This App getting crashed when I tapped tabbar-4 in iOS 11 only. I don't understand what's the wrong with my code. I didn't get any code related to refreshController either on Hometabviewcontroller or accountscontroller. but I got the following when I search entire code base.
- (void)refresh:(UIRefreshControl *)refreshControl
{
[refreshControl endRefreshing];
}
Following is the viewloads code of the particular tabview controller.
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil

self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
if (self) {
// Custom initialization
}

self.navigationController.navigationBar.titleTextAttributes = @{NSForegroundColorAttributeName: UIColorFromRGB(0XfEAA26)};
}

[[ProgressIndicator sharedInstance] showPIOnWindow:window withMessge:NSLocalizedString(@"Loading...",@"Loading...")];
_pastCycle = [[NSMutableArray alloc]init];

}
}];

回答1:
You can track where the unrecognized selector sent to instance comes from. Something in your code is calling it.
Do a text search in hometabviewcontroller or entire project for refreshControl and see where and what is calling it and make sure it's what you want.
If that does not help we need more code (preferably hometabviewcontroller) to help you.
