Answer 1

if you are at any other thread, then it will not work cz UI not work in inner thread. use this

-(void)refreshView:(NSNotification*)notification
{


dispatch_async(dispatch_get_main_queue(), ^{
 activity.hidden = YES;
    self.view.userInteractionEnabled =YES;

        });    
    NSLog(@"alles geladen zeiger wird geladen");



}
