"How to detect spyware: Can you use 'Iphone Analytics' logs to discover if someone has hacked or is remotely controlling your device?

About a Hacked iPhone:
Unfortunately, there is no way to determine if it has been hacked, unless you know that it has been jailbroken. The only way for an iPhone to have hacked is if it has been jail broken.
Resetting to Factory Settings:
If you are so concerned, then reset you iPhone to factory settings, as if you were to sell it. Go here: What to do Before you Sell, Give Away, or Trade in your iPhone, iPad, or iPod touch - Apple Support. Perform as instructed there, including the backup creation and iCloud logout.
