IOS百度语音与二维码的生成实例教程

一. 我们这里需要用到两个第三方 baidu-voice-sdk-ios-1.6(百度语音)、libqrencode(二维码生成)

二. 在info.plist设置允许访问网络 添加app transport security settings 在他的下面再添加nsallowsarbitraryloads并把后面的no改为yes

三. 导入以下依赖库

glkit.framework

coretelephony.framework

avfoundation.framework

systemconfiguration.framework

audiotoolbox.framework

libz.tbd

security.framework

quartzcore.framework

coretext.framework

corelocation.framework

cfnetwork.framework

coregraphics.framework



// 导入头文件

#import "viewcontroller.h"

#import "bdrecognizerviewcontroller.h"

#import "bdrecognizerviewdelegate.h"

#import "bdvoicerecognitionclient.h"

#import "qrcodegenerator.h"



@interface viewcontroller ()<bdrecognizerviewdelegate>





@property(nonatomic,strong)bdrecognizerviewcontroller *bdvc; //语音界面

@property(nonatomic,strong)nsmutabledata *alldata;

@property(nonatomic,strong)bdrecognizerviewparamsobject *bdvp; //参数设置 key 秘





// 创建显示二维码和内容的属性

@property (weak, nonatomic) iboutlet uiimageview *image;

@property (weak, nonatomic) iboutlet uilabel *lable;



@end



@implementation viewcontroller



- (void)viewdidload {

    [super viewdidload];

    // 使用百度主题设置

    bdtheme *me = [bdtheme lightorangetheme];

    self.bdvc = [[bdrecognizerviewcontrolleralloc]initwithorigin:cgpointmake(20, 10) withtheme:me];

    // 设置为全屏幕

   self.bdvc.enablefullscreenmode = yes;

    // 设置代理

    self.bdvc.delegate = self;

    self.bdvp = [[bdrecognizerviewparamsobject alloc]init];

    // 设置appkey

    self.bdvp.apikey = @"anqlqinhgf2tl0gvp5xhncxm";

    self.bdvp.secretkey = @"c3d5f5f8ac5478e87802431389b2cba7";

}

// 识别语音

- (void)onrecorddataarrived:(nsdata *)recorddata samplerate:(int)samplerate{

    [self.alldata appenddata:recorddata];

}

// 把识别到的内容添加到lable上

- (void)onpartialresults:(nsstring *)results

{

    self.lable.text = results;

}

// 语音识别按钮 点击开始识别

- (ibaction)yuyinbutton:(id)sender {

    self.alldata = [[nsmutabledata alloc]init];

    [self.bdvc startwithparams:self.bdvp];

}

// 生成二维码按钮

- (ibaction)buttton:(id)sender {

    // 生成二维码按钮

     uiimage *img = [qrcodegenerator qrimageforstring:self.lable.textimagesize:self.image.frame.size.width];

    self.image.image = img;

}

// 清空内容

- (ibaction)clearbutton:(id)sender {

    self.lable.text = nil;



}
