Post photo in facebook on the friends gallery for ios -

-

Good morning,

I have this code to post a photo to my gallery: 

  - (IBAction) postPhotoClick: (UIButton *) Sender {// Just use the icon image from the app. A real application would be a more useful way to get the image. UIImage * img = [UIImage imageNamed: @ "Icon-72@2x.png"]; // if it is available to us, we will post using the native dialog BOOL displayNativeDialog = [FBNativeDialogs presentShareDialogModallyFrom: own initial text: no image: IMG URL: void handler: nil]; (! DisplayedNativeDialog) if {[self performPublishAction: ^ {[FBRequestConnection startForUploadPhoto: img completionHandler: ^ (FBRequestConnection * connection, ID results, NSError * error) {[self showAlert: @ "post photos" Results: Results Error: error]; Self.buttonPostPhoto.enabled = Yes; }]; Self.buttonPostPhoto.enabled = No; // proceedToPost (); }]; }}   
 However, I need to post photos to my friends' gallery. it's possible? How can I go about doing this?   
 
 
 I've found solutions using the graphing API.  
 After proper login:  
  NSMutableDictionary * parameter = [NSMutableDictionary dictionaryWithObjectsAndKeys: self.originalImage, @ "source", @ "MessageText", @ "message" Zero]; [Self.facebook requestWithGraphPath: @ "user_name / photos /" and Param: Params and Acteepim method: @ "Post" and Dielit: self];   
 This code works to post an image in my albuns. Now I need to post a picture on my friends' album.

After opening several examples of macro / code written, I suddenly get stuck with a code that seems safe. Solver (SOLVER.XLAM) is doing this notation and I would like to remove it from my system. I do not think this is a relativant code. Can anyone tell me what should I do? I have already installed something to remove the password but Solver is still asking for password and I can not get rid of it! itemprop = "text"> Solver Excel is add-in If you want to delete it, then Excel Application & gt; Options & gt; Add-ins & gt; Search for 'Go to' button and gt; Uncheck the solver on the list like press something (I can not give you the exact path because I have the Polish version of Excel). Trying to open Solver's VBA code is not good because it There is allegedly copyright. Besides, I do not think Solver creates any disadvantages while working with Excel or VBA.

github - Teamcity & Git - PR merge builds - anyway to get HEAD commit hash? -

-
I have a team city build project with Gitbab VCS route, I have been triggered for both / head on PR and / Merge the referee. The annoying thing is that you can not do anything useful with the merged hash - it is not present in Gitobb. I want to exclude newsgate packages with head in gutub comet situations in the version number along with Hewash (Newsaging 7) for the music build, but against head hash. However, I can not see a way to get the head hashes while constructing that merge. I just want to head because it's useless - we only care about merge. (PR - Pull Request) This command works reliably while running One on / merge is git log --no-merge -1 ---- = '% h'
