+## [V1.3.0](https://github.com/youngsoft/MyLinearLayout/releases/tag/1.3.0)(2016/12/21)
+
+#### Added
+1. 添加对布局位置类`MyLayoutPos`的方法:`lBound,uBound`用来设置视图的位置最小最大的依赖，`lBound，uBound`方法只有在相对布局中的子视图设置才有效。
+2. 添加了Demo:RLTest5ViewController这个例子专门用来演示相对布局中的子视图设置lBound,uBound方法的例子。
+
+#### Fixed
+1. 修复路径布局`MyPathLayout`中设置`wrapContentWidth`和`wrapContentHeight`为YES时的计算错误的情况。
+2. 修复线性布局`MyLinearLayout`里面均分间距和均分视图两个方法可能导致均分不正确的BUG。
+3. 修复了相对布局`MyRelativeLayout`中如果设置了`topPadding`而子视图的`topPos`设置为数值时`topPadding`不起作用的BUG。
+4. 修复了相对布局`MyRelativeLayout`中子视图的高度设置为`flexedHeight`时计算可能不正常的问题。
+
+#### Changed
+1. 优化了相对布局和框架布局时的性能。

+       很多同学都反馈问我：为什么要在loadView方法中进行布局而不在viewDidLoad中进行布局？ 以及在什么时候需要调用[super loadView]；什么时候不需要？现在统一回复如下：
+     
+       1.所有视图控制中的根视图view(self.view)都是在loadView中完成建立的，也就是说如果你的VC关联了XIB或者SB，那么其实会在VC的loadView方法里面加载XIB或者SB中的所有视图以及子视图，如果您的VC没有关联XIB或者SB那么loadView方法中将建立一个默认的根视图。而系统提供的viewDidLoad方法则是表示VC里面关联的视图已经建立好了，您可以有机会做其他一些初始化的东西。因此如果你想完全自定义VC里面的根视图和子视图的话那么建议您应该重载loadView方法而不是在viewDidLoad里面进行自定义视图的加载和处理。
+       2.因为MyLayout是一套基于代码的界面布局库，因此建议您从VC的根视图就使用布局视图，所以我这边的很多DEMO都是直接在loadView里面进行布局，并且把一个布局视图作为根视图赋值给self.view。因此如果您直接想把布局视图作为根视图或者想自定义根视图的实现那么您就可以不必要再loadView里面调用[super loadView]方法；而如果您只是想把布局视图作为默认根视图的一个子视图的话那么您就必须要调用[super loadView]方法，然后再通过[self.view addSubview:XXXX]来将布局视图加入到根视图里面，如果您只是想把布局视图作为根视图的一个子视图的话，那么您也完全可以不用重载loadView方法，而是直接在viewDidLoad里面添加布局视图也是一样的。
+      3.因为很多DEMO里面都是在loadView里面进行代码布局的，这个是为了方便处理，实际中布局视图是可以用在任何一个地方的，也可以在任何一个地方被建立，因此布局视图就是UIView的一个子视图，因此所有可以使用视图的地方都可以用布局视图。

     /*
       一个视图可以通过对frame的设置来完成其在父视图中的布局。这种方法的缺点是要明确的指出视图所在的位置origin和视图所在的尺寸size，而且在代码中会出现大量的常数，以及需要进行大量的计算。MyLayout的出现就是为了解决布局时的大量常数的使用，以及大量的计算，以及自动适配的问题。需要明确的是用MyLayout进行布局时并不是不要指定视图的位置和尺寸，而是可以通过一些特定的上下文来省略或者隐式的指定视图的位置和尺寸。因此不管何种布局方式，视图布局时都必须要指定视图的位置和尺寸。
