Ios 向新控制器添加新委托时出现问题

我正在尝试找出如何在LocationViewController和SetCorringTableViewController中获取代理，并在GameDetailsTableViewController中实现这两个代理。LocationViewControllerDelegate已在工作，但当我添加新的SetCoringTableViewController时，程序出现错误

LocationViewController.h

#import "ViewController.h"

@class LocationViewController;

 @protocol LocationViewControllerDelegate <NSObject>

- (void)addItemViewController:(LocationViewController *)controller didFinishEnteringItem:(NSString *)name;

 @end

@interface LocationViewController : UIViewController
  @property (nonatomic, weak) id <LocationViewControllerDelegate> delegate;
    @end

#import <UIKit/UIKit.h>
#import "GameDetailsTableViewController.h"
#import "LocationViewController.h"

@class SetScoringTableViewController;

@protocol SetScoringTableViewControllerDelegate <NSObject>

- (void)addItemViewControllerSS:(SetScoringTableViewController *)SScontroller didFinishEnteringItemSS:(NSString *)SSname;

@end

 @interface SetScoringTableViewController : UITableViewController
    @property (nonatomic, strong) id <SetScoringTableViewControllerDelegate> SSdelegate;

    @end

#import <UIKit/UIKit.h>
#import "LocationViewController.h"
#import "SetScoringTableViewController.h"

@interface MainViewController : UITableViewController  <LocationViewControllerDelegate, SetScoringTableViewControllerDelegate>

#import "GameDetailsTableViewController.h"

#import "SetScoringTableViewController.h"

设置CorringTableViewController.h

#import "ViewController.h"

@class LocationViewController;

 @protocol LocationViewControllerDelegate <NSObject>

- (void)addItemViewController:(LocationViewController *)controller didFinishEnteringItem:(NSString *)name;

 @end

@interface LocationViewController : UIViewController
  @property (nonatomic, weak) id <LocationViewControllerDelegate> delegate;
    @end

#import <UIKit/UIKit.h>
#import "GameDetailsTableViewController.h"
#import "LocationViewController.h"

@class SetScoringTableViewController;

@protocol SetScoringTableViewControllerDelegate <NSObject>

- (void)addItemViewControllerSS:(SetScoringTableViewController *)SScontroller didFinishEnteringItemSS:(NSString *)SSname;

@end

 @interface SetScoringTableViewController : UITableViewController
    @property (nonatomic, strong) id <SetScoringTableViewControllerDelegate> SSdelegate;

    @end

#import <UIKit/UIKit.h>
#import "LocationViewController.h"
#import "SetScoringTableViewController.h"

@interface MainViewController : UITableViewController  <LocationViewControllerDelegate, SetScoringTableViewControllerDelegate>

#import "GameDetailsTableViewController.h"

#import "SetScoringTableViewController.h"

gamedetailstablevewcontroller.h

#import "ViewController.h"

@class LocationViewController;

 @protocol LocationViewControllerDelegate <NSObject>

- (void)addItemViewController:(LocationViewController *)controller didFinishEnteringItem:(NSString *)name;

 @end

@interface LocationViewController : UIViewController
  @property (nonatomic, weak) id <LocationViewControllerDelegate> delegate;
    @end

#import <UIKit/UIKit.h>
#import "GameDetailsTableViewController.h"
#import "LocationViewController.h"

@class SetScoringTableViewController;

@protocol SetScoringTableViewControllerDelegate <NSObject>

- (void)addItemViewControllerSS:(SetScoringTableViewController *)SScontroller didFinishEnteringItemSS:(NSString *)SSname;

@end

 @interface SetScoringTableViewController : UITableViewController
    @property (nonatomic, strong) id <SetScoringTableViewControllerDelegate> SSdelegate;

    @end

#import <UIKit/UIKit.h>
#import "LocationViewController.h"
#import "SetScoringTableViewController.h"

@interface MainViewController : UITableViewController  <LocationViewControllerDelegate, SetScoringTableViewControllerDelegate>

#import "GameDetailsTableViewController.h"

#import "SetScoringTableViewController.h"

运行此操作时，我遇到一个错误：无法找到“SetCoringTableViewControllerDelegate”的协议声明，即使我已经找到了。

我发现解决此问题的唯一方法是将SetCoringTableViewController委托放在LocationView控制器中，但我知道这是不对的。任何帮助都将不胜感激。

尝试在不同的.h文件中分离该委托。

尝试在不同的.h文件中分离该委托。

您有一个依赖项循环：

设置CorringTableViewController.h

#import "ViewController.h"

@class LocationViewController;

 @protocol LocationViewControllerDelegate <NSObject>

- (void)addItemViewController:(LocationViewController *)controller didFinishEnteringItem:(NSString *)name;

 @end

@interface LocationViewController : UIViewController
  @property (nonatomic, weak) id <LocationViewControllerDelegate> delegate;
    @end

#import <UIKit/UIKit.h>
#import "GameDetailsTableViewController.h"
#import "LocationViewController.h"

@class SetScoringTableViewController;

@protocol SetScoringTableViewControllerDelegate <NSObject>

- (void)addItemViewControllerSS:(SetScoringTableViewController *)SScontroller didFinishEnteringItemSS:(NSString *)SSname;

@end

 @interface SetScoringTableViewController : UITableViewController
    @property (nonatomic, strong) id <SetScoringTableViewControllerDelegate> SSdelegate;

    @end

#import <UIKit/UIKit.h>
#import "LocationViewController.h"
#import "SetScoringTableViewController.h"

@interface MainViewController : UITableViewController  <LocationViewControllerDelegate, SetScoringTableViewControllerDelegate>

#import "GameDetailsTableViewController.h"

#import "SetScoringTableViewController.h"

gamedetailstablevewcontroller.h

#import "ViewController.h"

@class LocationViewController;

 @protocol LocationViewControllerDelegate <NSObject>

- (void)addItemViewController:(LocationViewController *)controller didFinishEnteringItem:(NSString *)name;

 @end

@interface LocationViewController : UIViewController
  @property (nonatomic, weak) id <LocationViewControllerDelegate> delegate;
    @end

#import <UIKit/UIKit.h>
#import "GameDetailsTableViewController.h"
#import "LocationViewController.h"

@class SetScoringTableViewController;

@protocol SetScoringTableViewControllerDelegate <NSObject>

- (void)addItemViewControllerSS:(SetScoringTableViewController *)SScontroller didFinishEnteringItemSS:(NSString *)SSname;

@end

 @interface SetScoringTableViewController : UITableViewController
    @property (nonatomic, strong) id <SetScoringTableViewControllerDelegate> SSdelegate;

    @end

#import <UIKit/UIKit.h>
#import "LocationViewController.h"
#import "SetScoringTableViewController.h"

@interface MainViewController : UITableViewController  <LocationViewControllerDelegate, SetScoringTableViewControllerDelegate>

#import "GameDetailsTableViewController.h"

#import "SetScoringTableViewController.h"

但是看起来您可以删除导入GameDetailsStableViewController.h，因为头文件中没有提到它。

您正在经历的是一个导入周期。打破导入循环 删除此导入行：

#import "GameDetailsTableViewController.h"

从SetCoringTableViewController.h中，将其放入.m文件中。
