Try opening your .xib file, delete the connection, delete the method in the header, and then recreate it. When you create the action choose the 1-argument version (the one that takes a "sender" argument). It should look something like this in the Objective-C header:

-(void)btnTransfer_TouchUpInside:(id)sender;

Iam using story board and i can not find .xib files in my project
Edit:
I've opened storyboard file in xml editor and added missing ":" in button declaration in its connection region
this
selector="btnUpdateTouchUpInside"
changed to
selector="btnUpdateTouchUpInside:"
