Childview
@interface GenWarnDangerVC : UIViewController <UITextViewDelegate>
@property (weak, nonatomic) IBOutlet UITextView *riddorText;
In the parent I want to access the UITextView but can't quite getv the syntax
NSString* tempString = self.currentChildController.view.riddorText;
NSString* tempString = self.currentChildController.riddorText;
NSString* tempString = self.childViewControllers[0].riddorText;
etc
Set up goes like this
[self addChildViewController:[self.storyboard instantiateViewControllerWithIdentifier:@"ChildFour"]];
GenWarnDangerVC * GenWarnDanger_vc = [self.storyboard instantiateViewControllerWithIdentifier:@"ChildOne"];
[self addChildViewController:GenWarnDanger_vc];
GenWarnDanger_vc.delegate = self;
self.currentChildController = self.childViewControllers[0];
self.currentChildController.view.frame = self.containerView.bounds;
[self.containerView addSubview:self.currentChildController.view];
If take into account possible extensibility and/or reusability, here is the safe way to access up-casted specific child controller
if ([self.currentChildController isKindOfClass:GenWarnDangerVC.class])
{
GenWarnDangerVC *controller = (GenWarnDangerVC *)self.currentChildController;
// << do anything with "controller" directly access properties & methods
// for example
controller.riddorText.text = @"New text";
}
