How to post the Theta 360 degree photo to facebook in ios - ios

Question

I am using the Theta Camera SDK to take the picture in 360 degrees.
I want to post this photo to Facebook this is 360 photo.
UIImage *image = [UIImage imageNamed:#"IMG_0133.JPG"];
NSString *token = [NSString stringWithFormat:#"%#", [FBSDKAccessToken currentAccessToken].tokenString];
NSDictionary *param = #{#"message": #"test",
#"access_token": token,
#"photo":image,
#"allow_spherical_photo": [NSNumber numberWithBool:true]
};
FBSDKGraphRequest *request = [[FBSDKGraphRequest alloc]
initWithGraphPath:#"me/photos"
parameters:param
HTTPMethod:#"post"];
[request startWithCompletionHandler:^(FBSDKGraphRequestConnection *connection,
id result,
NSError *error)
{
if (!error)
{
NSLog(#"post success");
}
}];
but it was post like normal image not with 360 view

UIImage *image = [[UIImage alloc]initWithData:[[NSUserDefaults standardUserDefaults] objectForKey :#"image_NSdata]];
NSData *imgData = UIImageJPEGRepresentation(image, 1);
NSLog(#"Size of Image(bytes):%ld",(unsigned long)[imgData length]);
float actualHeight = image.size.height;
float actualWidth = image.size.width;
NSDictionary * postDictionary = [NSDictionary dictionaryWithObjects:[NSArray arrayWithObjects:#"equirectangular", [NSNumber numberWithFloat:actualWidth] ,[NSNumber numberWithFloat:actualHeight], [NSNumber numberWithFloat:actualWidth] ,[NSNumber numberWithFloat:actualHeight], #"0",#"0", nil]
forKeys:[NSArray arrayWithObjects:#"ProjectionType", #"CroppedAreaImageWidthPixels",#"CroppedAreaImageHeightPixels", #"FullPanoWidthPixels",#"FullPanoHeightPixels", #"CroppedAreaLeftPixels",#"CroppedAreaTopPixels", nil]];
NSError * error = nil;
NSData *jsonData = [NSJSONSerialization dataWithJSONObject:postDictionary options:NSJSONWritingPrettyPrinted error:&error];
NSString *resultAsString = [[NSString alloc] initWithData:jsonData encoding:NSUTF8StringEncoding];
NSLog(#"jsonData as string:\n%# Error:%#", resultAsString,error);
NSString *token = [NSString stringWithFormat:#"%#", [FBSDKAccessToken currentAccessToken].tokenString];
NSDictionary *param = #
{
#"access_token": token,
#"photo":image,
#"allow_spherical_photo": [NSNumber numberWithBool:true],
#"spherical_metadata":resultAsString
};
FBSDKGraphRequest *request = [[FBSDKGraphRequest alloc]
initWithGraphPath:#"me/photos"
parameters:param
HTTPMethod:#"post"];
[request startWithCompletionHandler:^(FBSDKGraphRequestConnection *connection,
id result,
NSError *error)
{
if (!error)
{
NSLog(#"post success");
}
}];

I wrote a framework for this exact purpose:
https://github.com/AppCoders-io/Facebook360
Assuming that you've requested the permission to share, this is what you'd use:
[[Facebook360Manager sharedInstance] shareImage:[UIImage imageNamed:#"spherical360.jpg"]
userCaption:#"Example caption..."
horizontalFOV:360.0
sharePreference:FacebookShareManagerPreferenceSphericalImage
completionBlock:^(NSError * _Nullable error, NSString * _Nullable postID) {
if (error) {
NSLog(#"Error: %#",error);
}else{
NSLog(#"Shared successfully. Post ID: %#",postID);
}
}];
