iOS7和iOS6適配

//目的:用於iOS7和iOS6適配,和保留以前的座標編碼習慣,不用刻意加減
 
/*方法1:
 *1。在vc中重寫viewDidLayoutSubviews方法
 *2。是用下面2個方法之一;
 *3。frame爲ios6風格,狀態欄和導航欄爲平鋪
 *4。bounds爲ios7風格,狀態欄和導航欄爲覆蓋
 *5。優勢,全部subview的座標都一ios6的標準進行編寫,支持push和present
 *6。缺點,在push中每一個vc都須要重寫viewDidLayoutSubviews方法;
 */

    if (IsIOS7) {

        }
    }
}
 
/*方法2:
 *1.在vc的init或viewdidload中使用IOS7宏便可;
 *2.狀態欄和導航欄爲平鋪
 *3.優勢:全部subview的座標都一ios6的標準進行編寫,支持push,背景frame值同ios6
 *4.缺點:在push中每一個vc都須要寫,不支持present;
 */
 
#define IOS7 if([[[[UIDevice currentDevice] systemVersion] substringToIndex:1] intValue]>=7)\
{self.extendedLayoutIncludesOpaqueBars = NO;\
self.modalPresentationCapturesStatusBarAppearance =NO;\
self.edgesForExtendedLayout = UIRectEdgeNone;}
 
/*方法3:
 *1.使用self.navigationController.navigationBar.translucent =NO;
 *2.狀態欄和導航欄爲平鋪
 *3.優勢:全部subview的座標都一ios6的標準進行編寫,支持push,背景frame值同ios6,只須要設置一次
 *4.缺點:必須有nav;對於present的vc必須爲nav
 */
 
/*方法4:
 *1.從新定義CGRECT;
 *2.狀態欄和導航欄爲覆蓋
 *3.優勢:隨時能夠用
 */
#define IsIOS7 ([[[[UIDevice currentDevice] systemVersion] substringToIndex:1] intValue]>=7)
#define CGRECT_NO_NAV(x,y,w,h) CGRectMake((x), (y+(IsIOS7?20:0)), (w), (h))
#define CGRECT_HAVE_NAV(x,y,w,h) CGRectMake((x), (y+(IsIOS7?64:0)), (w), (h))
