xcode unknown type name
提问by Esse
I got code like this:
我得到这样的代码：
Match.h:
匹配.h：
#import <Foundation/Foundation.h>
#import "player.h"
@interface Match : NSObject
{
Player *firstPlayer;
}
@property (nonatomic, retain) Player *firstPlayer;
@end
Player.h:
玩家.h：
#import <Foundation/Foundation.h>
#import "game.h"
@interface Player : NSObject
{
}
- (Player *) init;
//- (NSInteger)numberOfPoints;
//- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil;
@property (nonatomic, retain) NSString *name;
@property (nonatomic, retain) NSString *surname;
@property (nonatomic, assign) NSInteger *player_id;
@property (nonatomic, retain) NSString *notes;
@end
Game.h:
游戏.h：
#import <Foundation/Foundation.h>
#import "match.h"
#import "player.h"
@interface Game : NSObject
{
NSMutableArray *matches;
NSMutableArray *players;
NSString *name;
}
-(Game *) init;
@property (nonatomic, retain) NSMutableArray *matches;
@property (nonatomic, retain) NSMutableArray *players;
@property (nonatomic, retain) NSString *name;
@end
Xcode won't compile my project and show me error unknown type 'Player' in Match.h when I declare *firstPlayer.
当我声明 *firstPlayer 时，Xcode 不会编译我的项目并在 Match.h 中向我显示错误未知类型“播放器”。
I tried cleaning project, rebuilding it but without any result...
我尝试清理项目，重建它但没有任何结果......

The normal way to solve this cycles is to forward declare classes:
解决这个循环的正常方法是转发声明类：
In Match.h:
在 Match.h 中：
@class Player;
@interface Match ...
Player * firstPlayer;
and do #import "Player.honly in Match.m, notin Match.h
并且#import "Player.h只在 Match.m、notMatch.h 中执行
Same for the other two .h files.
其他两个 .h 文件也是如此。
