iOS does have an API to scan 1D and 2D barcodes. But unfortunately we cannot scan multiple 1D barcodes. However we can still scan multiple 2D barcodes.
Can AVCaptureMetadataOutput detect multiple 1-Dimensional barcodes in a frame?
No. Only a single 1-dimensional code will be returned with each call to
AVCaptureMetadataOutputObjectDelegate
captureOutput:didOutputMetadataObjects:fromConnection:, and it will
correspond to the center-most decodable barcode in the rectOfInterest.
To answer your question we do have some third party bar code scanning library which can scan multiple barcodes. Below is the app/SDK which i have used personally.
