Question

我很难在iOS应用中尝试使用FaceBookSDK。

在Xcode中，我创建了一个新项目，单视图应用程序（部署目标：7.1）。

首先，我只想要一个按钮，在点击时向Facebook发布内容。与点击 HelloFacebookSample 应用中的“发布状态更新”按钮时发生的情况类似。我从FacebookSDK（版本3.16.1）提供的 HelloFacebookSample 中复制了一些我认为需要的代码。

以下是我的应用中的代码：

#import "ViewController.h"

@interface ViewController ()
{
    UIButton *fbButton;
}
@end

@implementation ViewController

- (void)viewDidLoad
{
    [super viewDidLoad];

    fbButton=[[UIButton alloc] initWithFrame:CGRectMake(100.0, 150.0, 120.0, 50.0)];
    [fbButton setTitle:@"FB" forState:UIControlStateNormal];
    [fbButton setTitleColor:[UIColor darkGrayColor] forState:UIControlStateNormal];
    [fbButton.titleLabel setFont:[fbButton.titleLabel.font fontWithSize:58.0]];
    [fbButton addTarget:self action:@selector(fbButtonHandler) forControlEvents:UIControlEventTouchUpInside];
    [self.view addSubview:fbButton];
}

- (void)didReceiveMemoryWarning
{
    [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.
}

- (IBAction)fbButtonHandler
{
    NSLog(@"fbButtonHandler CALLED !!!!");
    NSURL *urlToShare = [NSURL URLWithString:@"http://developers.facebook.com/ios"];

    FBLinkShareParams *params = [[FBLinkShareParams alloc] initWithLink:urlToShare
                                                                   name:@"Hello Facebook"
                                                                caption:nil
                                                            description:@"The 'Hello Facebook' sample application showcases simple Facebook integration."
                                                                picture:nil];

    if (![FBDialogs canPresentShareDialogWithParams:params]) {
        NSLog(@"NO canPresentShareDialogWithParams !!!!");
        return;
    }

    FBAppCall *appCall = [FBDialogs presentShareDialogWithParams:params
                                                     clientState:nil
                                                         handler:^(FBAppCall *call, NSDictionary *results, NSError *error) {
                                                             if (error) {
                                                                 NSLog(@"Error: %@", error.description);
                                                             } else {
                                                                 NSLog(@"Success!");
                                                             }
                                                         }];
    if (!appCall)
        NSLog(@"NO appCall !!!!");
}


@end

但是在运行时，没有任何内容发布，我总是收到这条消息：

Oops, Something Went Wrong
There was a problem posting your status. We’ve logged the error and will look into it.

我做错了什么？
