iOS Question

iOS download and save HTML file

I am trying to download a webpage (html) then display the local html that has been download in a UIWebView.

This is what I have tried -

NSString *stringURL = @"url to file";
NSURL *url = [NSURL URLWithString:stringURL];
NSData *urlData = [NSData dataWithContentsOfURL:url];
if ( urlData )
{
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];

NSString *filePath = [NSString stringWithFormat:@"%@/%@", documentsDirectory,@"index.html"];
[urlData writeToFile:filePath atomically:YES];
}

//Load the request in the UIWebView.
[web loadRequest:[NSURLRequest requestWithURL:[NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:@"index" ofType:@"html"]isDirectory:NO]]]; // Do any additional setup after loading the view from its nib.


But this gives a 'SIGABRT' error.

Not too sure what I have done wrong?

Any help would be appreciated. Thanks!

Answer

The path passed to the UIWebView is incorrect, like Freerunnering mentioned, try this instead:

// Determile cache file path
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *filePath = [NSString stringWithFormat:@"%@/%@", [paths objectAtIndex:0],@"index.html"];   

// Download and write to file
NSURL *url = [NSURL URLWithString:@"http://www.google.nl"];
NSData *urlData = [NSData dataWithContentsOfURL:url];
[urlData writeToFile:filePath atomically:YES];

// Load file in UIWebView
[web loadRequest:[NSURLRequest requestWithURL:[NSURL fileURLWithPath:filePath]]];      

Note: Correct error-handling needs to be added.
