由上圖可見 iPhoneXs 的屏幕尺寸和去年的iPhoneX是一樣的切省，所以今年不需要做特殊處理良蛮。
主要處理下后面的兩款新的尺寸機型：
去年適配的iPhoneX 的分辨率：2436 * 1125 || pt: 812 * 375
iPhoneXr的分辨率：1792 * 828 || pt: 896 * 414
iPhoneXs 的分辨率： 2436 * 1125 || pt: 812 * 375
iPhoneXs Max 的分辨率：2688 * 1242 || pt: 896 * 414
導航欄和tabBar的高度是一樣的，所以需要在原來判斷iPhoneX的基礎上增加兩種機型.
//判斷是否是ipad
#define isPad ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPad)
//判斷iPhone4系列
#define kiPhone4 ([UIScreen instancesRespondToSelector:@selector(currentMode)] ? CGSizeEqualToSize(CGSizeMake(640, 960), [[UIScreen mainScreen] currentMode].size) && !isPad : NO)
//判斷iPhone5系列
#define kiPhone5 ([UIScreen instancesRespondToSelector:@selector(currentMode)] ? CGSizeEqualToSize(CGSizeMake(640, 1136), [[UIScreen mainScreen] currentMode].size) && !isPad : NO)
//判斷iPhone6系列
#define kiPhone6 ([UIScreen instancesRespondToSelector:@selector(currentMode)] ? CGSizeEqualToSize(CGSizeMake(750, 1334), [[UIScreen mainScreen] currentMode].size) && !isPad : NO)
//判斷iphone6+系列
#define kiPhone6Plus ([UIScreen instancesRespondToSelector:@selector(currentMode)] ? CGSizeEqualToSize(CGSizeMake(1242, 2208), [[UIScreen mainScreen] currentMode].size) && !isPad : NO)
//判斷iPhoneX
#define IS_IPHONE_X ([UIScreen instancesRespondToSelector:@selector(currentMode)] ? CGSizeEqualToSize(CGSizeMake(1125, 2436), [[UIScreen mainScreen] currentMode].size) && !isPad : NO)
//判斷iPHoneXr
#define IS_IPHONE_Xr ([UIScreen instancesRespondToSelector:@selector(currentMode)] ? CGSizeEqualToSize(CGSizeMake(828, 1792), [[UIScreen mainScreen] currentMode].size) && !isPad : NO)
//判斷iPhoneXs
#define IS_IPHONE_Xs ([UIScreen instancesRespondToSelector:@selector(currentMode)] ? CGSizeEqualToSize(CGSizeMake(1125, 2436), [[UIScreen mainScreen] currentMode].size) && !isPad : NO)
//判斷iPhoneXs Max
#define IS_IPHONE_Xs_Max ([UIScreen instancesRespondToSelector:@selector(currentMode)] ? CGSizeEqualToSize(CGSizeMake(1242, 2688), [[UIScreen mainScreen] currentMode].size) && !isPad : NO)
navBar和tabBar的判斷
//iPhoneX系列
#define Height_StatusBar ((IS_IPHONE_X==YES || IS_IPHONE_Xr ==YES || IS_IPHONE_Xs== YES || IS_IPHONE_Xs_Max== YES) ? 44.0 : 20.0)
#define Height_NavBar ((IS_IPHONE_X==YES || IS_IPHONE_Xr ==YES || IS_IPHONE_Xs== YES || IS_IPHONE_Xs_Max== YES) ? 88.0 : 64.0)
#define Height_TabBar ((IS_IPHONE_X==YES || IS_IPHONE_Xr ==YES || IS_IPHONE_Xs== YES || IS_IPHONE_Xs_Max== YES) ? 83.0 : 49.0)
