Question

我是iOS新手，我使用Xcode 4.3.2，我用tabView创建了一个项目，默认情况下它有两个视图控制器。我现在正在创建一个新的，

ThirdView.h

#import <UIKit/UIKit.h>

@interface ThirdView : UIViewController

@end


#import "ThirdView.h"

@implementation ThirdView

- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
    self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
    if (self) {
        self.title = NSLocalizedString(@"Third", @"Third");
        self.tabBarItem.image = [UIImage imageNamed:@"Third"];
    }
    return self;
}

- (void)viewDidLoad
{
    [super viewDidLoad];
    // Do any additional setup after loading the view, typically from a nib.
}

- (void)viewDidUnload
{
    [super viewDidUnload];
    // Release any retained subviews of the main view.
}

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
    if ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPhone) {
        return (interfaceOrientation != UIInterfaceOrientationPortraitUpsideDown);
    } else {
        return YES;
    }
}


@end

并在appDelicate.m

中

viewController3 = [[ThirdView alloc] initWithNibName:@"ThirdView" bundle:nil];

并将viewController3添加到tabBarController。

self.tabBarController.viewControllers = [NSArray arrayWithObjects:viewController1, viewController2, viewController3 ,nil];

问题是：当我在设备中执行代码时，我可以看到第三个选项卡，但是当我点击它时，它会崩溃。我在哪里做错了？

仔细检查nib文件中第三个视图控制器的类名。

将viewController添加到标签栏控制器崩溃
