if ([[NSBundle mainBundle] pathForResource:@"embedded" ofType:@"mobileprovision"]) {
    // 下载自TestFlight

BOOL isDownLoadFromTestFlightBeta = [[[[NSBundle mainBundle] appStoreReceiptURL] lastPathComponent] isEqualToString:@"sandboxReceipt"];

Swift

/// 是否是 testflight包
public static var isTestFlight: Bool {
    return isAppStoreReceiptSandbox && !hasEmbeddedMobileProvision
 }
/// 是否是 Appstore 包
 public static var isAppStore: Bool {
    return isAppStoreReceiptSandbox || hasEmbeddedMobileProvision ? false : true
 }
 fileprivate static var isAppStoreReceiptSandbox: Bool {
    return Bundle.main.appStoreReceiptURL?.lastPathComponent == "sandboxReceipt"
 }
 fileprivate static var hasEmbeddedMobileProvision: Bool {
    return Bundle.main.path(forResource: "embedded", ofType: "mobileprovision") != nil
