How to export an image from our app to Instagram?
I used the following code but it didn't work. I want to put an image from my app into the Instagram app installed on my iPhone.
NSString *fileToOpen = [[NSBundle mainBundle] pathForResource:@"IMG_0192" ofType:@"jpg"];
fileToOpen = [fileToOpen substringToIndex:[fileToOpen length] - 3];
fileToOpen=[NSString stringWithFormat:@"%@ig",fileToOpen];
NSURL *instagramURL = [NSURL URLWithString:@"instagram://app"];
NSLog(@"%@",fileToOpen);
if ([[UIApplication sharedApplication] canOpenURL:instagramURL]) {
//imageToUpload is a file path with .ig file extension
/*UIAlertView *alert = [[UIAlertView alloc]
initWithTitle:@""
message:@"Can open app!"
delegate:self
cancelButtonTitle:@"OK"
otherButtonTitles:nil];
[alert show];
*/
self.documentInteractionController = [UIDocumentInteractionController interactionControllerWithURL:[NSURL fileURLWithPath:fileToOpen]];
self.documentInteractionController.UTI = @"com.instagram.photo";
self.documentInteractionController.annotation = [NSDictionary dictionaryWithObject:@"Its a testing" forKey:@"InstagramCaption"];
I tried a lot but it doesn't work at all.

You can use the following code to share an image from your app in the Instagram app installed on your iPhone.
- (void) shareImageToInstagram
{
NSURL *instagramURL = [NSURL URLWithString:@"instagram://"];
if ([[UIApplication sharedApplication] canOpenURL:instagramURL])
{
CGRect rect = CGRectMake(0,0,0,0);
CGRect cropRect=CGRectMake(0,0,612,612);
NSString *jpgPath=[NSHomeDirectory() stringByAppendingPathComponent:@"Documents/test.igo"];
CGImageRef imageRef = CGImageCreateWithImageInRect([imgViewPost.image CGImage], cropRect);
UIImage *img = [[UIImage alloc] initWithCGImage:imageRef];
CGImageRelease(imageRef);
[UIImageJPEGRepresentation(img, 1.0) writeToFile:jpgPath atomically:YES];
NSURL *igImageHookFile = [[NSURL alloc] initWithString:[[NSString alloc] initWithFormat:@"file://%@",jpgPath]];
self.dicont.UTI = @"com.instagram.photo";
self.dicont = [self setupControllerWithURL:igImageHookFile usingDelegate:self];
self.dicont.annotation = [NSDictionary dictionaryWithObject:@"Your AppName" forKey:@"InstagramCaption"];
[self.dicont presentOpenInMenuFromRect: rect inView: self.view animated: YES ];
}
else
{
DisplayAlert(@"Instagram not installed in this device!\nTo share image please install instagram.");
}
}
- (UIDocumentInteractionController *) setupControllerWithURL: (NSURL*) fileURL usingDelegate: (id <UIDocumentInteractionControllerDelegate>) interactionDelegate {
UIDocumentInteractionController *interactionController = [UIDocumentInteractionController interactionControllerWithURL: fileURL];
interactionController.delegate = interactionDelegate;
return interactionController;
}
Please try this code ..

You can use this code:
-(void)shareImageOnInstagram:(UIImage*)shareImage
{
//It is important that image must be larger than 612x612 size if not resize it.
NSURL *instagramURL = [NSURL URLWithString:@"instagram://app"];
if([[UIApplication sharedApplication] canOpenURL:instagramURL])
{
NSString *documentDirectory=[NSHomeDirectory() stringByAppendingPathComponent:@"Documents"];
NSString *saveImagePath=[documentDirectory stringByAppendingPathComponent:@"Image.ig"];
NSData *imageData=UIImagePNGRepresentation(shareImage);
[imageData writeToFile:saveImagePath atomically:YES];
NSURL *imageURL=[NSURL fileURLWithPath:saveImagePath];
UIDocumentInteractionController *docController=[[UIDocumentInteractionController alloc]init];
docController.delegate=self;
[docController retain];
docController.UTI=@"com.instagram.photo";
docController.annotation=[NSDictionary dictionaryWithObjectsAndKeys:@"Image Taken via @App",@"InstagramCaption", nil];
[docController setURL:imageURL];
[docController presentOpenInMenuFromBarButtonItem:self.navigationItem.rightBarButtonItem animated:YES]; //Here try which one is suitable for u to present the doc Controller. if crash occurs
}
else
{
NSLog ("Instagram is not available");
}
}
