InWikipedia, there is an explanation:"In software engineering, the singleton pattern is a design pattern that restricts the instantiation of a class to one object." 一、什么是单例模式? 在维基百科中,是这样解释的,“在软件工程中,单例模
Singleton design patterniOSMobile applicationSoftware design patterns help structure code, solve problems and affect the design of programs by recognizing the possible abstractions in the problem. Design patterns are important technique for improving software quality since they address a fundamental challenge...
设计模式(Design pattern)是一套被反复使用、多数人知晓的、经过分类编目的、代码设计经验的总结,代表了最佳的实践, 通常被有经验的面向对象的软件开发人员所采用。 Christopher Alexander说过:“每一个模式描述了一个在我们周围不断重复发生的问题,以及该问题的解决方案的核心,这样,你就能一次又一次地使用该方案而不必...
The Singleton pattern looks like a panacea. It’s in a book on object-oriented design patterns, so it must be architecturally sound, right? And it lets us design software the way we have been doing for years.Unfortunately, it’s more placebo than cure. If you scan the list of problems...
In software engineering, the singleton pattern is a software design pattern that restricts the instantiation of a class to one "single" instance. This is useful when exactly one object is needed to coordinate actions across the system. The term comes from the mathematical concept of a singleton....

According to the book "Design Patterns, Elements of Reusable Object-Oriented Software," the Singleton design pattern ensures that a class has only one instance and provides a global point of access to it. Let's put things in simpler terms. When we say "global point of access," we convey ...
The singleton design pattern is one of the most commonly used design patterns. The singleton design pattern, just by its name, you can roughly know its meaning. Single means one; instance means instance object. So a singleton has only one instantiated object. Therefore, we can define the sing...

NOTE If singletons are a new concept to you, and you decide to search the Internet for further information, you will discover they fuel many a good argument about the design of object-oriented software. Oh yes, programmers love to argue about this stuff, and nothing stokes a dispute better...
