Ios 如何根据objective c中的数组计数启用和禁用tableview单元格
我是iOS新手，我面临着根据数组计数启用和禁用单元格的问题 我的代码是这样的Ios 如何根据objective c中的数组计数启用和禁用tableview单元格,ios,objective-c,arrays,uitableview,Ios,Objective C,Arrays,Uitableview,我是iOS新手，我面临着根据数组计数启用和禁用单元格的问题 我的代码是这样的 countcellbtn.text=[NSString stringWithFormat:@"%lu",(unsigned long)ComplareArray.count]; 我正在获取数组计数，我需要根据数组计数禁用单元格 确切的问题：我在按钮上点击了按钮，我正在保存数据 核心数据和弹出窗口我更新它。所以如果我直接点击 第三排应用程序崩溃 提前谢谢！ 我在点击按钮时保存数据，在弹出式点击时更新数据，如下所示
