If I'm not mistaken, modal views have to be dismissed from the parent view, not from the modal view itself.
In my current project I have two modal views. In the first one, I pass data to the parent view. When the data is passed to the parent view, the dismiss is executed.
Now, I have another modal view that doesn't pass data to the parent view, so I don't know how to dismiss other than doing one self dismissModalView
Other than that, any other suggestion for a good practise on this topic?
Thanks in advance!
UPDATE:
From the answers I´m getting, I see I haven´t make myself very clear (not unusual, BTW).
I know how to self dismiss a modalViewController. That´s no problem. I also know how to use the protocol-delegate method to dismiss the modalViewController from the parent view when some data is passed.
My question is: how to dismiss the modalViewController from the parent view when no data is passed.
Thanks again!
回答1:
You can call from the modalView :
[self dismissModalViewControllerAnimated:YES];
But... If you want to have a constant coding pattern, whatever the modal view "returns" something or not, I suggest you to dismiss you views from the parent (the one that calls, the one that dismiss). But you can do both.
Does that answer your question ?
回答2:
Do take note that
[self dismissModalViewControllerAnimated:YES];
has been deprecated from iOS 6 onwards. Rather use
[self dismissViewControllerAnimated:YES completion:nil];
回答3:
You can dismiss the modal view directly (i.e. not from the parent) using
[self dismissModalViewControllerAnimated:YES];
回答4:
For IOS6 and later use
[self dismissViewControllerAnimated:YES completion:nil];
回答5:
Swift 4 and newer:
self.dismiss(animated: true, completion: nil)
回答6:
If you don't want to call it from self you can use a delegate to call it.
So you'll have a method viewControllerFinished or something that your view controller will call on it's delegate.
That way, whatever launches the modal view controller will also dismiss it. This is helpful if you need to get any information back from the view controller.

Swift version...
self.dismissViewControllerAnimated(true, completion:nil)
回答8:
You should use an unwind segue, especially since you can use it to get information from the presented view controller. This shows how to create one: http://spin.atomicobject.com/2014/10/25/ios-unwind-segues/
