A few months ago I mentioned a tutorial explaining basic use of the iBeacons API showing how to detect nearby iBeacons transmitters.
Here’s a tutorial by Craig Gilchrist explaining how to create a simple iBeacons app that adjusts based on proximity.
The tutorial explains step-by-step how to create a treasure hunting application that changes the receiver app as it gets closer to the transmitter by changing the user’s screen, and playing different sounds. The example project sets it up so that an iPad acts as a transmitter, and iPhones as a receiver from the same code base.
I’ve mentioned a few projects that use objective-c method swizzling to change existing components for the better such as UIMenuItem-CXAImageSupport which swizzles the drawTextInRect method of a UIMenuItem allowing you to use images as a menu item.
The problem with method swizzling is that it can lead to horrendous bugs that can seem impossible to debug without a good understanding of the code used.
Previously I mentioned a nice source code example demonstrating the basics of iOS 7′s Multipeer Connectivity API.
Here’s a tutorial from Gabriel Theodoropoulous explaining the basics of using the Multipeer Connectivity API through the building of a simple app.
Some of the topics covered in the tutorial include:
- how to discover and connect to nearby devices
- how to set up a simple chat between connected devices
- how to share files between devices
A few months ago I mentioned an in-depth series of tutorials covering the new multitasking APIs added in iOS 7.
Here’s a nice straightforward tutorial from Brian Mayo over at Captech Consulting with a nice over of the background multitasking with an example project.
The tutorial explains how to set up background fetching, background transfers, and remote notifications and provides a simple example demonstrating how to use the background transfer service APIs to download data.
I’ve mentioned a number of libraries for creating notification alerts from users, most recently CSNotification that allows you to create iconized notifications with background blurring in a clean iOS 7 inspired style.
Here’s a library from Collin Ruffenac that allows you to create stylish animated notifications with a wide number of features called CRToast.
