iOS7和iOS6适配

//目的：用于iOS7和iOS6适配，和保留之前的坐标编码习惯，不用刻意加减
 
/*方法1：
 *1。在vc中重写viewDidLayoutSubviews方法
 *2。是用下面2个方法之一；
 *3。frame为ios6风格，状态栏和导航栏为平铺
 *4。bounds为ios7风格，状态栏和导航栏为覆盖
 *5。优点，所有subview的坐标都一ios6的标准进行编写，支持push和present
 *6。缺点，在push中每个vc都需要重写viewDidLayoutSubviews方法；

/*方法2:
 *1.在vc的init或viewdidload中使用IOS7宏即可；
 *2.状态栏和导航栏为平铺
 *3.优点：所有subview的坐标都一ios6的标准进行编写，支持push，背景frame值同ios6
 *4.缺点：在push中每个vc都需要写，不支持present；

self.edgesForExtendedLayout = UIRectEdgeNone;}
 
/*方法3:
 *1.使用self.navigationController.navigationBar.translucent =NO;
 *2.状态栏和导航栏为平铺
 *3.优点：所有subview的坐标都一ios6的标准进行编写，支持push，背景frame值同ios6，只需要设置一次
 *4.缺点：必须有nav；对于present的vc必须为nav
 */
 
/*方法4:
 *1.重新定义CGRECT;
 *2.状态栏和导航栏为覆盖
 *3.优点：随时可以用
