ios 获取序列号

可以通过以下代码获取iOS设备的序列号：

NSString *serialNumber = nil;
CFTypeRef serialNumberRef = IORegistryEntryCreateCFProperty(
    IORegistryEntryFromPath(kIOMasterPortDefault, "IOService:/IOResources/IOPlatformExpertDevice"),
    CFSTR("IOPlatformSerialNumber"), kCFAllocatorDefault, 0);
if (serialNumberRef) {
    serialNumber = CFBridgingRelease(serialNumberRef);
}

这里使用了`IORegistryEntryCreateCFProperty`函数和`IORegistryEntryFromPath`函数来获取设备的序列号。需要注意的是，这个序列号是硬件固定的，不会随设备恢复出厂设置而改变。但是在某些情况下，设备序列号可能会被篡改或伪造，因此不能完全依赖它作为设备的唯一标识符。

NSString* getDeviceSerialNumber() {
    UIDevice *device = [UIDevice currentDevice];
    NSString *deviceSerialNumber = nil;

    if ([device respondsToSelector:@selector(identifierForVendor)]) {
        deviceSerialNumber = [[device identifierForVendor] UUIDString];
    } else {
        deviceSerialNumber = (NSString*)CFBridgingRelease(CFUUIDCreateString(NULL, CFUUIDCreate(NULL)));
    }

    return deviceSerialNumber;
}

其中，`getDeviceSerialNumber` 返回的是设备的唯一标识符，可以用作设备的序列号。

ios获取imei

在iOS设备上，无法直接获取IMEI号码。因为苹果公司禁止开发者访问设备的IMEI号码。

但是可以通过以下方式获取类似的设备唯一标识符：

1. 获取设备的UUID

NSString *identifier = [[[UIDevice currentDevice] identifierForVendor] UUIDString];

2. 获取设备的序列号

NSString *serialNumber = [[[UIDevice currentDevice] identifierForVendor] UUIDString];

这两个值都可以作为设备的唯一标识符来使用。需要注意的是，这些标识符在设备恢复出厂设置后会发生变化。
