1.判斷系統(tǒng)版本

NSString *phoneVerion = [[UIDevice currentDevice] systemVersion];
DLog(@"系統(tǒng)版本--%@",phoneVerion);

2.判斷手機型號

-(NSString*)iphoneType
{
    //導(dǎo)入#import "sys/utsname.h"
    struct utsname systemInfo;
    uname(&systemInfo);
    NSString *deviceModel = [NSString stringWithCString:systemInfo.machine encoding:NSUTF8StringEncoding];
