Question

I’m trying to use NSURLConnection to “talk” to a server but when trying to use initWitRequest I get this error:

no known class method for selector 'initWithRequest:delegate:'

Is this not a proper usage of the method?

NSURLConnection *conn = [NSURLConnection initWithRequest:theRequest delegate:self];

My Deployment Target is iOS 4.3. Under Base SDK it has listed Latest iOS (iOS 5.0). Could this be an issue?

You’re attempting to send -initWithRequest:delegate: to the NSURLConnection class instead of an instance of that class.

By convention, any -init method should be preceded by a message to alloc on the class. In your example, conn would be created like so:

NSURLConnection *conn = [[NSURLConnection alloc] initWithRequest:request delegate:self];
