里面包含了微信语音和图像，集成很简单，下载方demo后会有个文档，按照流程来（因为它只提供了真机的.a文件，所以只能用真机哦，不然会报错）

先用个有UI界面的sdk

1.装上sdk，引入相关包

2.设置 Build Settings
C++ Standard Library: libstdc++ 或 Compiler Default
Compile Sources As: Objective-C++ 或 将使用 SDK 的文件扩展名改为.mm

］

随便把一个文件后缀改成.mm不然会报错

3.添加代码

#import "CustomNewViewControl.h"
#import "WXSpeechRecognizerWithUI.h"
@interface CustomNewViewControl ()<WXVoiceWithUIDelegate> {
    WXSpeechRecognizerWithUI *_wxssui;
    __weak IBOutlet UILabel *label;
}
@property (weak, nonatomic) IBOutlet UIButton *button;

@end

@implementation CustomNewViewControl

- (void)viewDidLoad {
    [super viewDidLoad];
        _wxssui = [[WXSpeechRecognizerWithUI alloc] initWithDelegate:self andUserKey:@"248b63f1ceca9158ca88516bcb338e82a482ecd802cbca12"];
}
//点击事件
- (IBAction)buttonPressed:(UIButton *)sender {
    label.text = @"";
    [_wxssui showAndStart];
}

//代理 WXVoiceWithUIDelegate
- (void)voiceInputResultArray:(NSArray *)array{
    WXVoiceResult *result=[array objectAtIndex:0];
    [label setText:result.text];
}

无UI界面的sdk也差不多

注意：使用无界面UI需要遵守以下规则

微信语音开放平台免费为你的应用提供语音识别服务,你可以根据自己的风格自由制定 UI,但需在语音采集识别的窗口正确、完整的标注“Powered by 微信智能”或“语音技术由 微信智能提供”的字样。参考如下弹窗:

集成和上面一样，就不再重复
