Ios CloudKit执行

我的应用程序中存在CloudKit问题。最初加载视图时，数据会完全加载。但当我“拉刷新”时，我得到一个“致命错误：索引超出范围”。奇怪的是，代码上并没有区别（至少对我来说是这样）。 当我拉刷新时，它甚至不运行“perform”（“B”不会被打印）。 调试器不显示任何错误

你有线索吗

提前谢谢

loadCloudData

函数所做的第一件事是将

dataCloud

数组设置为空数组，但不在tableview上调用

reloadData

，因此数组中的项数和tableview认为在数组中的项数是不同的

您应该在清除数组后调用

reloadData

，或者不清除数组

我删除了“dataCloud=[CKRecord]（）”，一切正常！我不知道为什么我没有考虑把它拿走。谢谢！！！
