How to navigate from UIView to UIViewController - objective-c

Question

i am aware that uiview does not have navigational control. Thus, i am not able to push from the uiview to the next uiviewcontroller.
here is the code of my method. Please help. Thanks!
- (void)scrollViewDoubleTapped:(UITapGestureRecognizer*)recognizer {
CGPoint pointInView = [recognizer locationInView:self];
NSLog(#"%f , %f",pointInView.x,pointInView.y);
if ((pointInView.x >= (231.0) && pointInView.x <=(293) && pointInView.y >= (193) && pointInView.y <=(218)) )
{
// how to push to next viewcontroller here?
UIView *view = [UIGestureRecognizer view]; //what should i do for this code?
[self viewController];
}
}
-(TestViewViewController*)viewController
{
for (UIView *next = [self superview]; next; next = next.superview)
{
UIResponder *nextResponder = [next nextResponder];
if([nextResponder isKindOfClass:[TestViewViewController class]])
{
return (TestViewViewController*)nextResponder;
}
}
return nil;
}

If you want to get viewcontroller having a view than you can use nextResponder method
So first you get the view from gestureRecognizer:
UIView *view = [gestureRecognizer view];
and than search for the viewcontroller containing the view
Look here
Edit:
if ((pointInView.x >= (231.0) && pointInView.x <=(293) && pointInView.y >= (193) && pointInView.y <=(218)) )
{
// how to push to next viewcontroller here?
UIView *view = [recognizer view]; //what should i do for this code?
UIViewController *viewController = [self getViewControllerFromView:view];
if(viewController) {
// do whatever you want...
UIViewController *newViewController = ...
[viewController.navigationController pushViewController:newViewController animated:YES];
}
}
...
I rewrote method get ViewController to your case. To get it from some view:
-(UIViewController*)getViewControllerFromView:(UIView*) view
{
if([[view nextResponder] isKindOfClass:[UIViewController class]])
{
return (UIViewController*)[view nextResponder];
}
else {
for (UIView *next = [view superview]; next; next = next.superview)
{
UIResponder *nextResponder = [next nextResponder];
if([nextResponder isKindOfClass:[UIViewController class]])
{
return (UIViewController*)nextResponder;
}
}
}
return nil;
}
new edit::
your EAGLView has #property (nonatomic, retain) UIViewController *viewController;
ADD #synthesize viewController = _viewController; to .m file.
CoreMotionAppDelegate::
MainViewController * itemsViewController = [[MainViewController alloc]init];
UINavigationController *navController = [[UINavigationController alloc] initWithRootViewController:itemsViewController];
glView.viewController = itemsViewController;
[glView startAnimation];
[[self window]setRootViewController:navController];
And than in your scrollViewDoubleTapped method just
EAGLView *v = (EAGLView*)[recognizer view];
UIViewController *viewController = v.viewController;
