如何在iOS中的Instagram上共享图像？

87

我的客户希望在Instagram，Twitter，Facebook上共享图像。

我已经完成了Twitter和Facebook，但是在互联网上找不到任何API或任何东西可以在Instagram上共享图像。是否可以在Instagram上分享图片？如果是，那怎么办？

当我检查Instagram的开发人员站点时，我发现了Ruby on Rails和Python库。但是没有iOS Sdk的文档

我已经根据instagram.com/developer从instagram获取了令牌，但现在不知道下一步如何与instagram图像共享。

ios  objective-c  swift  share  instagram

终于我得到了答案。您不能直接在instagram上发布图片。您必须使用UIDocumentInteractionController重新整理图像。

@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;
}

注意：重定向到instagram应用后，您将无法返回到您的应用。您必须再次打开您的应用

@SurenderRathore，您必须将图像缩放到612 * 612并保存为.ig格式。ig显示要在instagram中打开图像，并且必须在iPhone或iPod最高版本4.3中进行测试。不支持iPad

@HiRen：是的，您是对的，但是在我的应用程序中，我正在拍摄视图的屏幕截图，然后通过instagram应用程序共享该屏幕截图，并且效果很好。但我也想通过该屏幕截图传递一些静态文本。如果您有任何想法请帮助我。github上有一个用于DMACtivityInstagram的演示代码，您可以从那里看到我想说的话。提前致谢。

使用此行使我在iOS 6中崩溃：NSURL * igImageHookFile = [[NSURL alloc] initWithString：[[NSString alloc] initWithFormat：@“ file：//％@”，jpgPath]]; 两者均可使用：NSURL * igImageHookFile = [NSURL fileURLWithPath：jpgPath]; 除非我丢失了某些内容，否则可能值得相应地编辑答案？

您可以使用Instagram提供的网址方案之一

在此处输入图片说明

  1. Instagram官方文档在这里

  2. 与UIDocumentInteractionController共享

    final class InstagramPublisher : NSObject {

private var documentsController:UIDocumentInteractionController = UIDocumentInteractionController()

func postImage(image: UIImage, view: UIView, result:((Bool)->Void)? = nil) {
    guard let instagramURL = NSURL(string: "instagram://app") else {
        if let result = result {
            result(false)
        }
    return
}
    if UIApplication.sharedApplication().canOpenURL(instagramURL) {
        let jpgPath = (NSTemporaryDirectory() as NSString).stringByAppendingPathComponent("instagrammFotoToShareName.igo")
        if let image = UIImageJPEGRepresentation(image, 1.0) {
            image.writeToFile(jpgPath, atomically: true)
            let fileURL = NSURL.fileURLWithPath(jpgPath)
            documentsController.URL = fileURL
            documentsController.UTI = "com.instagram.exclusivegram"
            documentsController.presentOpenInMenuFromRect(view.bounds, inView: view, animated: true)
            if let result = result {
                result(true)
            }
        } else if let result = result {
            result(false)
        }
    } else {
        if let result = result {
            result(false)
        }
    }
    }
}

  3. 直接重定向共享

    import Photos

final class InstagramPublisher : NSObject {

func postImage(image: UIImage, result:((Bool)->Void)? = nil) {
guard let instagramURL = NSURL(string: "instagram://app") else {
    if let result = result {
        result(false)
    }
    return
}

let image = image.scaleImageWithAspectToWidth(640)

do {
    try PHPhotoLibrary.sharedPhotoLibrary().performChangesAndWait {
        let request = PHAssetChangeRequest.creationRequestForAssetFromImage(image)

        let assetID = request.placeholderForCreatedAsset?.localIdentifier ?? ""
        let shareURL = "instagram://library?LocalIdentifier=" + assetID

        if UIApplication.sharedApplication().canOpenURL(instagramURL) {
            if let urlForRedirect = NSURL(string: shareURL) {
                UIApplication.sharedApplication().openURL(urlForRedirect)
            }
        }
    }
} catch {
    if let result = result {
        result(false)
    }
}
}
}

  4. 扩展名以将照片调整为推荐尺寸

    import UIKit

extension UIImage {
    // MARK: - UIImage+Resize

    func scaleImageWithAspectToWidth(toWidth:CGFloat) -> UIImage {
        let oldWidth:CGFloat = size.width
        let scaleFactor:CGFloat = toWidth / oldWidth

        let newHeight = self.size.height * scaleFactor
        let newWidth = oldWidth * scaleFactor;

        UIGraphicsBeginImageContext(CGSizeMake(newWidth, newHeight))
        drawInRect(CGRectMake(0, 0, newWidth, newHeight))
        let newImage = UIGraphicsGetImageFromCurrentImageContext()
        UIGraphicsEndImageContext()
        return newImage
    }
}

  5. 不要忘记在plist中添加所需的方案

  <key>LSApplicationQueriesSchemes</key>
  <array>
       <string>instagram</string> 
  </array>

从其他答案中尝试了一堆其他方法，但只有此方法才有效（至少对于视频而言。“ instagram：// library？LocalIdentifier =“是它的功能。非常感谢！
— Bjorn Roche
具有直接重定向功能的共享（到目前为止，这是IMO最好的解决方案）对我不再起作用-Instagram在库页面上打开，但不会预选图像。您是否知道此URL方案可能会发生什么变化？您是否在iOS上使用最新版本的Instagram遇到类似的故障？

希望这个答案能解决您的查询。这将直接在Instagram中打开库文件夹而不是Camera。

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]) {

如果您不想使用UIDocumentInteractionController 

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)
            }

这是我详细介绍的正确答案。在.h文件中

 UIImageView *imageMain;
 @property (nonatomic, strong) UIDocumentInteractionController *documentController;

in.m文件只写

 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");

 }

当然，您会得到结果。例如，您将在底部看到带有instagram图像的弹出窗口。

我在我的应用程序中尝试过，它运行良好（快速）

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)

 }

这是正确的答案。您不能直接在Instagram上发布图片。您需要使用UIDocumentInteractionController重定向到Instagram ...

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 ];

}

注意：重定向到instagram应用后，您将无法返回到您的应用。您必须再次打开您的应用

您可以在不使用UIDocumentInteractionController的情况下做到这一点，并使用以下3种方法直接进入Instagram：

就像其他所有著名的应用程序一样工作。该代码是用Objective c编写的，因此您可以根据需要将其转换为swift。您需要做的是将图像保存到设备并使用URLScheme

将此添加到您的.m文件中

#import <Photos/Photos.h>

首先，您需要使用以下方法将UIImage保存到设备：

-(void)savePostsPhotoBeforeSharing
{
    UIImageWriteToSavedPhotosAlbum([UIImage imageNamed:@"image_file_name.jpg"], self, @selector(image:didFinishSavingWithError:contextInfo:), NULL);
}

此方法是用于将图像保存到设备的回调：

- (void)image:(UIImage *)image didFinishSavingWithError:(NSError *)error contextInfo: (void *) contextInfo;
{
    [self sharePostOnInstagram];

}

将图像保存到设备后，您需要查询刚刚保存的图像并将其作为PHAsset获取

-(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");
        }

    }
}

并且不要忘记将其放在您的info.plist下 LSApplicationQueriesSchemes

<string>instagram</string>

    }
}

我在我的应用程序中尝试过，它肯定会工作

也许您应该解释UIUtils＆UICachedFileMgr？

UIUtils是我创建的用于管理实用程序方法的类，它是从NSObject派生的。我添加了messageAlert方法来显示警报视图。在上面提供了链接的示例应用程序中，您可以找到UIUtils类。希望您会理解。

对于我来说，这里描述的最好和最简单的方法是从我的iOS应用程序将照片分享到Instagram

您需要使用.igo格式将图像保存在设备上，然后使用“ UIDocumentInteractionController”发送本地路径Instagram应用。不要忘记设置“ UIDocumentInteractionControllerDelegate”

我的建议是添加类似以下内容：

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];

我注意到，如果您将URL图像指向activityItems而不是UIImage，Copy to Instagram活动项会自动出现，并且您无需执行其他任何操作。请注意，String内部的对象activityItems将被丢弃，并且无法在Instagram中预填充字幕。如果仍要提示用户张贴特定标题，则需要创建自定义活动，在该活动中，您可以将该文本复制到剪贴板，并让用户知道，如本要点所示。

我使用以下代码：

    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);
