项目搭建
一、设计模式
首先呢，小Q采用传统的MVC的设计模式，优点我们再来啰嗦一下啊：1、多个视图可以对应一个模型。按MVC设计模式，一个模型对应多个视图，可以减少代码的复制及代码的维护量，一旦模型发生改变，也易于维护。2、应用被分隔为三层，降低了各层之间的耦合，提供了应用的可扩展性。3、控制层的概念也很有效，由于它把不同的模型和不同的视图组合在一起，完成不同的请求。因此，控制层可以说是包含了用户请求权限的概念。4、MVC更符合软件工程化管理的精神。不同的层各司其职，每一层的组件具有相同的特征，有利于通过工程化和工具化产生管理程序代码。转换为个人的理解就是MVC各做个的事情，把自己的工作负责好，由C来控制MV的交互，出问题了好解决，能快速找出问题点，解耦合项目目录路径如下：

好进行下一步，添加PCH文件
二、添加pch文件pch的作用：1.存放一些全局的宏(整个项目中都用得上的宏)2.用来包含一些全部的头文件(整个项目中都用得上的头文件)3.能自动打开或者关闭日志输出功能但是apple在Xcode 6中去掉了pch，为了一些琐碎的头文件引用，加快了 编译速度！习惯了pch的小伙伴们很不适应，比如我，添加方法如下：(1)创建command+n ----> PCH File(2)配置，在工程的TARGETS里边Building Setting中搜索Prefix Header，然后把Precompile Prefix Header右边的NO改为Yes、在Precompile Prefix Header下边的Prefix Header右边双击，添加刚刚创建的pch文件的工程路径，添加格式：“$(SRCROOT)/项目名称/pch文件名”
可能出现问题：

在pch文件中添加常用的宏 如下：
//16进制颜色#define UIColorFromRGB(rgbValue) [UIColor \colorWithRed:((float)((rgbValue & 0xFF0000) >> 16))/255.0 \ green:((float)((rgbValue & 0xFF00) >> 8))/255.0 \ blue:((float)(rgbValue & 0xFF))/255.0 alpha:1.0] //屏幕高度 #define SCREEN_HEIGHT [UIScreen mainScreen ].bounds.size.height //屏幕宽度 #define SCREEN_WIDTH [UIScreen mainScreen ].bounds.size.width //获取通知中心 #define LRNotificationCenter [NSNotificationCenter defaultCenter] //弱引用 #define WeakSelf(type) __weak typeof(type) weak##type = type; //强引用 #define StrongSelf(type) __strong typeof(type) type = weak##type; //GCD - 一次性执行 #define kDISPATCH_ONCE_BLOCK(onceBlock) static dispatch_once_t onceToken; dispatch_once(&onceToken, onceBlock); //GCD - 在Main线程上运行 #define kDISPATCH_MAIN_THREAD(mainQueueBlock) dispatch_async(dispatch_get_main_queue(), mainQueueBlock); //GCD - 开启异步线程 #define kDISPATCH_GLOBAL_QUEUE_DEFAULT(globalQueueBlock) dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), globalQueueBlocl);
三、cocoapods 使用
cocoapods这个大家都不陌生，怎么装怎么用都不讲了（不会的自行百度）啰嗦一点是用淘宝的Ruby镜像来访问cocoapods 这个已经不适用了，我发现了一个新的这个是可以用的，目前我用的这个
使用pod 必须要由一个podfile文件，0.X的版本和1.X的版本文件有所不一样，每次都创建一个很麻烦，一般都是拷贝一个之前有的文件全选后替换如下代码，然后install 就可以了
platform :ios, "8.1"target '项目名字' doend
小Q会动的tabbar
什么是会动的tabbar呢，先看一个gif就知道了
00000.gif
pod 'pop'
然后在终端中
pod install
在需要动画的地方加入如下代码：
POPSpringAnimation *scaleAnimation = [POPSpringAnimation animationWithPropertyNamed:kPOPViewScaleXY]; scaleAnimation.toValue = [NSValue valueWithCGPoint:CGPointMake(1, 1)]; scaleAnimation.velocity = [NSValue valueWithCGPoint:CGPointMake(10, 10)]; scaleAnimation.springBounciness = 60.f; scaleAnimation.delegate = self; [(需要动画的View） pop_addAnimation:scaleAnimation forKey:@"scaleAnimation"];
整个TabBarViewController的代码如下，很简单的东西就不做过多的讲解了：
