Question

为什么在创建编辑此文件后，我的所有源文件中都会出现上述编译错误:

#import <UIKit/UIKit.h>

@protocol FlipsideViewControllerDelegate;


@interface FlipsideViewController : UIViewController {
    id <FlipsideViewControllerDelegate> delegate;
    UITextField *textField;
}
@property (nonatomic, retain) IBOutlet UITextField *textField;


@property (nonatomic, assign) id <FlipsideViewControllerDelegate> delegate;
- (IBAction)done:(id)sender;
@end


@protocol FlipsideViewControllerDelegate
- (void)flipsideViewControllerDidFinish:(FlipsideViewController *)controller;
@end

-(IBAction) textChanged:(id) sender;

编辑我的 Flipsidecontroller.h 后看起来像这样。我在所有其他源文件中都收到错误。比如这个:

    //  MainViewController.h
//  MVC
//
//  Created by Nick Martin on 3/31/11.
//  Copyright 2011 Nick. All rights reserved.
//

#import "FlipsideViewController.h"

@interface MainViewController : UIViewController <FlipsideViewControllerDelegate> {
    UILabel *label;
}

@property (nonatomic, retain) IBOutlet UILabel *label;

- (IBAction)showInfo:(id)sender;

@end

它提示我的每个 Controller 的接口(interface)声明？？？

预先感谢您的帮助!

更新 - 将textChanged事件放入界面

//  FlipsideViewController.h
//  MVC
//
//  Created by Nick Martin on 3/31/11.
//  Copyright 2011 Nick Martin. All rights reserved.
//

#import <UIKit/UIKit.h>


@protocol FlipsideViewControllerDelegate;


@interface FlipsideViewController : UIViewController {
    id <FlipsideViewControllerDelegate> delegate;
    UITextField *textField;
}
@property (nonatomic, retain) IBOutlet UITextField *textField;


@property (nonatomic, assign) id <FlipsideViewControllerDelegate> delegate;
- (IBAction)done:(id)sender;
@end

-(IBAction) textChanged:(id) sender;  //DOH!!! 

@protocol FlipsideViewControllerDelegate
- (void)flipsideViewControllerDidFinish:(FlipsideViewController *)controller;
@end

Answer 1

您的 textChanged: 方法不在接口(interface)或协议(protocol)中。您是否打算将其包含在 FlipsideViewController 或 FlipsideViewControllerDelegate 中？
