Unrecognized selector sent to instance

Code:

[fileTemplate writeToFile:writablePath atomically:YES encoding:NSUTF8StringEncoding error:NULL];

This is the line in question.

Just for clarity:

Code:

fileTemplate = [NSString stringWithFormat:@"<!DOCTYPE html PUBLIC \"-//W3C//DTD XHTML 1.0 Transitional//EN\" \"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd\">\n<html xmlns=\"http://www.w3.org/1999/xhtml\">\n<head>\n<meta http-equiv=\"Content-Type\" content=\"text/html; charset=UTF-8\" />\n<title>Untitled Document</title>\n</head>\n\n<body>\n</body>\n</html>"];

and

Code:

WritablePath = [NSString stringWithFormat:@"/Users/Prince/Library/Application Support/iPhone Simulator/3.2/Applications/3A8069CB-526D-4F65-9F29-8939B250431E/Documents/Project/index.txt"];

Obviously WritablePath uses a different way to get the path, but I NSLogged it, and got that...

Check your capitalisation, you're passing "writablePath" with a lowercase w, yet your NSString pointer is "WritablePath" with an uppercase w.

Also, you don't have to use stringWithFormat unless you're actually formatting something.
For example, you can just use:

Code:

WritablePath = @"/Users/Prince/Library/Application Support/iPhone Simulator/3.2/Applications/3A8069CB-526D-4F65-9F29-8939B250431E/Documents/Project/index.txt";

Ah, that would throw me a compile error, I just had to edit the method names because some people wouldn't approve.

I'll try that thing.

It worked, I have no idea why though.

How would I check when the operation has been completed?

It returns a BOOL, so you can use:

Code:

BOOL didSucceed = [whatever writeToFile...];
if (didSucceed){
    NSLog(@"yep");
}
