[IOS]如何判断机型

1.引入头文件：

#import <sys/utsname.h>

2.

-(NSString *)getIphoneType{
    struct utsname systemInfo;
    uname(&systemInfo);
    NSString *platform = [NSString stringWithCString:systemInfo.machine encoding:NSASCIIStringEncoding];
    if ([platform isEqualToString:@"iPhone4,1"]) return @"iPhone 4S";
    return platform;
}
