Question

我从这里找到了解决方案： Determine device (iPhone, iPod Touch) with iPhone SDK

从链接中，它建议使用库https://gist.github.com/1323251

但显然图书馆已经过时了。我在列表中找不到iPhone 5和新iPad等。

有谁知道如何找到已完成和更新的列表？

非常感谢你。

Answer 1

您可以在以下条件下轻松检测iphone，iphone5和iPad： -

 if([[UIDevice currentDevice]userInterfaceIdiom]==UIUserInterfaceIdiomPhone)
 {
     if ([[UIScreen mainScreen] bounds].size.height == 568.0f)
     {


     }
     else
     {
         //iphone 3.5 inch screen
     }
 }
 else
 {
        //[ipad]
 }

Answer 2

以下是https://gist.github.com/1323251的更新版本。我会在新设备发布时保持更新。

Answer 3

这很好用：

if([UIDevice currentDevice].userInterfaceIdiom==UIUserInterfaceIdiomPad) {
    NSLog(@"IPAD");
}else{
     NSLog(@"IPHONE");
}

Answer 4

刚刚加入@Mohammad Kamran Usmani回答。更具体的iPhone类型：

@import UIKit;

//Check which iPhone it is
double screenHeight = [[UIScreen mainScreen] bounds].size.height;
if(UI_USER_INTERFACE_IDIOM()==UIUserInterfaceIdiomPad)
{
    NSLog(@"All iPads");
} else if (UI_USER_INTERFACE_IDIOM()== UIUserInterfaceIdiomPhone)
{
    if(screenHeight == 480) {
        NSLog(@"iPhone 4/4S");
        smallFonts = true;
    } else if (screenHeight == 568) {
        NSLog(@"iPhone 5/5S/SE");
        smallFonts = true;
    } else if (screenHeight == 667) {
        NSLog(@"iPhone 6/6S");
    } else if (screenHeight == 736) {
        NSLog(@"iPhone 6+, 6S+");
    } else {
        NSLog(@"Others");
    }
}

Answer 5

使用以下代码：

#import <sys/utsname.h>

- (NSString *)machineName
{
    struct utsname systemInfo;
    uname(&systemInfo);
    NSString *temp = [NSString stringWithCString:systemInfo.machine
                                        encoding:NSUTF8StringEncoding];

    if ([temp rangeOfString:@"iPod"].location != NSNotFound)
    {
        return @"iPod";
    }

    if ([temp rangeOfString:@"iPad"].location != NSNotFound)
    {
        return @"iPad";
    }

    if ([temp rangeOfString:@"iPhone"].location != NSNotFound)
    {
        return @"iPhone";
    }

    return @"Unknown device";
}

Answer 6

您可以使用以下代码

if(screenSize.width==2048 && screenSize.height==1536)
{
   LetterParams.DeviceType=1;//IPadRetina
}
else if(screenSize.width==2048/2 && screenSize.height==1536/2)
{
   LetterParams.DeviceType=2;//IPad Non-Retina
}
else if(screenSize.width==1136 && screenSize.height==640)
{
   LetterParams.DeviceType=3;//IPhoneRetina
}
else
{
   LetterParams.DeviceType=4;//IPhone & Ipod
}

我和其他人一起维护 GitHub 上的代码，所以请从那里获取最新的代码。我们不断在列表中添加新设备。

Objective-C ：GitHub/DeviceUtil

Swift ：GitHub/DeviceGuru

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

- (NSString*)hardwareDescription {
    NSString *hardware = [self hardwareString];
    if ([hardware isEqualToString:@"iPhone1,1"]) return @"iPhone 2G";
    if ([hardware isEqualToString:@"iPhone1,2"]) return @"iPhone 3G";
    if ([hardware isEqualToString:@"iPhone3,1"]) return @"iPhone 4";
    if ([hardware isEqualToString:@"iPhone4,1"]) return @"iPhone 4S";
    if ([hardware isEqualToString:@"iPhone5,1"]) return @"iPhone 5";
    if ([hardware isEqualToString:@"iPod1,1"]) return @"iPodTouch 1G";
    if ([hardware isEqualToString:@"iPod2,1"]) return @"iPodTouch 2G";
    if ([hardware isEqualToString:@"iPad1,1"]) return @"iPad";
    if ([hardware isEqualToString:@"iPad2,6"]) return @"iPad Mini";
    if ([hardware isEqualToString:@"iPad4,1"]) return @"iPad Air WIFI";
    //there are lots of other strings too, checkout the github repo
    //link is given at the top of this answer

    if ([hardware isEqualToString:@"i386"]) return @"Simulator";
    if ([hardware isEqualToString:@"x86_64"]) return @"Simulator";

    return nil;
}

- (NSString*)hardwareString {
    size_t size = 100;
    char *hw_machine = malloc(size);
    int name[] = {CTL_HW,HW_MACHINE};
    sysctl(name, 2, hw_machine, &size, NULL, 0);
    NSString *hardware = [NSString stringWithUTF8String:hw_machine];
    free(hw_machine);
    return hardware;
}

这是我提出的一种方法，专注于屏幕测量功能的关键设备。这是确定您需要的快速方法。这将检测iPhone 5和第五代iPod触摸。

typedef enum{
   iPadRetina,iPadNoRetina,iPhoneiPod35InchRetina,iPhoneiPod35InchNoRetina,iPhoneiPod4InchRetina}DeviceType;
