iOS获取当前设备的型号、分辨率、运营商以及地理位置

最近做一个需求：后端需要统计使用我们APP产品的用户手机的各种信息，这些信息包括：设备品牌、设备型号、设备分辨率、操作系统、运营商、APP版本号、设备ID（UUID）、地址位置。这些信息其实获取也都不是很难，简单记录一下：

//首先获取当前设备对象
UIDevice *device = [UIDevice currentDevice];

/* 系统名 */
NSString *systemName = [device systemName];

/* 系统版本号 */
NSString *phoneVersion = [device systemVersion];

/* 设备品牌 */
NSString *brand = [device model];

/* 设备型号 */  iphoneType方法在后面实现
NSString *model = [self iphoneType];

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

/* 运营商 */
首先需要引入以下两个系统类：
#import <CoreTelephony/CTTelephonyNetworkInfo.h>
#import <CoreTelephony/CTCarrier.h>

CTTelephonyNetworkInfo *info = [[CTTelephonyNetworkInfo alloc] init];
CTCarrier *carrier = [info subscriberCellularProvider];
//当前手机所属运营商名称
NSString *mobileCarrier;
//先判断有没有SIM卡，如果没有则不获取本机运营商
if (!carrier.isoCountryCode) {
mobileCarrier = @"无运营商";
}else{
mobileCarrier = [carrier carrierName];
}

/* app当前版本号 */
NSDictionary *infoDict = [[NSBundle mainBundle] infoDictionary];
NSString *currentVersion = infoDict[@"CFBundleShortVersionString"];

/* 设备ID */
NSUUID *uuid = device.identifierForVendor;
NSString *devideID = uuid.UUIDString;

/* 地理位置 */
[self Collocaction];

获取设备型号的方法：

- (NSString *)iphoneType {

//需要导入头文件：#import <sys/utsname.h>

struct utsname systemInfo;

uname(&systemInfo);

NSString *platform = [NSString stringWithCString:systemInfo.machine encoding:NSASCIIStringEncoding];

if ([platform isEqualToString:@"iPhone1,1"]) return @"iPhone 2G";

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

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

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

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

if ([platform isEqualToString:@"iPhone3,3"]) return @"iPhone 4";

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

if ([platform isEqualToString:@"iPhone5,1"]) return @"iPhone 5";

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

if ([platform isEqualToString:@"iPhone5,3"]) return @"iPhone 5c";

if ([platform isEqualToString:@"iPhone5,4"]) return @"iPhone 5c";

if ([platform isEqualToString:@"iPhone6,1"]) return @"iPhone 5s";

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

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

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

if ([platform isEqualToString:@"iPhone8,1"]) return @"iPhone 6s";

if ([platform isEqualToString:@"iPhone8,2"]) return @"iPhone 6s Plus";

if ([platform isEqualToString:@"iPhone8,4"]) return @"iPhone SE";

if ([platform isEqualToString:@"iPhone9,1"]) return @"iPhone 7";

if ([platform isEqualToString:@"iPhone9,2"]) return @"iPhone 7 Plus";
return platform;
}

定位相关的实现：使用CLLocationManager和CLLocation两个类

-(void)Collocaction{

self.locationManager = [[CLLocationManager alloc] init];

[self.locationManager  requestAlwaysAuthorization];//请求授权
if ([CLLocationManager locationServicesEnabled]) {
self.locationManager.delegate = self;
self.locationManager.desiredAccuracy = kCLLocationAccuracyNearestTenMeters;
self.locationManager.distanceFilter = 200.0f;
[self.locationManager startUpdatingLocation];
}
else {
NSLog(@"请开启定位功能！");
}
}
//定位代理方法
- (void)locationManager:(CLLocationManager *)manager didUpdateToLocation:(CLLocation *)newLocation

fromLocation:(CLLocation *)oldLocation {

// 获取当前所在的城市名
CLGeocoder *geocoder = [[CLGeocoder alloc] init];
//根据经纬度反向地理编译出地址信息
[geocoder reverseGeocodeLocation:newLocation completionHandler:^(NSArray *array, NSError *error)
{
if (array.count > 0)
{
CLPlacemark *placemark = [array objectAtIndex:0];
//获取城市
NSString *city = placemark.locality;
if (!city) {
//四大直辖市的城市信息无法通过locality获得，只能通过获取省份的方法来获得（如果city为空，则可知为直辖市）
city = placemark.administrativeArea;
}
//详细地址
NSString *location = placemark.name;
//拼接成最终的位置
NSString *myLocation = [NSString stringWithFormat:@"%@%@",city,location];
}
else if (error == nil && [array count] == 0)
{
NSLog(@"No results were returned.");
}
else if (error != nil)
{
NSLog(@"An error occurred = %@", error);
}
}];

//停止定位
[manager stopUpdatingLocation];
}
// 定位失误时调用
- (void)locationManager:(CLLocationManager *)manager didFailWithError:(NSError *)error
{
NSLog(@"error:%@",error);
}
