Detect if iOS App is Downloaded from Apple's Testflight [duplicate]

Answer 1

This works:

if ([[NSBundle mainBundle] pathForResource:@"embedded" ofType:@"mobileprovision"]) {
    // TestFlight
} else {
    // App Store (and Apple reviewers too)
}

Update

The above method doesn't seem to work anymore, Apple changed the way they sign TestFlight builds. This does work however:

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