When to use(Singleton mode): When creating objects such as thread pools, caches, and so on, we can use a singleton pattern to avoid wasting resources. But if you want to store global data such as product prices, the singleton pattern becomes a reverse pattern, and you should consider replacing it with other methods. Note: The singleton has become a reverse pattern here, and we can avoid it with the following techniques: 1. Injection of dependency; 2. Use the factory

their stateWhat can be used: for example, there is a world clock program, there are multiple graphics clocks to display such as Beijing time zone, Paris time zone, and so on. If you set up a Beijing time, all other clock graphics need to be updated (plus or minus the slack value). Typical graphical interface design can be seen everywhere, a temperature program, in the temperature and humidity conditions ch

This article mainly introduces the proxy mode and abstract factory mode of Python programming.

for them. You can do it yourself by creating a singleton class that you think is necessary; for example If you had a class that provides sounds to other objects in an application, you might make it a singleton. Several Cocoa Framework classes is singletons. They include Nsfilemanager, Nsworkspace, and, in UIKit, UIApplication and Uiaccelerometer. The name of the factory method returning the singleton instance have, by convention, the form Sharedclass
