Question

我的ProfileView视图控制器nib中有一个按钮，当按下时我会显示OptionsView视图控制器。

在我的ProfileView.m文件中，我有这个是viewDidLoad：

self.navigationItem.leftBarButtonItem = [[UIBarButtonItem alloc] initWithTitle:@"Options"     style:UIBarButtonItemStylePlain target:self action:@selector(actionOptions)];

然后我有：

- (void)actionOptions
{
    OptionsView *screen = [[OptionsView alloc] initWithNibName:@"OptionsView" bundle:Nil];
  [self.view addSubview:screen.view];
}

但每当我点击按钮时，我会得到一个线程1：信号 SIGABRT ，并带有以下控制台输出：

2014-11-24 13:43:54.107 app[2161:5537921] didFailToRegisterForRemoteNotificationsWithError Error Domain=NSCocoaErrorDomain Code=3010 "remote notifications are not supported in the simulator" UserInfo=0x7ff7c2c365d0 {NSLocalizedDescription=remote notifications are not supported in the simulator}

Answer 1

你有SIGABRT，因为在OptionsView中显示的tableview的数据源没有从tableView：cellForRowAtIndexPath：方法返回有效的单元格。您发布的代码没问题。
