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选择的表格视图。它在使用以下方法进行本地化之前有效。
- (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;
}
通过添加日语本地化文件并将上述内容更改为：
来对其进行本地化- (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;
}
崩溃时出现以下错误：

关于如何为所选语言调用SelectCategoryViewController的任何建议？
答案 0 :(得分：0)
这条线对我来说不对：
NSBundle *myLocalizedBundle=[NSBundle bundleWithPath:[NSString stringWithFormat:[[NSBundle mainBundle]bundlePath],"en.lproj"]];
你可能意味着这样的事情：
NSString* path= [[NSBundle mainBundle] pathForResource:@"en" ofType:@"lproj"];
NSBundle* bundle:myLocalizedBundle = [NSBundle bundleWithPath:path];
SelectCategoryViewController *viewTwo = [[SelectCategoryViewController alloc] initWithNibName:@"SelectCategoryViewController" bundle:myLocalizedBundle];
这里将对此进行更多讨论：Manually loading a different localized nib in iOs
请注意，仅当您要进行应用内语言选择时才需要这样做。本地化通常应使用iOS设备选择的语言，在这种情况下，所有这些都更直接（您只需让iOS为您选择捆绑包）。
答案 1 :(得分：0)
xcode 5： 我不得不清理构建，清理构建文件夹，删除派生数据，重置模拟器，关闭模拟器，关闭Xcode。
再次打开项目，它正在运行。
答案 2 :(得分：0)
问题 - 这是项目路径的问题，我认为[self.window makeWindowKeyVisible]无法找到第一个指定控制器的路径... 解决方案 - 当项目突然停止工作时，它会发生一段时间，所以不用担心 - 只需将项目转移到其他路径，或者只是更改项目所在的文件夹名称，它将开始正常工作....
它对我有效...
