與facebook共享內容sdk 4.0 + iOS

Question

我使用iOS上的Facebook SDK（objective-c）在Facebook上共享圖像。下面是我使用的代碼：

-(IBAction)facebookShare:(UIButton *)sender { 
FBSDKSharePhoto *photo = [[FBSDKSharePhoto alloc] init]; 
photo.image = self.image; 
photo.userGenerated = YES; 
FBSDKSharePhotoContent *content = [[FBSDKSharePhotoContent alloc] init]; 
content.photos = @[photo]; 
[FBSDKShareDialog showFromViewController:self withContent:content delegate:self]; 
} 

如果圖像是由我從用戶的畫廊拿起它設置一個UIImage的。當我嘗試按我的按鈕（這個IBAction爲）應用程序崩潰給這個錯誤：

7月1日十點50分23秒。當地PKD [917]：對於PID 922 7月1日10:50錯誤檢索的權利： 23 - [MainViewController sharer：didFailWithError：]：無法識別的選擇器發送到實例0x7fd70940efd0 Jul 1 10:50:23：***終止應用程序由於未捕獲的異常'NSInvalidArgumentException'，原因：' - [MainViewController sharer：didFailWithError：]：無法識別的選擇發送到實例0x7fd70940efd0'

這裏是新的錯誤以這種方式固定碼後

FBSDKSharePhoto *photo = [[FBSDKSharePhoto alloc] init]; 
     photo.image = //YOUR IMAGE                 photo.userGenerated = YES; 
     FBSDKSharePhotoContent * photoContent = [[FBSDKSharePhotoContent alloc] init]; 
     photoContent.photos = @[photo]; 
     FBSDKShareDialog *shareDialog = [[FBSDKShareDialog alloc] init]; 
     shareDialog.shareContent = photoContent; 
     shareDialog.delegate = (id)self; 
     shareDialog.fromViewController = self; 
     NSError * error = nil; 
     BOOL validation = [shareDialog validateWithError:&error]; 
     if (validation) { 
      [shareDialog show]; 
     }

使用不同的仿真器終於解決。

在早期版本的FB SDK中存在一個錯誤，但在這裏似乎缺少必需的委託方法實現。

 FBSDKSharePhoto *photo = [[FBSDKSharePhoto alloc] init]; 
     photo.image = //YOUR IMAGE                 photo.userGenerated = YES; 
     FBSDKSharePhotoContent * photoContent = [[FBSDKSharePhotoContent alloc] init]; 
     photoContent.photos = @[photo]; 
     FBSDKShareDialog *shareDialog = [[FBSDKShareDialog alloc] init]; 
     shareDialog.shareContent = photoContent; 
     shareDialog.delegate = (id)self; 
     shareDialog.fromViewController = self; 
     NSError * error = nil; 
     BOOL validation = [shareDialog validateWithError:&error]; 
     if (validation) { 
      [shareDialog show]; 
     } 

並實施所需的代表方法

- (void)sharer:(id<FBSDKSharing>)sharer didCompleteWithResults:(NSDictionary *)results { 
    // handle 
} 
- (void)sharer:(id<FBSDKSharing>)sharer didFailWithError:(NSError *)error{ 
    // handle 
} 
- (void)sharerDidCancel:(id<FBSDKSharing>)sharer{ 
    // handle 
}
