ios - Change Storyboard View using Seague -
i have following code checks connection server, , depending on want change views if no connection found.
nsstring *connect = [nsstring stringwithcontentsofurl:[nsurl urlwithstring:@"http://myserver.com"] encoding:nsutf8stringencoding error:nil]; if (connect == null) { [self performseguewithidentifier:@"network_failure" sender:self]; } else { // other code here }
my problem not change views. have added storyboard segue between 2 views identifier of network_failure
. not have navigation controller or that, problem?
thanks help!
no not problem.
first of all, in objectivec
exists nil
object oriented null. must use that. so:
if(connect == nil)
or better:
if(!connect)
so due fact nil
not same of null
, probably code does't enter in if scope.
you have been able discover breakpoint.
anyway:
be sure set trigger segue (line) 2 view controller, , name network_failure
(that not best name. should instead view1toview2
) as, modality modal
, not push
because haven't navigationcontroller
.
