在导航栏左侧添加标题

Question

是否可以在导航栏左侧添加标题？我知道如何在中间添加标题，但是当我尝试在左侧添加标题时，我什么也看不到。这是我的代码：

self.navigationItem.leftBarButtonItem?.title = "Elapsed Time: 0:00"

感谢您的帮助。

Answer 1

试试这个代码：

let leftItem = UIBarButtonItem(title: "Title",
                                   style: UIBarButtonItemStyle.plain,
                                   target: nil,
                                   action: nil)
    leftItem.isEnabled = false
    self.navigationItem.leftBarButtonItem = leftItem

这个问题更强大的解决方案：

let longTitleLabel = UILabel()
    longTitleLabel.text = "Long long long long long long title"
    longTitleLabel.font = ................
    longTitleLabel.sizeToFit()

    let leftItem = UIBarButtonItem(customView: longTitleLabel)
    self.navigationItem.leftBarButtonItem = leftItem

现在您可以随意编辑标签了。您可以使用其他字体或文本颜色。

Answer 2

您可以尝试创建一个自定义视图，然后创建一个包含该自定义视图的 UIBarButtonItem。

自定义视图：

var button = UIButton(frame: CGRectMake(0, 0, 44, 44))
var label = UILabel(frame: CGRectMake(0, 0, 44, 14)) // adjust as you see fit

label.text = "Label test"
label.textAlignment = NSTextAlignment.Left

button.addSubview(label)

// Add it to your left bar button

self.navigationItem.leftBarButtonItems = [barButtonNegativeSpacer, UIBarButtonItem(customView: button)

Answer 3

    navigationController?.navigationBar.isTranslucent = false
    
    let titleLabel = UILabel(frame: CGRect(x: 0, y: 0, width: view.frame.width - 32, height: view.frame.height))
    titleLabel.text = "  Home"
    titleLabel.textColor = UIColor.white
    titleLabel.font = UIFont.systemFont(ofSize: 20)
    navigationItem.titleView = titleLabel
