Question

我目前正在开发一个简单的锻炼跟踪器应用程序，我有一个桌面视图，每个锻炼计划数据都会加载到每个细胞上。

我使用字幕作为我在故事板中选择的tableview单元格样式。

我将每个练习名称放在文本标签上，并将详细信息和次数设置到详细标签上。

我的问题是练习数据相对于训练阵列正确加载到每一行的文本标签，但代表和＆amp;设置信息未正确加载。

你可以看到“DEAD LIFT”的字幕标签“15,12,10,8,6”由于某些我无法找到的原因而重复。

根据我设置的数组“reps”，它应该不是那样的。

顺便说一下，这个tableview是从另一个tableview单元格中进行的，这是我代码中的侧面菜单栏tableview单元格。

抱歉由于声誉而无法上传图片

提前谢谢

Answer 1

每次开始新的一天时，切换部分时会重置indexPath.row，导致它从reps数组的开头开始打印。

UITableViewCell字幕无法从数组中正确更新
