uiviewcontroller - -[UIView setShowsFPS :]: unrecognized selector error

Question

我需要在按下 UIButton 时打开一个 ViewController，为此我使用以下命令代码:

NSString * storyboardName = @"Main";
UIStoryboard *storyboard = [UIStoryboard storyboardWithName:storyboardName bundle: nil];
UIViewController * vc = [storyboard instantiateViewControllerWithIdentifier:@"ViewController"];
[self presentViewController:vc animated:YES completion:nil];

当它走完最后一行

[self presentViewController:vc animated:YES completion:nil];

它给我以下错误:

-[UIView setShowsFPS:]: unrecognized selector sent to instance 0x9bd5610 2013-07-16 14:40:52.728 ChainZoo[3026:a0b] * Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[UIView setShowsFPS:]: unrecognized selector sent to instance 0x9bd5610'

有人知道错误吗？提前致谢!!

在 storyborad 上，选择您的 ViewController 的 View 并点击“Show the identity inspector”(右上角的第三个小标签) .

您将看到自定义类 TextView 。

写入“SKView”并再次尝试运行。

您应该将 VC 的 View 初始化为 SKView。
