I. Thread creation:Operation objectis may create threads faster. For details, refer to: iOS core system programming best practices: concurrency.1. Thread creation requires a large amount of memory and time consumption. Therefore, we recommend that you use the entry point function to do a considerable amount of work, or create a Run Loops to allow regular work.2. Run Loops allows you to create long-running t

Network Programming for iOS development-using NSURLConnection for file upload and iosnsurlconnection Using NSURLConnection to upload files is cumbersome. This document does not introduce the use of third-party frameworks to upload files. Body: Here we first provide the interface for encoding testing: http: // 120.25.226.186: 32812 click in and you will find the following: It is best to use the Google

In the previous article, "iOS from the zero-learning socket programming--http1.0 Client" has simply introduced socket programming and some basic principles. and implemented a simple iOS client (original address: http://blog.csdn.net/abc649395594/article/details/45081567)Here is a brief introduction to how to use OC to

Program Design Language Objective-C is a simple and object-oriented programming language that is used by all IOS applications. You need to write objective-CCodeTo create an application, and you need to understand the language to use most of the frameworks. Although you can use otherProgramming LanguageBut IOS applications cannot be generated without objective-C.

Each IOS application has a main thread that is designed to update the UI interface and handle the user's touch events, so it is not possible to put other too-time-consuming operations on the main thread, or it will cause the main thread to clog (the phenomenon of card-machine), resulting in a very bad user experience. The general solution is to put those time-consuming operations into another thread to execute, multithreading is the best way to preven

This article summarizes the methods used for HTTP communication and data upload and download in iOS development. There are third-party class libraries commonly used in network programming afnetworking or IOS7 start a new nsurlsession, and Nsurlsession's predecessor Nsurlconnection. In general, the use of afnetworking can satisfy most requirements and is more concise and efficient.Post and get of 1.HTTP prot

can cause compilation errors, and you need to reference quartzcore.framework in your project as well.Method Three: Manage third parties with CocoapodsWhen you develop an iOS app, you'll often use many third-party open source libraries, such as jsonkit,afnetworking and more. Maybe a class library to use other class libraries, so to use it, you have to have to download another class library, and other class libraries to use other class libraries, "The
