iOS - 自定义视图崩溃
该项目因此错误而崩溃。
2011-08-08 19:34:27.539 MCIT[12233:207] -[TrailersViewController initWithFrame:]: unrecognized selector sent to instance 0x58396e0
2011-08-08 19:34:27.542 MCIT[12233:207] *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[TrailersViewController initWithFrame:]: unrecognized selector sent to instance 0x58396e0'
在此方法中，欢迎对委托提出
-(void)switchToTrailerOne
{
CGSize screenSize = [UIScreen mainScreen].bounds.size;
CGRect screenBounds = CGRectMake(0, 0, screenSize.width, screenSize.height);
TrailersViewController *trailersController = [[TrailersViewController alloc] initWithFrame:screenBounds];
[self.navController pushViewController:trailersController animated:NO];
[trailersController goToFirstTrailer];
}
问题，但如果您想查看代码，则有问题的视图控制器文件位于此处。

您正在尝试在 UIViewController 上 initWithFrame 。您将在 UIView 子类上使用 initWithFrame。您收到的错误是正确的，因为 UIViewController 不会响应该消息，因为它没有 initWithFrame 选择器。您可以在 UIViewController 内设置 UIViewController 的视图属性框架。
You are trying to initWithFrame on a UIViewController. You will use initWithFrame on UIView subclasses. The error you are getting is correct because UIViewController won't respond to that message because it doesn't have an initWithFrame selector. You can set the UIViewController's view property frame within the UIViewController.
