nil string parameter

[Shades of Chaos]

Hey all,

I am getting an error when I try to read a local file

'*** -[NSURL initFileURLWithPath:isDirectory:]: nil string parameter'

The code I am using to try an read the file is

[webView loadRequest:
	[NSURLRequest requestWithURL:
	 [NSURL fileURLWithPath:
	  [[NSBundle mainBundle]
	   pathForResource:@"/html/index" 
	   ofType:@"html"]
				isDirectory:NO]]];

html is a folder in my project folder and index is the file i am trying to read. I'm not quite sure what is wrong. If someone could help me out that would be great.

Thanks
Clinton

Troubleshooting step 1: Break those out into separate lines.

Troubleshooting step 2: Use logs to identify the value at each line, and see where things go wrong.

Ok so the pathForResource is null but I don't know how to fix.

[BrianSlick]

pathForResource:ofType:
Returns the full pathname for the resource identified by the specified name and file extension.

- (NSString *)pathForResource:(NSString *)name ofType:(NSString *)extension
Parameters
name
The name of the resource file.

And if that doesn't work:

pathForResource:ofType:inDirectory:
Returns the full pathname for the resource identified by the specified name and file extension and located in the specified bundle subdirectory.

- (NSString *)pathForResource:(NSString *)name ofType:(NSString *)extension inDirectory:(NSString *)subpath
Parameters
name
The name of the resource file.

extension
If extension is an empty string or nil, all the files in subpath and its subdirectories are returned. If an extension is provided the subdirectories are not searched.

subpath
The name of the bundle subdirectory. Can be nil.

So it is probably not searching in the write area. How do it get it to search in the write area?

NAME. Not path, NAME.

Even when I say

	[webView loadRequest:[NSURLRequest requestWithURL:[NSURL fileURLWithPath:[[NSBundle mainBundle]pathForResource:@"index" ofType:@"html"] isDirectory:NO]]];

I still get the same error.

[BrianSlick]

You're not even using the right code now.

[Shades of Chaos]

It is the same code i was using before

[BrianSlick]

Ok, so reread post #4. All of it.

[Shades of Chaos]

index is the name of the resource file. I tried changing the isDirectory to inDirectory and the same error came up. When I was using inDirectory:YES the app would crash without explanation.

[BrianSlick]

Good lord.

NSString *path = [[NSBundle mainBundle] pathForResource:@"index" ofType:@"html" inDirectory:@"html"];
NSURL *url = [NSURL fileURLWithPath:path];
NSURLRequest *request = [NSURLRequest requestWithURL:url];
[webView loadRequest:request];

Your license to pack a whole bunch of crap into a single line of code is hereby revoked.

[Shades of Chaos]

I still got the same error with your code

[BrianSlick]

Are you able to solve problems on your own?
