Radar: Changing Metadata RectOfInterest causes pause

Nov 14, 2014

I found this issue when working on a barcode scanner included in an app I am working on for prod.ly. If you want to be efficient with barcode scanning and change the scanning region in the preview depending on device orientation you’ll notice this problem. Say, you want a wider active scanning area in landscape than you want in portrait.

When you change the rectOfInterest during rotation the preview video goes to black briefly and the main thread is blocked causing the rotation to start with a delay too.

Radar: UIImagePicker returns offset cropped image

Nov 12, 2014

This is the kind of bug you have to see for yourself to believe it. UIImagePickerController is one of the oldest classes in iOS and we’ve been using it for just as long to let the user pick images from their photo library. You can also allow “editing” which means the user can select a square region.

Unfortunatley – at least as of iOS 8.1 – the region you select does not match with the resulting cropped image that you are provided. It is shifted down by about 10 pixels from what the user selected.

Radar: Incorrect Horizontal Size Class

Nov 06, 2014

I found this bug while working on an app for our ProductLayer startup. There is a new segue “Present as Popover” which dynamically decides to present a view controller either modally full screen or as popover depending on the available screen width. On iPhone 6+ this shows as popover in landscape orientation and modally in portrait. On iPads it always shows as popover.

Proudly prod.ly

Oct 29, 2014

Disclaimer: I am the ProductLayer Developer Evangelist. My job is to convince you to build apps using our platform. Contact me if you have any questions.

Have you ever tweeted about a product that has you excited? Have you ever posted about a product on Facebook that really annoys you? Are you a “digital native” who feels right at home in social networks, keeping loose contacts with your friends and business associates?

Until today, whenever you would post something to a social network, this information would drown in the flood of other people’s posts. There was no way of finding other people’s opinions about physical products, except perhaps Amazon product reviews. But wouldn’t you trust more your friend’s opinions than those of complete strangers?

Today ProductLayer announces solutions to the problems above. We proudly present: prod.ly – a social network on which your friends share their opinions on various physical products.

AV Foundation: Code 39 Recognition Confusion

Oct 09, 2014

This is a bug report for AV Foundation. I noticed this problem when creating nice vector versions of the 1D barcodes used in figures in my book. The problem with this is that if you are scanning Code39 barcodes you have no way to determine whether it was one with or without check digit.

It’s filed as rdar://18566595 and on Open Radar.

Update Oct 17th: Added Apple’s response “behaves as intended” with a very good explanation given.
