Can't connect IBAction to view - ios

Question

I'm new to iOS and I'm following this tutorial.
Here is a screenshot of me trying to connect an IBAction to my view.
I want to execute the method releaseKeyboard whenever I touch the view (ie. close the keyboard).
I'm not using storyboard.
My files:
challAppDelegate.h
challAppDelegate.m
challViewController.h
challViewController.m
challViewController.xib
challAppDelegate.h
#import <UIKit/UIKit.h>
#interface challAppDelegate : UIResponder <UIApplicationDelegate>
{
UINavigationController *navigationController;
}
#property (strong, nonatomic) UIWindow *window;
#property (strong, nonatomic) UINavigationController *navigationController;
#end
challAppDelegate.m
#import "challAppDelegate.h"
#import "challViewController.h"
#implementation challAppDelegate
#synthesize window = _window;
#synthesize navigationController;
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
UIViewController *rootController =
[[challViewController alloc]
initWithNibName:#"challViewController" bundle:nil];
navigationController = [[UINavigationController alloc]
initWithRootViewController:rootController];
self.window = [[UIWindow alloc]
initWithFrame:[[UIScreen mainScreen] bounds]];
[self.window addSubview:navigationController.view];
[self.window makeKeyAndVisible];
return YES;
}
...
...
challViewController.h
#import <UIKit/UIKit.h>
#interface challViewController : UIViewController
#property(nonatomic, retain) IBOutlet UITextField *signInEmailAddress;
#property(nonatomic, retain) IBOutlet UITextField *signInPassword;
#property(nonatomic, retain) IBOutlet UIButton *signInSignInButton;
#property(nonatomic, retain) IBOutlet UIButton *signInRegisterButton;
-(void) releaseKeyboardAction;
-(IBAction) signInAction:(int)sender;
-(IBAction) registerAction:(int)sender;
-(IBAction) releaseKeyboard:(id)sender;
#end
challViewController.m
#import "challViewController.h"
#interface challViewController ()
#end
#implementation challViewController
#synthesize signInEmailAddress; // cria os getters e setters
#synthesize signInPassword; // cria os getters e setters
#synthesize signInSignInButton; // cria os getters e setters
#synthesize signInRegisterButton; // cria os getters e setters
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
if (self) {
// Custom initialization
}
return self;
}
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view from its nib.
self.title = #"Sign In";
}
- (void)didReceiveMemoryWarning
{
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}
- (void)releaseKeyboardAction
{
[signInEmailAddress resignFirstResponder];
[signInPassword resignFirstResponder];
}
- (IBAction)releaseKeyboard:(id)sender
{
[self releaseKeyboardAction];
}
- (IBAction)registerAction:(int)sender
{
//
}
- (IBAction)signInAction:(int)sender
{
//
}
#end
What am I doing wrong?
Thanks

Answer 1

You can add a UITapGestureRecognizer to self.view.
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view from its nib.
self.title = #"Sign In";
UITapGestureRecognizer *gesture = [[UITapGestureRecognizer alloc] initWithTarget:self action:#selector(releaseKeyboardAction)];
[self.view addGestureRecognizer:gesture];
}
The target of the gesture recogniser points to your releaseKeyboardAction method.

Just change the view's class from UIView to UIControl in the identity inspector and then you can connect IBActions.
