筆尖導航線程1：信號SIGABRT

Question

我有一個按鈕在我的ProfileView視圖控制器筆尖調用時按下我去顯示OptionsView視圖控制器。

在我ProfileView.m文件我這是viewDidLoad中：

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

，然後我有：

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

但每當我點擊按鈕，我得到一個線程1：信號SIGABRT與以下控制檯輸出：

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

You hav e SIGABRT，因爲在OptionsView中顯示的tableview數據源沒有從tableView：cellForRowAtIndexPath：方法返回有效的單元格。 您發佈的代碼是確定的。
