Question

我试图用我的手脚,但显然我真的 s着,甚至在照抄法典时,也这样做! I veed at this tutorial:

我的档案中有3个错误。我从上至下的整个卷宗就是这样:

//
//  GGImageLoader.h
//  
//
//  Copyright 2011 __MyCompanyName__. All rights reserved.
//

#import <UIKit/UIKit.h>


@protocol GGImageLoader 

// Asynchronous Image loading
@interface GGImageLoader : NSObject { // ERROR - "No type or storage class may be specified here before  interface "

    NSURLConnection * connection;

    NSURL * url;

    NSMutableData * mutData;

    UIImage * image;

    id delegate;

}

@property ( nonatomic, retain ) UIImage * image;

- (id)initWithURL:(NSURL *)aURL;
- (void)setDelegate:(id)anObject;
- (void)load;

@end

@protocol GGImageLoaderProtocol // ERROR - "No type or storage class may be specified here before  interface "

@required
- (void)imageLoader:(GGImageLoader *)loader
       didLoadImage:(UIImage *)anImage;

@optional
- (void)imageLoader:(GGImageLoader *)loader
    didReceiveError:(NSError *)anError;

@end
//

我所发现的错误是上文法典的后面写的,第3条是“在`相互”的情况下发表的友好声明。

我确实赞赏任何建议。
