如何使用圖形API將圖像和文本一起發佈？

Question

下面的代碼successfuly後我在Facebook上牆上的文字，現在我想用下面的代碼

- (IBAction)callFacebookAPI:(id)sender 
{ 
[self.txtinputfield resignFirstResponder]; 
if (txtinputfield.text.length !=0) 
{ 
    //create the instance of graph api 
    objFBGraph = [[FbGraph alloc]initWithFbClientID:FbClientID]; 

    //mark some permissions for your access token so that it knows what permissions it has 

    [objFBGraph authenticateUserWithCallbackObject:self andSelector:@selector(FBGraphResponse) andExtendedPermissions:@"user_photos,user_videos,publish_stream,offline_access,user_checkins,friends_checkins,publish_checkins,email"]; 
} 
else 
{ 
    UIAlertView *objAlert = [[UIAlertView alloc]initWithTitle:@"Alert" message:@"Kindly enter data in the text field" delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil]; 
    [objAlert show]; 
} 
} 

- (void)FBGraphResponse 
{ 

@try 
{ 
    if (objFBGraph.accessToken) 
    { 
     SBJSON *jsonparser = [[SBJSON alloc]init]; 

     FbGraphResponse *fb_graph_response = [objFBGraph doGraphGet:@"me" withGetVars:nil]; 

     NSString *resultString = [NSString stringWithString:fb_graph_response.htmlResponse]; 
     NSDictionary *dict = [jsonparser objectWithString:resultString]; 
     NSLog(@"Dict = %@",dict); 

     NSMutableDictionary *variable = [[NSMutableDictionary alloc]initWithCapacity:1]; 

     [variable setObject:txtinputfield.text forKey:@"message"]; 
     [objFBGraph doGraphPost:@"me/feed" withPostVars:variable]; 

     UIAlertView *objAlert = [[UIAlertView alloc]initWithTitle:@"Alert" message:@"String posted on your wall and you may check the console now" delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil]; 
     [objAlert show]; 


    } 
} 
@catch (NSException *exception) { 
    UIAlertView *objALert = [[UIAlertView alloc]initWithTitle:@"Alert" message:[NSString stringWithFormat:@"Something bad happened due to %@",[exception reason]] delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil]; 
    [objALert show]; 
} 

txtinputfield.text = clearText; 
}

嘗試象下面這樣：

- (IBAction)buttonClicked:(id)sender 
{ 
    NSArray* permissions = [[NSArray alloc] initWithObjects: 
          @"publish_stream", nil]; 
    [facebook authorize:permissions delegate:self]; 
    [permissions release]; 

} 
- (void)fbDidLogin 
{ 
    NSString *filePath =pathToImage; 
     NSData *videoData = [NSData dataWithContentsOfFile:filePath]; 
     NSMutableDictionary *params = [NSMutableDictionary dictionaryWithObjectsAndKeys: 
            videoData, pathToImage, 
            @"picture/jpeg", @"contentType", 
            @"Video Test Title", @"title", 
            @"Video Test Description", @"description", 
            nil]; 
    [facebook requestWithGraphPath:@"me/photos" 
         andParams:params 
        andHttpMethod:@"POST" 
         andDelegate:self]; 
    } 
-(void)fbDidNotLogin:(BOOL)cancelled 
{ 
    NSLog(@"did not login"); 
} 
- (void)request:(FBRequest *)request didLoad:(id)result 
{ 
    if ([result isKindOfClass:[NSArray class]]) 
    { 
     result = [result objectAtIndex:0]; 
    } 
    NSLog(@"Result of API call: %@", result); 
} 
- (void)request:(FBRequest *)request didFailWithError:(NSError *)error 
{ 
    NSLog(@"Failed with error: %@", [error localizedDescription]); 
}
