这取决于你所说的越狱是什么意思。 在简单的情况下，您应该能够查看 Cydia 是否已安装并进行操作 - 就像

NSString *filePath = @"/Applications/Cydia.app";
if ([[NSFileManager defaultManager] fileExistsAtPath:filePath])
{
   // do something useful
}

对于被黑客攻击的内核一样，它涉及更多一点（很多）。

It depends what you mean by jailbreak. In the simple case, you should be able to see if Cydia is installed and go by that - something like

NSString *filePath = @"/Applications/Cydia.app";
if ([[NSFileManager defaultManager] fileExistsAtPath:filePath])
{
   // do something useful
}

For hacked kernels, it's a little (lot) more involved.

这是一个代码，结合了我针对此需求找到的一些答案，将为您提供更高的成功率：

BOOL isJailbroken()
{
#if !(TARGET_IPHONE_SIMULATOR)

   if ([[NSFileManager defaultManager] fileExistsAtPath:@"/Applications/Cydia.app"] ||
       [[NSFileManager defaultManager] fileExistsAtPath:@"/Library/MobileSubstrate/MobileSubstrate.dylib"] ||
       [[NSFileManager defaultManager] fileExistsAtPath:@"/bin/bash"] ||
       [[NSFileManager defaultManager] fileExistsAtPath:@"/usr/sbin/sshd"] ||
       [[NSFileManager defaultManager] fileExistsAtPath:@"/etc/apt"] ||
       [[NSFileManager defaultManager] fileExistsAtPath:@"/private/var/lib/apt/"] ||
       [[UIApplication sharedApplication] canOpenURL:[NSURL URLWithString:@"cydia://package/com.example.package"]])  {
         return YES;
   }

   FILE *f = NULL ;
   if ((f = fopen("/bin/bash", "r")) ||
      (f = fopen("/Applications/Cydia.app", "r")) ||
      (f = fopen("/Library/MobileSubstrate/MobileSubstrate.dylib", "r")) ||
      (f = fopen("/usr/sbin/sshd", "r")) ||
      (f = fopen("/etc/apt", "r")))  {
         fclose(f);
         return YES;
   }
   fclose(f);

   NSError *error;
   NSString *stringToBeWritten = @"This is a test.";
   [stringToBeWritten writeToFile:@"/private/jailbreak.txt" atomically:YES encoding:NSUTF8StringEncoding error:&error];
   [[NSFileManager defaultManager] removeItemAtPath:@"/private/jailbreak.txt" error:nil];
   if(error == nil)
   {
      return YES;
   }

#endif

   return NO;
}

This is a code that combine some answers I found for this need, and will give you much higher success rate :

BOOL isJailbroken()
{
#if !(TARGET_IPHONE_SIMULATOR)

   if ([[NSFileManager defaultManager] fileExistsAtPath:@"/Applications/Cydia.app"] ||
       [[NSFileManager defaultManager] fileExistsAtPath:@"/Library/MobileSubstrate/MobileSubstrate.dylib"] ||
       [[NSFileManager defaultManager] fileExistsAtPath:@"/bin/bash"] ||
       [[NSFileManager defaultManager] fileExistsAtPath:@"/usr/sbin/sshd"] ||
       [[NSFileManager defaultManager] fileExistsAtPath:@"/etc/apt"] ||
       [[NSFileManager defaultManager] fileExistsAtPath:@"/private/var/lib/apt/"] ||
       [[UIApplication sharedApplication] canOpenURL:[NSURL URLWithString:@"cydia://package/com.example.package"]])  {
         return YES;
   }

   FILE *f = NULL ;
   if ((f = fopen("/bin/bash", "r")) ||
      (f = fopen("/Applications/Cydia.app", "r")) ||
      (f = fopen("/Library/MobileSubstrate/MobileSubstrate.dylib", "r")) ||
      (f = fopen("/usr/sbin/sshd", "r")) ||
      (f = fopen("/etc/apt", "r")))  {
         fclose(f);
         return YES;
   }
   fclose(f);

   NSError *error;
   NSString *stringToBeWritten = @"This is a test.";
   [stringToBeWritten writeToFile:@"/private/jailbreak.txt" atomically:YES encoding:NSUTF8StringEncoding error:&error];
   [[NSFileManager defaultManager] removeItemAtPath:@"/private/jailbreak.txt" error:nil];
   if(error == nil)
   {
      return YES;
   }

#endif

   return NO;

+(BOOL)isJailbroken {
    NSURL* url = [NSURL URLWithString:@"cydia://package/com.example.package"];
    return [[UIApplication sharedApplication] canOpenURL:url];
}

普通手机不允许检查文件路径/Applications/Cydia.app？ 我从未听说过苹果公司检测到这一点并拒绝其应用程序，但苹果公司是不可预测的。 Cydia 有 一个 URL 方案 cydia://，可以使用 UIApplication canOpenURL: 进行合法检查

+(BOOL)isJailbroken {
    NSURL* url = [NSURL URLWithString:@"cydia://package/com.example.package"];
    return [[UIApplication sharedApplication] canOpenURL:url];
}

Checking the file path /Applications/Cydia.app is not allowed on a normal phone? I've never heard of Apple detecting this and rejecting an app for it, but Apple is unpredictable. Cydia has a URL scheme cydia:// which can be legally checked with UIApplication canOpenURL:

检查内核是否损坏并没有那么复杂。

越狱使得内核对签名代码的签名检查始终报告代码签名正确，未破解的手机无法运行签名错误的代码。

因此，请在应用程序中包含一个签名错误的单独可执行文件。 它可能只是一个具有 main() 和返回值的 3 行程序。 编译可执行文件而不进行代码签名（在“项目设置”->“构建”中将其关闭），并使用“codesign”命令行实用程序使用不同的密钥对其进行签名。

让您的应用程序执行单独的可执行文件。 如果您的程序在运行带有错误签名的单独可执行文件时无法获取返回值，那么它肯定会被监禁。 如果单独的可执行文件返回 A-OK，则手机肯定已越狱。

Checking if the kernel is broken isn't THAT much more involved.

Jailbreaking makes the kernel's signature check of signed code always report that code is signed correctly, unbroken phones cannot run code with a bad signature.

So, include a separate executable in the app with a bad signature. It could just be a 3-line program that has main() and a return value. Compile the executable without code signing (turn it off in Project Settings->Build) and sign it with a different key using the "codesign" commandline utility.

Have your app exec the separate executable. If your program can't get the return value when running the separate executable with the bad sig, it's definitely jailed. If the separate executable returns A-OK, the phone is definitely jailbroken.

您可以通过检查以下内容来检测设备是否越狱：

  • Cydia 已安装
  • 验证某些系统路径
  • 执行沙箱完整性检查
  • 执行符号链接验证
  • 验证您是否在沙箱之外创建和写入文件

有一个开源库 I根据各种文章和书籍创建。 在 GitHub 上尝试！

You can detect if a device is JailBroken or not by checking for the following:

  • Cydia is installed
  • Verify some of the system paths
  • Perform a sandbox integrity check
  • Perform symlink verification
  • Verify whether you create and write files outside your Sandbox

There is an open source library I created from various articles and books. Try it out on GitHub!

我所知道的最复杂的方法是使用 objc_copyImageNames() 函数。 它返回当前加载的库的列表，并且由于大多数人在越狱设备上都有 MobileSubstrate，并且大多数 iAP 破解工具都依赖于它，因此至少会显示一些 MobileSubstrate 库。

The most sophisticated method I know is using objc_copyImageNames() function. It returns a list of currently loaded libraries and since most people have MobileSubstrate on jailbroken devices and most iAP crack tools depend on it, at least some MobileSubstrate libraries will show up.

对于 Swift 4 及以上版本，请使用以下代码：
在appdelegate中添加以下代码：

private func getJailbrokenStatus() -> Bool {
    if TARGET_IPHONE_SIMULATOR != 1 {
        // Check 1 : existence of files that are common for jailbroken devices
        if FileManager.default.fileExists(atPath: "/Applications/Cydia.app")
            || FileManager.default.fileExists(atPath: "/Library/MobileSubstrate/MobileSubstrate.dylib")
            || FileManager.default.fileExists(atPath: "/bin/bash")
            || FileManager.default.fileExists(atPath: "/usr/sbin/sshd")
            || FileManager.default.fileExists(atPath: "/etc/apt")
            || FileManager.default.fileExists(atPath: "/private/var/lib/apt/")
            || UIApplication.shared.canOpenURL(URL(string:"cydia://package/com.example.package")!) {
            return true
        }
        // Check 2 : Reading and writing in system directories (sandbox violation)
        let stringToWrite = "Jailbreak Test"
        do {
            try stringToWrite.write(toFile:"/private/JailbreakTest.txt", atomically:true, encoding:String.Encoding.utf8)
            //Device is jailbroken
            return true
        } catch {
            return false
        }
    }
    else {
        return false
    }
}

在Appdelegate方法内部，编写如下代码

func applicationDidBecomeActive (_ application: UIApplication) {
    
    if getJailbrokenStatus() {
        let alert = UIAlertController(title: LocalizedKeys.Errors.jailbreakError, message: LocalizedKeys.Errors.jailbreakErrorMessage, preferredStyle: UIAlertController.Style.alert)
        let jailBrokenView = UIViewController()
        
        jailBrokenView.view.frame = UIScreen.main.bounds
        jailBrokenView.view.backgroundColor = .white
        self.window?.rootViewController = jailBrokenView
        jailBrokenView.present(alert, animated: true, completion: nil)
    }
    
    if #available(iOS 11.0, *) {
        if !UIScreen.main.isCaptured {
            DispatchQueue.main.async {
                self.blockImageView.removeFromSuperview()
            }
        }
    }
}

Please use following code for Swift 4 and above:
Add the following code in the appdelegate:

private func getJailbrokenStatus() -> Bool {
    if TARGET_IPHONE_SIMULATOR != 1 {
        // Check 1 : existence of files that are common for jailbroken devices
        if FileManager.default.fileExists(atPath: "/Applications/Cydia.app")
            || FileManager.default.fileExists(atPath: "/Library/MobileSubstrate/MobileSubstrate.dylib")
            || FileManager.default.fileExists(atPath: "/bin/bash")
            || FileManager.default.fileExists(atPath: "/usr/sbin/sshd")
            || FileManager.default.fileExists(atPath: "/etc/apt")
            || FileManager.default.fileExists(atPath: "/private/var/lib/apt/")
            || UIApplication.shared.canOpenURL(URL(string:"cydia://package/com.example.package")!) {
            return true
        }
        // Check 2 : Reading and writing in system directories (sandbox violation)
        let stringToWrite = "Jailbreak Test"
        do {
            try stringToWrite.write(toFile:"/private/JailbreakTest.txt", atomically:true, encoding:String.Encoding.utf8)
            //Device is jailbroken
            return true
        } catch {
            return false
        }
    }
    else {
        return false
    }
}

Inside Appdelegate methods, write code as below

func applicationDidBecomeActive (_ application: UIApplication) {
    
    if getJailbrokenStatus() {
        let alert = UIAlertController(title: LocalizedKeys.Errors.jailbreakError, message: LocalizedKeys.Errors.jailbreakErrorMessage, preferredStyle: UIAlertController.Style.alert)
        let jailBrokenView = UIViewController()
        
        jailBrokenView.view.frame = UIScreen.main.bounds
        jailBrokenView.view.backgroundColor = .white
        self.window?.rootViewController = jailBrokenView
        jailBrokenView.present(alert, animated: true, completion: nil)

我不知道为此存在任何“API”。 如果有的话，那么越狱屏蔽产品会很快掩盖它们。

正如很多人指出的那样，这是一场猫捉老鼠的游戏。 当两位玩家都成为专家之后，一切就取决于谁先走一步。 （拿着设备的人。）

我在 Zdziarski 的新书《Hacking and Securing iOS Apps》中发现了许多检测越狱的好建议。 （就我个人而言，我为 O'Reilly 电子书支付了更多费用，因为它们允许复制和粘贴。）

不，我不隶属于出版商。 但我确实发现这是一本好书。 我不喜欢仅仅发布黑客的错误以便他们可以修复它们，所以我想我应该参考这本书。

I am not aware of any "APIs" that exist for this. If there were, then a jailbreak-masking product would quickly cover them up.

As lots of people point out, it is a cat-and-mouse game. And after both players become expert, it all comes down to who gets the first move. (Person holding the device.)

I found many good suggestions for detecting jailbreak in Zdziarski's new book "Hacking and Securing iOS Apps". (Personally, I paid more for the O'Reilly eBook because they permit copy-and-paste.)

No, I am not affiliated with the publishers. But I did find it a good book. I don't like to just publish hackers' mistakes so they can fix them, so I thought I'd point to the book.

尝试通过您的应用程序执行未签名的代码。

越狱设备通常具有以下特征：

  • 运行未签名的代码
  • 已安装 Cydia
  • 已越狱文件
  • 对整个文件系统具有完全读写访问权限
  • 某些系统文件将被修改（内容，因此 sha1 与原始文件不匹配）
  • 坚持特定版本（可越狱版本）

仅仅检查文件是否存在进行越狱检测注定会失败。
这些检查很容易被绕过。

Try executing unsigned code through your application.

A jailbroken devices usually has the following characteristics:

  • run unsigned code
  • has Cydia installed
  • has jailbreak files
  • full r/w access to the whole filesystem
  • some system files will have been modified (content and so sha1 doesn't match with original files)
  • stuck to specific version (jailbreakable version)

Just checking file existence for jailbreak detection is doomed to fail.
These checks are easy to bypass.

尝试查找 cydia 或越狱设备创建的文件。 或者尝试写入应用程序黑盒之外的文件。 如果您成功做到这一点，则该设备已被入侵/越狱:)

- (BOOL)jailbroken
{
    NSFileManager * fileManager = [NSFileManager defaultManager];
    return [fileManager fileExistsAtPath:@"/private/var/lib/apt/"];
}

Try to find a file which cydia or jailbroken device create. Or try to write in a file outside the app's blackbox. If you succeed to do that, the device is compromised/jailbroken :)

- (BOOL)jailbroken

    NSFileManager * fileManager = [NSFileManager defaultManager];

Apple 目前不提供检查越狱的合法方法。

您可以尝试自定义工具来执行此操作，例如JailbreakDetectionService

Apple don't provide a legal way to check for jailbreak at this moment.

You can try custom tools to do this, like JailbreakDetectionService
. And may read a modern way to check for jailbreak.

Also maybe you get an info about validating device via Firebase or Apple

In my experience, the lib IOSSecuritySuite provides falsepositive checks for jailbreak, but it also can help you.

Common jailbreak file paths:

let jailbreakFilePaths = [
        "/usr/sbin/frida-server",
        "/etc/apt/sources.list.d/electra.list",
        "/etc/apt/sources.list.d/sileo.sources",
        "/.bootstrapped_electra",
        "/usr/lib/libjailbreak.dylib",
        "/jb/lzma",
        "/.cydia_no_stash",
        "/.installed_unc0ver",
        "/jb/offsets.plist",
        "/usr/share/jailbreak/injectme.plist",
        "/etc/apt/undecimus/undecimus.list",
        "/var/lib/dpkg/info/mobilesubstrate.md5sums",
        "/Library/MobileSubstrate/MobileSubstrate.dylib",
        "/jb/jailbreakd.plist",
        "/jb/amfid_payload.dylib",
        "/jb/libjailbreak.dylib",
        "/usr/libexec/cydia/firmware.sh",
        "/var/lib/cydia",
        "/etc/apt",
        "/private/var/lib/apt",
        "/private/var/Users/",
        "/var/log/apt",
        "/private/var/stash",
        "/private/var/lib/cydia",

这是我的解决方案：
第 1 步

extension UIDevice {
    func isJailBroken() -> Bool {
        let cydiaPath = "/Applications/Cydia.app"
        let aptPath = "/private/var/lib/apt/"
        if FileManager.default.fileExists(atPath: cydiaPath) || FileManager.default.fileExists(atPath: aptPath) {
            return true
        }
        return false
    }
}

第 2 步：在启动屏幕视图控制器（或您第一次调用的任何 VC）内的 viewDidLoad() 中调用它：

       // show a blank screen or some other view controller
       let viewController = UIDevice.current.isJailBroken() ? JailBrokenViewController() : NextViewController()
       self.navigationController?.present(viewController, animated: true, completion:nil)

Here's my solutions:
Step 1

extension UIDevice {
    func isJailBroken() -> Bool {
        let cydiaPath = "/Applications/Cydia.app"
        let aptPath = "/private/var/lib/apt/"
        if FileManager.default.fileExists(atPath: cydiaPath) || FileManager.default.fileExists(atPath: aptPath) {
            return true
        }
        return false
    }
}

Step 2: Call it inside viewDidLoad() inside your launch screen view controller(or whatever VC you are calling for the first time):

       // show a blank screen or some other view controller
       let viewController = UIDevice.current.isJailBroken() ? JailBrokenViewController() : NextViewController()
       self.navigationController?.present(viewController, animated: true, completion:nil)
