ios獲取設備信息

1、獲取設備的信息

UIDevice *device = [[UIDevice alloc] int];
NSString *name = device.name;       //獲取設備所有者的名稱
NSString *model = device.name;      //獲取設備的類別
NSString *type = device.localizedModel; //獲取本地化版本
NSString *systemName = device.systemName;   //獲取當前運行的系統
NSString *systemVersion = device.systemVersion;//獲取當前系統的版本

2、獲取設備的唯一標示符

NSString *identifier = [[[UIDevice currentDevice] identifierForVendor] UUIDString];

3、爲系統創建一個隨機的標示符

(NSString*) createUUID
{
    NSString *id = [[NSUserDefaults standardUserDefaults] objectForKey:@"UUID"];    //獲取標識爲"UUID"的值
    if(id == nil)
    {
        if([[[UIDevice currentDevice] systemVersion] floatValue] > 6.0)
        {
            NSString *identifierNumber = [[NSUUID UUID] UUIDString];                //ios 6.0 之後可以使用的api
            [[NSUserDefaults standardUserDefaults] setObject:identifierNumber forKey:@"UUID"];  //保存爲UUID
            [[NSUserDefaults standardUserDefaults] synchronize];
        }
        else{
            CFUUIDRef uuid = CFUUIDCreate(NULL);
            CFStringRef uuidString = CFUUIDCreateString(NULL, uuid);                    //ios6.0之前使用的api
            NSString *identifierNumber = [NSString stringWithFormat:@"%@", uuidString];
            [[NSUserDefaults standardUserDefaults] setObject:identifierNumber forKey:@"UUID"];
            [[NSUserDefaults standardUserDefaults] synchronize];
            CFRelease(uuidString);
            CFRelease(uuid);
        }
        return [[NSUserDefaults standardUserDefaults] objectForKey@"UUID"];
    }
    return id;
}

4、獲取當前屏幕分辨率的信息

CGRect rect = [[UIScreen mainScreen] bounds];
CGFloat scale = [[UIScreen mainScreen].scale];
CGFloat width = rect.size.width * scale;
CGFloat height = rect.size.height * scale;

5、獲取運營商的信息
需要先導入頭文件

#import <CoreTelephony/CTCarrier.h>
#import <CoreTelephony/CTTelephonyNetworkInfo.h>

創建對象

CCTelephonyNetworkInfo *info = [[CTTelephonyNetworkInfo alloc] init];

獲取運行商的名稱

CTCarrier *carrier = [info subscriberCellularProvider];
NSString *mCarrier = [NSString stringWithFormat:@"%@",[carrier carrierName]];

獲取當前網絡的類型
ios7之後可以按照以下方式獲取。方便而且類型多

NSString *mConnectType = [[NSString alloc] initWithFormat:@"%@",info.currentRadioAccessTechnology];

類型有以下：

CTRadioAccessTechnologyGPRS         //介於2G和3G之間，也叫2.5G ,過度技術
CTRadioAccessTechnologyEdge         //EDGE爲GPRS到第三代移動通信的過渡，EDGE俗稱2.75G
CTRadioAccessTechnologyWCDMA
CTRadioAccessTechnologyHSDPA            //亦稱爲3.5G(3?G)
CTRadioAccessTechnologyHSUPA            //3G到4G的過度技術
CTRadioAccessTechnologyCDMA1x       //3G
CTRadioAccessTechnologyCDMAEVDORev0    //3G標準<span
