提交指南谈到了“用户生成的照片”权限，该权限似乎在应用程序设置的任何地方或文档中的任何其他地方都不可用。这还需要吗？图片有类似的权限吗？

您可以尝试使用此方法共享带有链接的图像。您要分享的图片需要在服务器上（即您需要使用图片的链接） 注意：- 您必须拥有来自 facebook 应用程序的“publish_actions”权限

以下方法使用 facebook sdk 4.3 显示

在 .h 文件中

#import <FacebookSDK/FacebookSDK.h>
@property (strong, nonatomic) FBRequestConnection *requestConnection;

在 .m 文件中

-(IBAction)facebookBtn:(id)sender{
    if (!FBSession.activeSession.isOpen) {
    // if the session is closed, then we open it here, and establish a handler for state changes
    [FBSession openActiveSessionWithReadPermissions:@[@"public_profile", @"email", @"user_events", @"user_location", @"publish_actions"]
                                       allowLoginUI:YES
                                  completionHandler:^(FBSession *session,
                                                      FBSessionState state,
                                                      NSError *error) {
                                if (error)
                                {
                                    UIAlertView *alertView = [[UIAlertView alloc]initWithTitle:NSLocalizedString(@"Error", nil) message:error.localizedDescription delegate:nil cancelButtonTitle:@"Ok" otherButtonTitles:nil];
