在.h文件中聲明的實體的訪問屬性

Question

我是xcode的新手，正在嘗試使用我沒有編寫的代碼。非常抱歉，如果這是一個愚蠢的問題！

運行我的代碼後，我在這裏創建實體（實體由Entities.h定義）：

Entities *proxy = [[Entities alloc]initWithUri:@"http://localhost:8080/Resource/example.svc" credential:nil]; 
DataServiceQuery *qry = [proxy person]; 
QueryOperationResponse *result = [qry execute]; 
items = [result getResult]; 
NSLog(@"items size: %@", items); 

這個偉大的工程，並打印如下：

然而，我沒有IDEA如何訪問Model_person中的變量。

從Entities.h相關的代碼是：

/** 
* @interface:person 
* @Type:EntityType 

* @key:person_id* 
*/ 
@interface Model_person : ODataObject 
{ 

/** 
* @Type:EntityProperty 
* @EdmType:Edm.Int32 
*/ 
NSNumber *m_person_id; 

/** 
* @Type:EntityProperty 
* @EdmType:Edm.String 
* @MaxLength:255 
* @FixedLength: 
*/ 
NSString *m_person_role; 

/** 
* @Type:EntityProperty 
* @EdmType:Edm.String 
* @MaxLength:255 
* @FixedLength: 
*/ 
NSString *m_person_firstname; 

/** 
* @Type:EntityProperty 
* @EdmType:Edm.Int32 
*/ 
NSNumber *m_person_department; 

/** 
* @Type:EntityProperty 
* @EdmType:Edm.Int32 
*/ 
NSNumber *m_person_contractor; 

/** 
* @Type:EntityProperty 
* @EdmType:Edm.Int32 
*/ 
NSNumber *m_person_supervisor; 

/** 
* @Type:EntityProperty 
* @EdmType:Edm.Int32 
*/ 
NSNumber *m_person_admin; 

/** 
* @Type:EntityProperty 
* @EdmType:Edm.Int32 
*/ 
NSNumber *m_person_workweek; 

/** 
* @Type:EntityProperty 
* @EdmType:Edm.String 
* @MaxLength:255 
* @FixedLength: 
*/ 
NSString *m_person_employee_id; 

/** 
* @Type:EntityProperty 
* @EdmType:Edm.Int32 
*/ 
NSNumber *m_person_billrate; 

/** 
* @Type:EntityProperty 
* @EdmType:Edm.String 
* @MaxLength:255 
* @FixedLength: 
*/ 
NSString *m_person_lastname; 

/** 
* @Type:EntityProperty 
* @EdmType:Edm.Int32 
*/ 
NSNumber *m_person_active; 

} 


@property (nonatomic , retain , getter=getperson_id , setter=setperson_id :)NSNumber *m_person_id; 
@property (nonatomic , retain , getter=getperson_role , setter=setperson_role :) NSString *m_person_role; 
@property (nonatomic , retain , getter=getperson_firstname , setter=setperson_firstname :) NSString *m_person_firstname; 
@property (nonatomic , retain , getter=getperson_department , setter=setperson_department :)NSNumber *m_person_department; 
@property (nonatomic , retain , getter=getperson_contractor , setter=setperson_contractor :)NSNumber *m_person_contractor; 
@property (nonatomic , retain , getter=getperson_supervisor , setter=setperson_supervisor :)NSNumber *m_person_supervisor; 
@property (nonatomic , retain , getter=getperson_admin , setter=setperson_admin :)NSNumber *m_person_admin; 
@property (nonatomic , retain , getter=getperson_workweek , setter=setperson_workweek :)NSNumber *m_person_workweek; 
@property (nonatomic , retain , getter=getperson_employee_id , setter=setperson_employee_id :) NSString *m_person_employee_id; 
@property (nonatomic , retain , getter=getperson_billrate , setter=setperson_billrate :)NSNumber *m_person_billrate; 
@property (nonatomic , retain , getter=getperson_lastname , setter=setperson_lastname :) NSString *m_person_lastname; 
@property (nonatomic , retain , getter=getperson_active , setter=setperson_active :)NSNumber *m_person_active; 

+ (id) Createperson; 
- (id) init; 
- (id) initWithUri:(NSString*)anUri; 
@end 

注： 我試圖訪問元素的cellForRowAtIndexPath後續的方式：

Entities *event = [items objectAtIndex:indexPath.row]; 
cell.textLabel.text = [[[event getperson] objectAtIndex: 0] getName]; 

丟給一個錯誤說「不'DataServiceQuery'的可見@interface聲明選擇器'ObjectAtIndex'「

UPDATE：

getperson也被定義在Entities.h：

/** 
* Container interface Entities, Namespace: Model 
*/ 
@interface Entities : ObjectContext 
{ 
NSString *m_OData_etag; 

    DataServiceQuery *m_member; 

    DataServiceQuery *m_cumulative; 

    DataServiceQuery *m_date; 

    DataServiceQuery *m_holiday; 

    DataServiceQuery *m_associations; 

    DataServiceQuery *m_department; 

    DataServiceQuery *m_person; 

    DataServiceQuery *m_project; 

} 

@property (nonatomic , retain , getter=getEtag , setter=setEtag :)NSString *m_OData_etag; 

@property (nonatomic , retain , getter=getmember , setter=setmember :) DataServiceQuery *m_member; 

@property (nonatomic , retain , getter=getcumulative , setter=setcumulative :) DataServiceQuery *m_cumulative; 

@property (nonatomic , retain , getter=getdate , setter=setdate :) DataServiceQuery *m_date; 

@property (nonatomic , retain , getter=getholiday , setter=setholiday :) DataServiceQuery *m_holiday; 

@property (nonatomic , retain , getter=getassociations , setter=setassociations :) DataServiceQuery *m_associations; 

@property (nonatomic , retain , getter=getdepartment , setter=setdepartment :) DataServiceQuery *m_department; 

@property (nonatomic , retain , getter=getperson , setter=setperson :) DataServiceQuery *m_person; 

@property (nonatomic , retain , getter=getproject , setter=setproject :) DataServiceQuery *m_project; 

- (id) init; 
- (id) initWithUri:(NSString*)anUri credential:(id)acredential; 
- (id) member; 
- (id) cumulative; 
- (id) date; 
- (id) holiday; 
- (id) associations; 
- (id) department; 
- (id) person; 
- (id) project; 
- (void) addTomember:(id)anObject; 
- (void) addTocumulative:(id)anObject; 
- (void) addTodate:(id)anObject; 
- (void) addToholiday:(id)anObject; 
- (void) addToassociations:(id)anObject; 
- (void) addTodepartment:(id)anObject; 
- (void) addToperson:(id)anObject; 
- (void) addToproject:(id)anObject;

我想你應該寫的財產以後這樣的：

Model_person* modelPerson = [items objectAtIndex:indexPath.row]; 
cell.textLabel.text = modelPerson.getperson_firstname; 

，而不是

Entities *event = [items objectAtIndex:indexPath.row]; 
cell.textLabel.text = [[[event getperson] objectAtIndex: 0] getName];
