我知道这可能太晚了，无论如何可能都不回答这个问题，但我想'是什么heck' - 确定设备范围是一个很好的代码，在cas中您可能需要不同的功能。

I know it's probably way too late, and probably doesn't answer the question anyway, but I figured 'what the heck' – it's a nice bit of code to determine ranges of devices, where in cases you may want different functionality.

#import <sys/sysctl.h>

-(BOOL)isANewerDevice{

    size_t size;
    sysctlbyname("hw.machine", NULL, &size, NULL, 0);
    char *machine = malloc(size);
    sysctlbyname("hw.machine", machine, &size, NULL, 0);
    NSString *platform = [NSString stringWithCString:machine encoding:NSUTF8StringEncoding];
    free(machine);

    NSString * ending = [platform substringFromIndex:[platform length]-3];
    double convertedNumber = [[ending stringByReplacingOccurrencesOfString:@"," withString:@"."] doubleValue];

//Devices listed here: https://***.com/questions/19584208/identify-new-iphone-model-on-xcode-5-5c-5s

    if ([platform containsString:@"iPhone"]) {
        if (convertedNumber >= 7.1) { // 6 and above
            return YES;
        }else{
            return NO; //less than a 6 (ie 5S and below)
        }
    }else if ([platform containsString:@"iPad"]){
        if (convertedNumber >= 5.3) { //iPad Air 2 and above
            return YES;
        }else{
            return NO; //iPad Mini 3 and below
        }
    }

    //Failsafe
    return NO;
}

注意。由于 containsString ，这将在小于8的iOS版本上崩溃。要支持< 8.0，请尝试使用以下代码重新拟合此函数https://***.com/a/26416172/1197723

Note. Due to having containsString, this will crash on iOS versions less than 8. To support <8.0, try using the following code to retro-fit this function https://***.com/a/26416172/1197723

玩得开心！
