在iphone的facebook牆上分享圖片和文字不起作用？

Question

你好伙計們，我想直接在iphone上分享圖片並分享文字。 我在按鈕點擊時實現了以下代碼，但它什么也沒做......

     NSMutableDictionary *variables = [NSMutableDictionary dictionaryWithCapacity:4];

 [variables setObject:[NSString stringWithFormat:@"Hi... Testing APp"] forKey:@"message"];
 [variables setObject:@"http://icon.png" forKey:@"picture"];       //http://tinyurl.com/45xy4kw
 [variables setObject:@"Create post" forKey:@"name"];
 [variables setObject:@"Write description." forKey:@"description"];

 [facebook requestWithGraphPath:@"/me/feed" andParams:variables andHttpMethod:@"POST" andDelegate:self]; 

我正在使用Facebook直接api這個Facebook API

使用此代碼工作正常

-(IBAction)postMeFeedButtonPressed:(id)sender {

    NSMutableDictionary *variables = [NSMutableDictionary dictionaryWithCapacity:8];


    //create a UIImage (you could use the picture album or camera too)
    UIImage *picture = [UIImage imageNamed:@"Icon@2x.png"];

    //create a FbGraphFile object insance and set the picture we wish to publish on it
    FbGraphFile *graph_file = [[FbGraphFile alloc] initWithImage:picture];

    //finally, set the FbGraphFileobject onto our variables dictionary....
    [variables setObject:graph_file forKey:@"file"];

    NSArray *idarry=[[NSArray alloc]initWithArray:Delegate.IdListArray];
    NSLog(@"Delegate array %@",Delegate.IdListArray);

    //NSString *str=[NSString stringWithFormat:@"100001912715296,100001912715296"];
    NSString *str=[idarry componentsJoinedByString:@","];

    NSLog(@"The string contents are %@",str);

   NSString *idstr=[NSString stringWithFormat:@"100002875785051,100001912715296"];

    [variables setObject:idstr forKey:@"tags"];
    [variables setObject:@"110506962309835" forKey:@"place"];

    [variables setObject:@"Hello All my dear friends,I am using MySafety APP" forKey:@"message"];
    [variables setObject:@"http://techilasolutions.com/product.html" forKey:@"link"];
    [variables setObject:@"My Safety" forKey:@"name"];
    [variables setObject:@"http://techilasolutions.com/images/car_tag.png" forKey:@"picture"];
    [variables setObject:@"This is a must have app for all women whether you are a working lady, a house wife or a school going girl.This app lets you save 6 emergency contacts whom you want to alert in case of emergency.Whenever you feel you are in danger, just press the SOS button and it will send sms to your contacts with your current location and a alarm will go on with flashing lights" forKey:@"description"];

    FbGraphResponse *fb_graph_response = [fbGraph doGraphPost:@"me/feed" withPostVars:variables];
    NSLog(@"postMeFeedButtonPressed:  %@", fb_graph_response.htmlResponse);

    //parse our json
    SBJSON *parser = [[SBJSON alloc] init];
    NSDictionary *facebook_response = [parser objectWithString:fb_graph_response.htmlResponse error:nil];
    [parser release];

    //let's save the 'id' Facebook gives us so we can delete it if the user presses the 'delete /me/feed button'
    self.feedPostId = (NSString *)[facebook_response objectForKey:@"id"];
    NSLog(@"feedPostId, %@", feedPostId);
    NSLog(@"Now log into Facebook and look at your profile...");

}

您可以使用此代碼發布圖像嘗試此代碼一次。

-(IBAction)postPictureButtonPressed:(id)sender 
  {
     NSMutableDictionary *variables = [NSMutableDictionary dictionaryWithCapacity:2];

     UIImage *picture = [UIImage imageNamed:@"75x75.png"];

     FbGraphFile *graph_file = [[FbGraphFile alloc] initWithImage:picture];

     [variables setObject:graph_file forKey:@"file"];

     [variables setObject:@"this is a test message: postPictureButtonPressed" forKey:@"message"];

     FbGraphResponse *fb_graph_response = [fbGraph doGraphPost:@"117795728310/photos" withPostVars:variables];
     NSLog(@"postPictureButtonPressed:  %@", fb_graph_response.htmlResponse);

     NSLog(@"Now log into Facebook and look at your profile & photo albums...");

   }
