第一步：导入第三方
1.Baidu-Voice-SDK-iOS-1.6.2(百度语音)
2.JSONKit
3.libqrencode（二维码生成）
第二步：添加依赖库
1.CoreGraphics.framework
2.CFNetwork.framework
3.CoreLocation.framework
4.CoreText.framework
5.QuartzCore.framework
6.Security.framework
7.libz.tbd
8.AudioToolbox.framework
9.SystemConfiguration.framework
10.AVFoundation.framework
11.CoreTelephony.framework
12.GLKit.framework
13.libBDVoiceRecognitionClient.a
第三步：关闭ARC
Bulid Phases —> JSONKit.m
-fno-objc-arc
第四步：修改其他的连接器标志
Bulid Settings —> Other Linker Flags
-ObjC
第五步：导入头文件
#import "BDRecognizerViewController.h"
#import "BDRecognizerViewDelegate.h"
#import "BDVoiceRecognitionClient.h"
#import “QRCodeGenerator.h"
第六步：代码
@interface ViewController (){
//语音界面
BDRecognizerViewController *bdrv;
NSMutableData *allData;
//参数设置 key 秘钥
BDRecognizerViewParamsObject *bdvp;
UILabel *label;
}
@end
@implementation ViewController

//Lable初始化

//主题设置

bdvp.secretKey = @"c3d5f5f8ac5478e87802431389b2cba7";
}
//点击说话
-(void)click{
allData = [[NSMutableData alloc]init];

}
// 点击清除
-(void)qingchu{

}
// 点击生成二维码

// 把生成的二维码展示在图像框上
imgV.image = img;
}
/**
* @brief 录音数据返回
* @param recordData 录音数据
* @param sampleRate 采样率
*/
- (void)onRecordDataArrived:(NSData *)recordData sampleRate:(int)sampleRate{
[allData appendData:recordData];

//此方法是将语音传递到lable上
- (void)onPartialResults:(NSString *)results
