Calling (void)load from viewController

Question

I am trying to load web data asynchronously. I understand that I can use the following, but I don't know how to call the void(load) method. How do I call this? It doesn't appear to be called automatically. Thanks!

- (void)load
{
NSURL *myURL = [NSURL URLWithString:[NSString 
stringWithFormat:@"http://www.website.com"]];

NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:myURL 
cachePolicy:NSURLRequestReloadIgnoringLocalCacheData timeoutInterval:60];

[[NSURLConnection alloc] initWithRequest:request delegate:self];
}

1. Maybe `[self load];`? 2. Why do you expect this to be called automatically? — , Feb 23 '13 at 10:56
I think you're thinking of the _class_ method `load`, which isn't a suitable place for this sort of functionality. — jrturton, Feb 23 '13 at 12:16

Like H2CO3 said, you should call the method by using [self load]. I would expect you want to call it in the method -(void)viewDidLoad. This is called once for when the view is loaded.

__attribute__((constructor)) 
- (void)load
{
NSURL *myURL = [NSURL URLWithString:[NSString 
stringWithFormat:@"http://www.website.com"]];

NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:myURL 
cachePolicy:NSURLRequestReloadIgnoringLocalCacheData timeoutInterval:60];

[[NSURLConnection alloc] initWithRequest:request delegate:self];
}

It's run when a shared library is loaded, typically during program startup.

Take a look at How exactly does __attribute__((constructor)) work?
