不明白爲什麼我會得到「方法定義未找到錯誤」

Question

我不得不將一些現有代碼從AppDelegate中移出並將其放在普通類中，以便應用程序不必重新啓動。在我做這件事之前，一切都在沒有錯誤的情況下建立並正確執行。這是我的.h文件中的代碼：

#import <Foundation/Foundation.h> 
#import "AppDelegate.h" 
#import "SingletonClass.h" 
#import "SettingsViewController.h" 
#import "CoreData+MagicalRecord.h" 

@interface CommonMethods : NSObject { 

} 

@property (nonatomic, strong) NSMutableArray *unsortedNailArray; 
@property (nonatomic, strong) NSMutableArray *unsortedHairArray; 
@property (nonatomic, strong) NSMutableArray *unsortedCustomArray; 

-(void) sortAndReloadServicesArray: (NSMutableArray *) textboxValues; 
-(void) initalizeEnsembles; 

-(void) displayAlert: (NSString *)alertTitle andMessage: (NSString *)alertMessage andViewController: (UIViewController *) viewController andTag:(int)tag; 
-(NSMutableDictionary *) createStaffNamesDictionary; 
-(NSMutableArray *) createStaffNamesArray; 
-(BOOL)testConnectionToInternet; 

-(void) initializeEnsembles; // definition that is missing? 

- (NSString *) convert12HourTimeTo24HourTime: dateString andReturnType: (NSString *) dateOrDateTime; 
- (NSString *) convert24HourTimeTo12HourTime: (NSString *)timeString; 
- (NSNumber *) checkForApptOverlap: startTime andStopTime: stopTime andServiceTech: serviceTech; 

@end 

這是相關的.m文件：

#import "CommonMethods.h" 

@interface CommonMethods() <CDEPersistentStoreEnsembleDelegate> 
@end 

@implementation CommonMethods { 

CDEPersistentStoreEnsemble *ensemble; 
CDEICloudFileSystem *cloudFileSystem; 
} 

@synthesize unsortedNailArray; 
@synthesize unsortedHairArray; 
@synthesize unsortedCustomArray; 


#pragma mark - initializeEnsembles 
-(void) initializeEnsembles { // <---- here it is! 

// set Ensembles verbose logging 
CDESetCurrentLoggingLevel(CDELoggingLevelVerbose); 

// Ensemble: load the model 
NSManagedObjectModel *model = [NSManagedObjectModel MR_newManagedObjectModelNamed:@"salonbook.momd"]; // (xcdatamodeld) 
[NSManagedObjectModel MR_setDefaultManagedObjectModel:model]; 

Answer 1

也有同樣的方法聲明

-(void) initalizeEnsembles; 

沒有isortAndReloadServicesArray
