1 SLComposeViewController

SLComposeViewController主要用于在当前应用开启分享界面，快速分享相关内容到其他APP或社交平台。如下所示

1.1 Creating a Social Compose View Controller

/// 根据扩展的Bundle identifier初始化
public init!(forServiceType serviceType: String!)

1.2 Checking the Social Service Type

/// 判断该分享扩展是否支持
public class func isAvailableForServiceType(serviceType: String!) -> Bool

/// 获取分享扩展的类型编码
public var serviceType: String! { get }

1.3 Composing Posts

/// 设置默认内容
public func setInitialText(text: String!) -> Bool

/// 添加图片
public func addImage(image: UIImage!) -> Bool

/// 清空所有图片
public func removeAllImages() -> Bool

/// 添加url链接
public func addURL(url: NSURL!) -> Bool

/// 清空所有链接
public func removeAllURLs() -> Bool

1.4 Handling Results

/// 分享结果监听
public var completionHandler: SLComposeViewControllerCompletionHandler!

import UIKit

/// 快速分享
class ViewController: UIViewController {

    override func viewDidLoad() {
        super.viewDidLoad()
        // Do any additional setup after loading the view, typically from a nib.
    }

    override func touchesBegan(touches: Set<UITouch>, withEvent event: UIEvent?) {
        super.touchesBegan(touches, withEvent: event)
        // 分享到当前应用扩展（微博分享SLServiceTypeSinaWeibo）
        let serviceType = "com.YJSocial.ShareExtension" // 扩展Bundle identifier
        guard SLComposeViewController.isAvailableForServiceType(serviceType) else {
            print("不支持:\(serviceType)")
            return
        }
        let vc = SLComposeViewController(forServiceType: serviceType)
        vc.setInitialText(serviceType) // 默认内容
        // 处理结果回调
        vc.completionHandler =  {(result: SLComposeViewControllerResult) -> Void in
            switch result {
            case SLComposeViewControllerResult.Cancelled:
                print("Cancelled")
            case SLComposeViewControllerResult.Done:
                print("Done")
            }
        }
        self.presentViewController(vc, animated: true, completion: nil)
    }

}
