如何发布照片。 iOS Facebook SDK 3.1 [英] How to post a photo. iOS Facebook SDK 3.1

问题描述

我需要在我的墙上发布一张照片。图片是在我的iPad应用程序中生成的。

解决方案

这是我找到的最简单的方法

   - （void）postImageToFB：（UIImage *）image 
 {
 NSData * imageData = UIImageJPEGRepresentation（image，90）; 
 NSMutableDictionary * params = [NSMutableDictionary dictionaryWithObjectsAndKeys：
 @这是我的绘图！，@message，
 imageData，@source，
 nil]; 
 
 [FBRequestConnection startWithGraphPath：@me / photos
参数：params 
 HTTPMethod：@POST
 completionHandler：^（FBRequestConnection * connection，id result， NSError * error）{
 
}]; 
} 
  

如果要在朋友的墙上张贴，请更改 @我/照片 by @[friendID] / photos

然后，请求发布权限并调用方法

  if（[FBSession.activeSession.permissions indexOfObject：@publish_stream ] == NSNotFound）
 {
 //在会话中找不到权限，请求
 [FBSession.activeSession reauthorizeWithPublishPermissions：[NSArray arrayWithObject：@publish_stream] 
 defaultAudience： FBSessionDefaultAudienceFriends 
 completionHandler：^（FBSession * session，NSError * error）
 {
 //如果权限授予，发布故事
 if（！error）[self postImageToFB：currentDrawing] ; 
}]; 
} 
 //如果存在权限，发布故事
 else [self postImageToFB：currentDrawing]; 
  

如果不存在，将创建一个[App Name] Photos相册

它对我有用！

I needed to publish a picture on my wall. The pic is generated in my iPad app.

解决方案

This is the simplest way I've found

- (void) postImageToFB:(UIImage*)image
{
    NSData* imageData = UIImageJPEGRepresentation(image, 90);    
    NSMutableDictionary * params = [NSMutableDictionary dictionaryWithObjectsAndKeys:
                                    @"This is my drawing!", @"message",
                                    imageData, @"source",
                                    nil];

    [FBRequestConnection startWithGraphPath:@"me/photos"
                                 parameters:params
                                 HTTPMethod:@"POST"
                          completionHandler:^(FBRequestConnection *connection, id result, NSError *error) {

                          }];
}

if you want to post on a friend's wall, change @"me/photos" by @"[friendID]/photos"

Then, ask for permissions to publish and call the method

if ([FBSession.activeSession.permissions indexOfObject:@"publish_stream"] == NSNotFound)
{
    // No permissions found in session, ask for it
    [FBSession.activeSession reauthorizeWithPublishPermissions:[NSArray arrayWithObject:@"publish_stream"]
                                               defaultAudience:FBSessionDefaultAudienceFriends
                                             completionHandler:^(FBSession *session, NSError *error)
     {
         // If permissions granted, publish the story
         if (!error) [self postImageToFB:currentDrawing];
     }];
}
// If permissions present, publish the story
else [self postImageToFB:currentDrawing];

An "[App Name] Photos" album will be created, if doesn't exist

It does work for me!
