应用程序不在Xcode 5.1.1模拟器上运行

Question

我对Objective-C相当陌生，我在autoReleasepool块中获得线程1：信号SIGBRT。

这是我的代码：我只向这两个文件添加了代码。我还将3个图像导入到支持文件文件夹中。

    // set the player to 1 
    playerToken = 1; 
    // update the label 
    whoseTurn.text =@"X will go first!";

*** Terminating app due to uncaught exception 'NSUnknownKeyException', reason: '[<ViewController 0x109356bd0> setValue:forUndefinedKey:]: this class is not key value coding-compliant for the key sd.' ***

这通常意味着你使用在您删除的文件中有一个IBOutlet，但您忘记从Interface Builder中的xib或故事板中删除连接。寻找一个名为sd的房产，该房产不应该在那里。
