無法加載「路徑」與「stringWithFormat」objective-c

我有這種方法，從我的應用程序加載HTML文件到UIWebView。問題是這個文件名不時變化 - 我無法讓它工作。這是我的代碼：無法加載「路徑」與「stringWithFormat」objective-c

NSString *path; 
    NSBundle *thisBundle = [NSBundle mainBundle]; 
    path = [thisBundle pathForResource:[NSString stringWithFormat:@"%@_file",MyFileNameString] ofType:@"htm"]; 

// make a file: URL out of the path 
    NSURL *instructionsURL = [NSURL fileURLWithPath:path]; 
    [ProfileHtml loadRequest:[NSURLRequest requestWithURL:instructionsURL]];

和我得到這個問題：當我以這種方式使用它，例如其工作[NSURL initFileURLWithPath:]: nil string parameter.

：

NSString *path; 
NSBundle *thisBundle = [NSBundle mainBundle]; 
path = [thisBundle pathForResource:[NSString stringWithFormat:@"%@_file",@"amir"] ofType:@"htm"]; 

// make a file: URL out of the path 
NSURL *instructionsURL = [NSURL fileURLWithPath:path]; 
[ProfileHtml loadRequest:[NSURLRequest requestWithURL:instructionsURL]];

我應該怎麼做才能解決這個問題？謝謝！

這是整個方法：希望你能幫助我。

NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults]; 
     NSString *zodiacProfile = [defaults valueForKey:@"zodiacProfile"];  

     NSLog(@"zodiacProfile: %@",zodiacProfile); 
     [zodiacWallpaper setImage:[UIImage imageNamed:[NSString stringWithFormat:@"Wallpaper_%@",zodiacProfile]]]; 
     zodiacTitle.text = [NSString stringWithFormat:@"About %@",zodiacProfile]; 

     NSString *path; 
     NSBundle *thisBundle = [NSBundle mainBundle]; 
     path = [thisBundle pathForResource:[NSString stringWithFormat:@"%@HTM",zodiacProfile] ofType:@"htm"]; 

     NSURL *instructionsURL = [NSURL fileURLWithPath:path]; 

     NSLog(@"zodiac: %@",zodiacProfile); 
     NSLog(@"path: %@",path); 
     NSLog(@"url: %@",instructionsURL); 

     [ProfileHtml loadRequest:[NSURLRequest requestWithURL:instructionsURL]];

那麼'MyFileNameString'的內容呢？如果這是工作和不工作之間的唯一區別，那就是問題所在。 – trojanfoe 2012-03-22 15:43:15

在你的第一個例子中，你確定'MyFileNameString'被設置爲你認爲的值嗎？你確定你的捆綁包中有這個名字的文件嗎？ – jonkroll 2012-03-22 15:43:49

在構建應用程序（複製文件構建階段）之前，您確定所有htm文件都已添加到正確的目標嗎？ – Alladinian 2012-03-22 15:51:19

好的，問題是，我想要的焦點和忘記將html文件添加到我的項目。對於將來需要此代碼的所有人來說 - 它的工作非常完美。

NSUserDefaults * defaults = [NSUserDefaults standardUserDefaults]; NSString * zodiacProfile = [defaults valueForKey：@「zodiacProfile」];

NSLog(@"zodiacProfile: %@",zodiacProfile); 
    [zodiacWallpaper setImage:[UIImage imageNamed:[NSString stringWithFormat:@"Wallpaper_%@",zodiacProfile]]]; 
    zodiacTitle.text = [NSString stringWithFormat:@"About %@",zodiacProfile]; 

    NSString *path; 
    NSBundle *thisBundle = [NSBundle mainBundle]; 
    path = [thisBundle pathForResource:[NSString stringWithFormat:@"%@HTM",zodiacProfile] ofType:@"htm"]; 

    NSURL *instructionsURL = [NSURL fileURLWithPath:path]; 

    NSLog(@"zodiac: %@",zodiacProfile); 
    NSLog(@"path: %@",path); 
    NSLog(@"url: %@",instructionsURL); 

    [ProfileHtml loadRequest:[NSURLRequest requestWithURL:instructionsURL]];
