【问题描述】：

这在 iOS 8 上运行良好，但在 iOS 9 上，UIDocumentInteractionController 确实出现了带有复制到 Instagram 的选项。按下它只会关闭控制器。

我们将不胜感激。

谢谢，

    var docController = UIDocumentInteractionController()
    let instagramURL = NSURL(string: "instagram://app")

    if(UIApplication.sharedApplication().canOpenURL(instagramURL!)) {
        var imagePost = cropped
        let fullPath = documentsDirectory().stringByAppendingString("insta.igo")
        var imageData = UIImagePNGRepresentation(imagePost!)!.writeToFile(fullPath, atomically: true)
        let rect = CGRectMake(0, 0, 0, 0)
        self.docController.UTI = "com.instagram.exclusivegram"
        let igImageHookFile = NSURL(string: "file://\(fullPath)")
        self.docController = UIDocumentInteractionController(URL: igImageHookFile!)

        self.docController.presentOpenInMenuFromRect(rect, inView: self.view, animated: true)

    }

    func documentsDirectory() -> String {
    let documentsFolderPath = NSSearchPathForDirectoriesInDomains(NSSearchPathDirectory.DocumentDirectory, NSSearchPathDomainMask.UserDomainMask, true)[0]
    return documentsFolderPath
}

【解决方案1】：

iOS9 在声明“insta.igo”时的读取方式，现在需要有“/”

let fullPath = documentsDirectory().stringByAppendingString("/insta.igo")

完整代码

var docController = UIDocumentInteractionController()
let instagramURL = NSURL(string: "instagram://app")

if(UIApplication.sharedApplication().canOpenURL(instagramURL!)) {
    var imagePost = cropped
    let fullPath = documentsDirectory().stringByAppendingString("/insta.igo")
    var imageData = UIImagePNGRepresentation(imagePost!)!.writeToFile(fullPath, atomically: true)
    let rect = CGRectMake(0, 0, 0, 0)
    self.docController.UTI = "com.instagram.exclusivegram"
    let igImageHookFile = NSURL(string: "file://\(fullPath)")
    self.docController = UIDocumentInteractionController(URL: igImageHookFile!)

    self.docController.presentOpenInMenuFromRect(rect, inView: self.view, animated: true)

}

func documentsDirectory() -> String {
let documentsFolderPath = NSSearchPathForDirectoriesInDomains(NSSearchPathDirectory.DocumentDirectory, NSSearchPathDomainMask.UserDomainMask, true)[0]
return documentsFolderPath

【讨论】：

旁注：对于类/VC，var docController = UIDocumentInteractionController() 应该是全局的，不要把它放在func 中。试试@noobsmcgoobs。
@John 我非常感谢你，你的评论本身应该是一个答案，我会支持它。
