After upgrading to xcode 7, I found a strange problem. When I call [[UIScreen mainScreen] scale] on iPhone6+ simulator, it returns 3.0, but it returns 2.0 on iPhone 6+ real device.
Is this a bug or it will also return 3.0 on iPhone 6s+ real device? since I haven't got the real iPhone 6s+, cannot test it yet.
PS. If I don't set "App Icons and Launch Images"->"Launch Screen File", [[UIScreen mainScreen] bounds].size will return 320x480, but if set "Launch Screen File", it will return 414x736, is there any documents for this problem?
