如何在iOS 11中换行较长的大标题? [英] How to line break long large title in iOS 11?

问题描述

我正在尝试使用Swift在iOS 11中使用新的大型标题系统.当标题过长时(请参见图像示例)，它会添加...而不是换行或缩小文本大小.如何添加换行符?

I am trying to use the new large title system in iOS 11 using Swift. When the title gets too long (see image example), it adds ... instead of line breaking or shrinking the text size. How can I add a line break?

以下是我用来设置标题的一些代码:

Here is some of the code I'm using to set up the title:

self.navigationController?.navigationBar.prefersLargeTitles = true
self.navigationController?.navigationBar.largeTitleTextAttributes = [NSForegroundColorAttributeName: MyGlobalVariable.themeMainColor]
self.navigationController?.navigationBar.largeTitleTextAttributes = [NSFontAttributeName: UIFont.systemFont(ofSize: 22)]
navigationItem.title = "Search by Name"

推荐答案

尝试一下:

for navItem in (self.navigationController?.navigationBar.subviews)! {
    for itemSubView in navItem.subviews {
        if let largeLabel = itemSubView as? UILabel {
            largeLabel.text = self.title
            largeLabel.numberOfLines = 0
            largeLabel.lineBreakMode = .byWordWrapping
        }
    }
}

对我有用.
