first game was completed, our interest in the game gradually increased. Maybe winning the work is also an encouragement for us. Then I learned about iOS game development through various channels. About a year ago, I started learning objective-C language. At this time last year, I may have just installed Mac OS and iOS SDK. I learned development in the environment. I remember that there were still many cour

The concept of responsive program
Introduction: If you read this book, you may have mastered the basics of iOS development. However, there are some minor features and practices that many developers are not familiar with, even for developers who have years of experience. In this chapter, you will learn some important development skills, but this is far from enough. You still need to accumulate more practices to make your code more powerful.

Execute the statement3. sqlite3_close function Close Database connection2) using the core data frameworkThe Core data framework is a purely object-oriented framework that allows developers to persist the SQLite database in an object-oriented manner. The core data can be persisted in the form of a SQLite database, either XML or memory.The core concept for core data is the entity, the model object managed by core data, which must be an instance of the Nsmanagedobject
Now we are in the Internet era, any software or app, will be more or less with the network, and the continuous occurrence of data interaction. An app that doesn't involve network programming will look low, and here we'll start using Swift to develop iOS apps, and primarily for network operational functions.The requirement here is to get the HTML source code for a webpage, that is, to get the data from the I

IOS Sprite Kit Tutorial Programming and Xcode Introduction Xcode interface IntroductionA Xcode project consists of a number of files, such as code files, resource files, and so on. Xcode helps developers manage these files. Therefore, Xcode's interface is also more complex, as shown in 1.40.Figure 1.40 Xcode's interfaceIn Figure 1.40, you can see that the Xcode interface can be roughly divided into 4 parts.
