cancelButton 显示不全

[xclidongbo]

let searchVC: PYSearchViewController = PYSearchViewController(hotSearches: [], searchBarPlaceholder: "输入关键字进行搜索")
        searchVC.cancelButton.setTitleColor(CELL_TITLE_COLOR, for: .normal)
        searchVC.hotSearchStyle = PYHotSearchStyle.default
        searchVC.searchHistoryStyle = PYSearchHistoryStyle.normalTag
        searchVC.searchBarBackgroundColor = UIColor(hex: 0xEDF2F8)
        searchVC.delegate = self
        searchVC.searchBarCornerRadius = 15

已经解决. 需要用约束设置cancelButton的宽度. frame方式设置无效.

searchVC.cancelButton.widthAnchor.constraint(equalToConstant: 32).isActive = true
searchVC.cancelButton.heightAnchor.constraint(equalToConstant: 32).isActive = true
