问题描述
是否可以绕过Action Share Sheet向Instagram分享图片?
Would it be possible to share a picture to Instagram bypassing the Action Share Sheet?
请注意,我意识到 了UIDocumentInteractionController
和钩子,实际上它可以正常工作.通过他们的示例代码,您可以得到Copy to Instagram
选项(如果使用专有的UTI,则为唯一;或者可以与Instagram一起使用的可处理JPG/PNG的大量应用程序).
Please Note that I am aware of the UIDocumentInteractionController
and the hooks and in fact it works fine. With their sample code you get a Copy to Instagram
option (either unique if you use the exclusive UTI or a big list of apps which can handle a JPG/PNG, alongside with Instagram).
这很好用,但是我想知道是否有一种方法可以执行操作复制到Instagram",而无需在iOS 9+中显示UIDocumentInteractionController
菜单.
This works fine, but I'd like to know if there's a way to execute the action "Copy to Instagram" without the need to present the UIDocumentInteractionController
menu in iOS 9+.
为了便于记录,这是一个完美的代码简化版本.假设您有一个有效的NSURL ...
For the record this is a simplified version of the code that works perfectly. Assuming you have a valid NSURL…
guard let data: NSData = NSData(contentsOfURL: url),
image = UIImage(data: data) else {
return
}
let imageData = UIImageJPEGRepresentation(image, 100)
let captionString = "caption"
let writePath = (NSTemporaryDirectory() as NSString).stringByAppendingPathComponent("instagram.ig")
guard let _ = imageData?.writeToFile(writePath, atomically: true) else {
return
}
let fileURL = NSURL(fileURLWithPath: writePath)
self.documentController = UIDocumentInteractionController(URL: fileURL)
self.documentController.delegate = self
self.documentController.UTI = "com.instagram.photo"
self.documentController.annotation = NSDictionary(object: captionString, forKey: "InstagramCaption")
self.documentController.presentOpenInMenuFromRect(viewController.view.frame, inView: viewController.view, animated: true)
问题 是,这将显示一个操作表",如果可能的话,我想避免这样做,我想使用instagram.ige
(或其他使它排他的名称) )并跳过此ActionSheet.
The problem is that this will present an "Action Sheet" and I want to avoid doing that if possible, I want to use instagram.ige
(or whatever the name it was to make it exclusive) and skip this ActionSheet.
有可能吗?
更新:我还没有找到解决方案,但似乎Instagram终于在添加/添加了扩展程序:"Instagram最近在其iOS应用程序中添加了共享扩展程序功能.现在,您可以共享将来自第三方应用程序的照片直接发送到Instagram"来源: http://www.macworld.com/article/3080038/data-center-cloud/new-instagram-feature-for-ios-makes-it-easier-to -share-photos-from-other-apps.html
UPDATE: I haven't found a solution for this, but seems like Instagram finally is adding/added extensions: "Instagram recently added sharing extensions functionality to its iOS app. Now, you can share photos from third-party apps directly to Instagram"source: http://www.macworld.com/article/3080038/data-center-cloud/new-instagram-feature-for-ios-makes-it-easier-to-share-photos-from-other-apps.html
推荐答案
更新的Swift 4.2代码
import Photos
func postImageToInstagram(image: UIImage) {
UIImageWriteToSavedPhotosAlbum(
image,
self,
#selector(self.image(image:didFinishSavingWithError:contextInfo:)),
nil
)
}
@objc func image(image: UIImage, didFinishSavingWithError error: NSError?, contextInfo: UnsafeRawPointer) {
if let err = error {
print(err) // TODO: handle error
return
}
let fetchOptions = PHFetchOptions()
fetchOptions.sortDescriptors = [NSSortDescriptor(key: "creationDate", ascending: false)]
let fetchResult = PHAsset.fetchAssets(with: .image, options: fetchOptions)
if let lastAsset = fetchResult.firstObject {
let localIdentifier = lastAsset.localIdentifier
let u = "instagram://library?AssetPath=" + localIdentifier
let url = URL(string: u)!
if UIApplication.shared.canOpenURL(url) {
UIApplication.shared.open(url, options: [:], completionHandler: nil)
} else {
let alertController = UIAlertController(title: "Error", message: "Instagram is not installed", preferredStyle: .alert)
alertController.addAction(UIAlertAction(title: "OK", style: .default, handler: nil))
self.present(alertController, animated: true, completion: nil)
}
}
}
原始答案
import Photos
...
func postImageToInstagram(image: UIImage) {
UIImageWriteToSavedPhotosAlbum(image, self, #selector(SocialShare.image(_:didFinishSavingWithError:contextInfo:)), nil)
}
func image(image: UIImage, didFinishSavingWithError error: NSError?, contextInfo:UnsafePointer<Void>) {
if error != nil {
print(error)
}
let fetchOptions = PHFetchOptions()
fetchOptions.sortDescriptors = [NSSortDescriptor(key: "creationDate", ascending: false)]
let fetchResult = PHAsset.fetchAssetsWithMediaType(.Image, options: fetchOptions)
if let lastAsset = fetchResult.firstObject as? PHAsset {
let localIdentifier = lastAsset.localIdentifier
let u = "instagram://library?LocalIdentifier=" + localIdentifier
let url = NSURL(string: u)!
if UIApplication.sharedApplication().canOpenURL(url) {
UIApplication.sharedApplication().openURL(NSURL(string: u)!)
} else {
let alertController = UIAlertController(title: "Error", message: "Instagram is not installed", preferredStyle: .Alert)
alertController.addAction(UIAlertAction(title: "OK", style: .Default, handler: nil))
self.presentViewController(alertController, animated: true, completion: nil)
}
}
}
