Question

I’m using an Objective-C class (UIView). In that class I’m calling an NSURLConnection (added NSURLConnectionDelegate to .h) When I start the connection, nothing happens. It’s not calling its methods. Is it just not possible to call NSURLConnection in a UIView class or am I doing something wrong?

Thanks.

Answer 1

First of all, it’s not enough to add <NSURLConnectionDelegate> to your object’s interface declaration, you should explicitly set it as the NSURLConnection‘s delegate.

Secondly, UIView is definitely a wrong candidate as an NSURLConnection delegate, because:

• UIView is the view part of MVC;
• the view may be unloaded unless you take extra measures like retaining it in the UIViewController.

That makes UIViewController a better choice as an NSURLConnection delegate.
