Question

我正在使用Facebook SDK for iOS实现共享对话框。除了回调之外，一切正常。这是显示对话框的功能：

FBSDKShareLinkContent *content = [[FBSDKShareLinkContent alloc] init];
    content.contentURL = <my content url>;
    content.contentTitle = <my title>;
    content.contentDescription = my description;
    content.imageURL = <my image url>;
    [FBSDKShareDialog showFromViewController:self
                                 withContent:content
                                    delegate:self];

视图控制器实现FBSDKSharingDelegate和三个必需的方法：

- (void)sharer:(id<FBSDKSharing>)sharer didCompleteWithResults:(NSDictionary *)results;

- (void)sharer:(id<FBSDKSharing>)sharer didFailWithError:(NSError *)error;

- (void)sharerDidCancel:(id<FBSDKSharing>)sharer;

基本上我必须检测用户是否按下了取消按钮，因为只有当他们有效地共享内容时我才会给予奖励。问题是即使我按下取消按钮，唯一被调用的回调是：

- (void)sharer:(id<FBSDKSharing>)sharer didCompleteWithResults:(NSDictionary *)results;

而不是

- (void)sharerDidCancel:(id<FBSDKSharing>)sharer;

正如所料。此外，使用iOS8，如果按下取消按钮，变量结果为空，否则它包含post_id，但iOS7不会发生这种情况，结果总是为空。

我做错了什么？我应该做些什么来让 sharerDidCancel 回调正常工作？

感谢您的帮助！

尝试将此输入到您的appdelegate。我可以调用正确的代理，但结果字典仍然是空的，我无法获得post_id。

#import <FBSDKCoreKit/FBSDKCoreKit.h>

- (void)applicationDidBecomeActive:(UIApplication *)application {
  [FBSDKAppEvents activateApp];
}

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
  return [[FBSDKApplicationDelegate sharedInstance] application:application
                              didFinishLaunchingWithOptions:launchOptions];
}

- (BOOL)application:(UIApplication *)application openURL:(NSURL *)url sourceApplication:(NSString *)sourceApplication annotation:(id)annotation {
  return [[FBSDKApplicationDelegate sharedInstance] application:application
                                                    openURL:url
                                          sourceApplication:sourceApplication
                                                 annotation:annotation];
}
