任何帮助都将不胜感激

如果你不想使用 UIDocumentInteractionController

时,出现错误Error Domain=NSCocoaErrorDomain Code=518 "The file couldn’t be saved because the specified URL type isn’t supported." UserInfo={NSURL=/private/var/mobile/Containers/Data/Application/5B80A983-5571-44A5-80D7-6A7B065800B5/tmp/instagram.igo}
。 - Rohan SanapSwift 3.0 版本:
@IBAction func shareInstagram(_ sender: Any) {
DispatchQueue.main.async {
//Share To Instagram:
let instagramURL = URL(string: "instagram://app")
if UIApplication.shared.canOpenURL(instagramURL!) {
let imageData = UIImageJPEGRepresentation(image, 100)
let writePath = (NSTemporaryDirectory() as NSString).appendingPathComponent("instagram.igo")
do {
try imageData?.write(to: URL(fileURLWithPath: writePath), options: .atomic)
} catch {
print(error)
}
let fileURL = URL(fileURLWithPath: writePath)
self.documentController = UIDocumentInteractionController(url: fileURL)
self.documentController.delegate = self
self.documentController.uti = "com.instagram.exlusivegram"
if UIDevice.current.userInterfaceIdiom == .phone {
self.documentController.presentOpenInMenu(from: self.view.bounds, in: self.view, animated: true)
} else {
self.documentController.presentOpenInMenu(from: self.IGBarButton, animated: true)
}
} else {
print(" Instagram is not installed ")
}
}
}
请尝试使用此代码。
@IBAction func shareContent(sender: UIButton) {
let image = UIImage(named: "imageName")
let objectsToShare: [AnyObject] = [image!]
let activityViewController = UIActivityViewController(
activityItems: objectsToShare,
applicationActivities: nil
)
activityViewController.popoverPresentationController?.sourceView = self.view
activityViewController.excludedActivityTypes = [
UIActivityTypeAirDrop,
UIActivityTypePostToFacebook
]
self.presentViewController(
activityViewController,
animated: true,
completion: nil
)
}
