Iphone 在iPad中将图像发布到Facebook时出现问题

我正在开发iPad应用程序。我想在Facebbok上发布一张图片。我使用了与iPhone相同的整合facebook的过程。 我的问题是，这张图片并没有发布到facebook上，但在iPhone上它可以正常工作

Code:


  // code to post image to facebook
   //update user facebook status
 -(void)setUsersStatus:(UIImage *)crtImage
  { 

   UIGraphicsBeginImageContext(CGSizeMake(480.0,320.0));


   // Draw the original image
   [crtImage drawInRect:CGRectMake(0,0,480,320)];



   UIImage *newImage = UIGraphicsGetImageFromCurrentImageContext();
   UIGraphicsEndImageContext();

   NSMutableDictionary *args = [[[NSMutableDictionary alloc] init] autorelease];
  [args setObject:@"caption" forKey:@"caption"];      
  FBRequest *uploadPhotoRequest = [FBRequest requestWithDelegate:self];
  NSData *data = UIImagePNGRepresentation(newImage);



   [uploadPhotoRequest call:@"photos.upload" params:args dataParam:data];

  }





  // used to post image to facebook

  -(void)sentAction:(id)sender
   {
   IpadComicBuilderAppDelegate* appDelegate =(IpadComicBuilderAppDelegate*) [  [UIApplication sharedApplication] delegate];

    [appDelegate.facebookObject tryToUpdateStatus:fbImage];
    [self.navigationController dismissModalViewControllerAnimated:YES];
    }

有谁能帮我在iPad上把图片上传到FB上吗

提前感谢。

假设您正在使用最新的Facebook iOS SDK，并且您已经声明了名为

Facebook

的

Facebook

类的实例：

首先检查权限

- (void)setupFacebook
{
    NSString *accessToken = [[NSUserDefaults standardUserDefaults] stringForKey:@"FBAccessToken"];
    NSDate *tokenExpiryDate = [[NSUserDefaults standardUserDefaults] objectForKey:@"FBExpirationDate"];
    facebook.accessToken = accessToken;
    facebook.expirationDate = tokenExpiryDate;
    if ([facebook isSessionValid] == NO) 
    {
        NSLog(@"Not logged in yet. Let's do it!");
        NSArray *permissions = [NSArray arrayWithObjects:@"read_stream", @"offline_access", @"publish_stream", nil];
        [facebook authorize:permissions delegate:self];
    } else {
        NSLog (@"Already logged in and ready to roll.");
        [self uploadPhoto]
    }
}

通过下面的委托方法可以获得对身份验证请求的响应。在这里，您可以将accessToken和tokenExpiryDate保存到NSUserDefaults中，以便保存登录凭据

-(void)fbDidLogin 
-(void)fbDidNotLogin:(BOOL)cancelled 

一旦您登录并拥有正确的权限，就可以调用此方法

- (void)uploadPhoto
{
    UIImage *image = // Your image here
    NSString *graphPath = @"me/photos";
    NSMutableDictionary *params = [NSMutableDictionary dictionaryWithObjectsAndKeys:image, @"picture", "Test caption", "caption"];
    [facebook requestWithGraphPath:graphPath andParams:params andHttpMethod:@"POST" andDelegate:self];
}

上传呼叫的响应将通过以下代理方法提供：

- (void)request:(FBRequest *)request bodyDataUploadProgress:(CGFloat)progress
- (void)request:(FBRequest *)request didLoad:(id)result
- (void)request:(FBRequest *)request didFailWithError:(NSError *)error

希望有帮助。
