'How to change camera attributes (eg. ISO) and let AVCaptureVideoPreviewLayer display dynamicly
When using device lock and setting device.activeFormat variables to take photo, the settings will be effective in photo out rather than AVCaptureVideoPreviewLayer display dynamicaly, does anyone know how to solve or do it? Swift or Objective-C example is helpful.
I'll tried to set device.activeFormat variables and then add AVCaptureVideoPreviewLayer into UIView more times, but some errors was happend.
