目前常用的是通过屏幕分辨率来区分iphone设备型号（iphone4、iphone5、iphoneX等等），不过在有些时候使用这个方法判断会出现错误的结果。经过查阅资料，找到以下方法来判断，此方法是相当的靠谱！靠谱！靠谱！！！废话不多说，直接上代码：
ps：需要引入头文件：
#import "sys/utsname.h"
#import <UIKit/UIkit.h>
.h文件：
typedefNS_ENUM(NSInteger,APDeviceType) {
APDeviceIphone4 =0,//iphone4系列设备
APDeviceIphone5,//iphone5系列设备
APDeviceIphone6,//iphone6系列设备
APDeviceIphonePlus,//iphonePlus系列设备
APDeviceIphoneX,//iphoneX系列设备
APDeviceIphoneSimulator,//iphone模拟器
APDeviceIphoneOther//其他iphone系列设备
};
@interfaceKS_Tool :NSObject
//获取手机设备型号
+ (APDeviceType)currentDeviceType;
@end
.m文件：
+ (APDeviceType)currentDeviceType
{
structutsnamesystemInfo;
uname(&systemInfo);
NSString *deviceString = [NSString stringWithCString:systemInfo.machine encoding:NSUTF8StringEncoding];
if([deviceString isEqualToString:@"iPhone3,1"]) returnAPDeviceIphone4;
if([deviceString isEqualToString:@"iPhone3,2"]) returnAPDeviceIphone4;
if([deviceString isEqualToString:@"iPhone3,3"]) returnAPDeviceIphone4;
if([deviceString isEqualToString:@"iPhone4,1"]) returnAPDeviceIphone4;
if([deviceString isEqualToString:@"iPhone5,1"]) returnAPDeviceIphone5;
if([deviceString isEqualToString:@"iPhone5,2"]) returnAPDeviceIphone5;
if([deviceString isEqualToString:@"iPhone5,3"]) returnAPDeviceIphone5;
if([deviceString isEqualToString:@"iPhone5,4"]) returnAPDeviceIphone5;
if([deviceString isEqualToString:@"iPhone6,1"]) returnAPDeviceIphone5;
if([deviceString isEqualToString:@"iPhone6,2"]) returnAPDeviceIphone5;
if([deviceString isEqualToString:@"iPhone7,1"]) returnAPDeviceIphonePlus;
if([deviceString isEqualToString:@"iPhone7,2"]) returnAPDeviceIphone6;
if([deviceString isEqualToString:@"iPhone8,1"]) returnAPDeviceIphone6;
if([deviceString isEqualToString:@"iPhone8,2"]) returnAPDeviceIphonePlus;
if([deviceString isEqualToString:@"iPhone8,4"]) returnAPDeviceIphone5;
if([deviceString isEqualToString:@"iPhone9,1"]) returnAPDeviceIphone6;
if([deviceString isEqualToString:@"iPhone9,2"]) returnAPDeviceIphonePlus;
if([deviceString isEqualToString:@"iPhone9,3"]) returnAPDeviceIphone6;
if([deviceString isEqualToString:@"iPhone9,4"]) returnAPDeviceIphonePlus;
if([deviceString isEqualToString:@"iPhone10,1"]) returnAPDeviceIphone6;
if([deviceString isEqualToString:@"iPhone10,4"]) returnAPDeviceIphone6;
if([deviceString isEqualToString:@"iPhone10,2"]) returnAPDeviceIphonePlus;
if([deviceString isEqualToString:@"iPhone10,5"]) returnAPDeviceIphone6;
if([deviceString isEqualToString:@"iPhone10,3"]) returnAPDeviceIphoneX;
if([deviceString isEqualToString:@"iPhone10,6"]) returnAPDeviceIphoneX;
if([deviceString isEqualToString:@"x86_64"] || [deviceStringisEqualToString:@"i386"]) {
if ([UIScreen instancesRespondToSelector:@selector(currentMode)] ? CGSizeEqualToSize(CGSizeMake(640, 1136), [[UIScreen mainScreen] currentMode].size) : NO) {
return APDeviceIphone5;
}else if ([UIScreen instancesRespondToSelector:@selector(currentMode)] ? CGSizeEqualToSize(CGSizeMake(750, 1334), [[UIScreen mainScreen] currentMode].size) : NO) {
return APDeviceIphone6;
}else if ([UIScreen instancesRespondToSelector:@selector(currentMode)] ? (CGSizeEqualToSize(CGSizeMake(1125, 2001), [[UIScreen mainScreen] currentMode].size)
||CGSizeEqualToSize(CGSizeMake(1242,2208), [[UIScreenmainScreen]currentMode].size)) :NO) {
return APDeviceIphonePlus;
}else if ([UIScreen instancesRespondToSelector:@selector(currentMode)] ? CGSizeEqualToSize(CGSizeMake(1125, 2436), [[UIScreen mainScreen] currentMode].size) : NO) {
return APDeviceIphoneX;
}else{
return APDeviceIphoneOther;
}
}
return APDeviceIphoneOther;
}
通过deviceString变量，还可以判断出对应的iPad设备，此处就不一一列举了。。。
