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:

项目内文件夹如下:

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:

原因,路径不对,到工程路径下一级一级比对,做相应的加减(不会的自行百度)
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' do
end
小Q会动的tabbar
什么是会动的tabbar呢,先看一个gif就知道了
![](http://upload-images.jianshu.io/upload_images/1723047-9a852b48b9e1f6b9.gif?imageMogr2/auto-orient/strip)
效果不炫酷,代码也很简单,之前总结过一个UIView动画 iOS 连续动画效果(让APP动起来) 实际就是用得里面的缩放动画,这次我们用一下POP实现
在podfile里面导入POP动画
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:
