Singletons in Cocoa, are they evil? - Lancy's Blog
http://gracelancy.com/blog/2013/06/04/singletons-in-cocoa-are-they-evil
Singletons in Cocoa, Are They Evil? 这事是这样的，去年我在上课的时候，和老师讨论了一下关于架构的问题，我是开发Cocoa/iOS的，老师是开发Web的，而老师是一个坚定的singletons are evil的拥护者，我和他说了我的App的架构，直接被他一顿猛劈，强烈的谴责了我使用Singletons，我回应说，这个pattern在Cocoa里是大量使用的，结果被搞了一句 用的多的就是对的么 你回去多学习一下再来讨论吧。 于是我非常郁闷的回去搜索的一大顿的资料，还在Stackoverflow上发起了一个问题 singletons in cocoa, are they evil? They are generally used as a global instance, why is that so bad? They violate the Single Responsibility Principle: by virtue of the fact that they control their own creation and lifecycle.

Variable Argument Lists - Lancy's Blog
http://gracelancy.com/blog/2014/05/05/variable-argument-lists
Variable argument lists 使用方法. 可变参数函数 Variadic Function ，即是指一个可以接受可变数量的参数的函数。 在C语言中，对该特性的支持，即是通过可变参数列表 Variable Argument list 来实现的，其定义在. 3 初始化va list，此时va list指向firstNum之后的第一个参数. Variable argument lists 的内部机制. Int %d, str %@, float %g. Format (archetype, string-index, first-to-check). NS FORMAT FUNCTION(F,A). Define NS FORMAT FUNCTION(F,A) attribute ( format( NSString , F, A) ). 备注 我们现在通常使用@[@1, @2, @3]来代替这一行代码，且不需要在最后添加nil，这称为字面量 Literals). 同format string一样危险的是，若开发者调用方法 函数 的时候，忘记在最后添加上哨兵值，则会发生不可预知的问题。
Cocoa中的位与位运算 - Lancy's Blog
http://gracelancy.com/blog/2013/09/27/bitwise-operation-in-cocoa
位操作是程序设计中对位模式或二进制数的一元和二元操作. 在许多古老的微处理器上, 位运算比加减运算略快, 通常位运算比乘除法运算要快很多. 在现代架构中, 情况并非如此:位运算的运算速度通常与加法运算相同(仍然快于乘法运算). 摘自wikipedia. C提供了6个位操作符，$， ， ， ， ，。 乘以2的m次方 n m;. 除以2的m次方 n m;. 判断奇偶 (n and 1) = 1;. 求平均数 (a b) 1;. 比如 Programming Pearls 里面的一个经典示例 如何对最多有一千万条不重复的7位整数 电话号码 进行排序 且可使用的内存空间有大约1MB多。 我们只需要使用1000万个位 大约1.2mb ，就能以集合的方式在内存里标记下所有的数据，从而轻松的实现位排序。 源码在 UIColor CYHelper.h. Turn on user interaction while animating. Start all views from current value, not initial value. If repeat, run animation back and forth.

而在 iOS 客户端开发中，MVC 作为官方推荐的主流架构，不但 SDK 已经为我们实现好了 UIView、UIViewController 等相关的组件，更是有大量的文档和范例供我们参考学习，可以说是一种非常通用而成熟的架构设计。 由于 MVC 的概念过于简单朴素，已经越来越难以适应如今客户端的需求，大量的代码逻辑在 MVC 中并没有定义得很清楚究竟应该放在什么地方，导致他们很容易就会堆积在 Controller 里，成为了人们所说的 Massive View Controller。 MVVM，Model-View-ViewModel，一个从 MVC 模式中进化而来的设计模式，最早于2005年被微软的 WPF 和 Silverlight 的架构师 John Gossman 提出。 在 iOS 开发中实践 MVVM 的话，通常会把大量原来放在 ViewController 里的视图逻辑和数据逻辑移到 ViewModel 里，从而有效的减轻了 ViewController 的负担。 MVVM 是一个年轻的设计模式，大多数人对他的了解都不如 MVC 熟悉，基于绑定机制来进行编程需要一定的学习才能较好的上手。
