找不到协议声明ios7

Question

我在文件ScrollableTimelineViewProtocol中声明了一个名为ScrollableTimelineView.h的协议，如下所示：

#import <UIKit/UIKit.h>
#import "AbstractView.h"
#import "RedTimeIndicator.h"
#import "EventsModel.h"
#import "TimeStrands.h"
#define LABEL_TAG_OFFSET -500

@protocol ScrollableTimelineViewProtocol <NSObject>
- (void) showPopup : (NSInteger)tag;

@end



@interface ScrollableTimelineView : UIView<TimeStrandDelegate,UIScrollViewDelegate>
{
}
@property (nonatomic,assign) id<ScrollableTimelineViewProtocol> delegate;

我试图在视图控制器中使用它：

#import <UIKit/UIKit.h>
#import "AbstractViewController.h"
#import "TimeStrands.h"
#import "ScrollableTimelineView.h"


@protocol TimelineDelegate <NSObject>
- (void) detailedShownDelegate;
- (void) detailedViewHiddenDelegate;

@end

@interface TimelineViewController : UIViewController<ScrollableTimelineViewProtocol>;

但是我说Could not find protocol declartion for ScrollableTimelineViewProtocol时出错了。帮助。

Answer 1

1. 结尾不应该有分号。
2. 导入ScrollableTimelineViewProtocol声明的类。

Answer 2

@protocol scrollableTimelineViewProtocol;

@property (strong, nonatomic) IBOutlet UITableView *tblView;
@property (strong, nonatomic) IBOutlet id<scrollableTimelineViewProtocol> delegate;

@end
@protocol scrollableTimelineViewProtocol <NSObject>

-(void)runFast;

@end

Answer 3

很简单..。试试这个..。

从接口中删除分号。

@interface TimelineViewController : UIViewController<ScrollableTimelineViewProtocol>;

转到

@interface TimelineViewController : UIViewController<ScrollableTimelineViewProtocol>
