类似于微信的点击拍照 , 长按拍视频的功能.
导入框架

#import <AVFoundation/AVFoundation.h>

在需要进行录屏的时候,创建视频流和音频流的输入输出流, 代码如下:

 NSArray *devicesVideo = [AVCaptureDevice devicesWithMediaType:AVMediaTypeVideo];
    NSArray *devicesAudio = [AVCaptureDevice devicesWithMediaType:AVMediaTypeAudio];

    self.videoInput = [AVCaptureDeviceInput deviceInputWithDevice:devicesVideo[0] error:nil];

    AVCaptureDeviceInput *audioInput = [AVCaptureDeviceInput deviceInputWithDevice:devicesAudio[0] error:nil];

    self.videoDevice = devicesVideo[0];

    self.videoDataOut = [[AVCaptureVideoDataOutput alloc] init];
    self.videoDataOut.videoSettings = @{(__bridge NSString *)kCVPixelBufferPixelFormatTypeKey:@(kCVPixelFormatType_32BGRA)};
    self.videoDataOut.alwaysDiscardsLateVideoFrames = YES;
    [self.videoDataOut setSampleBufferDelegate:self queue:self.recodingQueue];

    self.audioDataOut = [[AVCaptureAudioDataOutput alloc] init];
    [self.audioDataOut setSampleBuf
