将 UIView 插入 UIToolbar

Question

我想将 UIView 插入 UIToolbar。（见图）我已经尝试过 .addSubview 但它不起作用。感谢您提供的任何帮助！

 // Toolbar -> Done Butotn
    let toolbar = UIToolbar()
    toolbar.sizeToFit()

    let flexibleSpace = UIBarButtonItem(barButtonSystemItem: UIBarButtonSystemItem.flexibleSpace, target: nil, action: nil)
    let doneButton = UIBarButtonItem(barButtonSystemItem: UIBarButtonSystemItem.done, target: self, action:#selector(doneButtonClicked))

    toolbar.setItems([flexibleSpace, doneButton], animated: false)

    self.TextInput.inputAccessoryView = toolbar

Answer 1

将视图添加为从您的自定义视图创建的 UIBarButtonItem：

let someCustomView = ... // your custom view
let customItem = UIBarButtonItem(customView: someCustomView)
let flexibleSpace = UIBarButtonItem(barButtonSystemItem: UIBarButtonSystemItem.flexibleSpace, target: nil, action: nil)
let doneButton = UIBarButtonItem(barButtonSystemItem: UIBarButtonSystemItem.done, target: self, action:#selector(doneButtonClicked))

toolbar.setItems([customItem, flexibleSpace, doneButton], animated: false)

你应该在设置项目后调用 toolbar.sizeToFit()。
