Question

在我的头文件GuiController.h中：

#import <Cocoa/Cocoa.h>
#import <APPKit/NSTextField.h>
#import "ClientSocket.h"
#import "UploaderThread.h"
#import "DownloaderThread.h"

@class AppDelegate; //compiler error
@interface GuiController : NSObject {
    AppDelegate * appDelegate;
    NSSound *sound;
    NSString *port;
    NSString *host;
    ClientSocket *mainSock;
    ClientSocket *songSock;
    UploaderThread *uploader;
    int ident;
    NSTextField *albTB;
    NSComboBox *titCB;
    NSTextField *authTB;

}
- (id) initWithDelegate: (AppDelegate*) theDelegate
               host: (NSString*) hostName
               port: (NSString*) portNum;
- (void) dealloc;

- (void) saveLib;
- (void) restoreLib;
- (void) addMD;
- (void) removeMD;
- (void) refreshMD;
- (void) playMD;
- (void) comboBoxSelectionDidChange: (NSNotification*)notification;
- (void) debug: (NSString*) aMessage;
@end

我标记了引发错误的行，即使看起来没有错误。我99％肯定编译器抛出错误只是因为感觉就像它。你能弄明白这个问题吗？

Answer 1

检查您的DownloaderThread.h文件。你可能在结尾处有一个错误。

或者，从未编译为Obj-C或Obj-C ++的源文件导入GuiController.h。虽然如果是这种情况我会期待更快的错误（在其中一个导入的标题中）。

Objective-C问题 - 期望的标识符或'（'在课前
