6 通过给xib拖线,拿到内部属性
//按钮头像
@IBOutlet weak var iconButton: UIButton!
//头部子标题
@IBOutlet weak var subtitleLabel: UILabel!
//头部标题
@IBOutlet weak var title_Label: UILabel!
7 给xib中的属性提供set方法和对应的get方法,方便外边调用修改
//对头部标题提供Set方法
var title : String? {
didSet{
return title_Label.text = title
}
}
//对头部子标题提供set方法
var subtitle : String? {
didSet{
return subtitleLabel.text = subtitle
}
}
//对按钮头像提供set方法(平常的图片)
var normalName : String? {
didSet{
return iconButton.setImage(UIImage(named: normalName!), forState: .Normal)
}
}
//对按钮头像提供set方法(点击后的图片)
var heightName : String? {
didSet{
return iconButton.setImage(UIImage(named: heightName!), forState: .Highlighted)
}
}
//对按钮提供一个get方法
var getIconButton : UIButton {
get{
return iconButton
}
}
8 提供一个加载xib的类方法,让外界能通过该方法快速创建xib
//MARK: - 给类扩展一个方法(加载xib)
extension XFJTopView {
//提供一个快速创建xib的类方法
class func topView(title : String, subTitle : String, normalImageName : String, heightImageName : String) ->XFJTopView {
let topView = NSBundle.mainBundle().loadNibNamed("XFJTopView", owner: nil, options: nil).last! as! XFJTopView
//给属性赋值
topView.title_Label.text = title
topView.subtitleLabel.text = subTitle
topView.iconButton.setImage(UIImage(named: normalImageName), forState: .Normal)
topView.iconButton.setImage(UIImage(named: heightImageName), forState: .Highlighted)
//返回通过xib创建的对象
return topView
}
}
9 添加顶部的按钮
—-> 9.1 思路 : 通过添加到由导航条管理的item中的数组中来实现对加载xib的时候按钮的添加
—-> 9.2 导航控制器的根控制器
—-> 9.3 XFJHomeViewController类对导航条中的item的管理(该部分代码比较多,我们通过类扩展来实现)
//MARK: - 设置导航条中的item
extension XFJHomeViewController {
@objc private func setUpTabBarItem() {
//设置值item的图片(0)
let logoItem = UIBarButtonItem(image: UIImage(named: "icon_meituan_logo"), style: .Plain, target: nil, action: nil)
//对导航条最左边的item赋值
navigationItem.leftBarButtonItem = logoItem
//取消导航条左边的item点击
logoItem.enabled = false
//设置其他的items(一)
let item1 = XFJTopView.topView("美团", subTitle: "全部分类", normalImageName: "icon_category_-1", heightImageName: "icon_category_highlighted_-1")
//设置第一个item
let topItem = UIBarButtonItem(customView: item1)
//对按钮的监听
item1.getIconButton.addTarget(self, action: "presentPopTopViewClick", forControlEvents: .TouchUpInside)
//赋值
self.topItem = topItem
//设置items(二)
let item2 = XFJTopView.topView("广州", subTitle: "全部", normalImageName: "icon_district", heightImageName: "icon_district_highlighted")
let gzItem = UIBarButtonItem(customView: item2)
item2.getIconButton.addTarget(self, action: "presentPopGzViewClick", forControlEvents: .TouchUpInside)
//赋值
self.gzItem = gzItem
//设置items(三)
let item3 = XFJTopView.topView("排序", subTitle: "默认排序", normalImageName: "icon_sort", heightImageName: "icon_sort_highlighted")
let sortItem = UIBarButtonItem(customView: item3)
item3.getIconButton.addTarget(self, action: "presentPopSortViewClick", forControlEvents: .TouchUpInside)
//赋值
self.sortItem = sortItem
//将item添加到数组中
navigationItem.leftBarButtonItems = [logoItem,topItem,gzItem,sortItem]
}
}
