检测IOS设备类型

Question

我从这里找到了解决方案: 使用iPhone SDK确定设备（iPhone、iPod Touch）

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

但是很明显，这个库已经过时了。我在列表中找不到iPhone 5和新iPad等设备。

有人知道如何找到完整和更新的列表吗？

非常感谢。

Answer 1

你可以使用以下条件轻松检测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]
 }

我的答案：检测设备类型

请不要使用==来比较float，这是不安全的。你最好使用[[UIScreen mainScreen] bounds].size.height > 567。 - user529758

有传言称下一代iPod将拥有5英寸的屏幕，因此如果您想为未来制作应用程序，这将会带来一些小问题。 - amar

@H2CO3 是正确的！或者将其与浮点字面量进行比较，[[UIScreen mainScreen] bounds].size.height == 568.0f - Rukshan

如果 iPhone 应用在 iPad 上以框架方式运行，则 [[UIScreen mainScreen] bounds].size.height > 567 不起作用。 - heximal

Answer 2

这个很好用：

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

这是更新后的版本：https://gist.github.com/1323251。 新设备发布后，我会继续更新。

Answer 4

仅作为@Mohammad Kamran Usmani回答的补充。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");
    }
}

请使用以下代码：

#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";
}

请使用更易读的 if (stuff != bar)，而不是 if (!(stuff == bar))。谢谢！ - user529758

抱歉，我的错，以后会注意的。 - amar

我和其他人正在GitHub上维护代码，请从那里获取最新的代码。我们不断地将新设备添加到列表中。

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";

你可以使用以下代码。

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
}

比较浮点数值是非常不安全的。根据 CPU 的心情，你会发现在那些 if 条件语句中会得到很多错误的负值，导致它们错误地进入“else”中。 - mylogon

这是我想出来的一种方法，专注于屏幕测量功能的关键设备。这是一种快速确定您所需内容的方法。它可以检测到iPhone 5和第五代iPod touch。

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

-(void)yourCustomFunctionThatNeedsToKnowDeviceType

    NSLog(@"device type = %i",[self getDeviceType]);

    switch ([self getDeviceType])

            NSLog(@"This device is one of the following: iPad 3, iPad 4");
