错误消息使用未声明的标识符

Question

This is the code above:

- (void)viewDidLoad {
[super viewDidLoad];
[self showLoginProcess:false];

#ifdef DEBUG
self.usernameBox.text = @"passenger@test.com";
self.passwordBox.text = @"123456";
NSLog(@"baseUrl = %@", kBaseURL);
#endif

//TODO: check if internet is available




  (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(), ^{
                NSLog(@"There is an internet connection");
            });
        };

The first line -(void)testInternetConnection gives me an error message which says: Use of undeclared identifier 'testInternetConnection'

Thanks.

Answer 1

Check brackets , semi colons above this method.

There is problem in line above this function. select this function and Cut

(CMD + X)

then check the error in above line.

Add function in header (.h) file as - (void)testInternetConnection;

You are missing class type before the var. Try adding:

Reachability* internetReachableFoo = [Reachability reachabilityWit .... , as below

- (void)testInternetConnection
{
  Reachability* 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(), ^{
            NSLog(@"There is an internet connection");
        });
    };

Answer 3

-(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(), ^{
                NSLog(@"There is an internet connection");
            });
        };
}  // You may be missed your closing bracket
