AVCapturePhotoOutput for iOS photo customization

The leader arranges the task, writes a photo function, the interface takes a photo with the system a little discrepancy

After the photo is taken, the bottom shows the photo taken. There is a cap on the photo taken.

Click the photo taken, you can preview, zoom in and out of view

The system must not take photos, can only be customized, did not mention whether to take photos to prohibit the demand of sound [non-candid, serious people]

In principle can be simple is not complex, brick AVCAPTUREPHOTOOUTPUT

First, you need a temporary layer for the current scene, not mentioned here. Refer to the previous post.

Next, define session + photoOutput

Third, define the photo event

Finally, the agent gets the photo

serving

• Session defines the input Settings

  self.session = [[AVCaptureSession alloc] init];
  self.session.sessionPreset = AVCaptureSessionPresetPhoto;
  AVCaptureDevice *device = [AVCaptureDevice defaultDeviceWithMediaType:AVMediaTypeVideo];
  self.dInput = [AVCaptureDeviceInput deviceInputWithDevice:device error:nil];
  if ([self.session canAddInput:self.dInput]) {
      [self.session addInput:self.dInput];
  }

• Camera Scene Layer

  self.preView = [[AVPreView alloc] init];
  self.preView.backgroundColor = [UIColor colorWithHexs:0x3f3f3f];
  self.preView.session = self.session;
  [self.preView setVideoOrientation:AVCaptureVideoOrientationLandscapeRight];
  [self.view addSubview:self.preView];
  [self.preView mas_makeConstraints:^(MASConstraintMaker *make) {
      make.left.equalTo(self.view);
      make.top.equalTo(self.topView.mas_bottom);
      make.bottom.equalTo(self.collect.mas_top);
      make.right.equalTo(rightView.mas_left);
  }];

• Set the photoOutput

  self.photoOutput = [[AVCapturePhotoOutput alloc] init];
  if ([self.session canAddOutput:self.photoOutput]) {
      [self.session addOutput:self.photoOutput];
  }
  [self.photoOutput.connections.lastObject setVideoOrientation:AVCaptureVideoOrientationLandscapeRight];

• session start

  [self.session startRunning];

• Photo click

  AVCapturePhotoSettings *set = [AVCapturePhotoSettings photoSettings];
  [self.photoOutput capturePhotoWithSettings:set delegate:self];

• AVCapturePhotoCaptureDelegate

  #pragma mark - AVCapturePhotoCaptureDelegate -(void)captureOutput:(AVCapturePhotoOutput *)output DidFinishProcessingPhoto photo: (AVCapturePhoto *) error: (NSError *) error API_AVAILABLE (ios (11.0)) {if (! NsData *data = [Photo FileDatarePresentation]; UIImage *image = [UIImage imageWithData:data]; // image}}

See me Tomorrow, haha
