我正在使用SwiftUI中的TextEditor来显示一个长文本的内容。

我希望这是只读的,但每当我点击它时,键盘都会弹出。

有没有一种方法可以使TextEditor成为只读的,并且当用户点击它时看不到键盘?

我尝试过.disabled(),但这不是很好,因为它阻止了控制器滚动,而且就像我说的,控制器包含一个很长的文本。

Text不好,因为它不滚动。

滚动文本的非常基本的例子:

代码语言:javascript
运行
复制
struct ContentView: View {
    @State var content = "Long text here..."

    var body: some View {
        ScrollView {
            VStack {
                Text(content)
                    .lineLimit(nil)
            }.frame(maxWidth: .infinity)
        }
    }
}

下面是一个包含一些长文本的示例:

代码语言:javascript
运行
复制
import SwiftUI

struct ContentView: View {
    @State var content =
        """
    Label

    A label can contain an arbitrary amount of text, but UILabel may shrink, wrap, or truncate the text, depending on the size of the bounding rectangle and properties you set. You can control the font, text color, alignment, highlighting, and shadowing of the text in the label.

    Button

    You can set the title, image, and other appearance properties of a button. In addition, you can specify a different appearance for each button state.

    Segmented Control
    
    The segments can represent single or multiple selection, or a list of commands.
    
    Each segment can display text or an image, but not both.
    
    Text Field
    
    Displays a rounded rectangle that can contain editable text. When a user taps a text field, a keyboard appears; when a user taps Return in the keyboard, the keyboard disappears and the text field can handle the input in an application-specific way. UITextField supports overlay views to display additional information, such as a bookmarks icon. UITextField also provides a clear text control a user taps to erase the contents of the text field.

    Slider
    
    UISlider displays a horizontal bar, called a track, that represents a range of values. The current value is shown by the position of an indicator, or thumb. A user selects a value by sliding the thumb along the track. You can customize the appearance of both the track and the thumb.
    
    Switch
    
    Displays an element that shows the user the boolean state of a given value.  By tapping the control, the state can be toggled.

    Activity Indicator View
    
    Used to indicate processing for a task with unknown completion percentage.
    
    Progress View
    
    Shows that a lengthy task is underway, and indicates the percentage of the task that has been completed.

    Page Control
    
    UIPageControl indicates the number of open pages in an application by displaying a dot for each open page. The dot that corresponds to the currently viewed page is highlighted. UIPageControl supports navigation by sending the delegate an event when a user taps to the right or to the left of the currently highlighted dot.
    
    Stepper
    
    Often combined with a label or text field to show the value being incremented.

    Horizontal Stack View
    
    An UIStackView creates and manages the constraints necessary to create horizontal or vertical stacks of views. It will dynamically add and remove its constraints to react to views being removed or added to its stack. With customization it can also react and influence the layout around it.
    
    Vertical Stack View
    
    An UIStackView creates and manages the constraints necessary to create horizontal or vertical stacks of views. It will dynamically add and remove its constraints to react to views being removed or added to its stack. With customization it can also react and influence the layout around it.

    Table View
    
    Coordinates with a data source and delegate to display a scrollable list of rows. Each row in a table view is a UITableViewCell object.
    
    The rows can be grouped into sections, and the sections can optionally have headers and footers.
    
    The user can edit a table by inserting, deleting, and reordering table cells.
    
    Table View Cell
    
    Defines the attributes and behavior of cells in a table view. You can set a table cell's selected-state appearance, support editing functionality, display accessory views (such as a switch control), and specify background appearance and content indentation.

    Image View
    
    Shows an image, or series of images as an animation.
    
    Collection View
    
    Coordinates with a data source and delegate to display a scrollable collection of cells. Each cell in a collection view is a UICollectionViewCell object.
    
    Collection views support flow layout as well a custom layouts, and cells can be grouped into sections, and the sections and cells can optionally have supplementary views.

    var body: some View {
        ScrollView {
            VStack {
                Text(content)
                    .lineLimit(nil)
            }.frame(maxWidth: .infinity)
        }
    }
}

struct ContentView_Previews: PreviewProvider {
    static var previews: some View {
        ContentView()
    }
}
