iOS常用系统信息获取方法
一、手机电量获取，方法二需要导入头文件#import<objc/runtime.h>
方法一、获取电池电量(一般用百分数表示,大家自行处理就好）
-(CGFloat)getBatteryQuantity
{
return [[UIDevice currentDevice] batteryLevel];
}
方法二、
- (int)getCurrentBatteryLevel
{
UIApplication *app = [UIApplication sharedApplication];
if (app.applicationState == UIApplicationStateActive||
app.applicationState==UIApplicationStateInactive)
{
Ivar ivar= class_getInstanceVariable([app class],"_statusBar");
id status = object_getIvar(app, ivar);
for (id aview in [status subviews])
{
int batteryLevel = ;
for (id bview in [aview subviews])
{
if ([NSStringFromClass([bview class]) caseInsensitiveCompare:@"UIStatusBarBatteryItemView"]
== NSOrderedSame&&[[[UIDevice currentDevice] systemVersion] floatValue] >=6.0)
{ Ivar ivar = class_getInstanceVariable([bview class],"_capacity");
if(ivar)
{
batteryLevel = ((int (*)(id, Ivar))object_getIvar)(bview, ivar);
//这种方式也可以
/*ptrdiff_t offset = ivar_getOffset(ivar);
unsigned char *stuffBytes = (unsigned char *)(__bridge void *)bview;
batteryLevel = * ((int *)(stuffBytes + offset));*/
if (batteryLevel > && batteryLevel <= ){
return batteryLevel;
}
else{
return ;
}
}
}
}
}
}
return ;
}
二、获取手机电池状态（UIDeviceBatteryState为枚举类型）
// UIDeviceBatteryStateUnknown：无法取得充电状态情况
// UIDeviceBatteryStateUnplugged：非充电状态
// UIDeviceBatteryStateCharging：充电状态
// UIDeviceBatteryStateFull：充满状态（连接充电器充满状态） -(UIDeviceBatteryState)getBatteryStauts
{
UIDevice *device = [UIDevice currentDevice];
device.batteryMonitoringEnabled = YES;
return device.batteryState;
}
三、获取手机总运行内存大小
//3.获取总内存大小
-(NSString *)getTotalMemorySize
{
return [self fileSizeToString:[NSProcessInfo processInfo].physicalMemory];
} -(NSString *)fileSizeToString:(unsigned long long)fileSize
{
NSInteger KB = ;
NSInteger MB = KB*KB;
NSInteger GB = MB*KB; if (fileSize < ) {
return @"0 B";
}else if (fileSize < KB) {
return @"< 1 KB";
}else if (fileSize < MB) {
return [NSString stringWithFormat:@"%.1f KB",((CGFloat)fileSize)/KB];
}else if (fileSize < GB) {
return [NSString stringWithFormat:@"%.1f MB",((CGFloat)fileSize)/MB];
}else {
return [NSString stringWithFormat:@"%.1f GB",((CGFloat)fileSize)/GB];
}
}
四、获取当前剩余内存和已用内存，需要添加头文件#import <sys/sysctl.h> 和#import <mach/mach.h>
// 获取当前设备可用内存(单位：MB）
- (double)availableMemory
{
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) / 1024.0) / 1024.0;
} // 获取当前任务所占用的内存（单位：MB）
- (double)usedMemory
{
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 / 1024.0 / 1024.0;
}
五、获取手机型号，需要添加头文件#import<sys/utsname.h>
+ (NSString *)getCurrentiPhoneType
{
struct utsname systemInfo;
uname(&systemInfo);
NSString *platform = [NSString stringWithCString:systemInfo.machine encoding:NSASCIIStringEncoding]; if ([platform isEqualToString:@"iPhone1,1"]) return @"iPhone 2G"; if ([platform isEqualToString:@"iPhone1,2"]) return @"iPhone 3G"; if ([platform isEqualToString:@"iPhone2,1"]) return @"iPhone 3GS"; if ([platform isEqualToString:@"iPhone3,1"]) return @"iPhone 4"; if ([platform isEqualToString:@"iPhone3,2"]) return @"iPhone 4"; if ([platform isEqualToString:@"iPhone3,3"]) return @"iPhone 4"; if ([platform isEqualToString:@"iPhone4,1"]) return @"iPhone 4S"; if ([platform isEqualToString:@"iPhone5,1"]) return @"iPhone 5"; if ([platform isEqualToString:@"iPhone5,2"]) return @"iPhone 5"; if ([platform isEqualToString:@"iPhone5,3"]) return @"iPhone 5c"; if ([platform isEqualToString:@"iPhone5,4"]) return @"iPhone 5c"; if ([platform isEqualToString:@"iPhone6,1"]) return @"iPhone 5s"; if ([platform isEqualToString:@"iPhone6,2"]) return @"iPhone 5s"; if ([platform isEqualToString:@"iPhone7,1"]) return @"iPhone 6 Plus"; if ([platform isEqualToString:@"iPhone7,2"]) return @"iPhone 6"; if ([platform isEqualToString:@"iPhone8,1"]) return @"iPhone 6s"; if ([platform isEqualToString:@"iPhone8,2"]) return @"iPhone 6s Plus"; if([platform isEqualToString:@"iPhone8,4"]) return@"iPhone SE"; if([platform isEqualToString:@"iPhone9,1"]) return@"iPhone 7"; if([platform isEqualToString:@"iPhone9,2"]) return@"iPhone 7 Plus"; if([platform isEqualToString:@"iPhone10,1"]) return@"iPhone 8"; if([platform isEqualToString:@"iPhone10,4"]) return@"iPhone 8"; if([platform isEqualToString:@"iPhone10,2"]) return@"iPhone 8 Plus"; if([platform isEqualToString:@"iPhone10,5"]) return@"iPhone 8 Plus"; if([platform isEqualToString:@"iPhone10,3"]) return@"iPhone X"; if([platform isEqualToString:@"iPhone10,6"]) return@"iPhone X"; if([platform isEqualToString:@"iPod1,1"]) return@"iPod Touch 1G"; if([platform isEqualToString:@"iPod2,1"]) return@"iPod Touch 2G"; if([platform isEqualToString:@"iPod3,1"]) return@"iPod Touch 3G"; if([platform isEqualToString:@"iPod4,1"]) return@"iPod Touch 4G"; if([platform isEqualToString:@"iPod5,1"]) return@"iPod Touch 5G"; if([platform isEqualToString:@"iPad1,1"]) return@"iPad 1G"; if([platform isEqualToString:@"iPad2,1"]) return@"iPad 2"; if([platform isEqualToString:@"iPad2,2"]) return@"iPad 2"; if([platform isEqualToString:@"iPad2,3"]) return@"iPad 2"; if([platform isEqualToString:@"iPad2,4"]) return@"iPad 2"; if([platform isEqualToString:@"iPad2,5"]) return@"iPad Mini 1G"; if([platform isEqualToString:@"iPad2,6"]) return@"iPad Mini 1G"; if([platform isEqualToString:@"iPad2,7"]) return@"iPad Mini 1G"; if([platform isEqualToString:@"iPad3,1"]) return@"iPad 3"; if([platform isEqualToString:@"iPad3,2"]) return@"iPad 3"; if([platform isEqualToString:@"iPad3,3"]) return@"iPad 3"; if([platform isEqualToString:@"iPad3,4"]) return@"iPad 4"; if([platform isEqualToString:@"iPad3,5"]) return@"iPad 4"; if([platform isEqualToString:@"iPad3,6"]) return@"iPad 4"; if([platform isEqualToString:@"iPad4,1"]) return@"iPad Air"; if([platform isEqualToString:@"iPad4,2"]) return@"iPad Air"; if([platform isEqualToString:@"iPad4,3"]) return@"iPad Air"; if([platform isEqualToString:@"iPad4,4"]) return@"iPad Mini 2G"; if([platform isEqualToString:@"iPad4,5"]) return@"iPad Mini 2G"; if([platform isEqualToString:@"iPad4,6"]) return@"iPad Mini 2G"; if([platform isEqualToString:@"iPad4,7"]) return@"iPad Mini 3"; if([platform isEqualToString:@"iPad4,8"]) return@"iPad Mini 3"; if([platform isEqualToString:@"iPad4,9"]) return@"iPad Mini 3"; if([platform isEqualToString:@"iPad5,1"]) return@"iPad Mini 4"; if([platform isEqualToString:@"iPad5,2"]) return@"iPad Mini 4"; if([platform isEqualToString:@"iPad5,3"]) return@"iPad Air 2"; if([platform isEqualToString:@"iPad5,4"]) return@"iPad Air 2"; if([platform isEqualToString:@"iPad6,3"]) return@"iPad Pro 9.7"; if([platform isEqualToString:@"iPad6,4"]) return@"iPad Pro 9.7"; if([platform isEqualToString:@"iPad6,7"]) return@"iPad Pro 12.9"; if([platform isEqualToString:@"iPad6,8"]) return@"iPad Pro 12.9"; if([platform isEqualToString:@"i386"]) return@"iPhone Simulator"; if([platform isEqualToString:@"x86_64"]) return@"iPhone Simulator"; return platform;
}
六、IP地址获取，只适用于WiFi网络需要添加以下头文件和宏定义
#import <ifaddrs.h> //ip
#import <arpa/inet.h>
#import <net/if.h>
#import <__clang_cuda_runtime_wrapper.h> #define IOS_CELLULAR @"pdp_ip0"
#define IOS_WIFI @"en0"
#define IOS_VPN @"utun0"
#define IP_ADDR_IPv4 @"ipv4"
#define IP_ADDR_IPv6 @"ipv6"
方法一、
- (NSString *)deviceIPAdress {
NSString *address = @"an error occurred when obtaining ip address";
struct ifaddrs *interfaces = NULL;
struct ifaddrs *temp_addr = NULL;
int success = ;
success = getifaddrs(&interfaces);
if (success == ) // 0 表示获取成功
{
temp_addr = interfaces;
while (temp_addr != NULL) {
if( temp_addr->ifa_addr->sa_family == AF_INET) {
// Check if interface is en0 which is the wifi connection on the iPhone
if ([[NSString stringWithUTF8String:temp_addr->ifa_name] isEqualToString:@"en0"]) {
// Get NSString from C String
address = [NSString stringWithUTF8String:inet_ntoa(((struct sockaddr_in *)temp_addr->ifa_addr)->sin_addr)];
}
}
temp_addr = temp_addr->ifa_next;
}
}
freeifaddrs(interfaces);
return address;
}
方法二、获取设备当前网络IP地址 (WiFi 手机流量通用)
//获取IPV4地址
+ (NSString *)getDevicesIPV4Address
{
return [self getDevicesIPAddress:YES];
} //获取IPV6地址
+ (NSString *)getDevicesIPV6Address
{
return [self getDevicesIPAddress:NO];
}
+ (NSString *)getDevicesIPAddress:(BOOL)preferIPv4
{
NSArray *searchArray = preferIPv4 ? @[IOS_VPN @"/" IP_ADDR_IPv4, IOS_VPN @"/" IP_ADDR_IPv6, IOS_WIFI @"/" IP_ADDR_IPv4, IOS_WIFI @"/" IP_ADDR_IPv6, IOS_CELLULAR @"/" IP_ADDR_IPv4, IOS_CELLULAR @"/" IP_ADDR_IPv6 ] : @[ IOS_VPN @"/" IP_ADDR_IPv6, IOS_VPN @"/" IP_ADDR_IPv4, IOS_WIFI @"/" IP_ADDR_IPv6, IOS_WIFI @"/" IP_ADDR_IPv4, IOS_CELLULAR @"/" IP_ADDR_IPv6, IOS_CELLULAR @"/" IP_ADDR_IPv4 ] ;
NSDictionary *addresses = [self getIPAddresses];
__block NSString *address;
[searchArray enumerateObjectsUsingBlock:^(NSString *key, NSUInteger idx, BOOL *stop)
{
address = addresses[key];
//筛选出IP地址格式
if([self isValidatIP:address isIpV4:preferIPv4]) *stop = YES;
} ];
return address ? address : @"0.0.0.0";
} + (BOOL)isValidatIP:(NSString *)ipAddress isIpV4:(BOOL)ipv4 {
if (ipAddress.length == ) {
return NO;
}
NSString *urlRegEx;
if (ipv4)
{
urlRegEx = @"^([01]?\\d\\d?|2[0-4]\\d|25[0-5])\\."
"([01]?\\d\\d?|2[0-4]\\d|25[0-5])\\."
"([01]?\\d\\d?|2[0-4]\\d|25[0-5])\\."
"([01]?\\d\\d?|2[0-4]\\d|25[0-5])$";
}
else
{
urlRegEx = @"^\\s*((([0-9A-Fa-f]{1,4}:){7}([0-9A-Fa-f]{1,4}|:))|(([0-9A-Fa-f]{1,4}:){6}(:[0-9A-Fa-f]{1,4}|((25[0-5]|2[0-4]\\d|1\\d\\d|[1-9]?\\d)(\\.(25[0-5]|2[0-4]\\d|1\\d\\d|[1-9]?\\d)){3})|:))|(([0-9A-Fa-f]{1,4}:){5}(((:[0-9A-Fa-f]{1,4}){1,2})|:((25[0-5]|2[0-4]\\d|1\\d\\d|[1-9]?\\d)(\\.(25[0-5]|2[0-4]\\d|1\\d\\d|[1-9]?\\d)){3})|:))|(([0-9A-Fa-f]{1,4}:){4}(((:[0-9A-Fa-f]{1,4}){1,3})|((:[0-9A-Fa-f]{1,4})?:((25[0-5]|2[0-4]\\d|1\\d\\d|[1-9]?\\d)(\\.(25[0-5]|2[0-4]\\d|1\\d\\d|[1-9]?\\d)){3}))|:))|(([0-9A-Fa-f]{1,4}:){3}(((:[0-9A-Fa-f]{1,4}){1,4})|((:[0-9A-Fa-f]{1,4}){0,2}:((25[0-5]|2[0-4]\\d|1\\d\\d|[1-9]?\\d)(\\.(25[0-5]|2[0-4]\\d|1\\d\\d|[1-9]?\\d)){3}))|:))|(([0-9A-Fa-f]{1,4}:){2}(((:[0-9A-Fa-f]{1,4}){1,5})|((:[0-9A-Fa-f]{1,4}){0,3}:((25[0-5]|2[0-4]\\d|1\\d\\d|[1-9]?\\d)(\\.(25[0-5]|2[0-4]\\d|1\\d\\d|[1-9]?\\d)){3}))|:))|(([0-9A-Fa-f]{1,4}:){1}(((:[0-9A-Fa-f]{1,4}){1,6})|((:[0-9A-Fa-f]{1,4}){0,4}:((25[0-5]|2[0-4]\\d|1\\d\\d|[1-9]?\\d)(\\.(25[0-5]|2[0-4]\\d|1\\d\\d|[1-9]?\\d)){3}))|:))|(:(((:[0-9A-Fa-f]{1,4}){1,7})|((:[0-9A-Fa-f]{1,4}){0,5}:((25[0-5]|2[0-4]\\d|1\\d\\d|[1-9]?\\d)(\\.(25[0-5]|2[0-4]\\d|1\\d\\d|[1-9]?\\d)){3}))|:)))(%.+)?\\s*$";
} NSError *error;

return YES;
}
}
return NO;
} + (NSDictionary *)getIPAddresses
{
NSMutableDictionary *addresses = [NSMutableDictionary dictionaryWithCapacity:]; // retrieve the current interfaces - returns 0 on success
struct ifaddrs *interfaces;

}
const struct sockaddr_in *addr = (const struct sockaddr_in*)interface->ifa_addr;
char addrBuf[ MAX(INET_ADDRSTRLEN, INET6_ADDRSTRLEN) ];

七、获取手机当前连接的WiFi名称
- (NSString *)getWifiName
