分辨率：
iPhoneX ：2436 * 1125 || pt: 812 * 375
iPhoneXr：1792 * 828 || pt: 896 * 414
iPhoneXs：2436 * 1125 || pt: 812 * 375
iPhoneXs Max：2688 * 1242 || pt: 896 * 414
適配：
iPhoneXs 的屏幕尺寸和iPhoneX是一樣的政冻，所以不需要做特殊處理，只需要處理適配iPhoneXr和iPhoneXs Max粱挡。
由于navBar和tabBar的高度和iPhoneX是一樣的赠幕，所以適配只需要在原來判斷iPhoneX的基礎(chǔ)上加上iPhoneXr和iPhoneXs Max的機(jī)型判斷就好了。
//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)
//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)
一些三方庫里面判斷iPhoneX基礎(chǔ)上添加iPhoneXr询筏、iPhoneXs榕堰、iPhoneXs Max的判斷：
+ (BOOL)isIphoneX {
struct utsname systemInfo;
uname(&systemInfo);
NSString *platform = [NSString stringWithCString:systemInfo.machine encoding:NSASCIIStringEncoding];
if ([platform isEqualToString:@"i386"] || [platform isEqualToString:@"x86_64"]) {
// judgment by height when in simulators
return ((CGSizeEqualToSize([UIScreen mainScreen].bounds.size, CGSizeMake(375, 812)) ||
CGSizeEqualToSize([UIScreen mainScreen].bounds.size, CGSizeMake(812, 375))) || CGSizeEqualToSize([UIScreen mainScreen].bounds.size, CGSizeMake(414, 896)) ||
CGSizeEqualToSize([UIScreen mainScreen].bounds.size, CGSizeMake(896, 414)));
}
BOOL isIPhoneX = [platform isEqualToString:@"iPhone10,3"] || [platform isEqualToString:@"iPhone10,6"] || [platform isEqualToString:@"iPhone11,2"] || [platform isEqualToString:@"iPhone11,4"] || [platform isEqualToString:@"iPhone11,6"] || [platform isEqualToString:@"iPhone11,8"];
return isIPhoneX;
}
