Question

我在IOS上使用Facebook SDK3.0，我使用developers.facebook.com

生成Facebook密钥

my App ID/API Key 
165158463618789

登录工作正常，但在使用FBFriendPickerViewController时会崩溃，

我使用了以下代码：

   FBFriendPickerViewController *friendPicker = [[FBFriendPickerViewController alloc]     init];
   self.friendPickerController = friendPicker;

   [friendPicker loadData];
   friendPicker.navigationItem.title = @"Pick Friends";
   friendPicker.navigationItem.rightBarButtonItem = [[UIBarButtonItem alloc] 
                                                  initWithTitle:@"Done" 
                                                  style:UIBarButtonItemStyleBordered 
                                                  target:self 
                                                                 action:@selector(doneButtonWasPressed:)];
    friendPicker.navigationItem.leftBarButtonItem = [[UIBarButtonItem alloc] 
                                                 initWithTitle:@"Cancel" 
                                                 style:UIBarButtonItemStyleBordered 
                                                 target:self 
                                                 action:@selector(cancelButtonWasPressed:)];
 [self.navigationController pushViewController:friendPicker animated:YES];

我也遇到了这个问题，但现在我已经解决了。

使用以下方法/代码，我解决了问题

在AppDelegate中

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions

添加此行

[FBFriendPickerViewController class];

在viewController头文件中添加

@property (retain, nonatomic) FBFriendPickerViewController *friendPickerController;

在viewController实现文件中添加一个函数

if (self.friendPickerController == nil) {
    // Create friend picker, and get data loaded into it.
    self.friendPickerController = [[FBFriendPickerViewController alloc] init];
    self.friendPickerController.title = @"Pick Friends";
    self.friendPickerController.delegate = self;
}

[self.friendPickerController loadData];
[self.friendPickerController clearSelection];

[self presentModalViewController:self.friendPickerController animated:YES];

所以我没有使用导航控制器样式编程。
