Assume the following code snippet: UIFont* systemFont = [UIFont systemFontOfSize:20.0];
NSDictionary<NSAttributedStringKey,id>* attributes = [NSDictionary dictionaryWithObject:systemFont forKey:NSFontAttributeName];
[@"" drawAtPoint:CGPointMake(100.0,100.0) withAttributes:attributes];When checking the system font if the glyph (smiley) does exist the result is NO. But the glyph is correctly drawn. Why? 😕The smiley exists only in font "Apple Color Emoji".

In iOS 11.0+ I use the following statements to add a UISearchController to the navigation bar:[[self navigationItem] setSearchController:[self myUISearchController]];
[[self navigationItem] setHidesSearchBarWhenScrolling:NO];
[self setDefinesPresentationContext:YES];To hide the UISearchController I tried the following:[[self myUISearchController] setActive:NO];
[[self myUISearchController] removeFromParentViewController]; // just a try
[[self navigationItem] setSearchController:nil]; // this should be sufficient
[self myUISearchController:nil];Actually, the search controller disappears but leaves a black rectangle at the position where it was. It seems to be that the UITableViewController inside the UINavigationController does not re-align its table view and therefore leaves a black rectangle.Any ideas?
