Question

When I run the code below

NSString *chemin;
    chemin = [NSString stringWithFormat:@"chapitre0%d", [sender tag]];
    NSLog(@"chemin : %@",chemin);

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

I got :
‘NSInvalidArgumentException’, reason: ‘* -[NSURL initFileURLWithPath:isDirectory:]: nil string parameter’

but *chemin is initialized to the right value in the log.

Certainly a noob question,
Thx for your help

Answer 1

This could be it, the chemin variable might have the correct chapter but the path might be wrong. So when you pass the wrong filepath to NSURL it would have returned null which inturn would have caused the crash.

First get the absolute path like so –

NSString *path   = [[NSBundle mainBundle] pathForResource:@"chapter1" ofType:@"html"];
