在UIBarButtonItem上的ios-fontawesome

Question

我正在尝试使用iOS FontAwesome在条形按钮上设置图标，如下所示：

[self.barButton setTitle:[NSString fontAwesomeIconStringForEnum:FACamera]];

还有这个：

[self.barButton setTitle:[NSString fontAwesomeIconStringForIconIdentifier:@"fa-camera"]];

无论我使用什么标识符，结果都是相同的：

可能出现什么问题？

Answer 1

万一其他人想知道：

[self.barButton setTitleTextAttributes:@{
                  NSFontAttributeName: [UIFont fontWithName:@"FontAwesome" size:24.0],
                  NSForegroundColorAttributeName: self.view.tintColor
                                         } forState:UIControlStateNormal]; 
[self.barButton setTitle:[NSString fontAwesomeIconStringForIconIdentifier:@"fa-camera"]];

在斯威夫特：

    let filterButton = UIBarButtonItem(title: String.fontAwesomeIconWithName(FontAwesome.Filter), style: UIBarButtonItemStyle.Plain, target: self, action: Selector("filterClicked"))
    filterButton.setTitleTextAttributes(NSDictionary(dictionary: [NSFontAttributeName:UIFont.fontAwesomeOfSize(25), NSForegroundColorAttributeName : UIColor.COLOR_BLUE_DARK]), forState: UIControlState.Normal)

    self.navigationItem.rightBarButtonItem = filterButton

Answer 3

使用FontAwesomeKit 2.2 API，您可以这样做：

[self.barButton setTitleTextAttributes:@{
    NSFontAttributeName: [FAKFontAwesome iconFontWithSize:20]
} forState:UIControlStateNormal];
[self.barButton setTitle:[FAKFontAwesome cameraIconWithSize:20].attributedString.string];

或转换为UIImage，如FontAwesomeKit documentation中建议的那样：

FAKFontAwesome *cameraIcon = [FAKFontAwesome cameraIconWithSize:20];
UIImage *cameraImage = [cogIcon imageWithSize:CGSizeMake(20, 20)];
[self.barButton setImage:camera];

在 Swift 4 中，这对我有用

let button1 = UIBarButtonItem(title: "\u{f05a}", style: .plain, target: self, action: #selector(showCartInfoPopUp(_:)))
           
button1.setTitleTextAttributes([.font : UIFont(name: "Font Awesome 5 Pro", size: 24), .foregroundColor : UIColor.white], for: .normal)
            
self.navigationItem.rightBarButtonItem  = button1
