I would like to add an UIActivityIndicatorView (_av object) object into a left bar button item of UINavigationItem
My code looks like :
UIBarButtonItem * button = [[UIBarButtonItem alloc] initWithCustomView:_av];
[self.navigationItem setLeftBarButtonItem:button];
[button release];
but after I launch the code I take an error:
*** Assertion failure in -[UINavigationBar layoutSublayersOfLayer:], /SourceCache/UIKit/UIKit-2380.17/UIView.m:5776
2013-04-15 16:28:39.246 * [12484:907] * Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'Auto Layout still required after executing -layoutSubviews. UINavigationBar's implementation of -layoutSubviews needs to call super.'
How I should to implement it correctly ?
