Afnetworking is a delightful network library made for IOS and Mac OSX , built on a URL The top layer of the loading system framework, built into the cocoa, expands the powerful advanced network abstraction. Its modular architecture is well designed and has a rich range of functions, so it is certainly pleasing to use. @ original link https://github.com/AFNetworking/AFNetworking, I based on the point configuration modification @ Introduction1.

[7 of iOS and EV3 hybrid robot programming series] EV3 and iosev3 are controlled through Bluetooth1 Preface in my previous blogs in this series, I found that without iOS jailbreak, I could not use Bluetooth to control EV3 and write a Commander-like program. However, recent studies with Netizens found that the use of External Accessory to achieve Bluetooth transmi

Grand Central Dispatch (GCD) for iOS multi-thread programming)Introduction: Grand Central Dispatch (GCD) is a technology developed by Apple to optimize applications that support multi-core processors and other systems of Symmetric Multi-processing systems. This is based on the Thread Pool Mode for concurrent task execution. It is released on Mac OS X 10.6 For the first time, and is also available for

"Animations are what bring your applications to life, and when used appropriately, they can guide your users through a course of actions,

This is a detailed tutorial on iOS block. I have searched official documents and can understand them in poor English. Slow speed. Later, I found the translation of most of the above documents and thought it was quite good. For block learning. Roughly divided into several points 1. SDK restrictions, that is, the version of the block to which the new feature is introduced. 2. Basic syntax 3. Scenario use. I. Block description Block is a new program synt

Network Programming for iOS development-1. Basic use of NSURLSession and iosnsurlsession Before learning how to use NSURLSession, I should first learn a good article about NSURLSession, From NSURLConnection to NSURLSession, or a Chinese translation From NSURLConnection to NSURLSession. alternatively, you can directly learn "from NSURLConnection to NSURLSession" without learning your blog garden notes. This

As for the network programming of iOS, we all think of the C implementation of the bottom BSD, cfnetwork and Nsurl libraries, although today a lot of third-party library is very convenient, but as a developer, also need to understand the underlying code.The following mind map is about the various protocol communication implementations used in the development of the moment.
