This is a test page for checking iOS system supported urls. It is a work in progress, I will continue to add links as I need them. Unfortunately wordpress.com, who host this page, suppress a few common url schemes including sms: and telprompt: so I’ll need to host elsewhere before it can be made comprehensive.
I have been enjoying iOS7 beta since the WWDC back in June. While I planned to update to the official version, the last beta release was pretty stable so I didn’t feel any particular urgency.
I figured I would do it soon and if I didn’t, apple would prompt (or even force) me to update over-the-air. What I did not expect was to find my device deactivated. Thanks Apple.
This post outlines the steps I took to get my phone working again. Continue reading
For the brave souls out there who trialled iOS seven beta and haven’t yet updated to the official release, today is a bad day. The beta has just expired and Apple has deactivated devices still using it.
Unfortunately, following device prompts to activate does not currently work. If you had Find my iPhone switched on you may struggle to restore without doing a complete device wipe first.
There is no argument to be had about whether ARC is beneficial. The reduction of boiler-plate memory code, is alone, enough to justify its use. The elimination of issues resulting from objects being incorrectly retained or released also saves developers untold hours debugging weird memory management issues.
However much ARC has simplified matters, issues will still arise if memory management is not adequately understood. These issues commonly fall into two categories, retain cycles and accessing released memory.
The straight-forward way to add additional Simulators to XCode is via Preferences. XCode 4.5.1 comes preloaded with iPhone/iPad Simulators for SDK 6.0 and the option to download 5.0 and 5.1.
However other versions are getting little love. If you need to support clients on older versions of iOS this is a problem. Luckily, adding older Simulators to XCode is easy.
NOTE: XCode 4.5 has dropped armv6 support so can no longer be used to develop for iOS <4.3. Adding armv6 simulators such as iOS 4.2 to XCode 4.5 will have no effect, they will simply be ignored.
