Attempt to present ... whose view is not in the window hierarchy - ios

Question

I developed with WinDev Mobile , which generates a project I then opened with XCode to compile .
Only in WM sharing functionality on facebook has not yet been developed, I must to develop in ObjC
I started with the code:
if ([SLComposeViewController isAvailableForServiceType:SLServiceTypeFacebook]) {
SLComposeViewController *controllerSLC = [SLComposeViewController composeViewControllerForServiceType:SLServiceTypeFacebook] ;
[controllerSLC setInitialText:myMessage];
[controllerSLC addURL:[NSURL URLWithString:myUrl]];
[controllerSLC addImage:[UIImage imageNamed:myImage]];
// NSLog (#"% #", [UIApplication sharedApplication] keyWindow.rootViewController.)
[self presentViewController:controllerSLC animated:YES completion:Nil];
controllerSLC.completionHandler = ^(SLComposeViewControllerResult result) {
NSString *output = nil;
switch(result) {
SLComposeViewControllerResultDone box:
output = # "Your tweet has-been sent" ;
status = 2;
// NSLog (#" SENT ");
break;
SLComposeViewControllerResultCancelled box:
output = #"Your tweet has-been canceled ";
status = 3;
// NSLog (#" canceled ");
break;
default:
break;
}
[controllerSLC dismissViewControllerAnimated:YES completion:nil] ;
};
}
I only got an error :
Warning Attempt to present <SLComposeViewController > on <CFenPrincipaleViewController> Whose view is not in the window hierarchy !
I added the code :
UIViewController *activeController = [UIApplication sharedApplication] keyWindow.rootViewController. ;
if ([ activeController isKindOfClass:[UINavigationController class]]) {
activeController = [(UINavigationController *)activeController visibleViewController] ;
}
[activeController presentViewController:controllerSLC animated:YES completion:Nil];
It works on the window home application, I have no error .
But when I call the same function on another window , the error returns ....
Thank you in advance for your help

Answer 1

I had the same issue...give this a shot!
First get the root view controller....
-(UIViewController*) getRootViewController {
return [UIApplication sharedApplication].keyWindow.rootViewController;
}
Now instead of activeController = [(UINavigationController *)activeController visibleViewController] ;
Do this:
UIViewController* activeController = [self getRootViewController];
Now your last line [activeController presentViewController:controllerSLC animated:YES completion:Nil]; should work.
Hope this helps.
