ios - 确定事故原因

Question

我的应用程序使用 Parse。它将“Prayers”类中的所有对象放入 TableView 中。当它加载时，它会记住所有以前加载的项目，并搜索新的项目。从今天开始，添加新项目时它开始崩溃。我的崩溃日志看起来像这样，有什么想法吗？:

Answer 1

这些行似乎表明您的崩溃是由于尝试访问数组中不存在的索引引起的:

1 libobjc.A.dylib 0x1964340e4 objc_exception_throw + 60 2 CoreFoundation 0x185bc762c -[__NSArrayM objectAtIndex:] + 264

如果您需要任何进一步的帮助，我建议您发布表格 View 方法的内容。
