我在运行时遇到问题

- [__ NSCFString _isResizable]：无法识别的选择器发送到实例0x6a86a80 2012-10-24 14：21：08.070糖尿病食物指南[767：c07] * 由于未捕获的异常'NSInvalidArgumentException'终止应用程序，原因：' - [__ NSCFString _isResizable]：发送到实例的无法识别的选择器0x6a86a80'

我认为问题出在代码的这些部分：

/*ViewControllerManual.m*/
- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender {
    NSDictionary* tier = (NSDictionary*)sender;
    if ([segue.identifier isEqualToString:@"loopbackSegue"]) {
        ViewControllerManual* nextController = segue.destinationViewController;
        nextController.items = [tier objectForKey:@"items"];
        nextController.title = [tier objectForKey:@"name"];
    } else if ([segue.identifier isEqualToString:@"detailSegue"]) {
        DetailsController* nextController = segue.destinationViewController;
        nextController.name = [tier objectForKey:@"name"];
        nextController.foodPicture = [tier objectForKey:@"foodPicture"];
        nextController.tablePicture = [tier objectForKey:@"tablePicture"];
    }
}

/*DetailsController.m*/

- (void)viewDidLoad {
    [super viewDidLoad];
    nameLbl.text = self.name;
    foodPic.image = self.foodPicture;
    tablePic.image = self.tablePicture;
    }

foodPic和tablePic都是UIImageViews，而foodPic是使用cell.imageView.image = [UIImage imageNamed:[[self.items objectAtIndex:indexPath.row] objectForKey:@"foodPicture"]];设置的从包含图像路径的数组调用。只有在加载DetailsController类的视图时才会出现此错误。如果我需要提供更多信息，请不要犹豫告诉我。

似乎你在这里返回NSStrings：

nextController.foodPicture = [tier objectForKey:@"foodPicture"];
nextController.tablePicture = [tier objectForKey:@"tablePicture"];

然后

// UIImage* = NSString*
nextController.foodPicture = [tier objectForKey:@"foodPicture"];
nextController.tablePicture = [tier objectForKey:@"tablePicture"];

或者你已经发布了一些东西。但是从你的描述来看，更有可能是将NSString分配给UIImage的问题。

图像有问题
