xib文件本地化後iPhone應用程序崩潰

Question

我正在創建我的第一個iPhone應用程序，其中第一個屏幕顯示用戶從中選擇的表格視圖。它使用下面的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; 
} 

後，我加入了日語本地化文件，並改變上述這種本地化它：

- (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; 
} 

它與下面的錯誤崩潰：

terminate called after throwing an instance of 'NSException' 

如何我任何建議應該爲所選語言調用SelectCategoryViewController？

Answer 1

這行看起來我錯了：

NSBundle *myLocalizedBundle=[NSBundle bundleWithPath:[NSString stringWithFormat:[[NSBundle mainBundle]bundlePath],"en.lproj"]]; 

你大概意思是這樣的：

NSString* path= [[NSBundle mainBundle] pathForResource:@"en" ofType:@"lproj"]; 
NSBundle* bundle:myLocalizedBundle = [NSBundle bundleWithPath:path]; 
SelectCategoryViewController *viewTwo = [[SelectCategoryViewController alloc] initWithNibName:@"SelectCategoryViewController" bundle:myLocalizedBundle]; 

這更是這裏討論：Manually loading a different localized nib in iOs

注意，這僅在需要您想要進行應用內語言選擇。本地化應該通常使用iOS設備的選定語言，在這種情況下，所有這些都更加直接（您只需讓iOS爲您選擇軟件包）。

Answer 2

xcode 5： 我不得不清理build，clean build文件夾，刪除派生數據，重置模擬器，關閉模擬器，關閉Xcode。

再次打開項目，它的工作。

Answer 3

問題 - 這是一個項目路徑的問題，我認爲[self.window makeWindowKeyVisible]無法找到您的第一個分配的控制器的路徑... 解決方案 - 發生一段時間，當您的項目突然停止工作，所以不用擔心 - 只需將項目轉移到其他路徑，或者只是更改項目所在的文件夾的名稱，並且它將開始正常工作....

它對我成功工作...
