        Objective-Cologne 2013 — Mike Lee: "High Performance UIKit"

        Objective-Cologne 2013 — Mike Lee: "High Performance UIKit"

        Lemurs Chemistry: Water is a fast-paced game with intense graphics and audio that maintains buttery smooth performance, even on the original iPad. Its secret weapons? Objective-C and Interface Builder.

        If you think you need OpenGL to get good performance out of your game or custom interface on iOS, think again! The native toolchain provides everything you need to deliver bare-metal performance to your users.

        This isn't the same old tutorial on using Instruments, but the real life experiences of legendary product engineer Mike Lee as he's shipped some of the world's most notable apps.

        Half fishing story, half detective thriller, Mike's inimitable style will make you laugh and cry, and you might even learn a thing or two about delivering the surprise and delight your own apps will need to be successful.

            Objective-Cologne 2013 — Erik Romijn: "iOS security: super simple stuff"

            Objective-Cologne 2013 — Erik Romijn: "iOS security: super simple stuff"

            Our apps today store more and more sensitive information. As developers, it is our job to ensure this information is well protected. iOS comes with many built-in security features, and several APIs to help secure the user's data. Using these features is not incredibly hard, as long as you know about them, use them properly, and avoid their pitfalls.

            In this practical session, we'll demystify the details of built-in iOS features, like filesystem encryption. We'll look at the various APIs you can use to protect data, like Keychain, and how to use them properly. We'll also dive into many small but nasty potential issues, like the use of pasteboards. Lastly, we'll take a look at some examples of how not to do iOS security, and what we can learn from those.

            00:00 — Terminal & Jailbreak: Preparing Erik's Session...
            03:07 — Hackers can turn your computer into a bomb!
            08:24 — Always assume everyone is evil
            14:00 — Keychain: Never use "Always" or "AlwaysThisDeviceOnly"
            19:52 — Demo: How the "super secret password" was in NSUserDefaults
            25:26 — API Calls: All your users are evil
            32:37 — Even banks have security problems (right, ING?)
            35:21 — Private Pasteboards seem to be better in iOS 7
            40:24 — SQL Injections: Fix by using prepared statements
            45:16 — howtostoreiosdata.com: Your one stop point for iOS Security

                        Objective-Cologne 2013 — Matthew Bolton: "Get 5★ reviews for your app!"

                        Objective-Cologne 2013 — Matthew Bolton: "Get 5★ reviews for your app!"

                        Reviews can be important to apps, not just from the press, but perhaps more crucially from users. There are lots of fantastic apps in the App Store that come close to greatness, but issues both small and big can tarnish them. Apps that could get five-star reviews don't get the accolades they should.

                        The reasons can range from missing features, to UI issues, to perception problems – and they're usually fixable. This talk looks at examples of where other apps have gone slightly wrong, so developers can learn from others and make sure that their own apps get the scores they deserve.

                        00:00 — @stuffmc: "I've known Matthew for… days"
                        02:10 — I'm here to ask "Are you making a 5-star app?"
                        04:50 — Don't ask for a review at bad moments...
                        10:13 — Don't use notifications to annoy your users...
                        14:10 — Be carefull when changing standard user interface expectations
                        19:59 — An interface can be as good as a feature
                        26:45 — Inflexibility: features that people might not want at all
                        31:43 — If you're gonna be utilitarian, it should be simple to understand
                        37:36 — Don't promise too much, don't let people down
                        42:00 — Those things seems obvious.. but not...
                        47:24 — But these are all just examples. Be the exception!

                                Objective-Cologne 2013 — Ortwin Gentz: "Sneak peek into the bag of UI tricks"

                                Objective-Cologne 2013 — Ortwin Gentz: "Sneak peek into the bag of UI tricks"

                                UIs of iOS apps shouldn't only be easy and consistent to use but also have some personality. We walk through various tools and frameworks that help creating great UIs. We discuss how to add missing features to various UIKit controls such as buttons, labels and alerts, how to use UIWebViews in creative new ways and how to improve the performance of UITableViews.

                                    John talks about how you can keep on re-using not only your code but more importantly your more important asset: the domain you are passionate. Look at how John has "re-used" his MemoryMiner knowledge on Findery or other projects.

                                        Objective-Cologne 2013 — Alex Von Below: "Secrets of Memory Management with ARC"

                                        Objective-Cologne 2013 — Alex Von Below: "Secrets of Memory Management with ARC"

                                        Now that Apple has introduced Automated Reference Counting, we don't need to worry about Memory Management on iOS and OS X anymore, right? Well, while it may be true that ARC removes a lot of worry for a lot of people, it is well worth investigating it in detail.

                                        This session attempts to answer questions about how ARC works, and why knowing about traditional memory management is still important.

                                        While ARC is a solid technology, developer errors can manifest themselves in new, strange ways which are not always obvious to debug. This session will try to help.
