If I restore my iPhone will I lose my apps, photos and other data?

When I try to open the apps that I downloaded on my iPhone they immediately crash and return me to the home screen. I've tried switching my phone off and on and that hasn't helped and I've checked to see if all my apps are in date in the app store and it says that all my apps are in date in my app store. And these apps that I've got on my phone have always worked since i've downloaded them a year ago.
