    导读:

    实现效果如下图:


    用法:

    直接实例化MOFSAddressPickerView即可。方法func show()调出pickerView

    var pickerView = MOFSAddressPickerView();

    pickerView.mofsDelegate = self;

    //MARK: - MOFSAddressPickerViewDelegate

    func selectedAddress(province: String, city: String, area: String, id: String) {

    }

    点击确定之后协议返回省市区名称及id;

    MOFSAddressPickerView代码:

    import UIKit

    let UISCEEN_WIDTH = UIScreen.mainScreen().bounds.width;

    let UISCEEN_HEIGHT = UIScreen.mainScreen().bounds.height;

    protocol MOFSAddressPickerViewDelegate {  

    func selectedAddress(province: String, city: String, area: String, id: String); 

     }

    class MOFSAddressPickerView: UIPickerView,UIPickerViewDelegate,UIPickerViewDataSource {      

    var mofsDelegate:MOFSAddressPickerViewDelegate!   

    var toolBar = UIToolbar();   

    var containerView = UIView(); //背景View   

    var commitBar:UIBarButtonItem!; //确定UIBarButtonItem   

    var cancelBar:UIBarButtonItem!; //取消UIBarButtonItem       

    var provinceArr:Array= Array();

    var selectedIndex_province = 0; //选中的省

    var selectedIndex_city = 0; //选中的市

    var selectedIndex_area = 0; //选中的区

    /*

    *pickerView高度

    *默认216;

    */

    var height:CGFloat! {

    didSet {

    self.frame = CGRectMake(0, UISCEEN_HEIGHT - height, UISCEEN_WIDTH, height);

    toolBar.frame = CGRectMake(0, UISCEEN_HEIGHT - height - 44, UISCEEN_WIDTH, 44);

    containerView.frame = CGRectMake(0, 0, UISCEEN_WIDTH, UISCEEN_HEIGHT - height - 44);

    }

    }

    /*

    *cancelBar的title

    *默认为“取消”

    */

    var cancelBarTitle:String! {

    didSet {

    cancelBar.title = cancelBarTitle;

    }

    }

    /*

    *cancelBar的文字颜色

    *默认UIColor(hexString: "0079fe")

    */

    var cancelBarColor:UIColor! {

    didSet {

    cancelBar.tintColor = cancelBarColor;

    }

    }

    /*

    *commitBar的title

    *默认为“确定”

    */

    var commitBarTitle:String! {

    didSet {

    commitBar.title = commitBarTitle;

    }

    }

    /*

    *commitBar的文字颜色

    *默认UIColor(hexString: "0079fe")

    */

    var commitBarColor:UIColor! {

    didSet {

    commitBar.tintColor = commitBarColor;

    }

    }

    //MARK: - self.init

    override init(frame: CGRect) {

    var initialFrame:CGRect!;

    if (CGRectIsEmpty(frame)) {

    initialFrame = CGRectMake(0, UISCEEN_HEIGHT - 216, UISCEEN_WIDTH, 216);

    } else {

    initialFrame = frame;

    }

    initialFrame = CGRectMake(0, UISCEEN_HEIGHT - initialFrame.height, UISCEEN_WIDTH, initialFrame.height);

    super.init(frame: initialFrame);

    self.backgroundColor = UIColor(hexString: "#F6F6F6");

    self.delegate = self;

    self.dataSource = self;

    self.getData();

    self.initToolBar();
