第一种:一个比较好用的第三方:STPickerView
(地址:https://github.com/STShenZhaoliang/STPickerView)

在需要点击的地方添加以下代码:

           let pickerAre = STPickerArea()
           pickerAre.delegate = self
            
            pickerAre.show()
//并实现代理方法:
 func pickerArea(pickerArea: STPickerArea, province: String, city: String, area: String) {
  adressTF.text = "\(province)\(city)\(area)"
 UIView.animateWithDuration(0.25) {
     self.scrollView.contentOffset = CGPointZero
        }
  }

即可实现以下效果

最近突然提出的需求就是这种样式,直接导入demo,桥接一下头文件,用swift方式调用一下代码就可以轻松实现

override func viewDidLoad() {
    CitiesDataTool.sharedManager().requestGetData()
}

override func gestureRecognizerShouldBegin(gestureRecognizer:UIGestureRecognizer) -> Bool {
    
    let point = gestureRecognizer.locationInView(gestureRecognizer.view)
    
    if CGRectContainsPoint(self.chooseLocationView.frame, point) {
        return false
    }
    return true
}

//点击空白处收回控制器
func tapCover(tap:UITapGestureRecognizer){
    if (chooseLocationView.chooseFinish != nil) {
        self.chooseLocationView.chooseFinish()

    }
}

//MARK:属性

lazy var cover:UIView = {
    
    let cover = UIView(frame: UIScreen.mainScreen().bounds)
    
    //        cover.backgroundColor = UIColor.whiteColor()
    //        cover.alpha = 0.5
    cover.backgroundColor = UIColor.init(white: 1, alpha: 0.2)
    
    UIApplication.sharedApplication().keyWindow?.addSubview(cover)
    
    self.chooseLocationView = ChooseLocationView(frame: CGRect(x: 0, y: UIScreen.mainScreen().bounds.size.height - 300, width: UIScreen.mainScreen().bounds.size.width, height: 300))
    cover.addSubview(self.chooseLocationView)
    
    
    self.chooseLocationView.chooseFinish = { (AnyObject) -> () in
        
        UIView.animateWithDuration(0.25, animations: {
            self.adressTF.text = self.chooseLocationView.address
            self.view.transform = CGAffineTransformIdentity
            cover.hidden = true;
        })
        
    }
    
    let tap = UITapGestureRecognizer(target: self, action: #selector(tapCover(_:)))
    
    cover.addGestureRecognizer(tap)
    
    tap.delegate = self;
    
    cover.hidden = true;
    
    return cover
    
}()

需要点击的地方添加:

 UIView.animateWithDuration(0.25, animations: {
                self.view.transform = CGAffineTransformMakeScale(0.95, 0.95)
            })
            self.cover.hidden = !self.cover.hidden;
            self.chooseLocationView.hidden = self.cover.hidden;

实现效果:
