由于未被捕获的'NSUnknownKeyException'而终止应用，

Question

不断为此代码收到此错误 我在

处使用了断点

GameSelect *selectGame = [[GameSelect alloc] initWithNibName:nil bundle:nil];

我不知道发生了什么事 我只是从一个笔尖切换到另一个笔尖

- (IBAction)playButtonPressed:(UIButton *)sender {
    GameSelect *selectGame = [[GameSelect alloc] initWithNibName:nil bundle:nil];
    selectGame.modalTransitionStyle = UIModalTransitionStyleCoverVertical;
    [self presentModalViewController:selectGame animated:YES];
}

Answer 1

您的initWithNibName设置为nil。你应该为你的笔尖命名。

Answer 2

尝试将你的nib文件名放在这里：GameSelect * selectGame = [[GameSelect alloc] initWithNibName：@“”bundle：nil];

Answer 3

如下所示，

- (IBAction)playButtonPressed:(UIButton *)sender 
{
    GameSelect *selectGame = [[GameSelect alloc] initWithNibName:@"GameSelect" bundle:nil];
    selectGame.modalTransitionStyle = UIModalTransitionStyleCoverVertical;
    [self presentModalViewController:selectGame animated:YES];
}

如果您的笔尖名称是任何其他名称而不是“GameSelect”，请提供“您的笔尖名称”。
