IOS Game Development Cookbook, ioscookbook "/>Book Description Want to build games with iOS technologies? This cookbook provides detailed recipes for a wide range of common iOS game-development issues, ranging from 2D and 3D math to Game Center integration, and OpenGL to performance. if you're familiar with iOS and Objective-C, this is the problem-solving guide you want. Rather than focus on specific game

Python cookbook (data structures and algorithms) keeps the dictionary orderly. This example describes how to keep the dictionary in order by using Python. We will share this with you for your reference. The details are as follows: Problem:When creating a dictionary and performing iteration or serialization operations on the dictionary, you can also control the order of its elements; Solution:You can use the OrderedDict class in the collections module

Python cookbook (data structure and algorithm) is used to break down elements from any length of iteratable objects. This example describes how to use python to break down elements from iteratable objects of any length. We will share this with you for your reference. The details are as follows: N elements are extracted from an Iterated object, but the length of the iterated object may exceed N, resulting in an exception of "too many decomposition valu

Yesterday when shopping to see the peace bird inside put a metal Mickey Mouse, so the occupational disease committed, has been thinking about the color of metal is what, this reflection how to write, think not come out ...Today just see the dynamic Reflection Cubic chart System This section, after reading feel very awkward, because the book is introduced in advance casing generate cubemap way instead of real-time. Then to the official documents to find real-time reflection of the code, did a mor

Python cookbook (data structure and algorithm) uses a public key to sort the dictionary list. This example describes how to sort the dictionary list by using public keys in Python. We will share this with you for your reference. The details are as follows: Problem:Sort the list by values in one or more dictionaries. Solution:In the operator moduleitemgetter()The function is very simple to sort such structures. # Sort a list of a dicts on a common keyr

Python cookbook (data structure and algorithm) is used to filter and extract elements in a sequence. This article describes how to filter and extract elements in a sequence using Python. We will share this with you for your reference. The details are as follows: Problem:Extracts values from a sequence or deletes the sequence according to certain criteria. Solution:List derivation, generator expression, use built-infilter()Function 1. List derivation m

[C #] Concurrency in C # Cookbook (1)-concurrent programming overview,Concurrent Programming Overview We often hear in our ears about terms such as high performance, concurrency, and parallelism, and many people have some misunderstandings about concurrent programming.

Powerful SQL: SQL Cookbook Reading Notes 1-sorting the mixed data of letters and numbers recently, I am reading a really good book on SQL Cookbook. Many solutions are very subtle, I really realized that SQL is powerful. Note: I use ORACLE 11g and Below is an example in book 2.4 -- Sort the data sequence of mixed letters and numbers. First, we need a table emp in the book, the table creation file or statemen

Parsing and traversing documentsParsing HTML documents:String html = "+ "Document doc = jsoup.parse (HTML);The parser parses the HTML file as much as possible, regardless of whether the HTML file is well-formed. It can be handled very well:(1) Non-finished labels (e.g. (2) Unspecified label (for example: Packaging (3) Create a document structure reliably (contains a head and a body of HTML, only the appropriate elements in the head)Object model of the documentThe document contains elements and T

In the daily Java code development process, it is inevitable to have multi-threaded requirements, mastering the Java multithreading and concurrency mechanism is the Java programmer to write more robust and efficient code base. I find the domestic published on the Java Multi-threading and concurrency of Chinese books and translation books, we unanimously recommended is "Java Concurrency in practice", the author has not read the original English, I look at its translation version of "Java Concurre

Book Description “About a year ago, noticing that Apple had not updated Objective-C much over the past few years, I got intimations that they were working on a new language or framework for iOS development, and even suggested it to my friends at work. They laughed and said, “Then you will have to write your book from scratch.” They were right; this edition is almost a whole new book”Excerpt From: Vandad Nahavandipoor. “iOS 8 Swift Programming Cookbook
