Ios 如何解决Swift中消失/不可见/空UITableViewCells的问题？
我有两个Ios 如何解决Swift中消失/不可见/空UITableViewCells的问题？,ios,swift,uitableview,uitextfield,uipickerview,Ios,Swift,Uitableview,Uitextfield,Uipickerview,我有两个viewcontroller，一个是GoalsViewController，另一个是AddNewGoalViewController GoalsViewController用于删除目标（单元格）和添加新目标（单元格）。有一个UITableView和一个按钮，添加新目标。当用户按下添加新目标按钮时，它将传递到AddNewGoalViewController。在AddNewGoalViewController中，用户将选择训练、通知（他们希望收到通知的次数）以及他们希望跑步、步行或做任何其他
