Add the Activity indicator as a subview of the button:

// Create spinner
UIActivityIndicatorView *myIndicator = [[UIActivityIndicatorView alloc] 
  initWithActivityIndicatorStyle:UIActivityIndicatorViewStyleWhite];

// Position the spinner
[myIndicator setCenter:CGPointMake(50.0, 30.0)];

// Add to button
[myButton addSubview:myIndicator];

// Start the animation
[myIndicator startAnimating];
