ios - Error when presenting different storyboard programmatically -

-

i have app 2 storyboards. 1 of them main app stuff, , 1 setup storyboard set user profile. right now, have set main interface setup.storyboard. in first view controller in storyboard, in -viewwillappear:animated method, checks nsuserdefault see if setup complete. if is, execute code.

- (void)viewwillappear:(bool)animated {     [super viewwillappear:animated];      if ([[nsuserdefaults standarduserdefaults] boolforkey:@"userhascompletedsetup"]) {          uistoryboard *sb = [uistoryboard storyboardwithname:@"main" bundle:nil];         swrevealviewcontroller *vc = [sb instantiateviewcontrollerwithidentifier:@"initialvc"];         [self presentviewcontroller:vc animated:yes completion:null];     } }

i error warning: attempt present <swrevealviewcontroller: 0x7ff20a595220> on <mposetuponeviewcontroller: 0x7ff20a720b80> view not in window hierarchy!

(i using swrevealviewcontroller in app menu.)

i error, , view controller not switch. there way can switch storyboards based on nsuserdefault? maybe in appdelegate?

just move code viewdidappear:. in viewwillappear:, view not in interface yet (that "will" means), there nothing present from.

what isshellcommand property , how should use it? the description when hovering says: "specifies whether command shell command or external programm. defaults false if omitted" and in https://code.visualstudio.com/docs/editor/tasks mention in example with: "we want run gulp command in shell (vs code directly executing it) used isshellcommand" so difference between shell command vs external program? does running isshellcommand = false mean vscode not "directly executing it" meaning run "command" , don´t listen output (because ran external command?) in turn means cannot use problem matchers. or if setting isshellcommand = true mean vscode "directly executing it" , keep track of , listen output generated can use problem matchers etc integrate vscode? considering example below using tsc compile typescript project: c:\users\j\code\vscode-project>where tsc c:\program files (x86)\microsoft sdks\typescript\1.4\tsc.exe ...
