获取设备信息总结
1、获取设备的信息
UIDevice *device = [[UIDevice alloc] int];
NSString *name = device.name; //获取设备所有者的名称
NSString *model = device.name; //获取设备的类别
NSString *type = device.localizedModel; //获取本地化版本
NSString *systemName = device.systemName; //获取当前运行的系统
NSString *systemVersion = device.systemVersion;//获取当前系统的版本
2、获取设备的唯一标示符
NSString *identifier = [[[UIDevice currentDevice] identifierForVendor] UUIDString];
3、为系统创建一个随机的标示符
(NSString*) createUUID
{
NSString *id = [[NSUserDefaults standardUserDefaults] objectForKey:@"UUID"]; //获取标识为"UUID"的值
if(id == nil)
{
if([[[UIDevice currentDevice] systemVersion] floatValue] > 6.0)
{
NSString *identifierNumber = [[NSUUID UUID] UUIDString]; //ios 6.0 之后可以使用的api
[[NSUserDefaults standardUserDefaults] setObject:identifierNumber forKey:@"UUID"]; //保存为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、获取当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、获取运营商的信息
需要先导入头文件
#import <CoreTelephony/CTCarrier.h>
#import <CoreTelephony/CTTelephonyNetworkInfo.h>
创建对象
CCTelephonyNetworkInfo *info = [[CTTelephonyNetworkInfo alloc] init];
获取运行商的名称
CTCarrier *carrier = [info subscriberCellularProvider];
NSString *mCarrier = [NSString stringWithFormat:@"%@",[carrier carrierName]];
获取当前网络的类型
ios7之后可以按照以下方式获取。方便而且类型多
NSString *mConnectType = [[NSString alloc] initWithFormat:@"%@",info.currentRadioAccessTechnology];
类型有以下：
CTRadioAccessTechnologyGPRS //介于2G和3G之间，也叫2.5G ,过度技术
CTRadioAccessTechnologyEdge //EDGE为GPRS到第三代移动通信的过渡，EDGE俗称2.75G
CTRadioAccessTechnologyWCDMA
CTRadioAccessTechnologyHSDPA //亦称为3.5G(3?G)
CTRadioAccessTechnologyHSUPA //3G到4G的过度技术
CTRadioAccessTechnologyCDMA1x //3G
CTRadioAccessTechnologyCDMAEVDORev0 //3G标准
CTRadioAccessTechnologyCDMAEVDORevA
CTRadioAccessTechnologyCDMAEVDORevB
CTRadioAccessTechnologyeHRPD //电信使用的一种3G到4G的演进技术， 3.75G
CTRadioAccessTechnologyLTE //接近4G
