title: Missing context for method declaration?
body: <p>I am trying to create an app and when I added this IBAction, it gave me the error Missing context for method declaration. I have looked up how to fix this but I am a bit confused since I am a beginner. The errors appear in my .m file:</p>
  
  <pre><code>#import "QRscannerSecondViewController.h"
  
  @end
  
  @interface QRscannerSecondViewController ()
  
  @end
  
  @implementation QRscannerSecondViewController
  
  - (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
  {
  self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
  if (self) {
      self.title = NSLocalizedString(@"Info", @"Info");
      self.tabBarItem.image = [UIImage imageNamed:@"second"];
  }
  return self;
  }
  
  
  - (void)viewDidLoad
  {
  [super viewDidLoad];
  // Do any additional setup after loading the view, typically from a nib.
  }
  
  - (void)didReceiveMemoryWarning
  {
  [super didReceiveMemoryWarning];
  // Dispose of any resources that can be recreated.
  }
  
  @end
  
  -(IBAction)button1
  {
  [input resignFirstResponder];
  l11 = input.text;
  line11.text = [[NSString alloc] initWithFormat:@"%2.f", l11];
  }
  </code></pre>
  
  <p>but I though that it would help if I included my .h file, also.</p>
  
  <pre><code>#import &lt;UIKit/UIKit.h&gt;
  
  @interface QRscannerSecondViewController : UIViewController
  
  @end
  
  @interface TextGameViewController : UIViewController
  {
  IBOutlet UITextField *input;
  IBOutlet UILabel *line11;
  NSString *l11;
  }
  -(IBAction)button1;
  </code></pre>
