iOS 如何获取手机型号、系统版本、电池电量

1、手机型号：iPhone 6

NSString* phoneModel = [self iphoneType]; //方法在下面

2、手机系统版本：9.1

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

3、手机系统：iPhone OS

NSString * iponeM = [[UIDevice currentDevice] systemName];

4、电池电量

CGFloat batteryLevel = [[UIDevice currentDevice] batteryLevel];

获取手机型号需导入头文件：

#import <sys/utsname.h>

//获取手机型号
- (NSString *)iphoneType
{
struct utsname systemInfo;

uname(&systemInfo);

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