iOSのInstagramで画像を共有する方法は？
私のクライアントは、Instagram、Twitter、Facebookで画像を共有したいと考えています。
TwitterやFacebookを使ったことがありますが、Instagramで画像を共有するためのAPIやインターネット上のものは見つかりませんでした。 Instagramで画像を共有することは可能ですか？はいの場合はどうですか？
Instagramの開発者向けサイトを確認すると、RubyおよびPythonでRailsのライブラリが見つかりました。しかし、iOS Sdkのドキュメントはありません
Instagram.com/developerに従ってinstagramからトークンを取得しましたが、instagram画像と共有するための次のステップをどうすればよいかわかりません。
最終的に私は答えを得た。 Instagramに画像を直接投稿することはできません。 UIDocumentInteractionControllerを使用して画像を再編集する必要があります。
@property (nonatomic, retain) UIDocumentInteractionController *dic;
CGRect rect = CGRectMake(0 ,0 , 0, 0);
UIGraphicsBeginImageContextWithOptions(self.view.bounds.size, self.view.opaque, 0.0);
[self.view.layer renderInContext:UIGraphicsGetCurrentContext()];
UIGraphicsEndImageContext();
NSString *jpgPath = [NSHomeDirectory() stringByAppendingPathComponent:@"Documents/test.igo"];
NSURL *igImageHookFile = [[NSURL alloc] initWithString:[[NSString alloc] initWithFormat:@"file://%@", jpgPath]];
self.dic.UTI = @"com.instagram.photo";
self.dic = [self setupControllerWithURL:igImageHookFile usingDelegate:self];
self.dic=[UIDocumentInteractionController interactionControllerWithURL:igImageHookFile];
[self.dic presentOpenInMenuFromRect: rect inView: self.view animated: YES ];
- (UIDocumentInteractionController *) setupControllerWithURL: (NSURL*) fileURL usingDelegate: (id <UIDocumentInteractionControllerDelegate>) interactionDelegate {
UIDocumentInteractionController *interactionController = [UIDocumentInteractionController interactionControllerWithURL: fileURL];
interactionController.delegate = interactionDelegate;
return interactionController;
}
注：instagramアプリにリダイレクトすると、アプリに戻ることはできません。アプリをもう一度開く必要があります

この回答があなたの質問を解決することを願っています。これにより、カメラではなくInstagramのライブラリフォルダーが直接開きます。
NSURL *instagramURL = [NSURL URLWithString:@"instagram://app"];
if ([[UIApplication sharedApplication] canOpenURL:instagramURL])
{
NSURL *videoFilePath = [NSURL URLWithString:[NSString stringWithFormat:@"%@",[request downloadDestinationPath]]]; // Your local path to the video
NSString *caption = @"Some Preloaded Caption";
ALAssetsLibrary *library = [[ALAssetsLibrary alloc] init];
[library writeVideoAtPathToSavedPhotosAlbum:videoFilePath completionBlock:^(NSURL *assetURL, NSError *error) {
NSString *escapedString = [self urlencodedString:videoFilePath.absoluteString];
NSString *escapedCaption = [self urlencodedString:caption];
NSURL *instagramURL = [NSURL URLWithString:[NSString stringWithFormat:@"instagram://library?AssetPath=%@&InstagramCaption=%@",escapedString,escapedCaption]];
if ([[UIApplication sharedApplication] canOpenURL:instagramURL]) {
[[UIApplication sharedApplication] openURL:instagramURL];
}
}];
IOS 6以降では、このUIActivityを使用して、画像をInstagramにアップロードできます。Instagramは、iOSフックを使用した同じワークフローを持ちますが、開発を簡素化します。
uIDocumentInteractionControllerを使用したくない場合
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)
}
}
}
これは私が詳細に実装する正解です。 .hファイル内
UIImageView *imageMain;
@property (nonatomic, strong) UIDocumentInteractionController *documentController;
in.mファイルのみ書き込み
NSURL *instagramURL = [NSURL URLWithString:@"instagram://app"];
if([[UIApplication sharedApplication] canOpenURL:instagramURL])
{
CGFloat cropVal = (imageMain.image.size.height > imageMain.image.size.width ? imageMain.image.size.width : imageMain.image.size.height);
cropVal *= [imageMain.image scale];
CGRect cropRect = (CGRect){.size.height = cropVal, .size.width = cropVal};
CGImageRef imageRef = CGImageCreateWithImageInRect([imageMain.image CGImage], cropRect);
NSData *imageData = UIImageJPEGRepresentation([UIImage imageWithCGImage:imageRef], 1.0);
CGImageRelease(imageRef);
NSString *writePath = [NSTemporaryDirectory() stringByAppendingPathComponent:@"instagram.igo"];
if (![imageData writeToFile:writePath atomically:YES]) {
// failure
NSLog(@"image save failed to path %@", writePath);
return;
} else {
// success.
}
// send it to instagram.
NSURL *fileURL = [NSURL fileURLWithPath:writePath];
self.documentController = [UIDocumentInteractionController interactionControllerWithURL:fileURL];
self.documentController.delegate = self;
[self.documentController setUTI:@"com.instagram.exclusivegram"];
[self.documentController setAnnotation:@{@"InstagramCaption" : @"We are making fun"}];
[self.documentController presentOpenInMenuFromRect:CGRectMake(0, 0, 320, 480) inView:self.view animated:YES];
}
else
{
NSLog (@"Instagram not found");
}
確かに結果が得られます。たとえば、下からポップオーバーがInstagramイメージとともに表示されます。クリックして楽しんでください。
私は自分のアプリケーションでこれを試しましたが、完全に動作しています（Swift）
import Foundation
import UIKit
class InstagramManager: NSObject, UIDocumentInteractionControllerDelegate {
private let kInstagramURL = "instagram://"
private let kUTI = "com.instagram.exclusivegram"
private let kfileNameExtension = "instagram.igo"
private let kAlertViewTitle = "Error"
private let kAlertViewMessage = "Please install the Instagram application"
var documentInteractionController = UIDocumentInteractionController()
// singleton manager
class var sharedManager: InstagramManager {
struct Singleton {
static let instance = InstagramManager()
}
return Singleton.instance
}
func postImageToInstagramWithCaption(imageInstagram: UIImage, instagramCaption: String, view: UIView) {
// called to post image with caption to the instagram application
let instagramURL = NSURL(string: kInstagramURL)
if UIApplication.sharedApplication().canOpenURL(instagramURL!) {
let jpgPath = (NSTemporaryDirectory() as NSString).stringByAppendingPathComponent(kfileNameExtension)
UIImageJPEGRepresentation(imageInstagram, 1.0)!.writeToFile(jpgPath, atomically: true)
let rect = CGRectMake(0,0,612,612)
let fileURL = NSURL.fileURLWithPath(jpgPath)
documentInteractionController.URL = fileURL
documentInteractionController.delegate = self
documentInteractionController.UTI = kUTI
// adding caption for the image
documentInteractionController.annotation = ["InstagramCaption": instagramCaption]
documentInteractionController.presentOpenInMenuFromRect(rect, inView: view, animated: true)
}
else {
// alert displayed when the instagram application is not available in the device
UIAlertView(title: kAlertViewTitle, message: kAlertViewMessage, delegate:nil, cancelButtonTitle:"Ok").show()
}
}
}
func sendToInstagram(){
let image = postImage
InstagramManager.sharedManager.postImageToInstagramWithCaption(image!, instagramCaption: "\(description)", view: self.view)
}
UIDocumentInteractionControllerを使用せずにこれを実行し、次の3つの方法でInstagramに直接アクセスできます。
他の有名なアプリと同じように機能します。コードはObjective Cで記述されているため、必要に応じてSwiftに変換できます。あなたがする必要があるのは、デバイスに画像を保存し、URLSchemeを使用することです
これを.mファイル内に追加します
#import <Photos/Photos.h>
最初に、このメソッドを使用してUIImageをデバイスに保存する必要があります。
-(void)savePostsPhotoBeforeSharing
{
UIImageWriteToSavedPhotosAlbum([UIImage imageNamed:@"image_file_name.jpg"], self, @selector(image:didFinishSavingWithError:contextInfo:), NULL);
}
このメソッドは、デバイスに画像を保存するためのコールバックです：
- (void)image:(UIImage *)image didFinishSavingWithError:(NSError *)error contextInfo: (void *) contextInfo;
{
[self sharePostOnInstagram];
}
画像がデバイスに保存された後、保存したばかりの画像を照会し、PHAssetとして取得する必要があります
-(void)sharePostOnInstagram
{
PHFetchOptions *fetchOptions = [PHFetchOptions new];
fetchOptions.sortDescriptors = @[[NSSortDescriptor sortDescriptorWithKey:@"creationDate" ascending:NO],];
__block PHAsset *assetToShare;
PHFetchResult *result = [PHAsset fetchAssetsWithMediaType:PHAssetMediaTypeImage options:fetchOptions];
[result enumerateObjectsUsingBlock:^(PHAsset *asset, NSUInteger idx, BOOL *stop) {
assetToShare = asset;
}];
if([assetToShare isKindOfClass:[PHAsset class]])
{
NSString *localIdentifier = assetToShare.localIdentifier;
NSString *urlString = [NSString stringWithFormat:@"instagram://library?LocalIdentifier=%@",localIdentifier];
NSURL *instagramURL = [NSURL URLWithString:urlString];
if ([[UIApplication sharedApplication] canOpenURL: instagramURL])
{
[[UIApplication sharedApplication] openURL: instagramURL];
} else
{
// can not share with whats app
NSLog(@"No instagram installed");
}
}
}
そして、これをinfo.plistのLSApplicationQueriesSchemesの下に置くことを忘れないでください
<string>instagram</string>
正解は次のとおりです。 Instagramに画像を直接投稿することはできません。 UIDocumentInteractionControllerを使用してInstagramにリダイレクトする必要があります...
NSString* imagePath = [NSString stringWithFormat:@"%@/instagramShare.igo", [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) lastObject]];
[[NSFileManager defaultManager] removeItemAtPath:imagePath error:nil];
UIImage *instagramImage = [UIImage imageNamed:@"imagename you want to share"];
[UIImagePNGRepresentation(instagramImage) writeToFile:imagePath atomically:YES];
NSLog(@"Image Size >>> %@", NSStringFromCGSize(instagramImage.size));
self.dic=[UIDocumentInteractionController interactionControllerWithURL:[NSURL fileURLWithPath:imagePath]];
self.dic.delegate = self;
self.dic.UTI = @"com.instagram.exclusivegram";
[self.dic presentOpenInMenuFromRect: self.view.frame inView:self.view animated:YES ];
}
注： instagramアプリにリダイレクトすると、アプリに戻ることはできません。アプリをもう一度開く必要があります
- (void) shareImageWithInstagram
{
NSURL *instagramURL = [NSURL URLWithString:@"instagram://"];
if ([[UIApplication sharedApplication] canOpenURL:instagramURL])
{
UICachedFileMgr* mgr = _gCachedManger;
UIImage* photoImage = [mgr imageWithUrl:_imageView.image];
NSData* imageData = UIImagePNGRepresentation(photoImage);
NSString* captionString = [NSString stringWithFormat:@"ANY_TAG",];
NSString* imagePath = [UIUtils documentDirectoryWithSubpath:@"image.igo"];
[imageData writeToFile:imagePath atomically:NO];
NSURL* fileURL = [NSURL fileURLWithPath:[NSString stringWithFormat:@"file://%@",imagePath]];
self.docFile = [[self setupControllerWithURL:fileURL usingDelegate:self]retain];
self.docFile.annotation = [NSDictionary dictionaryWithObject: captionString
forKey:@"InstagramCaption"];
self.docFile.UTI = @"com.instagram.photo";
// OPEN THE HOOK
[self.docFile presentOpenInMenuFromRect:self.view.frame inView:self.view animated:YES];
}
else
{
[UIUtils messageAlert:@"Instagram not installed in this device!\nTo share image please install instagram." title:nil delegate:nil];
}
}
私は自分のアプリケーションでこれを試しましたが、間違いなく動作します
@import Photos;
-(void)shareOnInstagram:(UIImage*)imageInstagram {
[self authorizePHAssest:imageInstagram];
}
-(void)authorizePHAssest:(UIImage *)aImage{
PHAuthorizationStatus status = [PHPhotoLibrary authorizationStatus];
if (status == PHAuthorizationStatusAuthorized) {
// Access has been granted.
[self savePostsPhotoBeforeSharing:aImage];
}
else if (status == PHAuthorizationStatusDenied) {
// Access has been denied.
}
else if (status == PHAuthorizationStatusNotDetermined) {
// Access has not been determined.
[PHPhotoLibrary requestAuthorization:^(PHAuthorizationStatus status) {
if (status == PHAuthorizationStatusAuthorized) {
// Access has been granted.
[self savePostsPhotoBeforeSharing:aImage];
}
}];
}
else if (status == PHAuthorizationStatusRestricted) {
// Restricted access - normally won't happen.
}
}
-(void)saveImageInDeviceBeforeSharing:(UIImage *)aImage
{
UIImageWriteToSavedPhotosAlbum(aImage, self, @selector(image:didFinishSavingWithError:contextInfo:), NULL);
}
- (void)image:(UIImage *)image didFinishSavingWithError:(NSError *)error contextInfo: (void *) contextInfo;
{
if (error == nil){
[self sharePostOnInstagram];
}
}
-(void)shareImageOnInstagram
{
PHFetchOptions *fetchOptions = [PHFetchOptions new];
fetchOptions.sortDescriptors = @[[NSSortDescriptor sortDescriptorWithKey:@"creationDate" ascending:false]];
PHFetchResult *result = [PHAsset fetchAssetsWithMediaType:PHAssetMediaTypeImage options:fetchOptions];
__block PHAsset *assetToShare = [result firstObject];
if([assetToShare isKindOfClass:[PHAsset class]])
{
NSString *localIdentifier = assetToShare.localIdentifier;
NSString *urlString = [NSString stringWithFormat:@"instagram://library?LocalIdentifier=%@",localIdentifier];
NSURL *instagramURL = [NSURL URLWithString:urlString];
if ([[UIApplication sharedApplication] canOpenURL: instagramURL])
{
[[UIApplication sharedApplication] openURL:instagramURL options:@{} completionHandler:nil];
} else
{
NSLog(@"No instagram installed");
}
}
}
注：-IMP TODO：-Info.plistに以下のキーを追加
<key>LSApplicationQueriesSchemes</key>
<array>
<string>instagram</string>
</array>
私に関しては、ここで説明する最良かつ最も簡単な方法 iOSアプリからInstagramに写真を共有する
.igo形式を使用してデバイスに画像を保存し、「UIDocumentInteractionController」を使用してローカルパスInstagramアプリを送信する必要があります。 「UIDocumentInteractionControllerDelegate」を設定することを忘れないでください
私のアドバイスは次のようなものを追加することです：
NSURL *instagramURL = [NSURL URLWithString:@"instagram://app"];
if ([[UIApplication sharedApplication] canOpenURL:instagramURL])
{
<your code>
}
NSURL *instagramURL = [NSURL URLWithString:@"instagram://app"];
if ([[UIApplication sharedApplication] canOpenURL:instagramURL])
{
NSString *jpgPath = [NSHomeDirectory() stringByAppendingPathComponent:[NSString stringWithFormat:@"Documents/Insta_Images/%@",@"shareImage.png"]];
NSURL *igImageHookFile = [[NSURL alloc] initWithString:[[NSString alloc] initWithFormat:@"file://%@", jpgPath]];
docController.UTI = @"com.instagram.photo";
docController = [self setupControllerWithURL:igImageHookFile usingDelegate:self];
docController =[UIDocumentInteractionController interactionControllerWithURL:igImageHookFile];
docController.delegate=self;
[docController presentOpenInMenuFromRect:CGRectMake(0 ,0 , 612, 612) inView:self.view animated:YES];
URLに画像を指すactivityItemsをUIImageの代わりに配置すると、Copy to Instagramアクティビティアイテム自体が表示され、他に何もする必要はありません。 String内のactivityItemsオブジェクトは破棄され、Instagramにキャプションを事前に入力する方法がないことに注意してください。それでもユーザーに特定のキャプションを投稿するように勧めたい場合は、そのテキストをクリップボードにコピーし、ユーザーにそれを知らせるカスタムアクティビティを作成する必要があります this Gist のように。
-(void)shareOnInstagram {
CGRect rect = CGRectMake(self.view.frame.size.width*0.375 ,self.view.frame.size.height/2 , 0, 0);
NSString * saveImagePath = [NSHomeDirectory() stringByAppendingPathComponent:@"Documents/ShareInstragramImage.igo"];
[UIImagePNGRepresentation(_image) writeToFile:saveImagePath atomically:YES];
NSURL *igImageHookFile = [[NSURL alloc] initWithString:[[NSString alloc] initWithFormat:@"file://%@", saveImagePath]];
self.documentController=[UIDocumentInteractionController interactionControllerWithURL:igImageHookFile];
self.documentController.UTI = @"com.instagram.exclusivegram";
self.documentController = [self setupControllerWithURL:igImageHookFile usingDelegate:self];
[self.documentController presentOpenInMenuFromRect: rect inView: self.view animated: YES ];
}
-(UIDocumentInteractionController *) setupControllerWithURL: (NSURL*) fileURL usingDelegate: (id <UIDocumentInteractionControllerDelegate>) interactionDelegate {
UIDocumentInteractionController *interactionController = [UIDocumentInteractionController interactionControllerWithURL: fileURL];
interactionController.delegate = interactionDelegate;
return interactionController;
}
私はこのコードを使用しました：
NSString* filePathStr = [[NSBundle mainBundle] pathForResource:@"UMS_social_demo" ofType:@"png"];
NSURL* fileUrl = [NSURL fileURLWithPath:filePathStr];
NSString *jpgPath = [NSHomeDirectory() stringByAppendingPathComponent:@"Documents/test.igo"];
[[NSData dataWithContentsOfURL:fileUrl] writeToFile:jpgPath atomically:YES];
NSURL* documentURL = [NSURL URLWithString:[NSString stringWithFormat:@"file://%@", jpgPath]];
UIDocumentInteractionController *interactionController = [UIDocumentInteractionController interactionControllerWithURL: documentURL];
self.interactionController = interactionController;
interactionController.delegate = self;
interactionController.UTI = @"com.instagram.photo";
CGRect rect = CGRectMake(0 ,0 , 0, 0);
[interactionController presentOpenInMenuFromRect:rect inView:self.view animated:YES];
