应用崩溃报出错误信息

Question

在UIViewController，添加子视图包含uitableview：

MSEmployeeServiceController *empServices = [ [MSEmployeeServiceController alloc]initWithNibName:@"MSEmployeeServiceController" bundle:nil];
[self.totScroll addSubview:empServices.view];

MSEmployeeServiceController 类中包含了UITableView。每次添加视图时应用都会崩溃：

-[MSEmployeeServiceController numberOfSectionsInTableView:]: message sent to deallocated instance 0x8684030

我已经设置了数据源和代理链接。

如果用ARC，在头文件中将MSEmployeeServiceController 设为property。

@property (strong, nonatomic)  MSEmployeeServiceController *empServices;

在implementation文件中：

_empServices = [ [MSEmployeeServiceController alloc]initWithNibName:@"MSEmployeeServiceController" bundle:nil];
[self.totScroll addSubview:empServices.view];
