CoreDataの問題 - 認識できないセレクタがインスタンスに設定されています

Question

私は他の人からプロジェクトを継承しており、古いバージョンのXcodeで作成されています。アップグレードすると私は修正しなければならないものがいくつか見つかりましたが、これは私にとって困っています。

Xcode（NSManagedObject）によって生成されたクラスを持つCoreDataモデルがあります。私はSpeakerクラスを使ってスピーカー属性を含むMeetingオブジェクトを持っています。関係は、すべての場所にあるが、会議インスタンスのスピーカーの属性を割り当てることで、最初の試行で私は、次を得る：

マイミーティングクラスは、型スピーカー*のスピーカー属性を持っている、との.mですべてが持っています@ getter/setterを作成する動的ステートメントすべてのヘルプは大歓迎です

+ (void) addSpeakerWithDictionary: (NSDictionary *) speakerDict forMeeting: (Meeting *) aMeeting 
{ 
    int speakerID = [speakerDict[@"id"] intValue]; 
    NSPredicate *predicate = [NSPredicate predicateWithFormat:@"identification = %d AND %@ IN meeting", speakerID, aMeeting]; 
    NSArray *speakersArray = [CoreDataManager fetchObjects:@"Speaker" withSortDescriptors:nil andPredicate:predicate]; 

    if (speakersArray.count == 0) 
    { 
     Speaker *speaker = [NSEntityDescription insertNewObjectForEntityForName:@"Speaker" inManagedObjectContext:[CoreDataManager managedObjectContext]]; 

     speaker.degree =   speakerDict[@"degree"]; 
     speaker.firstName =  speakerDict[@"firstName"]; 
     speaker.identification = @(speakerID); 
     speaker.lastName =  speakerDict[@"lastName"]; 
     speaker.preTitle =  speakerDict[@"preTitle"]; 
     speaker.version =  speakerDict[@"version"]; 

     aMeeting.speaker = speaker; 

    }

は、ここでは、コードです。ありがとう！

編集：

+ (void) insertMeetingsFromArray: (NSArray *) meetingsArray 
{ 
    for (NSDictionary *dict in meetingsArray) 
    { 
     NSPredicate *predicate = [NSPredicate predicateWithFormat:@"identification = %d AND user = %@", [dict[@"id"] intValue], SessionManagerInstance.loggedUser]; 
     NSArray *meetArray = [CoreDataManager fetchObjects:@"Meeting" withSortDescriptors:nil andPredicate:predicate]; 

     if (meetArray.count) 
     { 
      Meeting *meeting = meetArray[0]; 
      [CoreDataManager addSpeakerWithDictionary:dict[@"speaker"] forMeeting:meeting]; 
     } 
     else 
      [CoreDataManager insertMeetingWithDictionary:dict]; 
    } 

    [CoreDataManager saveContext]; 
} 

とクラスで更新

+ (void) insertMeetingWithDictionary: (NSDictionary *) dict 
{ 
// NSLog(@"dict: %@", dict); 
    Meeting *meeting = [NSEntityDescription insertNewObjectForEntityForName:@"Meeting" inManagedObjectContext:[CoreDataManager managedObjectContext]]; 

    meeting.brand =   dict[@"brand"]; 
    meeting.category =  dict[@"category"]; 
    meeting.city =   dict[@"city"]; 
    meeting.closed =   @([dict[@"closed"] boolValue]); 
    meeting.date =   [Utilities dateFromDateTime:dict[@"date"]]; 
    meeting.dateString =  dict[@"dateString"]; 
    meeting.identification = @([dict[@"id"] intValue]); 
    meeting.initiative =  dict[@"initiative"]; 
    meeting.location =  dict[@"location"]; 
    meeting.notes =   dict[@"notes"]; 
    meeting.state =   dict[@"state"]; 
    meeting.timeZone =  dict[@"timeZone"]; 
    meeting.title =   dict[@"title"]; 
    meeting.type =   dict[@"type"]; 

    [meeting setUser:SessionManagerInstance.loggedUser]; 

    [CoreDataManager addOrInsertRepWithDictionary:dict[@"rep"] forMeeting:meeting]; 
    [CoreDataManager addSpeakerWithDictionary:dict[@"speaker"] forMeeting:meeting]; 
    [CoreDataManager insertGroupsFromArray:dict[@"questiongroups"] forMeeting:meeting]; 

} 

：ここでは、呼び出し方法（複数可）です

Meeting.hは（.Mで@dynamic使用）

#import <Foundation/Foundation.h> 
#import <CoreData/CoreData.h> 

@class Attendee, Group, Rep, Speaker, User; 

@interface Meeting : NSManagedObject 

@property (nonatomic, retain) NSString * brand; 
@property (nonatomic, retain) NSString * category; 
@property (nonatomic, retain) NSString * city; 
@property (nonatomic, retain) NSNumber * closed; 
@property (nonatomic, retain) NSDate * date; 
@property (nonatomic, retain) NSString * dateString; 
@property (nonatomic, retain) NSNumber * identification; 
@property (nonatomic, retain) NSString * initiative; 
@property (nonatomic, retain) NSString * location; 
@property (nonatomic, retain) NSNumber * needsToBeSubmitted; 
@property (nonatomic, retain) NSString * notes; 
@property (nonatomic, retain) NSString * state; 
@property (nonatomic, retain) NSString * timeZone; 
@property (nonatomic, retain) NSString * title; 
@property (nonatomic, retain) NSString * transactionId; 
@property (nonatomic, retain) NSString * type; 
@property (nonatomic, retain) NSSet *attendees; 
@property (nonatomic, retain) NSSet *groups; 
@property (nonatomic, retain) Rep *rep; 
@property (nonatomic, retain) Speaker *speaker; 
@property (nonatomic, retain) User *user; 
@end 

@interface Meeting (CoreDataGeneratedAccessors) 

- (void)addAttendeesObject:(Attendee *)value; 
- (void)removeAttendeesObject:(Attendee *)value; 
- (void)addAttendees:(NSSet *)values; 
- (void)removeAttendees:(NSSet *)values; 
- (void)addGroupsObject:(Group *)value; 
- (void)removeGroupsObject:(Group *)value; 
- (void)addGroups:(NSSet *)values; 
- (void)removeGroups:(NSSet *)values; 

@end 

Speaker.h（using ）.Mで@dynamic

#import <Foundation/Foundation.h> 
#import <CoreData/CoreData.h> 


@interface Speaker : NSManagedObject 

@property (nonatomic, retain) NSString * degree; 
@property (nonatomic, retain) NSString * firstName; 
@property (nonatomic, retain) NSNumber * identification; 
@property (nonatomic, retain) NSString * lastName; 
@property (nonatomic, retain) NSString * preTitle; 
@property (nonatomic, retain) NSString * version; 
@property (nonatomic, retain) NSSet *meeting; 
@end 

@interface Speaker (CoreDataGeneratedAccessors) 

- (void)addMeetingObject:(NSManagedObject *)value; 
- (void)removeMeetingObject:(NSManagedObject *)value; 
- (void)addMeeting:(NSSet *)values; 
- (void)removeMeeting:(NSSet *)values; 

@end

NSKnownKeysDictionary1の言及はほぼ確実にこの行ことを意味します

[CoreDataManager fetchObjects:@"Meeting" withSortDescriptors:nil andPredicate:predicate]; 

...が、結果の型がNSDictionaryResultTypeでフェッチ要求を行っています。つまり、meetArray[0]は辞書であり、管理オブジェクトではありません。表示されているエラーの原因となるsetSpeakerメソッドはありません。

何らかの理由でディクショナリにする必要がない限り、フェッチ要求を変更して管理オブジェクトを返すことができます。しかし、あなたはこのような辞書を使うことはできません。
