iOS12.4之前判斷iPhoneXR的宏是沒(méi)有問(wèn)題的，但是升級(jí)到12.4后發(fā)現(xiàn)判斷方法已經(jīng)失效了，尺寸不再是828 x 1792 而是 750 x 1624 所以將iPhoneXR的判斷方式修改一下：

//修改后的iPhoneXR的判斷宏
#define IS_IPHONE_Xr  ([UIScreen instancesRespondToSelector:@selector(currentMode)] ? CGSizeEqualToSize(CGSizeMake(828, 1792), [[UIScreen mainScreen] currentMode].size) : NO) || ([UIScreen instancesRespondToSelector:@selector(currentMode)] ? CGSizeEqualToSize(CGSizeMake(750, 1624), [[UIScreen mainScreen] currentMode].size) : NO)
