以下代码的输出将是什么：

NSString *deviceType = [UIDevice currentDevice].model;
NSLog(@"Device Type: %@", deviceType);

在 iPhone 4 中，它将打印“iPhone”，但在 iPhone 4S 或 iPhone 5 中，输出会是什么？我没有 iPhone 4S 或 5 设备。但我需要知道它才能在所有版本的 iPhone 中实现通话功能。

谢谢。

in iPhone 4, it will print "iPhone" but in iPhone 4S or iPhone 5 what will be the output?

Also "iPhone".

UIDevice 没有帮助

#include <sys/types.h>
#include <sys/sysctl.h>

- (NSString *)deviceModel
{
    NSString *deviceModel = nil;
    char buffer[32];
    size_t length = sizeof(buffer);
    if (sysctlbyname("hw.machine", &buffer, &length, NULL, 0) == 0) {
        deviceModel = [[NSString alloc] initWithCString:buffer encoding:NSASCIIStringEncoding];
    }
    return [deviceModel autorelease];
}

我也不知道 5 的常数，但我知道它们是独一无二的：

if ([platform isEqualToString:@"iPhone1,1"])    return @"iPhone 1G";
if ([platform isEqualToString:@"iPhone1,2"])    return @"iPhone 3G";
if ([platform isEqualToString:@"iPhone2,1"])    return @"iPhone 3GS";
if ([platform isEqualToString:@"iPhone3,1"])    return @"iPhone 4";
if ([platform isEqualToString:@"iPhone3,3"])    return @"Verizon iPhone 4";
if ([platform isEqualToString:@"iPhone4,1"])    return @"iPhone 4S";
if ([platform isEqualToString:@"iPod1,1"])      return @"iPod Touch 1G";
if ([platform isEqualToString:@"iPod2,1"])      return @"iPod Touch 2G";
if ([platform isEqualToString:@"iPod3,1"])      return @"iPod Touch 3G";
if ([platform isEqualToString:@"iPod4,1"])      return @"iPod Touch 4G";
if ([platform isEqualToString:@"iPad1,1"])      return @"iPad";
if ([platform isEqualToString:@"iPad2,1"])      return @"iPad 2 (WiFi)";
if ([platform isEqualToString:@"iPad2,2"])      return @"iPad 2 (GSM)";
if ([platform isEqualToString:@"iPad2,3"])      return @"iPad 2 (CDMA)";
if ([platform isEqualToString:@"iPad2,4"])      return @"iPad 2";
if ([platform isEqualToString:@"iPad3,1"])      return @"iPad-3G (WiFi)";
if ([platform isEqualToString:@"iPad3,2"])      return @"iPad-3G (4G)";
if ([platform isEqualToString:@"iPad3,3"])      return @"iPad-3G (4G)";
if ([platform isEqualToString:@"i386"])         return @"Simulator";
if ([platform isEqualToString:@"x86_64"])       return @"Simulator";

电话 5 GSM - iPhone5,1

iPhone 5 CDMA - iPhone5,2

iPod 5 - iPod5,1

如果您试图区分 iPhone4/4S 和 iPhone5，您应该检查屏幕尺寸，而不是设备型号。
