1、获取设备号

// 获取设备型号
- (NSString *)getDeviceName
{
    // =====【需要#import "sys/utsname.h"】====
    struct utsname systemInfo;
    uname(&systemInfo);
    NSString *deviceString = [NSString stringWithCString:systemInfo.machine encoding:NSUTF8StringEncoding];
    
    if ([deviceString isEqualToString:@"iPhone3,1"])    return @"iPhone 4";
    if ([deviceString isEqualToString:@"iPhone3,2"])    return @"iPhone 4";
    if ([deviceString isEqualToString:@"iPhone3,3"])    return @"iPhone 4";
    if ([deviceString isEqualToString:@"iPhone4,1"])    return @"iPhone 4S";
    if ([deviceString isEqualToString:@"iPhone5,1"])    return @"iPhone 5";
    if ([deviceString isEqualToString:@"iPhone5,2"])    return @"iPhone 5 (GSM+CDMA)";
    if ([deviceString isEqualToString:@"iPhone5,3"])    return @"iPhone 5c (GSM)";
    if ([deviceString isEqualToString:@"iPhone5,4"])    return @"iPhone 5c (GSM+CDMA)";
    if ([deviceString isEqualToString:@"iPhone6,1"])    return @"iPhone 5s (GSM)";
    if ([deviceString isEqualToString:@"iPhone6,2"])    return @"iPhone 5s (GSM+CDMA)";
    if ([deviceString isEqualToString:@"iPhone7,1"])    return @"iPhone 6 Plus";
    if ([deviceString isEqualToString:@"iPhone7,2"])    return @"iPhone 6";
    if ([deviceString isEqualToString:@"iPhone8,1"])    return @"iPhone 6s";
    if ([deviceString isEqualToString:@"iPhone8,2"])    return @"iPhone 6s Plus";
    if ([deviceString isEqualToString:@"iPhone8,4"])    return @"iPhone SE";
    if ([deviceString isEqualToString:@"iPhone9,1"])    return @"iPhone 7";
    if ([deviceString isEqualToString:@"iPhone9,2"])    return @"iPhone 7 Plus";
    
    
    
    
    
    if ([deviceString isEqualToString:@"iPod1,1"])      return @"iPod Touch 1G";
    if ([deviceString isEqualToString:@"iPod2,1"])      return @"iPod Touch 2G";
    if ([deviceString isEqualToString:@"iPod3,1"])      return @"iPod Touch 3G";
    if ([deviceString isEqualToString:@"iPod4,1"])      return @"iPod Touch 4G";
    if ([deviceString isEqualToString:@"iPod5,1"])      return @"iPod Touch (5 Gen)";
    
    if ([deviceString isEqualToString:@"iPad1,1"])      return @"iPad";
    if ([deviceString isEqualToString:@"iPad1,2"])      return @"iPad 3G";
    if ([deviceString isEqualToString:@"iPad2,1"])      return @"iPad 2 (WiFi)";
    if ([deviceString isEqualToString:@"iPad2,2"])      return @"iPad 2";
    if ([deviceString isEqualToString:@"iPad2,3"])      return @"iPad 2 (CDMA)";
    if ([deviceString isEqualToString:@"iPad2,4"])      return @"iPad 2";
    if ([deviceString isEqualToString:@"iPad2,5"])      return @"iPad Mini (WiFi)";
    if ([deviceString isEqualToString:@"iPad2,6"])      return @"iPad Mini";
    if ([deviceString isEqualToString:@"iPad2,7"])      return @"iPad Mini (GSM+CDMA)";
    if ([deviceString isEqualToString:@"iPad3,1"])      return @"iPad 3 (WiFi)";
    if ([deviceString isEqualToString:@"iPad3,2"])      return @"iPad 3 (GSM+CDMA)";
    if ([deviceString isEqualToString:@"iPad3,3"])      return @"iPad 3";
    if ([deviceString isEqualToString:@"iPad3,4"])      return @"iPad 4 (WiFi)";
    if ([deviceString isEqualToString:@"iPad3,5"])      return @"iPad 4";
    if ([deviceString isEqualToString:@"iPad3,6"])      return @"iPad 4 (GSM+CDMA)";
    if ([deviceString isEqualToString:@"iPad4,1"])      return @"iPad Air (WiFi)";
    if ([deviceString isEqualToString:@"iPad4,2"])      return @"iPad Air (Cellular)";
    if ([deviceString isEqualToString:@"iPad4,4"])      return @"iPad Mini 2 (WiFi)";
    if ([deviceString isEqualToString:@"iPad4,5"])      return @"iPad Mini 2 (Cellular)";
    if ([deviceString isEqualToString:@"iPad4,6"])      return @"iPad Mini 2";
    if ([deviceString isEqualToString:@"iPad4,7"])      return @"iPad Mini 3";
    if ([deviceString isEqualToString:@"iPad4,8"])      return @"iPad Mini 3";
    if ([deviceString isEqualToString:@"iPad4,9"])      return @"iPad Mini 3";
    if ([deviceString isEqualToString:@"iPad5,1"])      return @"iPad Mini 4 (WiFi)";
    if ([deviceString isEqualToString:@"iPad5,2"])      return @"iPad Mini 4 (LTE)";
    if ([deviceString isEqualToString:@"iPad5,3"])      return @"iPad Air 2";
    if ([deviceString isEqualToString:@"iPad5,4"])      return @"iPad Air 2";
    if ([deviceString isEqualToString:@"iPad6,3"])      return @"iPad Pro 9.7";
    if ([deviceString isEqualToString:@"iPad6,4"])      return @"iPad Pro 9.7";
    if ([deviceString isEqualToString:@"iPad6,7"])      return @"iPad Pro 12.9";
    if ([deviceString isEqualToString:@"iPad6,8"])      return @"iPad Pro 12.9";
    
    if ([deviceString isEqualToString:@"i386"])         return @"Simulator";
    if ([deviceString isEqualToString:@"x86_64"])       return @"Simulator";
    
    
    return deviceString;
}

2、UDID UUID IDFA

UDID的全名为 Unique Device Identifier :设备唯一标识符。从名称上也可以看出,UDID这个东西是和设备有关的,而且是只和设备有关的,有点类似于MAC地址。需要把UDID这个东西添加到Provisoning Profile授权文件中,也就是把设备唯一标识符添加进去,以此来识别某一台设备。

但是如果我们代码中要用到UDID,那么应该怎么办呢?很遗憾,自从iOS5之后,苹果就禁止了通过代码访问UDID,在这之前,可以使用[[UIDevice cuurrent] uniqueIdenfier] 这个方法来获取某设备UDID,现在是不可能了

但是我们可以另一种方式获取类似于UDID的唯一标示

NSUUID *uuid = [UIDevice currentDevice].identifierForVendor;
NSLog(@"uuid 1 = %@",uuid.UUIDString);
UUID英文名称是:Universally Unique Identifier,翻译过来就是通用唯一标识符。是一个32位的十六进制序列,使用小横线来连接:8-4-4-4-12 。UUID在某一时空下是唯一的。比如在当前这一秒,全世界产生的UUID都是不一样的;当然同一台设备产生的UUID也是不一样的。
for (int i = 0; i < 10; i++)
    {
        NSString *uuid = [NSUUID UUID].UUIDString;
        NSLog(@"uuid 2 = %@",uuid);
    }

通过运行程序可以发现,循环10次,每一次打印的值都是不一样的,当然循环的再多,这个值永远不会出现两个一样的值。所以从某种程序上来说,UUID跟你的设备没有什么关系了。

IDFA(identifierForIdentifier)广告标示符,适用于对外:例如广告推广,换量等跨应用的用户追踪等。
#import <AdSupport/AdSupport.h>
NSString *adId = [[[ASIdentifierManager sharedManager] advertisingIdentifier] UUIDString];

3、获取版本号

// app版本  
NSString *appVerion = [[[NSBundle mainBundle] infoDictionary] objectForKey:@"CFBundleShortVersionString"];
 NSString *app_Version = [infoDictionary objectForKey:@"CFBundleShortVersionString"];  
NSLog(@"app版本号-->%@", appVerion);
// app名称  
 NSString *app_Name = [infoDictionary objectForKey:@"CFBundleDisplayName"];  
 // app build版本  
 NSString *app_build = [infoDictionary objectForKey:@"CFBundleVersion"]; 

4、获取电池电量

CGFloat batteryLevel = [[UIDevice currentDevice] batteryLevel];
NSLog(@"电池电量-->%f", batteryLevel);

5、获取系统号

NSString *systemName = [UIDevice currentDevice].systemName;
    NSLog(@"当前系统名称-->%@", systemName);
NSString *systemVersion = [UIDevice currentDevice].systemVersion;
NSLog(@"当前系统版本号-->%@", systemVersion);

6、获取设备IP

需要的头文件

#import "sys/utsname.h"
#include <sys/socket.h> // Per msqr
#include <sys/sysctl.h>
#include <net/if.h>
#include <net/if_dl.h>
#import <sys/sockio.h>
#import <sys/ioctl.h>
#import <arpa/inet.h>
获取IP方法
// 获取ip
- (NSString *)getDeviceIPAddresses {
    
    int sockfd = socket(AF_INET, SOCK_DGRAM, 0);
    
    
    NSMutableArray *ips = [NSMutableArray array];
    
    int BUFFERSIZE = 4096;
    
    struct ifconf ifc;
    
    char buffer[BUFFERSIZE], *ptr, lastname[IFNAMSIZ], *cptr;
    
    struct ifreq *ifr, ifrcopy;
    
    ifc.ifc_len = BUFFERSIZE;
    ifc.ifc_buf = buffer;
    
    if (ioctl(sockfd, SIOCGIFCONF, &ifc) >= 0){
        
        for (ptr = buffer; ptr < buffer + ifc.ifc_len; ){
            
            ifr = (struct ifreq *)ptr;
            int len = sizeof(struct sockaddr);
            
            if (ifr->ifr_addr.sa_len > len) {
                len = ifr->ifr_addr.sa_len;
            }
            
            ptr += sizeof(ifr->ifr_name) + len;
            if (ifr->ifr_addr.sa_family != AF_INET) continue;
            if ((cptr = (char *)strchr(ifr->ifr_name, ':')) != NULL) *cptr = 0;
            if (strncmp(lastname, ifr->ifr_name, IFNAMSIZ) == 0) continue;
            
            memcpy(lastname, ifr->ifr_name, IFNAMSIZ);
            ifrcopy = *ifr;
            ioctl(sockfd, SIOCGIFFLAGS, &ifrcopy);
            
            if ((ifrcopy.ifr_flags & IFF_UP) == 0) continue;
            
            NSString *ip = [NSString  stringWithFormat:@"%s", inet_ntoa(((struct sockaddr_in *)&ifr->ifr_addr)->sin_addr)];
            [ips addObject:ip];
        }
    }
    
    close(sockfd);
    NSString *deviceIP = @"";
    
    for (int i=0; i < ips.count; i++) {
        if (ips.count > 0) {
            deviceIP = [NSString stringWithFormat:@"%@",ips.lastObject];
        }
    }
    return deviceIP;
}

7、禁止锁屏

默认情况下,当设备一段时间没有触控动作时,iOS会锁住屏幕。但有一些应用是不需要锁屏的,比如视频播放器。

[UIApplication sharedApplication].idleTimerDisabled = YES;
或
[[UIApplication sharedApplication] setIdleTimerDisabled:YES];

8、获取手机安装的应用

Class c =NSClassFromString(@"LSApplicationWorkspace");
id s = [(id)c performSelector:NSSelectorFromString(@"defaultWorkspace")];
NSArray *array = [s performSelector:NSSelectorFromString(@"allInstalledApplications")];
for (id item in array)
{
    NSLog(@"%@",[item performSelector:NSSelectorFromString(@"applicationIdentifier")]);
    //NSLog(@"%@",[item performSelector:NSSelectorFromString(@"bundleIdentifier")]);
    NSLog(@"%@",[item performSelector:NSSelectorFromString(@"bundleVersion")]);
    NSLog(@"%@",[item performSelector:NSSelectorFromString(@"shortVersionString")]);
}
