如何在 UIView 中单击 UIButton 时打开 UIViewController

Question

I wants to open a UIViewController on Click of UIButton which is inside a UIView . The UIView has it's own .h & .m file & The action property of button is declared inside the it.

the navigation code is working fine if I am calling it from UIViewController of UIbutton which is like

UIStoryboard *mainStoryboard = [UIStoryboard storyboardWithName:@"Main" bundle: nil];
FilterDemoTableViewController *viewController = (FilterDemoTableViewController*)     [mainStoryboard instantiateViewControllerWithIdentifier:  @"FilterDemoTableViewController_Id"];
[[self navigationController]pushViewController:viewController animated:YES];

but if same code is calling from UIView .m file then it's not working plz help me.

And it won't. You can't call [self navigationController] inside UIView because it doesn't have one.

All you have to do is to reference the ViewController that owns your UIView and call a method there.

Typically, you can do it with NSNotification - not the best way but definitely works.
