DOAlertController

DOAlertController	弹出确认取消的层	Swift

调用方式

代码语言：javascript复制

let alertController = DOAlertController(title: "新建文件夹", message: "", preferredStyle: .Alert)
alertController.addTextFieldWithConfigurationHandler { textField in
    textField.placeholder = "请输入文件夹的名称";
}
let cancelAction = DOAlertAction(title: "取消", style: .Cancel, handler: nil)
let okAction = DOAlertAction(title: "确认" ,style: .Default) { action in
    
}
alertController.addAction(cancelAction)
alertController.addAction(okAction)
presentViewController(alertController, animated: true, completion: nil)

Sphere Menu

Sphere Menu	弹出按钮菜单	Swift

调用方式

代码语言：javascript复制

//实现代理 DNImagePickerControllerDelegate

func addMenu() {
    let start = UIImage(named: "start")
    let image1 = UIImage(named: "icon_file_menu_folder")
    let image2 = UIImage(named: "icon_file_menu_img")
    let image3 = UIImage(named: "icon_file_menu_movie")
    let images:[UIImage] = [image1!,image2!,image3!]
    menu = SphereMenu(startPoint: CGPointMake(screenWidth-40, screenHeight-100), startImage: start!, submenuImages:images, tapToDismiss:true)
    menu.delegate = self
    self.view.addSubview(menu)
}

//代理方法

侧滑菜单

RESideMenu

RESideMenu	侧滑菜单	Objective-C

TableViewCell侧滑

MGSwipeTableCell

MGSwipeTableCell	TableViewCell侧滑	Objective-C

调用方式

• 1 引用头文件

代码语言：javascript复制

//侧滑按钮
#import "MGSwipeButton.h"
#import "MGSwipeTableCell.h"

• 2 需要侧滑的tableViewCell继承MGSwipeTableCell
• 3 Controller实现接口MGSwipeTableCellDelegate
• 4 相关代码

代码语言：javascript复制

func createRightButtons() -> Array<MGSwipeButton>{
    var buttonArray = Array<MGSwipeButton>();
    let titleArray = [
        "",
        //""
    ];
    let iconArray = [
        UIImage(named: "cell_cross.png"),
        //UIImage(named: "cell_menu.png"),
    ];
    let backgroundColorArray = [
        UIColor(red: 1, green: 102/255, blue: 102/255, alpha: 1),
        //UIColor(red: 104/255, green: 187/255, blue: 248/255, alpha: 1),
    ];
    
    let insets = UIEdgeInsets(top: 0, left: 30, bottom: 0, right: 30);
    
    for i in 0  ..< titleArray.count  {
        let button = MGSwipeButton(title: titleArray[i], icon: iconArray[i], backgroundColor: backgroundColorArray[i],insets: insets);
        buttonArray.append(button);
    }
    
    return buttonArray;
}
    
func swipeTableCell(cell: MGSwipeTableCell!, tappedButtonAtIndex index: Int, direction: MGSwipeDirection, fromExpansion: Bool) -> Bool {
    if(index == 0){
        let indexPath = tableView.indexPathForCell(cell);
        print("点击了(indexPath)")
    }
    return true;
}

• 5 cell中调用

代码语言：javascript复制

cell.rightButtons = createRightButtons();
cell.rightSwipeSettings.transition = MGSwipeTransition.Border;
cell.delegate = self;

数据库

SQLiteDB

SQLiteDB	操作Sqlite数据库	Swift

调用方式

代码语言：javascript复制

let db = SQLiteDB.sharedInstance()
let data = db.query("SELECT * FROM customers WHERE name='John'")
let row = data[0]
if let name = row["name"] {
    textLabel.text = name as! String
}

数据请求

Swift数据请求常用的三个库

Alamofire	网络请求库	Swift
SwiftyJSON	转JSON	Swift
Alamofire-SwiftyJSON	方便以上两个组件的结合使用	Swift
