iOS - 架构i386的3个重复符号

问题描述

我有一个问题了解链接器命令错误。我收到以下内容：

I am having an issue understanding a linker command error. I am receiving the following:

duplicate symbol _OBJC_IVAR_$_XYZAddToDoItemViewController._toDoItem in:
/Users/*/Library/Developer/Xcode/DerivedData/ToDoToday-fjyijxlbvauebmeuhtgdvdrjtfez/Build/Intermediates/ToDoToday.build/Debug-iphonesimulator/ToDoToday.build/Objects-normal/i386/XYZToDoListViewController.o

ld: 3 duplicate symbols for architecture i386
clang: error: linker command failed with exit code 1 (use -v to see invocation)

我不知道Xcode正是指哪些符号。以下是实施文件的顶部。

I'm not sure which symbols Xcode is referring to exactly. Below are the top of the implementation files.

XYZToDoListViewController.m：

XYZToDoListViewController.m:

#import "XYZAddToDoItemViewController.h"
@interface XYZAddToDoItemViewController ()
@property NSMutableArray *toDoItems;
@end
@implementation XYZAddToDoItemViewController

XYZAddToDoItemViewController.m：

XYZAddToDoItemViewController.m:

#import "XYZAddToDoItemViewController.h"
@interface XYZAddToDoItemViewController ()
@property (weak, nonatomic) IBOutlet UITextField *textField;
@property (weak, nonatomic) IBOutlet UIBarButtonItem *doneButton;
@end
@implementation XYZAddToDoItemViewController

任何帮助将不胜感激，谢谢您。

Any help would be much appreciated, thank you.

推荐答案

在您的 XYZToDoListViewController.m 更改：

@interface XYZAddToDoItemViewController ()

to：

@interface XYZToDoListViewController ()

和：

@implementation XYZAddToDoItemViewController

to：

@implementation XYZToDoListViewController

和：

#import "XYZAddToDoItemViewController.h"

to：

#import "XYZToDoListViewController.h"

基本上你在 XYZToDoListViewController.m 文件中有错误的类名。

Basically you have the wrong class name in the XYZToDoListViewController.m file.

让你不要在 XYZToDoListViewController.h 文件中也有同样的错误。

Make you don't have the same mistake in the XYZToDoListViewController.h file.
