Sorry to post this as an answer rather than a comment but as you can see I'm new to Stack Overflow and so I'm not yet reputable enough to post comments!
Anyway I second @cire about making sure to set the first responder status once the view is part of the view hierarchy. So setting first responder status in your view controllers viewDidLoad
method won't work for example. And if you're unsure as to whether it is working [view becomeFirstResponder]
returns you a boolean that you can test.
Another point: you can use a view controller to capture the shake event if you don't want to create a UIView subclass unnecessarily. I know it's not that much hassle but still the option is there. Just move the code snippets that Kendall put into the UIView subclass into your controller and send the becomeFirstResponder
and resignFirstResponder
messages to self
instead of the UIView subclass.
