UIScrollView not responding to touch - ios

Question

My UIScrollView is not responding to touch events, nor is my touchesBegain method being called for my UIViewController. (Also the text on my buttons are distorted on one and not shown on the other)
In Storyboard I added the ScrollView to the UIViewController and added my UITextFields and UIButtons to the ScrollView
Here is the code:
#import <UIKit/UIKit.h>
#interface RefineSearchViewController : UIViewController <UITextFieldDelegate, UIScrollViewDelegate>
{
IBOutlet UIScrollView *scroller;
}
#property (strong, nonatomic) IBOutlet UITextField *nameField;
#property (strong, nonatomic) IBOutlet UITextField *targetField;
#property (strong, nonatomic) IBOutlet UITextField *vendorField;
#property (strong, nonatomic) IBOutlet UITextField *CATField;
#property (strong, nonatomic) IBOutlet UITextField *clonalityField;
#property (strong, nonatomic) IBOutlet UITextField *sourceOrganismField;
-(IBAction) textFieldReturn: (id) sender;
#import "RefineSearchViewController.h"
#import "DBHandler.h"
#interface RefineSearchViewController ()
#end
#implementation RefineSearchViewController
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
if (self) {
// Custom initialization
}
return self;
}
- (void)viewDidLoad
{
[scroller setScrollEnabled:YES];
// set the content size to be the size our our whole frame
//scroller.frame = CGRectMake(74, 261, 620, 354);
[scroller setContentSize:CGSizeMake(2000, 2000)];
[scroller setCanCancelContentTouches:NO];
[super viewDidLoad];
// Do any additional setup after loading the view.
self.targetField.delegate = self;
self.nameField.delegate = self;
self.vendorField.delegate = self;
self.clonalityField.delegate = self;
self.sourceOrganismField.delegate = self;
self.CATField.delegate = self;
}
-(void) viewWillAppear:(BOOL)animated
{
self.navigationController.navigationBarHidden = YES;

// If you are going to conduct a refine search
if ([[segue identifier] isEqualToString:#"Refine"])
{
DBHandler *handler = [[DBHandler alloc]init];
//Run searches on each of the parameter that aren't empty
NSString *nameParameter = _nameField.text;
if (![nameParameter isEqualToString:#""])
{
[handler search:0 andInput:nameParameter];
}
NSString *targetParameter = _targetField.text;

{
[handler search:5 andInput:sourceField];
}
//recursive implementation
for (int i = 0; i < 6 ; i++)
{
}
//We shouldn't clear the text fields here in my personal opinion because they apply to the search until you return to the homescreen and reset what is the
//current "working database"
}
//if you are going to cancel the refine search, simply go back to the previous screen
else if ([[segue identifier] isEqualToString:#"Cancel"])
{
//Do Nothing

//....clear Text Fields
_nameField.text = #"";

Make sure your scrollView's delegate is set properly in storyboard and scrollView's userInteractionEnabled is set.
