Error message Use of undeclared identifier - ios

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;

Answer 2

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
