Output label in UIViewController - iphone

Question

I can link labels to ViewController.h in my main view. However, in the settings screen, the program won't let me output the label to the ViewController.h. Because of this, "testLabel" below, is marked as an undeclared identifier. I want the label to reflect whether the user is connected to the internet or not.
ViewController.h
#import <UIKit/UIKit.h>
#import <AVFoundation/AVFoundation.h>
#import "Reachability.h"
#interface ViewController : UIViewController <UIImagePickerControllerDelegate, UINavigationControllerDelegate> {
Reachability *internetReachableFoo;
}
- (IBAction)cameraButtonClicked:(id)sender;
#property (strong, nonatomic) IBOutlet UIImageView *imageView;
#property (weak, nonatomic) IBOutlet UILabel *testLabel; //Not linked
#end
ViewController.m
- (void)testInternetConnection
{
internetReachableFoo = [Reachability reachabilityWithHostname:#"www.google.com"];
// Internet is reachable
internetReachableFoo.reachableBlock = ^(Reachability*reach)
{
// Update the UI on the main thread
dispatch_async(dispatch_get_main_queue(), ^{
testLabel.text = #"YAY Intrawebs!!";
});
};
// Internet is not reachable
internetReachableFoo.unreachableBlock = ^(Reachability*reach)
{
// Update the UI on the main thread
dispatch_async(dispatch_get_main_queue(), ^{
testLabel.text = #"Someone broke the internet";
});
};
[internetReachableFoo startNotifier];
}

Answer 1

Have you connected the label in the storyboard?
Once that is done...you will have to reference the testLabel by
_testLabel
or
self.testLabel
May will have to make a weak reference to the label because if it is in a block. Like this:
// Update the UI on the main thread
__block __weak ViewController *weakself = self;
dispatch_async(dispatch_get_main_queue(), ^{
weakself.testLabel.text = #"YAY Intrawebs!!";
});
