我遇到了一个奇怪的错误... 我有一个类扩展另一个,从它得到一些变量。它非常简单。 当我编译模拟器的代码时,它工作得很好。当我在Iphone上运行时,会出现一个错误,指出可放弃的内容没有设置!代码: 父类的头:在模拟器上继承工作,但不在iPhone上!

#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 

父类的实现:

#import "GenericTarefaTableView.h" 


@implementation GenericTarefaTableView 
@synthesize tarefaMap,tarefaMapOriginal; 


@end 

子类的头:

@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!!!!!"); 
} 
} 

这款C ompiles罚款在模拟器上,但是当我尝试在iPhone上,我得到一个错误说,变量tarefaMap是未申报的,并应在功能上声明...

任何想法?

尝试'[self.tarefaMapOriginal isEqual:方法self.tarefaMap]',也发布确切的错误和它发生什么线。这有帮助。 – 2011-04-01 13:37:38

这个问题可能来自于您的模拟器版本默认保护的变量以及您的iphone版本中的@private。这只是一个猜测,因为我不知道你会怎么做。 – 2011-04-01 13:38:36

@interface EditTarefaViewController : GenericTarefaTableView <UITextFieldDelegate , UITextViewDelegate> { 

在该行之前添加此

@class GenericTarefaTableView; 

然后在.m文件添加

import "GenericTarefaTableView.h" 

,并在此之前,改变像viewDidLoad中

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


@implementation EditTarefaViewController 

u必须导入TarefaMap.h,并在EditTaref中声明与aViewController.h文件中像这样

@class TarefaMap;
