昨天有网友说我写的那段系统分享代码在iOS9上有warning，看下了原来ios8之后UIPopoverController被废弃了。新增加的UIPopoverPresentationController在控制PopView上更简单好用。

下面是我修改之后的代码：

1. 在app内以子视图方式打开其他app预览，仅支持6.0以上

openAppWithIdentifier(appId: String)

2. 分享文字图片信息，ipad上会以sourceView为焦点弹出选择视图

share(textToShare: String, url: String, image: UIImage, sourceView: UIView)

/// 在app内以子视图方式打开其他app预览，仅支持6.0以上    private func openAppWithIdentifier(appId: String) {        if let _ = NSClassFromString("SKStoreProductViewController") { let storeProductViewController = SKStoreProductViewController() storeProductViewController.delegate = self let dict = NSDictionary(object:appId, forKey:SKStoreProductParameterITunesItemIdentifier) as! [String : AnyObject] storeProductViewController.loadProductWithParameters(dict, completionBlock: { (result, error) -> Void in // self.presentViewController(storeProductViewController, animated: true, completion: nil) }) self.presentViewController(storeProductViewController, animated: true, completion: nil) }else { UIApplication.sharedApplication().openURL(NSURL(string: "itms-apps://itunes.apple.com/app/id\(appId)")!) } } /// 分享文字图片信息，ipad上会以sourceView为焦点弹出选择视图 private func share(textToShare: String, url: String, image: UIImage, sourceView: UIView) { let objectsToShare = [textToShare, url, image] let activityViewController = UIActivityViewController(activityItems: objectsToShare, applicationActivities: nil) if UIDevice.currentDevice().userInterfaceIdiom == UIUserInterfaceIdiom.Phone { self.presentViewController(activityViewController, animated: true, completion: nil) }else { let popover = activityViewController.popoverPresentationController if (popover != nil){ popover?.sourceView = sourceView popover?.sourceRect = sourceView.frame popover?.permittedArrowDirections = UIPopoverArrowDirection.Any self.presentViewController(activityViewController, animated: true, completion: nil) } } }
