iOS 基本设备信息查询

开发中总会遇到很多需要查询设备及App信息的情况,有时候也是为了更好的用户体验或者为了bug跟踪，可能会需要获取用户的应用信息、系统信息、设备信息。这些信息的获取可以根据不同的设备或者App、系统版本来提供不同的功能或更好的用户体验，或者让开发者能更好的分析用户的问题原因。

(一)设备及App信息查询

1.获取设备名称

OC代码

NSString *deviceName = [[UIDevice currentDevice] name];

Swift代码

let deviceName = UIDevice.currentDevice().name

2.获取系统版本号

OC代码

NSString *sysVersion = [[UIDevice currentDevice] systemVersion];

Swift代码

let sysVersion = UIDevice.currentDevice().systemVersion

3.获取设备唯一标识符

OC代码

NSString *deviceUUID = [[[UIDevice currentDevice] identifierForVendor] ;

Swift代码

let deviceUUID = UIDevice.currentDevice().identifierForVendor?.UUIDString

4.获取设备型号

OC代码

NSString *deviceModel = [[UIDevice currentDevice] model];

Swift代码

let deviceModel = UIDevice.currentDevice().model

5.获取App相关的信息

OC代码

NSDictionary *infoDic = [[NSBundle mainBundle] infoDictionary];

// 获取App的版本号

NSString *appVersion = [infoDic objectForKey:@”CFBundleShortVersionString”];

// 获取App的build版本

NSString *appBuildVersion = [infoDic objectForKey:@”CFBundleVersion”];

// 获取App的名称

NSString *appName = [infoDic objectForKey:@”CFBundleDisplayName”];

Swift代码

let infoDic = NSBundle.mainBundle().infoDictionary

// 获取App的版本号

let appVersion = infoDic?[“CFBundleShortVersionString”]

// 获取App的build版本

let appBuildVersion = infoDic?[“CFBundleVersion”]

// 获取App的名称

let appName = infoDic?[“CFBundleDisplayName”]

(二)iOS获取具体设备型号

OC代码获取iOS设备型号：

// 需要#import + (NSString*)deviceModelName

{

struct utsname systemInfo;

uname(&systemInfo);

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

//iPhone 系列

if ([deviceModel isEqualToString:@”iPhone1,1”]) return @”iPhone 1G”;

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

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

if ([deviceModel isEqualToString:@”iPhone3,1”]) return @”iPhone 4”;

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

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

if ([deviceModel isEqualToString:@”iPhone5,1”]) return @”iPhone 5”;

if ([deviceModel isEqualToString:@”iPhone5,2”]) return @”iPhone 5”;

if ([deviceModel isEqualToString:@”iPhone5,3”]) return @”iPhone 5C”;

if ([deviceModel isEqualToString:@”iPhone5,4”]) return @”iPhone 5C”;

if ([deviceModel isEqualToString:@”iPhone6,1”]) return @”iPhone 5S”;

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

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

if ([deviceModel isEqualToString:@”iPhone7,2”]) return @”iPhone 6”;

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

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

if ([deviceModel isEqualToString:@”iPhone9,1”]) return @”iPhone 7 (CDMA)”;

if ([deviceModel isEqualToString:@”iPhone9,3”]) return @”iPhone 7 (GSM)”;

if ([deviceModel isEqualToString:@”iPhone9,2”]) return @”iPhone 7 Plus (CDMA)”;

if ([deviceModel isEqualToString:@”iPhone9,4”]) return @”iPhone 7 Plus (GSM)”;

//iPod 系列

if ([deviceModel isEqualToString:@”iPod1,1”]) return @”iPod Touch 1G”;

if ([deviceModel isEqualToString:@”iPod2,1”]) return @”iPod Touch 2G”;

if ([deviceModel isEqualToString:@”iPod3,1”]) return @”iPod Touch 3G”;

if ([deviceModel isEqualToString:@”i
4000
Pod4,1”]) return @”iPod Touch 4G”;

if ([deviceModel isEqualToString:@”iPod5,1”]) return @”iPod Touch 5G”;

//iPad 系列

if ([deviceModel isEqualToString:@”iPad1,1”]) return @”iPad”;

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

if ([deviceModel isEqualToString:@”iPad2,2”]) return @”iPad 2 (GSM)”;

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

if ([deviceModel isEqualToString:@”iPad2,4”]) return @”iPad 2 (32nm)”;

if ([deviceModel isEqualToString:@”iPad2,5”]) return @”iPad mini (WiFi)”;

if ([deviceModel isEqualToString:@”iPad2,6”]) return @”iPad mini (GSM)”;

if ([deviceModel isEqualToString:@”iPad2,7”]) return @”iPad mini (CDMA)”;

if ([deviceModel isEqualToString:@”iPad3,1”]) return @”iPad 3(WiFi)”;

if ([deviceModel isEqualToString:@”iPad3,2”]) return @”iPad 3(CDMA)”;

if ([deviceModel isEqualToString:@”iPad3,3”]) return @”iPad 3(4G)”;

if ([deviceModel isEqualToString:@”iPad3,4”]) return @”iPad 4 (WiFi)”;

if ([deviceModel isEqualToString:@”iPad3,5”]) return @”iPad 4 (4G)”;

if ([deviceModel isEqualToString:@”iPad3,6”]) return @”iPad 4 (CDMA)”;

if ([deviceModel isEqualToString:@”iPad4,1”]) return @”iPad Air”;

if ([deviceModel isEqualToString:@”iPad4,2”]) return @”iPad Air”;

if ([deviceModel isEqualToString:@”iPad4,3”]) return @”iPad Air”;

if ([deviceModel isEqualToString:@”iPad5,3”]) return @”iPad Air 2”;

if ([deviceModel isEqualToString:@”iPad4,4”]

||[deviceModel isEqualToString:@”iPad4,5”]

||[deviceModel isEqualToString:@”iPad4,6”]) return @”iPad mini 2”;

if ([deviceModel isEqualToString:@”iPad4,7”]

||[deviceModel isEqualToString:@”iPad4,8”]

||[deviceModel isEqualToString:@”iPad4,9”]) return @”iPad mini 3”;

return deviceModel;

}

记得一定要#import啊

Swift代码获取iOS设备型号：

//MARK: - UIDevice延展

public extension UIDevice {

var modelName: String {

var systemInfo = utsname()

uname(&systemInfo)

let machineMirror = Mirror(reflecting: systemInfo.machine)

let identifier = machineMirror.children.reduce(“”) { identifier, element in

guard let value = element.value as? Int8 where value != 0 else { return identifier }

return identifier + String(UnicodeScalar(UInt8(value)))

}

switch identifier {

case “iPod5,1”: return “iPod Touch 5”

case “iPod7,1”: return “iPod Touch 6”

case “iPhone3,1”, “iPhone3,2”, “iPhone3,3”: return “iPhone 4”

case “iPhone4,1”: return “iPhone 4s”

case “iPhone5,1”, “iPhone5,2”: return “iPhone 5”

case “iPhone5,3”, “iPhone5,4”: return “iPhone 5c”

case “iPhone6,1”, “iPhone6,2”: return “iPhone 5s”

case “iPhone7,2”: return “iPhone 6”

case “iPhone7,1”: return “iPhone 6 Plus”

case “iPhone8,1”: return “iPhone 6s”

case “iPhone8,2”: return “iPhone 6s Plus”

case “iPhone9,1”: return “iPhone 7 (CDMA)”

case “iPhone9,3”: return “iPhone 7 (GSM)”

case “iPhone9,2”: return “iPhone 7 Plus (CDMA)”

case “iPhone9,4”: return “iPhone 7 Plus (GSM)”

case “iPad2,1”, “iPad2,2”, “iPad2,3”, “iPad2,4”:return “iPad 2”

case “iPad3,1”, “iPad3,2”, “iPad3,3”: return “iPad 3”

case “iPad3,4”, “iPad3,5”, “iPad3,6”: return “iPad 4”

case “iPad4,1”, “iPad4,2”, “iPad4,3”: return “iPad Air”

case “iPad5,3”, “iPad5,4”: return “iPad Air 2”

case “iPad2,5”, “iPad2,6”, “iPad2,7”: return “iPad Mini”

case “iPad4,4”, “iPad4,5”, “iPad4,6”: return “iPad Mini 2”

case “iPad4,7”, “iPad4,8”, “iPad4,9”: return “iPad Mini 3”

case “iPad5,1”, “iPad5,2”: return “iPad Mini 4”

case “iPad6,7”, “iPad6,8”: return “iPad Pro”

case “AppleTV5,3”: return “Apple TV”

case “i386”, “x86_64”: return “Simulator”

default: return identifier

}

}

}

(三)其他设备信息查询(不经常用)

- (void)deviceInfo {

UIDevice *dev = [UIDevice currentDevice];

NSLog(@"是否支持多任务：%@", dev.multitaskingSupported?@"是":@"否");
NSLog(@"设备名字：%@", dev.name);
NSLog(@"系统名字：%@", dev.systemName);
NSLog(@"设备model：%@", dev.model);
NSLog(@"设备本地化model：%@", dev.localizedModel);
NSLog(@"用户界面类型：%ld", (long)dev.userInterfaceIdiom);
NSLog(@"设备厂商标识：%@", dev.identifierForVendor);
NSLog(@"设备方向：%ld", (long)dev.orientation);
NSLog(@"是否可以生成设备方向通知：%@", dev.generatesDeviceOrientationNotifications?@"是":@"否");
NSLog(@"设备电量：%f", dev.batteryLevel);
NSLog(@"电量监测是否启用：%@", dev.batteryMonitoringEnabled?@"是":@"否");
NSLog(@"设备电量状态：%ld", (long)dev.batteryState);
NSLog(@"距离感应器是否可以使用：%@", dev.proximityMonitoringEnabled?@"是":@"否");
NSLog(@"距离感应器是否打开：%@", dev.proximityState?@"是":@"否");
