FacebookでTheta 360度の写真を投稿する方法

Question

Theta Camera SDKを使用して360度の画像を撮影しています。

私はこの写真をFacebookに投稿します。これは360 photoです。

あなたが要求してきたと仮定すると：

  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"); 

       } 
      }];

 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"); 

       } 
      }];

360視野に入れ、通常の画像のようなポストではなかったです共有する権限がある場合は、これを使用します。

[[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); 
            } 
            }];
