无法使用“ stringWithFormat” objective-c加载“ path”

Question

i have this method that load html file from my application into UIWebView. the issue is that this file name change from time to time - and i cant get it to work. this is my code:

    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]];

and i get this problem: [NSURL initFileURLWithPath:]: nil string parameter.

when i use it for example in this way its work:

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]];

Ok, the problem was that i want in focus and forgot to add the html files into my project. So to all of you who will need this code sometime in the future - its working perfect.

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]];
