After signing out or logging off of everything iCloud, iMessage or iTunes, go to Settings/General/Reset. At that point you have a number of choices, one of which is "Erase all content and settings". Selecting and executing that selection will securely erase all user content from the phone and return the phone to the condition it was in when you first bought it but with the current operating system still installed. Does that completely erase all user data from the phone? For all intents and purposes, yes. You can sell the phone with every confidence that your data will remain only with you. However, if you are totally paranoid, I'm sure somebody like the FBI, NSA, or any of those other government acronyms can get it back off of your device in spite of that, but John Q. Hacker.......NOPE.

The only sure method to remove all data is to physically, totally destroy the device, nuke the remaining pieces in a microwave, subject what's left to a direct lightning strike and then place the leftovers in hydrofluoric acid for a few years. That should do it.

I should have added that turning off Find My iPhone followed by turning off iCloud before wiping out the phone, is essential to the next person who gets the phone being able to use the it. Otherwise they will need your iTunes username and password to activate the phone because of the security features of iOS7.

I heard this method will not permanently erase iPhone data, it still can be recovered by some data recovery,

The fastest way to delete iPhone photos is to open the photos app, tap Photos on the bottom left, enter the Moments view, tap Select, then select photos you want to delete and remove.
This isn't what the OP asked and this thread is nearly two years old. He wanted to know how to erase all content from the phone prior to sale. The question has already been answered.

How to erase messages ,contacts,photos from iPhone can be difficult for us , because no matter how we remove them , the messages and contacts are back with some recovery tool ,
