Use UIBarButtonItem icon in UIButton

New iOS 13 support SF Symbols now
UIImage(systemName: "trash")

for swift 4.2 (call it on main thread)

extension UIBarButtonItem.SystemItem {    func image() -> UIImage? {        let tempItem = UIBarButtonItem(barButtonSystemItem: self,                                       target: nil,                                       action: nil)        // add to toolbar and render it        let bar = UIToolbar()        bar.setItems([tempItem],                     animated: false)        bar.snapshotView(afterScreenUpdates: true)        // got image from real uibutton        let itemView = tempItem.value(forKey: "view") as! UIView        for view in itemView.subviews {            if let button = view as? UIButton,                let image = button.imageView?.image {                return image.withRenderingMode(.alwaysTemplate)            }        }        return nil    }}

UIBarButtonSystemItem.play.image()

For Objective-C:

+ (UIImage *)imageFromSystemBarButton:(UIBarButtonSystemItem)systemItem {    UIBarButtonItem* tempItem = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:systemItem target:nil action:nil];    // Add to toolbar and render it    UIToolbar *bar = [[UIToolbar alloc] init];    [bar setItems:@[tempItem] animated:NO];    [bar snapshotViewAfterScreenUpdates:YES];    // Get image from real UIButton    UIView *itemView = [(id)tempItem view];    for (UIView* view in itemView.subviews) {        if ([view isKindOfClass:[UIButton class]]) {            return [(UIButton*)view imageForState:UIControlStateNormal];        }    }    return nil;}

Here's a solution that works with ANY System bar button item + it supports tintColor:

- (void)viewDidLoad {    [super viewDidLoad];    [self.button setImage:[self imageFromSystemBarButton:UIBarButtonSystemItemTrash]                 forState:UIControlStateNormal];    self.button.tintColor = [UIColor redColor];}- (UIImage *)imageFromSystemBarButton:(UIBarButtonSystemItem)systemItem {    // Holding onto the oldItem (if any) to set it back later    // could use left or right, doesn't matter    UIBarButtonItem *oldItem = self.navigationItem.rightBarButtonItem;    UIBarButtonItem *tempItem = [[UIBarButtonItem alloc]                                 initWithBarButtonSystemItem:systemItem                                 target:nil                                 action:nil];    // Setting as our right bar button item so we can traverse its subviews    self.navigationItem.rightBarButtonItem = tempItem;    // Don't know whether this is considered as PRIVATE API or not    UIView *itemView = (UIView *)[self.navigationItem.rightBarButtonItem performSelector:@selector(view)];    UIImage *image = nil;    // Traversing the subviews to find the ImageView and getting its image    for (UIView *subView in itemView.subviews) {        if ([subView isKindOfClass:[UIImageView class]]) {            image = ((UIImageView *)subView).image;            break;        }    }    // Setting our oldItem back since we have the image now    self.navigationItem.rightBarButtonItem = oldItem;    return image;}

P.S. Feel free to improve if you know of a better way, thanks.

Download the image from somewhere on the web, add it to your project and set the UIButton's image to the image you just downloaded.

I did not find the same as Apple is using but I found this one. Simply change it's color in Pixelmator or Photoshop.
