Question

For the new Facebook SDK 4.x (4.1) for iOS had new changes with the frameworks . It includes 3 different framework as like
Core
Sharing
Login.
To share any image I used FBSDKSharePhoto Class. But it has method
[FBSDKSharePhoto photoWithImage:(*UIImage) userGenerated:(BOOL)]
I want to add caption with the image as string and text. can Anyone help me for this so I can post caption with the image using FB's new sdk.
Thanks in Advance.

Answer 1

As #NANNAV posted it will work, but if you want to share silently with out any FB Dialog screen then use "shareWithContent" as below, but you need to submit your Facebook app for review.
Code in Obj-c
FBSDKSharePhoto *sharePhoto = [[FBSDKSharePhoto alloc] init];
sharePhoto.caption = #"Test Caption";
sharePhoto.image = [UIImage imageNamed:#"BGI.jpg"];
FBSDKSharePhotoContent *content = [[FBSDKSharePhotoContent alloc] init];
content.photos = #[sharePhoto];
[FBSDKShareAPI shareWithContent:content delegate:self];
Code in Swift
var sharePhoto = FBSDKSharePhoto()
sharePhoto.caption = "Test"
sharePhoto.image = UIImage(named: "BGI.jpg")
var content = FBSDKSharePhotoContent()
content.photos = [sharePhoto]
FBSDKShareAPI.shareWithContent(content, delegate: self)

Answer 2

Assign your Caption String to caption Key value
#property (nonatomic, copy) NSString *caption;
Try This :
FBSDKSharePhoto *photo = [[FBSDKSharePhoto alloc] init];
photo.image = image;
photo.userGenerated = YES;
photo.caption = #"Add Your caption";
FBSDKSharePhotoContent *content = [[FBSDKSharePhotoContent alloc] init];
content.photos = #[photo];
[FBSDKShareDialog showFromViewController:self
withContent:content
delegate:nil];

Add the below code to share text to facebook using Facebook SDK 4.x
FBSDKGraphRequestConnection *connection =[[FBSDKGraphRequestConnection alloc]init];
NSMutableDictionary *params = [NSMutableDictionary dictionaryWithObjectsAndKeys:#"Your_message_here_to_share_FB", #"message",
nil];
FBSDKGraphRequest *request = [[FBSDKGraphRequest alloc] initWithGraphPath:#"me/feed" parameters:params HTTPMethod:#"POST"];
[connection addRequest:request completionHandler:^(FBSDKGraphRequestConnection *connection, id result, NSError *error) {
if(error){
NSLog(#"Failed to share");
}
else{
NSLog(#"Updated successfully");
}
}];
*Add below code to share photo.
FBSDKGraphRequestConnection *connection =[[FBSDKGraphRequestConnection alloc]init];
NSMutableDictionary *params = [NSMutableDictionary dictionaryWithObjectsAndKeys: image, #"picture",
#"Your_text_here",#"message",
nil];
FBSDKGraphRequest *request = [[FBSDKGraphRequest alloc] initWithGraphPath:#"me/photos" parameters:params HTTPMethod:#"POST"];
[connection addRequest:request completionHandler:^(FBSDKGraphRequestConnection *connection, id result, NSError *error) {
if(result)
{
NSLog(#"Posting the image is success, the result is%#",result);
}
else if(error)
{
NSLog(#"Error occured while posting image %#",error);
}
}];
[connection start];
