当我去行号时。DistanceViewController.m 中的 140（崩溃点，如日志所示），我发现：
cell.backgroundImage.image = barImage;
其中“barImage”是在此类中定义的 UIImage，并在 initWithNibName 方法中初始化为：
barImage = [UIImage imageNamed:@"Bar.png"];
我没有释放 barImage，因为我没有在任何地方分配/保留它。此外，distanceViewController 的 initWithNibName 仅在应用程序中调用一次。
谁能指出我应该专注于摆脱这里的崩溃？
