Question

When I call my urlconnection method from my (IBAction)buttonpressed method like this:

[self connectWeb];

I get error “request for member connectWeb in something not a structure or union”

but when I call the same method from my – (void)viewDidLoad method it works!?

Answer 1

Where is the connectWeb method in your implementation file?

I would guess that it is before viewDidLoad but after buttonPressed.

The reason for this is that the connectWeb method has been declared before viewDidLoad, so viewDidLoad is aware of it, whereas it’s after the buttonPressed method, so the buttonPressed method isn’t aware of it.

You have a couple of options.

1. Declare the method before any other method uses it.

- (void)connectWeb;

Then you can implement it anywhere within the implementation.

1. Move the implementation of connectWeb to before both viewDidLoad and buttonPressed – both the methods will then be aware of connectWeb.
