Displaying signature capture image - ios

Question

I have an app that asks the user for information then their signature. Upon clicking the "sign" button they are taken to a view controller called "myviewcontroller".
From there what I want to show is the following screen, however whenever I click the "sign" button the signature capture takes the entire screen, and while it works I am unable to see the "x" where they should sign.
I don't know what I am missing, or what I've incorrectly called that's causing this to happen.
#import "MyViewController.h"
#interface MyViewController ()
#end
#implementation MyViewController
#synthesize mySignatureImage;
#synthesize lastContactPoint1, lastContactPoint2, currentPoint;
#synthesize imageFrame;
#synthesize fingerMoved;
#synthesize navbarHeight;
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
if (self) {
// Custom initialization
}
return self;
}
- (void)viewDidLoad
{
[super viewDidLoad];
//set the title of the navigation view
[self.navigationItem setTitle:#"Sign here"];
//create a save button in the navigation bar
UIBarButtonItem *myButton = [[UIBarButtonItem alloc]
initWithTitle:#"Save"
style:UIBarButtonItemStylePlain
target:self
action:#selector(saveSignature:)];
[self.navigationItem setRightBarButtonItem:myButton];
//set the view background to light gray
self.view.backgroundColor = [UIColor lightGrayColor];
//get reference to the navigation frame to calculate navigation bar height
CGRect navigationframe = [[self.navigationController navigationBar] frame];
navbarHeight = navigationframe.size.height;
//create a frame for our signature capture based on whats remaining
imageFrame = CGRectMake(self.view.frame.origin.x+10,
self.view.frame.origin.y-5,
self.view.frame.size.width-20,
self.view.frame.size.height-navbarHeight-30);
//allocate an image view and add to the main view
mySignatureImage = [[UIImageView alloc] initWithImage:nil];
mySignatureImage.frame = imageFrame;
mySignatureImage.backgroundColor = [UIColor whiteColor];
[self.view addSubview:mySignatureImage];
}
There's more code for the actual signature capture, but this is the stuff directly related to the view controller.
