Question

How do I load an HTML file into my app (xcode)? I’m using the following code:

- (void)viewDidLoad
{
    [super viewDidLoad];
    [webView loadRequest:[NSURLRequest requestWithURL:[NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:@"index" ofType:@"html"]isDirectory:NO]]]; 
}

When I start the app, I only see a white page. What’s wrong?

.h file:

#import <UIKit/UIKit.h>

@interface poules : UIViewController {
    IBOutlet  UIWebView *webView;
}
@property (nonatomic,retain) UIWebView *webView;
@end

Here is a working example from one of my projects. My index.html file is in a folder called Documentation/html in the resources directory. Its important to note that these are “folder references“, not groups (hence the blue icon):

then to load it in a webView:

NSString *resourceDir = [[NSBundle mainBundle] resourcePath];
NSArray *pathComponents = [NSArray arrayWithObjects:resourceDir, @"Documentation", @"html", @"index.html", nil];
NSURL *indexUrl = [NSURL fileURLWithPathComponents:pathComponents];
NSURLRequest *req = [NSURLRequest requestWithURL:indexUrl];
[webView loadRequest:req];
