iOS 判断设备型号、设备尺寸

判断型号

https://www.theiphonewiki.com/wiki/Models

Swift

var systemInfo = utsname()
uname(&systemInfo)

let machineMirror = Mirror(reflecting: systemInfo.machine)
let identifier = machineMirror.children.reduce("") { identifier, element in
    guard let value = element.value as? Int8, value != 0 else {return identifier}
    return identifier + String(UnicodeScalar(UInt8(value)))
}

OC

第一种方法

// 导入头文件
#include <sys/sysctl.h>

size_t size;
int nR = sysctlbyname("hw.machine", NULL, &size, NULL, 0);
char *machine = (char *)malloc(size);
nR = sysctlbyname("hw.machine", machine, &size, NULL, 0);
NSString *platform = [NSString stringWithCString:machine encoding:NSUTF8StringEncoding];
free(machine);

第二种方法

// 导入头文件
#include <sys/utsname.h>

struct utsname systemInfo;
uname(&systemInfo);
NSString *deviceString = [NSString stringWithCString:systemInfo.machine encoding:NSUTF8StringEncoding];

SPDeviceModels

部分代码如下，最新代码移步 github
