My iMessage won't open, it just crashes.

Question

I have the iPod 5 with IOS7. And recently after I sent my sister a few dozens of pictures it crashed. I thought maybe because of the overload photos I must of sent; there were a lot. So when I went back to iMessage it won't open. It just keeps crashing. I asked my sister to send me a few messages so when it shows up in my lock screen I can slide to unlock and open it, or when the banner appears when I'm on different apps comes down I'll press it from there. But nothing seems to work. My battery died, so when I rebooted it up I thought hey maybe it'll work now. But it still doesn't. I've restarted it as well but it's still the same. I went into settings and turned them off then on again to see what it may do. But it doesn't help. I'd really appreciate the help I might get, thanks for your time!

Answer 1

Try:
- Reset the iOS device. Nothing will be lost
Reset iOS device: Hold down the On/Off button and the Home button at the same time for at
least ten seconds, until the Apple logo appears.
- Reset all settings      
Go to Settings > General > Reset and tap Reset All Settings.
All your preferences and settings are reset. Information (such as contacts and calendars) and media (such as songs and videos) aren’t affected.
- Restore from backup. See:                                                
iOS: How to back up                                                                                     
- Restore to factory settings/new iOS device.             
If still problem, make an appointment at the Genius Bar of an Apple store since it appears you have a hardware problem.
