Can't hide iOS Keyboard (xcode 5) in current project - ios

Question

Xcode 5 / iOS 7.
This problem has been driving me crazy for the better part of a day now. In my current project, I'm unable to hide the iOS keyboard using resignFirstResponder. However, strangely, I am able to get this to work in all other projects I'm currently working on. Code below. Thanks so much, guys!
ViewController.h:
#import <UIKit/UIKit.h>
#interface ViewController : UIViewController <UITextFieldDelegate>
{
IBOutlet UISegmentedControl *selectcontrolNumbers;
IBOutlet UILabel *output;
int grossNetVar;
double calcVariable;
IBOutlet UIButton *hideConvertNet;
IBOutlet UIButton *hideConvertGross;
}
#property (strong, nonatomic) IBOutlet UITextField *dollarTextField;
#property (nonatomic)int grossNetVar;
#property (nonatomic) double calcVariable;
- (IBAction)selectAction:(id)sender;
- (IBAction)convertToNet:(id)sender;
- (IBAction)convertToGross:(id)sender;
#end
ViewController.m:
#import "ViewController.h"
#interface ViewController ()
#end
#implementation ViewController
#synthesize grossNetVar;
#synthesize calcVariable;
- (void)viewDidLoad
{
[super viewDidLoad];
self.dollarTextField.delegate = self;
}
-(void) touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {
[self.dollarTextField resignFirstResponder];
}
- (void)didReceiveMemoryWarning
{
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}
- (IBAction)selectAction:(id)sender {
if (selectcontrolNumbers.selectedSegmentIndex == 0){
grossNetVar = 1;
} else {
grossNetVar = 2;
}
if (grossNetVar == 1) {
hideConvertGross.enabled = YES;
hideConvertNet.enabled = NO;
} else {
hideConvertGross.enabled = NO;
hideConvertNet.enabled = YES;
}
}
- (IBAction)convertToNet:(id)sender {
NSString *textFieldText = _dollarTextField.text;
calcVariable = .85;
double dollarTotal = [textFieldText doubleValue];
double netCalc = calcVariable * dollarTotal;
NSString *netString = [[NSString alloc]initWithFormat:#"The NET total is %g", netCalc];
output.text = netString;
}
- (IBAction)convertToGross:(id)sender {
}
#end

I would recommend using a toolbar (you can drag one on to the screen into the storyboard) that only appears when the keyboard is opened, and put a done button on that. Create an IBAction for the touchdown of that button in which you can do
[donebutton resignFirstResponder];
