你需要上传图像创建相册，U创造了通过，你必须使用其ID上传照片

// for making a facebook album u have to make a multi-part form request 
//to this url https://graph.facebook.com/100002232753228/albums 
//where 100002232753228 is the fbid of the user and with form fields access_token,name,message, for reference go to -http://developers.facebook.com/docs/reference/api/album/ 

//To upload a foto to album send multi-part data to the url - https://graph.facebook.com/102657189818706/photos 

//where 102657189818706 is the facebook id of the album created 

这里的Facebook API专辑后的代码

#define kRequestBoundary @"----FOO" 

    NSMutableData *postBody = [[NSMutableData alloc] init]; 
    [postBody appendData:[[NSString stringWithFormat:@"--%@\r\n", kRequestBoundary] dataUsingEncoding:NSUTF8StringEncoding]]; //starting the boundary of form data 

         [postBody appendData:[[NSString stringWithFormat:@"Content-Disposition: form-data; name=\"access_token\"\r\n\r\n"] dataUsingEncoding:NSUTF8StringEncoding]]; //setting field name of access_toke 
         [postBody appendData:[[NSString stringWithString:@"200726069952695|fd9c7d8ed4b5592b1240cdb3-100002232753228|i7ae5By6VFItLliVT1jw5jsETEY"] dataUsingEncoding:NSUTF8StringEncoding]]; 
    //setting field value of access_token 

    [postBody appendData:[[NSString stringWithFormat:@"\r\n--%@\r\n", kRequestBoundary] dataUsingEncoding:NSUTF8StringEncoding]]; //closing the boundary for next field

     UIImage *cropped=[UIImage imageNamed:@"Sample.png"]; 



    NSData *pImageData = UIImagePNGRepresentation(cropped); 


    [postBody appendData:pImageData]; // adding image data to the request data

    NSString *urlString = @"https://graph.facebook.com/102657189818706/photos"; 


    NSMutableURLRequest *request=[[NSMutableURLRequest alloc] initWithURL:[NSURL URLWithString:pUrl]]; 
    self.mURLrequest=request; 
    [request release]; 
    [pUrl release]; 
    [request setHTTPMethod:@"POST"]; 

    NSString *contentType = [NSString stringWithFormat:@"multipart/form-data; boundary=%@", kRequestBoundary]; 

    [request setValue:contentType forHTTPHeaderField:@"Content-type"];
