ios - 如何检测当前正在运行的应用程序是否是从应用程序商店安装的？

Question

在 iOS 中有没有办法以编程方式检查当前正在运行的应用程序是否是从 iOS App Store 安装的？这与通过 Xcode、TestFlight 或任何非官方分发源运行的应用形成对比。

这是在无法访问应用源代码的 SDK 的上下文中。

要清楚 - 我正在寻找一些签名，可以这么说，给应用程序(大概是苹果)，在不依赖任何预处理器标志或其他构建配置的情况下，任何应用程序都可以在运行时访问.

Answer 1

从 App Store 下载的应用程序有一个商店添加的 iTunesMetadata.plist 文件:

NSString *file=[NSHomeDirectory() stringByAppendingPathComponent:@"iTunesMetadata.plist"];
if ([[NSFileManager defaultManager] fileExistsAtPath:file]) {
    // probably a store app
}

也许您可能想检查此文件是否存在。

更新:

在 iOS8 中，应用程序包已被移动。根据 @silyevsk 的说法，plist 现在比 [新应用程序主包路径] 高一级，位于/private/var/mobile/Containers/Bundle/Application/4A74359F-E6CD-44C9-925D-AC82E‌‌ B5EA837/iTunesMetadata.plist，不幸的是，无法从应用程序访问它(权限被拒绝)

看来检查收据名称会有帮助。必须注意，此解决方案略有不同:它不返回我们是否正在运行 App Store 应用程序，而是返回我们是否正在运行测试版 Testflight 应用程序。这可能有用也可能没用，具体取决于您的上下文。

最重要的是，这是一个非常脆弱的解决方案，因为收据名称可能随时更改。无论如何我都会报告它，以防你没有其他选择:

// Objective-C
BOOL isRunningTestFlightBeta = [[[[NSBundle mainBundle] appStoreReceiptURL] lastPathComponent] isEqualToString:@"sandboxReceipt"];

// Swift
let isRunningTestFlightBeta = NSBundle.mainBundle().appStoreReceiptURL?.lastPathComponent=="sandboxReceipt"

HockeyKit 是如何做到的

通过组合各种检查，您可以猜测应用程序是在模拟器中、在 Testflight 构建中还是在 AppStore 构建中运行。

这是 HockeyKit 的一个片段:

BOOL bit_isAppStoreReceiptSandbox(void) {
#if TARGET_OS_SIMULATOR
  return NO;
#else
  NSURL *appStoreReceiptURL = NSBundle.mainBundle.appStoreReceiptURL;
  NSString *appStoreReceiptLastComponent = appStoreReceiptURL.lastPathComponent;
  
  BOOL isSandboxReceipt = [appStoreReceiptLastComponent isEqualToString:@"sandboxReceipt"];
  return isSandboxReceipt;
#endif
}

BOOL bit_hasEmbeddedMobileProvision(void) {
  BOOL hasEmbeddedMobileProvision = !![[NSBundle mainBundle] pathForResource:@"embedded" ofType:@"mobileprovision"];
  return hasEmbeddedMobileProvision;
}

BOOL bit_isRunningInTestFlightEnvironment(void) {
#if TARGET_OS_SIMULATOR
  return NO;
#else
  if (bit_isAppStoreReceiptSandbox() && !bit_hasEmbeddedMobileProvision()) {
    return YES;
  }
  return NO;
#endif
}

BOOL bit_isRunningInAppStoreEnvironment(void) {
#if TARGET_OS_SIMULATOR
  return NO;
#else
  if (bit_isAppStoreReceiptSandbox() || bit_hasEmbeddedMobileProvision()) {
    return NO;
  }
  return YES;
#endif
}

BOOL bit_isRunningInAppExtension(void) {
  static BOOL isRunningInAppExtension = NO;
  static dispatch_once_t checkAppExtension;
  
  dispatch_once(&checkAppExtension, ^{
    isRunningInAppExtension = ([[[NSBundle mainBundle] executablePath] rangeOfString:@".appex/"].location != NSNotFound);
  });
  
  return isRunningInAppExtension;
}

用户 halileohalilei 报告说“这不再适用于 iOS10 和 Xcode 8”。我没有验证这一点，但请检查更新的 HockeyKit 源代码(参见函数 bit_currentAppEnvironment):

随着时间的推移，上面的类已经被修改，它似乎也可以处理 iOS10。
