奇怪的未知類型的名稱問題

Question

所以我有這個 -

#import <UIKit/UIKit.h> 
#import "RateView.h" 

@interface BasicCardViewController : UIViewController<RateViewDelegate> 

@property (weak, nonatomic) IBOutlet UILabel *label; 
@property(copy, nonatomic)NSString *message; 
@property(atomic)NSInteger rating; 


@property (strong, nonatomic) IBOutlet RateView *rateView; 
@property (weak, nonatomic) IBOutlet UILabel *ratingLabel; 


@end 

，這 - 在我RateView.h文件。

#import <UIKit/UIKit.h> 
#import "AppDelegate.h" 

@class RateView; 

@protocol RateViewDelegate 
-(void)rateView:(RateView *)rateView ratingDidChange:(float)rating; 
@end 



@interface RateView : UIView 

@property(strong,nonatomic)UIImage* fullSelectedStar; 
@property(strong,nonatomic)UIImage* notSelectedStar; 
@property(strong, nonatomic)UIImage* halfSelectedStar; 
@property (assign, nonatomic)float rating; 
@property(assign) BOOL editable; 
@property (strong) NSMutableArray* imageViews; 
@property(assign,nonatomic) int maxRating; 
@property(assign) int midMargin; 
@property(assign)int leftMargin; 
@property (assign) CGSize minImageSize; 
@property (assign) id <RateViewDelegate> delegate; 

@end 

，但我得到兩個錯誤 -

1.Cannot找到 'TooviaRateViewDelegate' 2.Unknown類型名稱 「RateView」

我試圖清理協議聲明，我已經證實這些文件是他們應該在的地方（他們的文件路徑是該項目的）。

這是怎麼發生的？

編輯 - 我AppDelegate.h

#import <UIKit/UIKit.h> 
#import "SearchViewController.h" 

@interface TooviaAppDelegate : UIResponder <UIApplicationDelegate> 

@property (strong, nonatomic) UIWindow *window; 
@property NSOperationQueue *queue; 
@property (strong, nonatomic) NSDictionary *userProfile; 
@property (strong, nonatomic) SearchViewController *searchViewController; 

- (NSOperationQueue*) getOperationQueue; 
- (id)getSettings:(NSString *)keyPath; 
- (void) saveCookies; 


@end 

也有問題，我SearchViewController

#import <UIKit/UIKit.h> 
#import "BasicCardViewController.h" 

@interface SearchViewController : UIViewController 
    <UISearchBarDelegate, UISearchDisplayDelegate, UITableViewDataSource, UITableViewDelegate> 
- (IBAction)searchButtonClicked:(UIButton *)sender; 
- (IBAction)backgroundTap:(id)sender; 

@property (weak, nonatomic) IBOutlet UITableView *resultTable; 
@property (weak, nonatomic) IBOutlet UITextField *searchBar; 
@property (strong, nonatomic) NSArray *resultsTuples; 
@property (weak, nonatomic) IBOutlet UIButton *searchButton; 
@property (copy, nonatomic) NSArray *controllers; 
@property(strong,nonatomic)BasicCardViewController *detailController;

委託和數據源的屬性通常標記爲前面所描述的對象圖管理的原因是軟弱的，在「Avoid Strong Reference Cycles。「
