    • 1.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];
}
    • 2.获取电池状态(UIDeviceBatteryState为枚举类型)
    -(UIDeviceBatteryState)getBatteryStauts
{
    return [UIDevice currentDevice].batteryState;
}
    • 3.获取总内存大小
    -(long long)getTotalMemorySize
{
    return [NSProcessInfo processInfo].physicalMemory;
}
    • 4.获取当前可用内存
    -(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));
}
    • 5.获取已使用内存
    - (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;
}
    • 6.获取总磁盘容量
    include <sys/mount.h>
-(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;
}
    • 7.获取可用磁盘容量
    -(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;
}
    • 8.容量转换
    -(NSString *)fileSizeToString:(unsigned long long)fileSize
{
    NSInteger KB = 1024;
    NSInteger MB = KB*KB;
    NSInteger GB = MB*KB;

    if (fileSize < 10)  {
        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];
    }
}
    • 9.型号
    #import <sys/sysctl.h>

+ (NSString *)getCurrentDeviceModel:(UIViewController *)controller
{
    int mib[2];
    size_t len;
    char *machine;
    
    mib[0] = CTL_HW;
    mib[1] = HW_MACHINE;
    sysctl(mib, 2, NULL, &len, NULL, 0);
    machine = malloc(len);
    sysctl(mib, 2, machine, &len, NULL, 0);
    
    NSString *platform = [NSString stringWithCString:machine encoding:NSASCIIStringEncoding];
    free(machine);

    if ([platform isEqualToString:@"x86_64"])    return @"iPhone Simulator";
    return platform;
}

    可以根据自己的需求增改。有人说也可以按照手机屏幕来判断，但5和5s/5c等手机屏幕相同尺寸则无法判断。。。我只做了iPhone的机型，所以iPad和iPod Touch的信息并没有更新到最新，也请朋友们补充。

    • 10.IP地址
    #import <ifaddrs.h>和#import <arpa/inet.h>

- (NSString *)deviceIPAdress {
    NSString *address = @"an error occurred when obtaining ip address";
    struct ifaddrs *interfaces = NULL;
    struct ifaddrs *temp_addr = NULL;
    int success = 0;
    
    success = getifaddrs(&interfaces);
    
    if (success == 0) { // 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;
}
    • 11.当前手机连接的WIFI名称(SSID)
    需要#import <SystemConfiguration/CaptiveNetwork.h>

- (NSString *)getWifiName
{
    NSString *wifiName = nil;
    
    CFArrayRef wifiInterfaces = CNCopySupportedInterfaces();
    if (!wifiInterfaces) {
        return nil;
    }
    
    NSArray *interfaces = (__bridge NSArray *)wifiInterfaces;
    
    for (NSString *interfaceName in interfaces) {
        CFDictionaryRef dictRef = CNCopyCurrentNetworkInfo((__bridge CFStringRef)(interfaceName));
        
        if (dictRef) {
            NSDictionary *networkInfo = (__bridge NSDictionary *)dictRef;

            wifiName = [networkInfo objectForKey:(__bridge NSString *)kCNNetworkInfoKeySSID];
            
            CFRelease(dictRef);
        }
    }
    
    CFRelease(wifiInterfaces);
    return wifiName;
}
    • 12.当前手机系統版本
    [[[UIDevice currentDevice] systemVersion] floatValue] ;
