我右侧有一个简单的+按钮,可以在tableView中添加行,但按钮没有出现。这就是我实现它的方式
let AddButton = UIButton()
AddButton.setTitle("+", forState: .Normal)
let AddView = UIBarButtonItem(customView: AddButton)
self.navigationItem.rightBarButtonItem = AddView
AddButton.addTarget(self, action: #selector(self.addRow), forControlEvents: UIControlEvents.TouchUpInside)
注意,我使用与我的汉堡包按钮完全相同的实现方式。这是工作汉堡包按钮实现
let navicon = UIButton(type: UIButtonType.System)
navicon.setImage(defaultMenuImage(), forState: UIControlState.Normal)
navicon.frame = CGRectMake(0, 0, 30, 30)
let menu = UIBarButtonItem(customView: navicon)
self.navigationItem.leftBarButtonItem = menu
self.view.addGestureRecognizer(self.revealViewController().panGestureRecognizer())
navicon.addTarget(self.revealViewController(), action: #selector(SWRevealViewController.revealToggle(_:)), forControlEvents: .TouchUpInside)
为什么会这样?
答案 0 :(得分:0)
尝试:
let AddButton = UIButton(type: .Custom)
AddButton.frame = CGRectMake(0, 0, 44, 44)
