2.获取手机类型:NSString* phoneModel = [self iphoneType];//方法在下面

3.获取手机系统:NSString * iponeM = [[UIDevice currentDevice] systemName];

4.获取电池电量:CGFloat batteryLevel=[[UIDevicecurrentDevice]batteryLevel];

5.获取手机版本号

导入头文件：import<sys/utsname.h>

struct utsname systemInfo;

uname(&systemInfo);

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