xcode - Swift 2 - 使用 UIActivityViewController 分享视频

Question

我正在尝试使用 UIActivityViewController 从 URL 分享视频。
如果我尝试使用图像，我没有问题。

分享图片作品:

let imageThump = NSURL(string: "https://example.com/image.png")
let imageData = NSData(contentsOfURL: imageThump!) 
let objectsToShare = [comment!, imageData!]
let activityVC = UIActivityViewController(activityItems: objectsToShare, applicationActivities: nil)

共享视频不起作用。为什么？

let videoShare = NSURL(string: "https://example.com/video.mp4")
let videoData = NSData(contentsOfURL: videoShare!) 
let objectsToShare = [comment!, videoData!]
let activityVC = UIActivityViewController(activityItems: objectsToShare, applicationActivities: nil)

Answer 1

这就是你如何做的......

guard let urlData = NSData(contentsOfURL: NSURL(string:"https://example.com/video.mov)")!) else { 
    return 
}

print(urlData)


let paths = NSSearchPathForDirectoriesInDomains(.DocumentDirectory, .UserDomainMask, true)
let docDirectory = paths[0]
let filePath = "\(docDirectory)/tmpVideo.mov"
urlData?.writeToFile(filePath, atomically: true)
// File Saved

let videoLink = NSURL(fileURLWithPath: filePath)


let objectsToShare = [videoLink] //comment!, imageData!, myWebsite!]
let activityVC = UIActivityViewController(activityItems: objectsToShare, applicationActivities: nil)

activityVC.setValue("Video", forKey: "subject")


// New Excluded Activities Code
if #available(iOS 9.0, *) {
    activityVC.excludedActivityTypes = [UIActivityTypeAirDrop, UIActivityTypeAddToReadingList, UIActivityTypeAssignToContact, UIActivityTypeCopyToPasteboard, UIActivityTypeMail, UIActivityTypeMessage, UIActivityTypeOpenInIBooks, UIActivityTypePostToTencentWeibo, UIActivityTypePostToVimeo, UIActivityTypePostToWeibo, UIActivityTypePrint]
} else {
    // Fallback on earlier versions
    activityVC.excludedActivityTypes = [UIActivityTypeAirDrop, UIActivityTypeAddToReadingList, UIActivityTypeAssignToContact, UIActivityTypeCopyToPasteboard, UIActivityTypeMail, UIActivityTypeMessage, UIActivityTypePostToTencentWeibo, UIActivityTypePostToVimeo, UIActivityTypePostToWeibo, UIActivityTypePrint ]
}

           
self.presentViewController(activityVC, animated: true, completion: nil)
