iOS Facebook SDK 4 FBSDKShareDialog

Question

当我试图通过我的应用程序实现FBSDKShareDialog来实现facebook共享时，我遇到了一些麻烦。如果安装了官方的fb应用程序，它会显示空白对话框(用户允许输入一些文本等)。如果用户没有fb应用程序，它会显示正确的信息，但是FBSDKSharingDelegate方法不起作用。(即使用户有fb应用程序，它也不起作用)

- (void)sharer:(id<FBSDKSharing>)sharer didCompleteWithResults:(NSDictionary *)results
{
    NSLog(@"complete");
}
- (void)sharerDidCancel:(id<FBSDKSharing>)sharer
{
    NSLog(@"did cancel");
}

- (void)sharer:(id<FBSDKSharing>)sharer didFailWithError:(NSError *)error
{
    NSLog(@"%@", error);
}

它从来没有被调用，即使当我取消或分享通过FB申请。我的代码是：

FBSDKShareLinkContent *content = [[FBSDKShareLinkContent alloc] init];
    content.contentTitle = _place.title;
    content.imageURL = [NSURL URLWithString:_place.logoUrl];
    content.contentDescription = _place.info;
[FBSDKShareDialog showFromViewController:_viewController withContent:content delegate:self];

在@interface声明中有一个委托。

@interface FacebookHandler () < FBSDKSharingDelegate >

@end

我的应用程序代表

#import <FBSDKCoreKit/FBSDKCoreKit.h>

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

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

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

我哪里错了？通过FBSDKShareLinkContent发布一些图片和标题是个好主意。提前谢谢。

Answer 1

我已经解决了这个问题。问题是我要委托从NSObject继承的文件，它不能是委托

Answer 2

您是从主线程调用[FBSDKShareAPI shareWithContent:content delegate:self]吗？
