当我创建导航栏时,我可以放置左侧项目,右侧项目和标题视图中的三个按钮,但只有左侧和右侧项目有动画,我无法更改标题按钮的颜色。
在导航栏中创建按钮:
self.navigationItem.leftBarButtonItem = UIBarButtonItem(title: "VOYAGE", style: UIBarButtonItemStyle.Plain, target: self, action: "goToPage1:")
var buttonCenter = UIButton()
buttonCenter.setTitle("PHOTOS", forState: .Normal)
buttonCenter.setTitleColor(UIColor.whiteColor(), forState: .Normal)
buttonCenter.addTarget(self, action: "goToPage2:", forControlEvents: .TouchUpInside)
self.navigationItem.titleView = buttonCenter
self.navigationItem.rightBarButtonItem = UIBarButtonItem(title: "SIGHTINGS", style: UIBarButtonItemStyle.Plain, target: self, action: "goToPage3:")
触摸按钮时颜色的变化:
功能goToPage1:
self.navigationItem.leftBarButtonItem!.tintColor = UIColor(red: 174/255, green: 211/255, blue: 43/255, alpha: 1)
self.navigationItem.titleView!.tintColor = UIColor.whiteColor()
self.navigationItem.rightBarButtonItem!.tintColor = UIColor.whiteColor()
功能goToPage2:
self.navigationItem.leftBarButtonItem!.tintColor = UIColor.whiteColor()
self.navigationItem.titleView!.tintColor = UIColor(red: 174/255, green: 211/255, blue: 43/255, alpha: 1)
self.navigationItem.rightBarButtonItem!.tintColor = UIColor.whiteColor()
功能goToPage3:
self.navigationItem.leftBarButtonItem!.tintColor = UIColor.whiteColor()
self.navigationItem.titleView!.tintColor = UIColor.whiteColor()
self.navigationItem.rightBarButtonItem!.tintColor = UIColor(red: 174/255, green: 211/255, blue: 43/255, alpha: 1)
您对按钮的选择动画有什么想法吗?
