前兩天iOS11正式版的推送隨之而來(lái)的是Xcode9，今年Apple搞十周年多推送一款手機(jī)--iPhoneX，雖未上市，但是這種手機(jī)屏幕對(duì)于我們開(kāi)發(fā)者來(lái)說(shuō)就有點(diǎn)不和諧了。隨著模擬器iPhone X出現(xiàn)，適配勢(shì)在必行了。不多說(shuō)了，講點(diǎn)實(shí)際的。
手頭項(xiàng)目一運(yùn)行沒(méi)有自定義navigation的地方很好，沒(méi)啥問(wèn)題但是涉及到自定義navigation的時(shí)候問(wèn)題就來(lái)了,平時(shí)喜歡隨便寫(xiě)個(gè)64的人悲劇了，我倒是平時(shí)習(xí)慣好點(diǎn)（但也只是好一點(diǎn)點(diǎn)，放在PCH文件中統(tǒng)一管理）
修改前
于是只要稍稍改一下
修改后
我特地把這些常用的放在公共的地方
//界面上面適配主要是iPhone X的狀態(tài)欄高度是44而正常是20和tabbar的高度是83（多了34），而正常的高度是49
#define StatusRectH [[UIApplication sharedApplication] statusBarFrame].size.height//狀態(tài)欄
#define NavRectH self.navigationController.navigationBar.frame.size.height////標(biāo)題欄還是44
//navi總高度(非控制器專(zhuān)用)
#define NavH_view [DRFunctionUnit getNavVC].navigationBar.frame.size.height + StatusRectH
#define VHeight (SCREEN_HEIGHT - StatusRectH - NavRectH)
#define CURRENT_SIZE(_size) _size / 320.0 * SCREEN_WIDTH
#define NavH (StatusRectH + NavRectH)
#define TabH (kDevice_Is_iPhoneX?83.f:49.f)
#define TabbarHeight (kDevice_Is_iPhoneX?83.f:49.f)
#define TabSaveHeight (kDevice_Is_iPhoneX?34.f:0)
#define kDevice_Is_iPhoneX ([UIScreen instancesRespondToSelector:@selector(currentMode)] ? CGSizeEqualToSize(CGSizeMake(1125, 2436), [[UIScreen mainScreen] currentMode].size) : NO)
眼睛尖的肯定看到了我寫(xiě)了個(gè)非控制器專(zhuān)用的navi的高度，這個(gè)主要是應(yīng)對(duì)那些你需要在項(xiàng)目中做彈出視圖（單獨(dú)拆分出來(lái)）的地方用到關(guān)于系統(tǒng)的高度，那個(gè)里面可沒(méi)有navigation，但你還是要除掉他的高度，寫(xiě)個(gè)系統(tǒng)方法就好了

UIViewController * Rootvc = [[UIApplication sharedApplication] keyWindow].rootViewController;
UITabBarController * tabVC = (UITabBarController *)Rootvc;

return nav;
