编译多控制器项目时的奇怪行为

Question

我有一些代码如下

#import <UIKit/UIKit.h>
@interface ViewMoreSettingController : UIViewController <  UITableViewDelegate,     UITableViewDataSource >
{}

@end


#import "ViewMoreSettingController.h"

@implementation ViewMoreSettingController
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
if (self) {
    // Custom initialization
}
return self;
}
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view.
}
- (void)viewDidUnload
{
[super viewDidUnload];
// Release any retained subviews of the main view.
}
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
return (interfaceOrientation == UIInterfaceOrientationPortrait);
}
@end

//"MoreController.h"

#import <UIKit/UIKit.h>
@class ViewMoreSettingController;

@interface MoreController : UIViewController  <UITableViewDataSource,UITableViewDelegate>{

ViewMoreSettingController *vViewMoreSettingController;
}

@property (retain,nonatomic) ViewMoreSettingController *vViewMoreSettingController;
@end

//------------------------------"MoreController.m"

#import "MoreController.h"
#import "ViewMoreSettingController.h"

@implementation MoreController
@synthesize vViewMoreSettingController;
-(void)doSomething
{

        ViewMoreSettingController * temController ;
        temController=[[ViewMoreSettingController alloc]initWithNibName:@"ViewMoreSetting" bundle:nil];//a: if remove this line it will compile successfully
        [self.navigationController  pushViewController:vViewMoreSettingController animated:YES];

        [temController release];



   }

它将报告

体系结构i386的未定义符号："_OBJC_CLASS_$_ViewMoreSettingController"，引用自：MoreController.o中的objc类refld:找不到体系结构i386的符号clang:错误：链接器命令失败，退出代码为1（使用-v查看调用）

如果我删除行a:它将成功编译。

欢迎任何评论

我们最近也遇到了同样的情况。简单的解决方案是仅通过删除引用从项目中删除这些文件，然后再次将这些文件添加到项目中，因为添加现有文件将解决问题。
