我有下图，其中下拉菜单标题与其他按钮重叠。 如何解决这个问题？
代码:
func createDropDownMenu() {
// create the drop down menu
let title = prepareNavigationBarMenuTitleView()
prepareNavigationBarMenu(title)
updateMenuContentOffsets()
}
func prepareNavigationBarMenuTitleView() -> String {
// Both title label and image view are fixed horizontally inside title
// view, UIKit is responsible to center title view in the navigation bar.
// We want to ensure the space between title and image remains constant,
// even when title view is moved to remain centered (but never resized).
titleView = DropDownTitleView(frame: CGRect(x: 0, y: 0, width: 150, height: 40))
titleView.addTarget(self,
action: #selector(DocumentViewController.willToggleNavigationBarMenu(_:)),
for: .touchUpInside)
titleView.addTarget(self,
action: #selector(DocumentViewController.didToggleNavigationBarMenu(_:)),
for: .valueChanged)
titleView.titleLabel.lineBreakMode = NSLineBreakMode.byClipping
titleView.titleLabel.numberOfLines = 2
titleView.titleLabel.textColor = UIColor.black
titleView.title = currentNode.title
navigationItem.titleView = titleView
return titleView.title!
}
最佳答案
我必须设置 TitleLable 的框架并设置 numberOfLines = 0 来解决我的问题。
代码:
titleView.titleLabel.frame = CGRect(x: 0, y: 0, width: 600, height: 80)
titleView.numberOfLines = 0
titleView.titleLabel.text = currentNode.title
