我在运行我的xcode项目时收到错误。我的应用程序总是工作，所以我不明白为什么这不再工作。有人有想法吗？我发现这是由于我打电话的方法无效造成的。我似乎无法弄清楚这个错误所在的位置..有人吗？线程1：信号SIGBRT

你能否显示你的viewCotnroller.h？ –

也许你删除的UIView客体来回在NIB中替换为UIWebView。这很好，但是您应该将webView链接到xib文件中的viewController的"view"属性。

Webview设置为IBOutlet吗？这可能是原因。

的确不错，我ViewController.h： ' #import @interface ViewController：UIViewController {IBOutlet UIWebView * webview; } @property（nonatomic，retain）UIWebView * webview; @ end' – Robbie
