ios – 动态改变目标C中单元格的高度

概述我创建了一个带有表格视图的应用程序.它使用每个单元格中的视图和标签.但是如果我在(！单元格)代码中创建视图和单元格,它将返回空单元格,如果我删除(！单元格)条件,它将显示数据但不采用动态高度.谁能帮帮我吗. - (void)viewDidLoad{ NSString *Path = [[NSBundle mainBundle] bundlePath];NSString *DataPath = 我创建了一个带有表格视图的应用程序.它使用每个单元格中的视图和标签.但是如果我在(！单元格)代码中创建视图和单元格,它将返回空单元格,如果我删除(！单元格)条件,它将显示数据但不采用动态高度.谁能帮帮我吗.

提前致谢.

解决方法 这是我在我的应用程序中使用的代码的一部分.它对我很有用.如果你需要帮助,请打电话给我.
