我正在创建我的第一个 iPhone 应用程序,其中第一个屏幕显示用户从中选择的表格视图。它使用以下方法在本地化之前工作。
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
// Override point for customization after application launch.
navigationController = [[UINavigationController alloc] init];
[self.window addSubview:[self.navigationController view]];
if(self.selectCategoryViewController == nil)
{
SelectCategoryViewController *viewTwo = [[SelectCategoryViewController alloc] initWithNibName:@"SelectCategoryViewController" bundle:[NSBundle mainBundle]];
self.selectCategoryViewController = viewTwo;
[viewTwo release];
}
[self.navigationController setNavigationBarHidden:YES];//this will hide the navigation bar
[self.navigationController pushViewController:self.selectCategoryViewController animated:YES];
//self.window.rootViewController = self.navigationController;
[self.window makeKeyAndVisible];
return YES;
}
在我通过添加日语本地化文件并将上面的内容更改为以下方式对其进行本地化之后:
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
// Override point for customization after application launch.
navigationController = [[UINavigationController alloc] init];
[self.window addSubview:[self.navigationController view]];
if(self.selectCategoryViewController == nil)
{
NSBundle *myLocalizedBundle=[NSBundle bundleWithPath:[NSString stringWithFormat:[[NSBundle mainBundle]bundlePath],"en.lproj"]];
NSLog(@"the localized bundle is %@",myLocalizedBundle);
SelectCategoryViewController *viewTwo=[[SelectCategoryViewController alloc] initWithNibName:@"SelectCategoryViewController" bundle:myLocalizedBundle];
self.selectCategoryViewController = viewTwo;
[viewTwo release];
}
[self.navigationController setNavigationBarHidden:YES];//this will hide the navigation bar
[self.navigationController pushViewController:self.selectCategoryViewController animated:YES];
[self.window makeKeyAndVisible];
return YES;
}
它崩溃并出现以下错误:

关于我应该如何为所选语言调用 SelectCategoryViewController 的任何建议?
