-(void)myfunction {  if (!_accountstore) _accountstore = [[acaccountstore alloc] init];      acaccounttype *fbacttype = [_accountstore accounttypewithaccounttypeidentifier:acaccounttypeidentifierfacebook];       nsdictionary *options = [[nsdictionary alloc] initwithobjectsandkeys:                              (nsstring *)acfacebookappidkey, @"##########",                                (nsstring *)acfacebookpermissionskey, [nsarray arraywithobject:@"email"],                                nil];       [_accountstore requestaccesstoaccountswithtype:fbacttype options:options completion:^(bool granted, nserror *error) {                                                 nslog(@"home.m - getfbdetails - check 2");                                                 if (granted == yes) {                                                     nslog(@"success");                                                     nsarray *accounts = [_accountstore accountswithaccounttype:fbacttype];                                                     _facebookaccount = [accounts lastobject];                                                                                                         [self me];                                                } else {                                                     nslog(@"err: %@ ",error);                                                     // fail gracefully...                                               }             }      ];  }

and error: err: error domain=com.apple.accounts code=8 "the operation couldn’t completed. (com.apple.accounts error 8.)"

update: did testing , if run using acaccounttypeidentifiertwitter, prompt connect twitter accounts, supposing facebook settings ...

you have inverted objects , keys in options dictionary :

nsdictionary *options = [[nsdictionary alloc] initwithobjectsandkeys:                          @"##########",  acfacebookappidkey,                          [nsarray arraywithobject:@"email"], acfacebookpermissionskey,                          nil];

linux - xterm copying to CLIPBOARD using copy-selection causes automatic updating of CLIPBOARD upon mouse selection -

i've tried various ways coerce xterm (versions 285 , 292) copy selection clipboard clipboard whenever press ctrl-shift-c. promising way far has been, in ~/.xresources, put this: xterm*vt100.translations: #override \ ctrl shift <keypress> c: copy-selection(clipboard) \n\ ctrl shift <keypress> v: insert-selection(clipboard) ctrl-shift-v works perfectly, copying has nuance... if restart xterm, highlighting text puts things in primary clipboard; expected, proper, default behavior. if hit ctrl-shift-c, copies current selection clipboard clipboard. the bug, however, if highlight text after first time pressed ctrl-shift-c, you'll see highlighting copies both primary and clipboard. cannot figure out how stop xterm updating clipboard upon selection... , doesn't make sense me in first place. i said, @ specific point in time, copy selection clipboard... yet starts updating automatically upon selection after doing once... anyone have workaround...
