Developers received mail from app inviting them to join the waiting list for their new app analytics service. Such a service is long overdue and several businesses are based solely on there not having been any offering by Apple so far. That is about to change.
Our Featured Part
New version 2.0 now fully supports iOS 5 through iOS 8 on all iPhones and iPads.
Just like the passcode lock mechanism of the iPhone, you can allow your users to set a 4-digit PIN for your own app. Then when starting your app’s personal data will only be available to the user.
It mimics the animations of the original for entering and confirming the PIN.
Our Featured App
Big red LED digits allow you to see the timer even at great distance so you are free to move while you give the talk of your life. SpeakerClock emulates the famous countdown clock that all speakers at TED conferences need to adhere to.
The latest version is a universal app with HD-support for iPad, multiple presets and lots of usability enhancements. New portrait support allows you to put your iPhone/iPad in the cradle and still use SpeakerClock. Now the whole screen flashes if you transition into a new phase of your speech.
The Latest From the Cocoanetics Blog
I published a section from my book Barcodes with iOS on DZone. My book is not only about barcodes but also gives short introductions to a plethora of other frameworks which you might not normally come into contact with.
The Core Graphics framework is written in pure C, meaning that it’s impossible to use CGImage instances directly with UIKit. Apple created UIImage as an Objective-C wrapper class around CGImage to bridge the gap. We explore Core Image in this article.

If your app contains frameworks or extensions you are recently beginning to notice a new warning popping up when building for releases: “skipping copy phase strip, binary is code signed”. Here’s how to fix it.
Working on an issue that has been reported for Notepad Classic 2007 (currently free on App Store) I found that UITextView has problems keeping the scroll position when showing or hiding the keyboard.
This issue didn’t occur on iOS 7 and I wasted more than 5 hours trying to come up with a workaround. The problem is that showing and hiding the keyboard is causing superflous calls to layoutSubviews on the text view which causes it to change the contentSize and contentOffset. This gets further complicated by UITextView dynamically changing the contentSize as you scroll down through text that is longer than a few pages.
It is rare that I am so confounded by a bug, so I even opened a DTS call for it, hoping that there is a workaround for this problem.

Who is Cocoanetics?
The word Cocoanetics comes from the words Cocoa (the framework we use to program iOS apps) and Genetics (to build, make up). It simply states that we have living and breathing iOS development a level even deeper than “in your blood”.
Our apps and parts are often experiments, mostly pieces of art, but always carefully handcrafted. We’re still learning and getting better at coding every day. You benefit from this because our code gets better all the time and we share what we learn on our blog.
