Facebook 圖 API 上傳圖片問題

Question

I've searched all through the web and have downloaded the Facebook SDK thing to try out the upload photo function and it worked there. 與我的應用程序完全相同的代碼，但它不起作用。 請幫忙？？？ 這些是我的代碼：

- (IBAction)pushUpload:(id)sender {

    NSString *path = @"http://www.facebook.com/images/devsite/iphone_connect_btn.jpg";
    NSURL *url = [NSURL URLWithString:path];
    NSData *data = [NSData dataWithContentsOfURL:url];
    UIImage *img  = [[UIImage alloc] initWithData:data];

    NSMutableDictionary *params = [NSMutableDictionary dictionaryWithObjectsAndKeys:
                                   img, @"picture",
                                   nil];

    [_facebook requestWithGraphPath:@"me/photos"
                          andParams:params
                      andHttpMethod:@"POST"
                        andDelegate:self];

    [img release];

    [loadingIcon startAnimating];
}

如您所見，我已將 loadingIcon 放在那里以在其上傳時開始制作動畫。並且在請求 didload 時，我在成功上傳后執行了 stopanimating 命令。

-(void)request:(FBRequest *)request didLoad:(id)result{

    [loadingIcon stopAnimating];
    if ([result isKindOfClass:[NSArray class]]) {
        result = [result objectAtIndex:0];
    }
    if ([result objectForKey:@"owner"]) {
        [loadingIcon stopAnimating];

        UIAlertView *alert;

        alert = [[UIAlertView alloc] initWithTitle:@"" 
                                           message:@"Photo uploaded." 
                                          delegate:self cancelButtonTitle:@"Ok" 
                                 otherButtonTitles:nil];

        [alert show];
        [alert release];
    } else {
       // [self.label setText:[result objectForKey:@"name"]];
    }
}

問題是，加載圖標只是保持動畫，沒有錯誤，幾乎沒有圖片上傳到我的 facebook 帳戶。 任何想法為什么？

這是 my.h 文件中的代碼：

@interface UploadPhotosViewController: UIViewController(FBRequestDelegate, FBDialogDelegate, FBSessionDelegate){

 IBOutlet UIImageView *imageView; IBOutlet UIActivityIndicatorView *loadingIcon; IBOutlet UIBarButtonItem *_pushPick; IBOutlet UIBarButtonItem *_pushUpload; Facebook * _facebook; }

@property(只讀) Facebook *facebook;

• (IBAction)pushUpload:(id)sender;
• (IBAction)pushPick:(id)sender;

//UINavigationControllerDelegate, UIImagePickerControllerDelegate,

@結尾

另一件需要注意的是，當應該有（FBRequestDelegate，FBDialogDelegate，FBSessionDelegate）時，沒有 colors 指標..這是一個問題嗎？

Answer 1

我認為這是因為您沒有正確聲明您的協議。 他們 go 在尖括號中，而不是在括號中。

@interface UploadPhotosViewController : UIViewController<FBRequestDelegate, FBDialogDelegate, FBSessionDelegate>

檢查您是否在 your.h 文件中寫入了 Facebook 的代表。 還要檢查這個代碼它對我有用..

NSString *string=@"Images of me";
SBJSON *jsonWriter = [[SBJSON new] autorelease];
    NSDictionary* attachment = [NSDictionary dictionaryWithObjectsAndKeys:
                                @"My name", @"name",
                                string, @"description", nil];
    NSString *attachmentStr = [jsonWriter stringWithObject:attachment];



    NSMutableDictionary *params = [NSMutableDictionary dictionaryWithObjectsAndKeys:
                                   @"This is image",@"description",
                                   @"Share on Facebook",  @"user_message_prompt",
                                   //actionLinksStr, @"action_links",
                                   attachmentStr, @"attachment",    
                                  /*Your image here", @"picture",
                                   nil];

試試這個代碼

希望能幫助到你....

試試我/喂而不是我/照片。

[_facebook requestWithGraphPath:@"me/feed"
                      andParams:params
                  andHttpMethod:@"POST"
                    andDelegate:self];
