我已经完成了两个视频,并使用以下代码将视图控制器与父视图控制器连接起来：

- (IBAction)searchButtonClicked:(id)sender {
    NSLog(@"It works.");

    SearchViewController *searchViewControl = [self.storyboard instantiateViewControllerWithIdentifier:@"SearchControllerNav"];

    [self presentViewController:searchViewControl animated:YES completion:nil];

}

这段代码确实有效,因为这与我用于其他模态视图控制器的格式相同,所以我知道这不是问题.

无论如何,当我点击视图控制器中的搜索按钮时,它应该弹出SearchViewController.但是,应用程序崩溃了,它给了我这个错误信息：

Terminating app due to uncaught exception 'NSInternalInconsistencyException',reason: '-[UITableViewController loadView] loaded the "jp7-vt-IdA-view-Jer-xW-qlD" nib but didn't get a UITableView.'

我正在为这个应用程序使用Storyboard.

有什么东西我不见了吗？先感谢您.

一个附带问题：我也收到一个警告,说当指示isFiltered == YES时,指针和整数之间的比较(‘BOOL *'(又名’signed char *’)和’int’).无论如何要解决它吗？

这是SearchViewController的代码：

SearchController.h

#import <UIKit/UIKit.h>

@interface SearchViewController : UITableViewController <UITableViewDelegate,UITableViewDataSource,UISearchBarDelegate> {

}
- (IBAction)cancelButtonTapped:(id)sender;

@property (weak,nonatomic) IBOutlet UISearchBar *mySearchBar;
@property (weak,nonatomic) IBOutlet UITableView *myTableView;

@property (nonatomic,strong) NSMutableArray *itemsInCloudApp;
@property (nonatomic,strong) NSMutableArray *filteredList;
@property BOOL *isFiltered;


@end

SearchViewController.m

#import "SearchViewController.h"

@interface SearchViewController ()
