//目的:用於iOS7和iOS6適配,和保留之前的座標編碼習慣,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為ios6風格,狀態列和導航欄為平鋪 *4。bounds為ios7風格,狀態列和導航欄為覆蓋 *5。優點,所有subview的座標都一ios6的標準進行編寫,支援push和present *6。缺點,在push中每個vc都需要重寫viewDidLayoutSubviews方法; */ void IOS7ToIOS6ofFrame(UIViewController *vc); void IOS7ToIOS6ofBounds(UIViewController *vc); void IOS7ToIOS6ofFrame(UIViewController *vc) { if (IsIOS7) { CGRect rect = vc.view.frame; vc.view.frame = CGRectMake((rect.origin.x), (rect.origin.y+(IsIOS7?vc.topLayoutGuide.length:0)), (CGRectGetWidth(rect)), (CGRectGetHeight(rect)-(IsIOS7?vc.topLayoutGuide.length:0))); } } void IOS7ToIOS6ofBounds(UIViewController *vc) { if (IsIOS7) { CGRect rect = vc.view.bounds; if (rect.origin.y != -1*vc.topLayoutGuide.length) { vc.view.bounds = CGRectMake((rect.origin.x), (rect.origin.y+(IsIOS7?vc.topLayoutGuide.length*(-1):0)), (CGRectGetWidth(rect)), (CGRectGetHeight(rect))); } } } /*方法2: *1.在vc的init或viewdidload中使用IOS7巨集即可; *2.狀態列和導航欄為平鋪 *3.優點:所有subview的座標都一ios6的標準進行編寫,支援push,背景frame值同ios6 *4.缺點:在push中每個vc都需要寫,不支援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.狀態列和導航欄為平鋪 *3.優點:所有subview的座標都一ios6的標準進行編寫,支援push,背景frame值同ios6,只需要設定一次 *4.缺點:必須有nav;對於present的vc必須為nav */ /*方法4: *1.重新定義CGRECT; *2.狀態列和導航欄為覆蓋 *3.優點:隨時可以用 */ #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))
