Question

我遇到了一个奇怪的错误...... 我有一个扩展另一个类的类，从中获取一些变量。这是一个非常简单的。当我编译模拟器的代码时，它工作得很好。当我在Iphone中运行时，它会收到一个错误，指出没有设置vairable！代码：父类标题：

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


@interface GenericTarefaTableView : UITableViewController {
TarefaMap* tarefaMap;
TarefaMap* tarefaMapOriginal;
}
@property (nonatomic, retain) TarefaMap* tarefaMap;
@property (nonatomic, retain) TarefaMap* tarefaMapOriginal;


@end

父类实现：

#import "GenericTarefaTableView.h"


@implementation GenericTarefaTableView
@synthesize tarefaMap,tarefaMapOriginal;


@end

子类标题：

@interface EditTarefaViewController : GenericTarefaTableView <UITextFieldDelegate , UITextViewDelegate> {

Tarefa* tarefa;
NSArray *fieldLabels;
UITextField *textFieldBeginEdited;
BOOL isEdit;
IBOutlet UITableViewCell *cell0;
IBOutlet UITextView* textView;
NSManagedObjectContext* context;



}

@property (nonatomic, retain)  NSManagedObjectContext* context;
@property (nonatomic, retain) IBOutlet UITextView* textView;
@property (nonatomic, retain) IBOutlet UITableViewCell *cell0;
@property (nonatomic, retain) Tarefa* tarefa;
@property (nonatomic, retain) UITextField* firstField;
@property (nonatomic, retain) NSArray *fieldLabels;
@property (nonatomic, retain) UITextField *textFieldBeingEdited;

@end

子类实现：

#import "EditTarefaViewController.h"

@implementation EditTarefaViewController



@synthesize tarefa, textFieldBeingEdited,firstField,fieldLabels,textView, cell0, context;
NSMutableArray *textFieldarray;
UIActionSheet *actionSheet;
UITableViewCell* cell1;


- (void)viewDidLoad
{


NSLog(@"ViewDidLoad");
[super viewDidLoad];
self.tarefaMap=[[TarefaMap alloc] initWithTarefa:tarefa];
self.tarefaMapOriginal=[[TarefaMap alloc] initWithTarefa:tarefa];

if ([tarefaMapOriginal isEqual:tarefaMap]) {
    NSLog(@"SOMOS IGUAIS!!!!!");
}
   NSLog(@"Comparando tarefas!!!!!");
if ([tarefaMapOriginal isEqualtoTarefaMap:tarefaMap]) {
    NSLog(@"SOMOS IGUAIS2!!!!!");
}
}

这在模拟器上编译很好，但是当我尝试使用iPhone时，我收到一个错误，说变量tarefaMap未声明，应该在函数上声明......

有什么想法吗？

@interface EditTarefaViewController : GenericTarefaTableView <UITextFieldDelegate , UITextViewDelegate> {

在该行之前

添加此

@class GenericTarefaTableView;

然后在.m文件中添加

import "GenericTarefaTableView.h"

并在viewdidload中更改

NSLog(@"ViewDidLoad");
[super viewDidLoad];
super.tarefaMap=[[TarefaMap alloc] initWithTarefa:tarefa];
super.tarefaMapOriginal=[[TarefaMap alloc] initWithTarefa:tarefa];


@implementation EditTarefaViewController

之前你必须导入TarefaMap.h并在EditTarefaViewController.h文件中声明这个，如下所示

@class TarefaMap;

继承在模拟器上工作但不在Iphone上工作！
