutableString alloc] init];
    NSDictionary *dic = results[0];
    for (NSString *key in dic) {
        [resultString appendFormat:@"%@",key];
    }
    NSString * resultFromJson =  [ISRDataHelper stringFromJson:resultString];


    NSLog(@"resultFromJson=%@",resultFromJson);
}
//識別會話錯誤返回
- (void)onError: (IFlySpeechError *) error
{
    //error.errorCode =0 聽寫正確  other 聽寫出錯
    NSLog(@"code=%d",error.errorCode);
    if(error.errorCode!=0){
        //出錯
    }
}
