一、判断设备

 
        //设备名称
       
        return
        [UIDevice currentDevice].name;
       
        //设备型号，只可得到是何设备，无法得到是第几代设备
       
        return
        [UIDevice currentDevice].model;
       
        //系统版本型号,如iPhone OS 
       
        return
        [UIDevice currentDevice].systemVersion;
       
        //系统版本名称，如6.1.3
       
        return
        [UIDevice currentDevice].systemName;

 
        //判断是否为iPhone
       
        #define IS_IPHONE (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPhone)
       
        //判断是否为iPad
       
        #define IS_IPAD (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad)
       
        //判断是否为ipod
       
        #define IS_IPOD ([[[UIDevice currentDevice] model] isEqualToString:@"iPod touch"])
       
        //判断是否为iPhone5
       
        #define IS_IPHONE_5_SCREEN [[UIScreen mainScreen] bounds].size.height >= 568.0f && [[UIScreen mainScreen] bounds].size.height < 1024.0f

- (NSString*)deviceString

{

// 需要#import "sys/utsname.h"

struct utsname systemInfo;

uname(&systemInfo);

NSString *deviceString = [NSString stringWithCString:systemInfo.machine encoding:NSUTF8StringEncoding];

if ([deviceString isEqualToString:@"iPhone1,1"]) return @"iPhone 1G";

if ([deviceString isEqualToString:@"iPhone1,2"]) return @"iPhone 3G";

if ([deviceString isEqualToString:@"iPhone2,1"]) return @"iPhone 3GS";

if ([deviceString isEqualToString:@"iPhone3,1"]) return @"iPhone 4";

if ([deviceString isEqualToString:@"iPhone4,1"]) return @"iPhone 4S";

if ([deviceString isEqualToString:@"iPhone5,2"]) return @"iPhone 5";

if ([deviceString isEqualToString:@"iPhone6,2"]) return @"iPhone 5S";

if ([deviceString isEqualToString:@"iPhone7,1"]) return @"iPhone 6Plus";

if ([deviceString isEqualToString:@"iPhone7,2"]) return @"iPhone 6";

if ([deviceString isEqualToString:@"iPhone3,2"]) return @"Verizon iPhone 4";

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:@"iPad1,1"]) return @"iPad";

if ([deviceString isEqualToString:@"iPad2,1"]) return @"iPad 2 (WiFi)";

if ([deviceString isEqualToString:@"iPad2,2"]) return @"iPad 2 (GSM)";

if ([deviceString isEqualToString:@"iPad2,3"]) return @"iPad 2 (CDMA)";

if ([deviceString isEqualToString:@"i386"]) return @"Simulator";

if ([deviceString isEqualToString:@"x86_64"]) return @"Simulator";

NSLog(@"NOTE: Unknown device type: %@", deviceString);

return deviceString;

}

二、判断网络连接状态

1、导入SystemConfiguration.framework,并#import<SystemConfiguration/SCNetworkReachability.h>

2、判断设备是否联网

 
        + (
        BOOL
        )connectedToNetwork{
       
        //创建零地址，0.0.0.0的地址表示查询本机的网络连接状态
       
        struct
        sockaddr_storage zeroAddress;
       
        bzero(&zeroAddress,
        sizeof
        (zeroAddress));
       
        zeroAddress.ss_len = 
        sizeof
        (zeroAddress);
       
        zeroAddress.ss_family = AF_INET;
       
        // Recover reachability flags
       
        SCNetworkReachabilityRef defaultRouteReachability = SCNetworkReachabilityCreateWithAddress(NULL, (
        struct
        sockaddr *)&zeroAddress);
       
        SCNetworkReachabilityFlags flags;
       
        //获得连接的标志
       
        BOOL
        didRetrieveFlags = SCNetworkReachabilityGetFlags(defaultRouteReachability, &flags);
       
        CFRelease(defaultRouteReachability);
       
        //如果不能获取连接标志，则不能连接网络，直接返回
       
        if
        (!didRetrieveFlags)
       
        {
       
        return
        NO;
       
        }
       
        //根据获得的连接标志进行判断
       
        BOOL
        isReachable = flags & kSCNetworkFlagsReachable;
       
        BOOL
        needsConnection = flags & kSCNetworkFlagsConnectionRequired;
       
        return
        (isReachable&&!needsConnection) ? YES : NO;
       
        }
