Long Press: BAD_EXC_ACCESS - objective-c

Question

Here is my code:
#interface UserProfileViewController : UIViewController<UIGestureRecognizerDelegate>{
}
#property (nonatomic, retain) UILabel *myLabel;
#property (nonatomic, retain) UIImageView *imageView;
#end
#implementation UserProfileViewController
#synthesize myLabel;
#synthesize imageView;
- (void)viewDidLoad
{
[super viewDidLoad];
UIScrollView *scrollView = [[UIScrollView alloc] initWithFrame:CGRectMake(0, 0, 320, 480)];
scrollView.contentSize = CGSizeMake(320, 700);
scrollView.clipsToBounds = YES;
[scrollView setUserInteractionEnabled:YES];
myLabel = [[UILabel alloc] initWithFrame:CGRectMake(0, 0, 200, 40)];
myLabel.text = #"Kim Gysen";
myLabel.center = CGPointMake(CGRectGetWidth(self.view.bounds)/2.0f, 25);
myLabel.textAlignment = NSTextAlignmentCenter;
myLabel.textColor = [UIColor whiteColor];
[myLabel setBackgroundColor:[UIColor clearColor]];
self.imageView = [[UIImageView alloc]initWithFrame:CGRectMake(0, 0, 140, 180)];
self.imageView.center = CGPointMake(CGRectGetWidth(self.view.bounds)/2.0f, 150);
UIImage *image = [UIImage imageNamed: #"ProfilePic.jpeg"];
[imageView setImage:image];
//Long press
self.imageView.userInteractionEnabled = YES;
UILongPressGestureRecognizer *longPressGestureRecognizer = [[UILongPressGestureRecognizer alloc] initWithTarget:self action:#selector(handleLongPressFrom:)];
longPressGestureRecognizer.delegate = self;
[self.imageView addGestureRecognizer:longPressGestureRecognizer];
[scrollView addSubview:myLabel];
[scrollView addSubview:imageView];
[self.view addSubview:scrollView];
}
- (void) handleLongPressFrom: (UISwipeGestureRecognizer *)recognizer
{
CGPoint location = [recognizer locationInView:self.view];
NSLog(#"Tap Gesture Coordinates: %.2f %.2f", location.x, location.y);
if(UIGestureRecognizerStateBegan == recognizer.state)
{
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"Gesture Recognizer Demo"
message:#"Long Press Gesture performed"
delegate:nil
cancelButtonTitle:#"OK"
otherButtonTitles:nil, nil];
[alert show];
}
}
I get no errors in my ViewDidLoad, but the BAD_EXC_ACCESS error appears on the long press, before the method is actually fired. I understood that I'm leaking somewhere but where?
I'm using ARC...

You should make a property in your main view controller (typed strong) that points to the ProfileViewController then use:
self.profileView = [[UserProfileViewController alloc] init];
[self.view addSubview: self.profileView.view];
