Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[UIViewControllerWrapperView buttonPressed]: - uibutton

Question

I've been trying to search for solution, but answers to similar problems didn't quite point me in right direction. The problem is as follows
in my iOS app i create a custom image view atop of my navigation controller. this is done via alloc initing BannerView Class from designated view controllers
e.g. in viewDidLoad of my MasterViewController i call
BannerView *bannerLogoView = [[BannerView alloc]init];
//add the tabcotroller as a subview of the view
[self.tabBarController.view addSubview:bannerLogoView.bannerView];
BannerView.m
#import "BannerView.h"
#interface BannerView ()
#end
#implementation BannerView
-(id)init {
self = [super init];
if (self) {
self.imageView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:#"bannerImage.jpg"]];
self.bannerView = [[UIView alloc] initWithFrame:CGRectMake(0,20, 320, 30)];
[self.bannerView addSubview:self.imageView];
//NSLog(#"Setting up image from within banner view");
[self setupButton];
}
return self;
}
- (void)buttonPressed {
NSLog(#"Button pressed");
}
-(void) setupButton {
self.imageView.userInteractionEnabled = YES;
self.button= [UIButton buttonWithType:UIButtonTypeRoundedRect];
[self.button addTarget:self action:#selector(buttonPressed) forControlEvents:UIControlEventTouchUpInside];
self.button.frame = CGRectMake(0.0, 0.0, 320.0, 30.0);
[self.imageView addSubview:self.button];
}
Now anytime the button is clicked i get either EXC_BAD_ACCESS with no console output, or
Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[UIViewControllerWrapperView buttonPressed]: unrecognized selector sent to instance
Could anyone help me out? I might be doing something wrong with topology/inheritance here, but I can't find a simple way to find this out..
Thank you in advance

Not sure what's causing your problem but you do have some weird constructs here.
First, usually buttons are not added to UIImageViews. Instead, add them both to a common view and then call the common view's -bringSubviewToFront: to overlay the button onto the image view.
Second, the selector takes the sender as an argument, so your selection should be buttonPressed: and method should be -(void)buttonPressed:(id)sender;
