ios - UIDocumentInteractionController PresentOpenInMenuFromRect

Question

我有从 UIAlertController 中调用的代码:

func createSomeFile() {

    var output = (some NSData to output to file)


    let fileName = NSTemporaryDirectory().stringByAppendingPathComponent("filename.ext")
    let url: NSURL! = NSURL(fileURLWithPath: fileName)

    var dataToWrite = output.dataUsingEncoding(NSUTF8StringEncoding)
    dataToWrite?.writeToFile(url.absoluteString!, atomically: true)

    documentController = UIDocumentInteractionController(URL: url)
    documentController.UTI = "com.someUTI"
    documentController.delegate = self

    documentController.presentOpenInMenuFromRect(CGRectZero, inView: self, animated: true)
}

最后一行在 Xcode 中引发错误:“无法使用类型的参数列表调用 'presentOpenInMenuFromRect'...”

documentController 被声明为类变量var documentController = UIDocumentInteractionController()

请帮我解决这个问题。

Answer 1

您无法分配 self一个参数应该是 UIView (除非 self 是 UIView 的子类，但显然不是)

所以试试这个:

documentController.presentOpenInMenuFromRect(CGRectZero, inView: self.view, animated: true)
