Design Patterns A design pattern solves a common software engineering problem. Patterns are abstract designs, not code. When you adopt a design, you adapt the general pattern to your specific needs. 设计模式解决了一个通用的软件工程问题. 模式是抽象的设计,不是代码.当你采用一个模式,就是让通用模式适…
App Design Apps do not exist on their own. They not only interact seamlessly with their environment, they also leverage the features that OS X has to offer. Users expect your app to behave the same as the system-supplied apps such as Mail, Calendar,…
