I read why this error message happen. It said when "Outlet" is wrong,this error happen.But I do not know how to fix this.I saw outlet of PhotoSelect&PhotoSend has !,but I cannot understand this mean.What should I do?

Answer 1

The problem is the two outlets PhotoSelect and PhotoSend. You probably accidentally created these as #IBOutlet, deleted them and recreated them as #IBAction.
See how they have a ! next to them. This means that these outlets are no longer connected. So when you run you app, your storyboard cannot find those outlets in your view controller, so it crashes.
You need to remove those outlets by clicking the x.
