FBFriendPickerViewController在FB-IOS SDK3.0中崩溃

我在IOS上的Facebook SDK3.0上工作，我使用developers.facebook.com生成Facebook密钥

my App ID/API Key 165158463618789 

login工作正常，但同时使用FBFriendPickerViewController它崩溃，

我用下面的代码：

  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]; 

而我正在崩溃的原因

Answer 1

我也面临这个问题，但现在我已经解决了这个问题。

使用下面的方法/代码，我解决了问题

在AppDelegate中

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

添加这一行

 [FBFriendPickerViewController class]; 

在你的viewController头文件中添加

 @property (retain, nonatomic) FBFriendPickerViewController *friendPickerController; 

在你的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风格编程。
