Question

我有这个方法将html文件从我的应用程序加载到UIWebView中。问题是这个文件名不时改变 - 我无法让它工作。这是我的代码：

    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]];

我遇到了这个问题：[NSURL initFileURLWithPath:]: nil string parameter.

当我以这种方式使用它的工作时：

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]];

我应该怎么做才能解决这个问题？谢谢！

这是整个方法：希望你能帮助我。

   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]];

好的，问题是我想要关注并忘记将html文件添加到我的项目中。所以在将来的某个时候需要这些代码的所有人 - 它的工作完美。

NSUserDefaults * defaults = [NSUserDefaults standardUserDefaults]; NSString * zodiacProfile = [默认值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]];

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