see if the IBAction of the buttons are connected properly. I guess they are not properly connected
It would be much helpful if you post your source code rather than error out come.
Anyway i think you are trying to call an instance method through class reference.
The problem is here:
[Protoype_Test1ViewController saveImage]
It should be:
[protoype_Test1ViewController saveImage]
This is a common mistake when relay much on auto complete.

App crashes when I pop a view from NavigationController using a UIButton

I'm pushing a simple view onto a NavigationController. The view loads fine, and when I use the built-in back button, it is properly popped.
However, when I try and pop the view with my own UIButton within the view, I get a crash.
This is the action run by my UIButton:
-(IBAction)iAgreePressed {
[[self navigationController] popViewControllerAnimated:YES];}
Am I missing something obvious here?
This is the error coming back in the console:

Thank you for your time!
Method signatures don't match. The button is sending
-[LegalAgreementController iAgreePressed:]
but you defined
-[LegalAgreementController iAgreePressed] //(note one arg versus no arg)
IBActions should be defined as:
- (IBAction) someMethod:(id)sender
You don't strictly have to include that arg, but you want to for consistency.
