ios - Handling NSError with error.code -


i trying handle specific nserrors uialertview none of codes in if statements called when webview didfailloadwitherror called. below condition statement:

 - (void)webview:(uiwebview *)webview didfailloadwitherror:(nserror *)error { loadfailedbool = yes; nslog(@"error code %ld", (long)[error code]); if ([error code] != -999) {     //loading cancelled , 1 initiated. don't show alert     return; } else if ([error code] == nsurlerrortimedout || [error code] == kcfurlerrortimedout) {     //connection timed out     uialertview *alert = [[uialertview alloc] initwithtitle:@"alert" message:@"network connection timed out" delegate:self cancelbuttontitle:@"ok" otherbuttontitles:nil, nil];     [alert show];     alert.tag = 1; } else if ([error code] == -1005) {     //connection lost     uialertview *alert = [[uialertview alloc] initwithtitle:@"alert" message:@"network connection host lost" delegate:self cancelbuttontitle:@"ok" otherbuttontitles:nil, nil];     [alert show];     alert.tag = 1; } else if ([error code] == kcfurlerrornotconnectedtointernet || [error code] == -1009) {     //no internet connection     nslog(@"error here");     uialertview *alert = [[uialertview alloc] initwithtitle:@"alert" message:@"looks not connected internet" delegate:self cancelbuttontitle:@"ok" otherbuttontitles:nil, nil];     [alert show];     alert.tag = 1; } else if ([error.domain isequaltostring:@"webkiterrordomain"] && error.code == 102) {      return;   } } 

my question is, how condition called because log prints -1009 when there no internet. thanks

the thing never past line:

if ([error code] != -999) {     return; } 

so if error code -1009, or anything -999, it's late - have said return , whole thing over. later code won't execute.
