SDK名称
Baidu-Voice-SDK-iOS-1.6
libqrencode
一.导入依赖库
GLKit.framework
CoreTelephony.framework
AVFoundation.framework
SystemConfiguration.framework
AudioToolbox.framework
libz.tbd
Security.framework
QuartzCore.framework
CoreText.framework
CoreLocation.framework
CFNetwork.framework
CoreGraphics.framework
二.导入头文件
#import "BDRecognizerViewController.h"
#import "BDRecognizerViewDelegate.h"
#import "BDVoiceRecognitionClient.h"
#import "QRCodeGenerator.h"
在编写程序的过程中，即使编译通过，但是在运行的过程中，偶尔会有类似 unrecognized selector sent to instance 的错误，为了避免该错误，需要到 target -> Build Settings 中修改 Other Linker Flags 的值，将其设置为 -ObjC，该值意在将静态库中所有的Objective-C 类和分类都加载到最后的可执行文件中。
另外，Other Linker Flags 还可以设置其他的值：
-all_load 会将库中所有的的目标文件都加入到可执行文件中，这样做会导致一个问题，如果引用了两个静态库，而这两个静态库恰好都引用了同一个第三发库，那么会报重复定义的错误 duplicate symbol。
-force_load 该值与 -all_load 相同，只是其后面需要指定具体要全部加载的库的路径，而其他库仍按需加载。
