A barcode and qr code scanner that wraps the iOS7 scanning capabilities in a UIViewController

bcscanner's Issues

I do not see a HUD

Is there supposed to be a HUD? I don't see any. It'd be nice to have. I see a HUD referenced in the code. How do I enable it?

Not all AVFoundation code types are supported

Not all code types that are supported by AVFoundation are added to BCScanner yet. Currently supported types are: QR, UPCE, EAN8 and EAN13.

The missing code types should be added as well.

[self updateRectOfInterest] in commit 7238790 breaks scan capture

After updating to latest develop commit, the scan capture doesn't work anymore. If I comment out the line 266: [self updateRectOfInterest] in BCScannerViewController, scanning works again.

Block based API as a category on `UIViewController`

To enable very easy single code scanning, there should be a category on UIViewController that can present the scanner view controller as a modal view controller, calls a completion handler if the first bar code is found and then close the scanner view controller.

Header comments should be without a leading asterisk

To be compatible to cocoadocs, the header comments should be without a leading asterisk in each line.

Old look:

/**
 * This is the gesture recognizer that is used to let the user focus and expose to a
 * specific point in the field of view. You can access this property when you want to
 * more precisely control what taps should be recognized.
 */

New look:

/**

Help understanding TODOs

Hey, I'm digging into you code but I could not understand these TODOs:

• When using multiple codes together with a hud immage the animation will break when relayouting the screen (e.g. when rotating).
• Not all supported code types of AVFoundation are added to BCScanner yet. Currently supported types are: QR, UPCE, EAN8 and EAN13.

Could you give me more details?

Codabar

Hi, is there any chance that the Codabar type can be read?

Thanks

HUD image animation broken after rotating

Summary:
When providing a HUD image while scanning for more than one code type, the HUD animation breaks when relayouting (e.g. rotating the device).

Steps to Reproduce:

1. Set the codeTypes property to at least two code types.
2. implement the delegate method scannerHUDImage: and return an image
3. see the animation on the screen and rotate the device

Expected Results:
The animation continues as before.

Actual Results:
The animation runs twice as fast.

How can I implement a I25 scanner?

https://en.wikipedia.org/wiki/Interleaved_2_of_5

How could I go about adding that? I can then contribute the code back to the project.

It should be possible to set an active scanner area

It should be possible to define an active scanner area in the view controller that is used for scanning for qr codes.

This might need to work nice with the hud image so that the hud image marks this area as well.

HUD image should be available when using the block based api

It should be possible to specify the hud image that should be used when using the block based api.
