}
记得一定要#import啊
Swift代码获取iOS设备型号：
//MARK: - UIDevice延展
public extension UIDevice {
var modelName: String {
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 where value != 0 else { return identifier }
return identifier + String(UnicodeScalar(UInt8(value)))
}
switch identifier {
case "iPod5,1": return "iPod Touch 5"
case "iPod7,1": return "iPod Touch 6"
case "iPhone3,1", "iPhone3,2", "iPhone3,3": return "iPhone 4"
case "iPhone4,1": return "iPhone 4s"
case "iPhone5,1", "iPhone5,2": return "iPhone 5"
case "iPhone5,3", "iPhone5,4": return "iPhone 5c"
case "iPhone6,1", "iPhone6,2": return "iPhone 5s"
case "iPhone7,2": return "iPhone 6"
case "iPhone7,1": return "iPhone 6 Plus"

case "iPhone8,2": return "iPhone 6s Plus"
case "iPhone9,1": return "iPhone 7 (CDMA)"
case "iPhone9,3": return "iPhone 7 (GSM)"
case "iPhone9,2": return "iPhone 7 Plus (CDMA)"
case "iPhone9,4": return "iPhone 7 Plus (GSM)"
case "iPad2,1", "iPad2,2", "iPad2,3", "iPad2,4":return "iPad 2"

case "AppleTV5,3": return "Apple TV"
case "i386", "x86_64": return "Simulator"
default: return identifier
}
}
}
(三)其他设备信息查询(不经常用)
- (void)deviceInfo {
UIDevice *dev = [UIDevice currentDevice];
NSLog(@"是否支持多任务：%@", dev.multitaskingSupported?@"是":@"否");
NSLog(@"设备名字：%@", dev.name);
NSLog(@"系统名字：%@", dev.systemName);
NSLog(@"设备model：%@", dev.model);
NSLog(@"设备本地化model：%@", dev.localizedModel);
NSLog(@"用户界面类型：%ld", (long)dev.userInterfaceIdiom);
NSLog(@"设备厂商标识：%@", dev.identifierForVendor);
NSLog(@"设备方向：%ld", (long)dev.orientation);
NSLog(@"是否可以生成设备方向通知：%@", dev.generatesDeviceOrientationNotifications?@"是":@"否");
NSLog(@"设备电量：%f", dev.batteryLevel);
NSLog(@"电量监测是否启用：%@", dev.batteryMonitoringEnabled?@"是":@"否");
NSLog(@"设备电量状态：%ld", (long)dev.batteryState);
NSLog(@"距离感应器是否可以使用：%@", dev.proximityMonitoringEnabled?@"是":@"否");
NSLog(@"距离感应器是否打开：%@", dev.proximityState?@"是":@"否");
}
6.获取设备电池状态
- OC代码
/**
获取手机电池状态
@return 电池状态字符串
*/
- (NSString *)getiPhoneBatteryState
{
//设置batteryMonitoringEnabled为YES来获取电池信息
[UIDevice currentDevice].batteryMonitoringEnabled = YES;
UIDeviceBatteryState phoneBatteryState = [[UIDevice currentDevice] batteryState];
NSString *state;
switch (phoneBatteryState) {
case UIDeviceBatteryStateUnknown:
state = @"未知电池状态";
break;
case UIDeviceBatteryStateUnplugged:
state = @"未充电，使用电池";
break;
case UIDeviceBatteryStateCharging:
state = @"充电中，并且电量小于 100%";
break;
case UIDeviceBatteryStateFull:
state = @"充电中, 电量已达 100%";
break;
default:
state = @"未知电池状态";
break;
}
return state;
}
7.获取设备电量
- OC代码
//设置batteryMonitoringEnabled为YES来获取电池信息
[UIDevice currentDevice].batteryMonitoringEnabled = YES;
//电池百分比
CGFloat batteryLevel = [[UIDevice currentDevice] batteryLevel];
NSString *iPhoneBattery = [NSString stringWithFormat:@"%0.0f%%",batteryLevel*100];
8.获取设备网络状态
我这里使用的苹果官方推荐的Reachability。所以要获取网络状态的朋友需要去下载Reachability的文件。由于我个人改了Reachability中的方法。所以Reachability文件的名称被我改成了HYJCrashReachability。这里大家看看调用过程即可。过程是一样的。
- OC代码
#pragma mark - 获取网络状态
/**
!@biref 获取当前设备网络状态
@return NSString类型的状态值（无网络,2G,3G,4G,WIFT）
*/
- (NSString *)getNetWorkStates{
HYJCrashReachability *reachability = [HYJCrashReachability reachabilityWithHostName:@"www.apple.com"];
NetworkStatus internetStatus = [reachability currentReachabilityStatus];
NSString *net = @"wifi";
switch (internetStatus) {
case HYJCrashReachableViaWiFi:
net = @"wifi";
break;
case HYJCrashkRaeachableVia4G:
net = @"4G";
break;
case HYJCrashkReachableVia2G:
net = @"2G";
break;
case HYJCrashkReachableVia3G:
net = @"3G";
break;
case HYJCrashNotReachable:
net = @"notReachable";
break;
default:
net = @"unknown";
break;
}
return net;
}
9.获取网络运营商
需要导入
import <CoreTelephony/CTTelephonyNetworkInfo.h>
import <CoreTelephony/CTCarrier.h>
- OC代码
#pragma mark - 获取网络运营商
/**
!@biref 获取网络运营商
@return NSString类型的运营商信息
*/
- (NSString *)getCarrierName{
CTTelephonyNetworkInfo *telephonyInfo = [[CTTelephonyNetworkInfo alloc] init];
CTCarrier *carrier = [telephonyInfo subscriberCellularProvider];
NSString *currentCountry=[carrier carrierName];
return currentCountry;
}
10.获取IP地址
由于真实Mac地址是获取不到的，这属于用户隐私。这里获取到的地址并不准确。可能会因为路由转换而改变。
需要导入
import <net/if.h>
import <ifaddrs.h>
import <arpa/inet.h>
- OC代码
#pragma mark - 获取IP地址
/**
!@biref 获取IP地址，YES表示获取IPv4,NO表示获取IPv6
@return NSString类型的ip地址
*/
- (NSString *)getIPAddress:(BOOL)preferIPv4
{
NSArray *searchArray = preferIPv4 ?
@[ HYJCrash_IOS_VPN @"/" HYJCrash_IP_ADDR_IPv4, HYJCrash_IOS_VPN @"/" HYJCrash_IP_ADDR_IPv6, HYJCrash_IOS_WIFI @"/" HYJCrash_IP_ADDR_IPv4, HYJCrash_IOS_WIFI @"/" HYJCrash_IP_ADDR_IPv6, HYJCrash_IOS_CELLULAR @"/" HYJCrash_IP_ADDR_IPv4, HYJCrash_IOS_CELLULAR @"/" HYJCrash_IP_ADDR_IPv6 ] :
@[ HYJCrash_IOS_VPN @"/" HYJCrash_IP_ADDR_IPv6, HYJCrash_IOS_VPN @"/" HYJCrash_IP_ADDR_IPv4, HYJCrash_IOS_WIFI @"/" HYJCrash_IP_ADDR_IPv6, HYJCrash_IOS_WIFI @"/" HYJCrash_IP_ADDR_IPv4, HYJCrash_IOS_CELLULAR @"/" HYJCrash_IP_ADDR_IPv6, HYJCrash_IOS_CELLULAR @"/" HYJCrash_IP_ADDR_IPv4 ] ;
NSDictionary *addresses = [self getIPAddresses];
__block NSString *address;
[searchArray enumerateObjectsUsingBlock:^(NSString *key, NSUInteger idx, BOOL *stop)
{
address = addresses[key];
if(address) *stop = YES;
} ];
return address ? address : @"1.1.1.1";
}
- (NSDictionary *)getIPAddresses
{
NSMutableDictionary *addresses = [NSMutableDictionary dictionaryWithCapacity:8];
// retrieve the current interfaces - returns 0 on success
struct ifaddrs *interfaces;
if(!getifaddrs(&interfaces)) {
// Loop through linked list of interfaces
struct ifaddrs *interface;
for(interface=interfaces; interface; interface=interface->ifa_next) {
if(!(interface->ifa_flags & IFF_UP) /* || (interface->ifa_flags & IFF_LOOPBACK) */ ) {
continue; // deeply nested code harder to read
}
const struct sockaddr_in *addr = (const struct sockaddr_in*)interface->ifa_addr;
char addrBuf[ MAX(INET_ADDRSTRLEN, INET6_ADDRSTRLEN) ];
if(addr && (addr->sin_family==AF_INET || addr->sin_family==AF_INET6)) {
NSString *name = [NSString stringWithUTF8String:interface->ifa_name];
NSString *type;
if(addr->sin_family == AF_INET) {
if(inet_ntop(AF_INET, &addr->sin_addr, addrBuf, INET_ADDRSTRLEN)) {
type = HYJCrash_IP_ADDR_IPv4;
}
} else {
const struct sockaddr_in6 *addr6 = (const struct sockaddr_in6*)interface->ifa_addr;
if(inet_ntop(AF_INET6, &addr6->sin6_addr, addrBuf, INET6_ADDRSTRLEN)) {
type = HYJCrash_IP_ADDR_IPv6;
}
}
if(type) {
NSString *key = [NSString stringWithFormat:@"%@/%@", name, type];
addresses[key] = [NSString stringWithUTF8String:addrBuf];
}
}
}
// Free memory
freeifaddrs(interfaces);
}
return [addresses count] ? addresses : nil;
}
11.获取设备当前可用内存大小
需要导入
include <mach/mach_host.h>
- OC代码
#pragma mark - 获取当前可用内存
/**
获取当前可用内存
@return 当前可用内存大小
*/
-(long long)getAvailableMemorySize
{
vm_statistics_data_t vmStats;
mach_msg_type_number_t infoCount = HOST_VM_INFO_COUNT;
kern_return_t kernReturn = host_statistics(mach_host_self(), HOST_VM_INFO, (host_info_t)&vmStats, &infoCount);
if (kernReturn != KERN_SUCCESS)
{
return NSNotFound;
}
return ((vm_page_size * vmStats.free_count + vm_page_size * vmStats.inactive_count));
}
12.获取设备当前已使用内存大小
需要导入
include <mach/task.h>//获取已用内存大小
- OC代码
#pragma mark - 获取已使用内存大小
/**
获取已使用内存大小
@return 已使用内存大小
*/
- (double)getUsedMemory
{
task_basic_info_data_t taskInfo;
mach_msg_type_number_t infoCount = TASK_BASIC_INFO_COUNT;
kern_return_t kernReturn = task_info(mach_task_self(),
TASK_BASIC_INFO,
(task_info_t)&taskInfo,
&infoCount);
if (kernReturn != KERN_SUCCESS
) {
return NSNotFound;
}
return taskInfo.resident_size;
}
13.获取设备的磁盘大小
这里磁盘容量说明下，计算机是按照1024来计算的而一般媒体设备计量是按照1000。也就是说计算机 1KB = 1024.而苹果官网说的手机内存64G，256G。是按照媒体设备计量来的，1KB = 1000
- OC代码
#pragma mark - 获取磁盘容量
/**
获取磁盘容量
@return 磁盘容量
*/
-(long long)getTotalDiskSize
{
struct statfs buf;
unsigned long long freeSpace = -1;
if (statfs("/var", &buf) >= 0)
{
freeSpace = (unsigned long long)(buf.f_bsize * buf.f_blocks);
}
return freeSpace;
}
14.获取设备当前可用的磁盘容量大小
- OC代码
#pragma mark - 获取可用磁盘容量
/**
获取可用磁盘容量
@return 可用磁盘容量
*/
-(long long)getAvailableDiskSize
{
struct statfs buf;
unsigned long long freeSpace = -1;
if (statfs("/var", &buf) >= 0)
{
freeSpace = (unsigned long long)(buf.f_bsize * buf.f_bavail);
}
return freeSpace;
}
