objective-c - '发送到实例的无法识别的选择器'

Question

我收到以下错误

[UIViewController setThisViewData:]: unrecognized selector sent to instance 0x71800b0
2012-10-24 16:06:05.071 Movie Rental[5468:c07] *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[UIViewController setThisViewData:]: unrecognized selector sent to instance 0x71800b0'

在“ basicInfoViewController.m ”的以下行：

 contactInfoViewController *destViewController = segue.destinationViewController;
 destViewController.thisViewData = [[NSMutableDictionary alloc] initWithDictionary:self.viewData];

我的contactInfoViewController.h看起来像

@interface contactInfoViewController : UIViewController
{
    NSMutableDictionary *thisViewData;
}
@property(nonatomic, strong) NSMutableDictionary *thisViewData;

我已经包括了

@synthesize thisViewData;

为实施。为什么我会收到此错误？

看起来您还没有在界面构建器中为 UIViewController 设置类，因此您没有获得 contactInfoViewController，而是获得了 UIViewController。
