我有一个应用程序，您可以在其中获得某些事物的一些详细信息，然后在该事物内部有一个事物的子类别。我制作了一个按钮，因为导航项没有足够的空间，而且我似乎无法仅调用在我的 nsmutablearray 中分配给它的项目。我尝试过使用initWithIndexPath:indexPath.row它，但它出现了这个错误：
使用未声明的标识符“indexPath”；你的意思是“NSIndexPath”吗
这是我的 tableView 中的 tableView 的代码：
#import "PRViewController.h"
#import "Patient.h"
#import "LSAppDelegate.h"
#import "LSViewController.h"
#import "LSAppDelegate.h"
#import "Patient.h"
#import "PatientController.h"
#import "AddPatientController.h"
#import "treatmentController.h"
@interface PRViewController ()
