ios - 添加图像时静态 TableView 崩溃

Question

所以我正在为我的一个 friend 做一些事情，我遇到了一些问题。对于每个武器类别，我都有一系列文本和图像。该应用程序运行良好，但后来我添加了图像，现在它崩溃了。看一看，如果您对发生的事情有任何想法，请告诉我。谢谢!

Answer 1

我认为问题在于缺少正确定义 if/else 语句范围的括号。在 cellForRowAtIndexPath:

中查看此代码

int row = [indexPath row];

if (indexPath.section==0)
    cell.TitleLabel.text = _assault[row];
    cell.myImageView.image = [UIImage imageNamed:_assault1[row]];

else ... 

每次调用 cellForRowAtIndexPath 时都会运行此行，无论您的 indexPath 在哪个部分:

cell.myImageView.image = [UIImage imageNamed:_assault1[row]];

将大括号添加到您的 if/else 条件中，您将确保您引用的行位于正确的部分。
