iOS获取设备型号和App版本号等信息

iOS开发过程中，有时候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。

1.获取设备名称：

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

2.获取系统版本号：

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

3.获取设备唯一标识符

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

4.获取设备的型号

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

5.获取app相关信息：

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"];

OC代码获取iOS设备型号：

// 需要#import <sys/utsname.h>
+ (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"<

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:@"iPod4,1"])      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:@"iPad5,4"])      return @"iPad Air 2";
if ([deviceModel isEqualToString:@"i386"])         return @"Simulator";
if ([deviceModel isEqualToString:@"x86_64"])       return @"Simulator";

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 <sys/utsname.h>

之后

let modelName = UIDevice.currentDevice().modelName
